Introduction
This user guide describes the installation and configuration processes of the SyncServer® S600/S650 v5.4 device.
SyncServer® S600
The Microchip SyncServer S600 device provides accurate, secure, and reliable time services that are required by all modern networks. The security-hardened S600 network time server is purpose-built to deliver the exact hardware-based Network Time Protocol (NTP) time stamps. The unparalleled accuracy and security are rounded out with outstanding ease-of-use features for a reliable network time service that meets your network and business operation needs.
SyncServer S650
The modular Microchip SyncServer S650 device combines the best of time and frequency instrumentation with unique flexibility and powerful network/security based features. The base Timing I/O module, with eight Bayonet Neill­Concelman (BNC) connectors, comes standard with the most popular timing I/O signals (IRIG B, 10 MHz, 1 PPS, and so on). When more flexibility is required, the unique Microchip FlexPortTM technology option enables six of the BNCs to output any supported signal (time codes, sine waves, programmable rates, and so on), all configurable in real time through the secure web interface. This incredibly flexible BNC-by-BNC configuration makes very efficient and cost-effective use of the 1U space available. Similar functionality is applied to the two input BNCs also. Unlike legacy modules with fixed count BNCs outputting fixed signal types per module, with FlexPort technology you can have up to 12 BNCs outputting any combination of supported signal types. This level of timing signal flexibility is unprecedented and can even eliminate the need for additional signal distribution chassis without degradation in the precise quality of the coherent signals.
SyncServer® S650i
The Microchip SyncServer S650i device is a S650 base chassis without a GNSS receiver.

1.2.4.2. Timing I/O Module with HaveQuick/PTTI Module Connections
The Timing I/O with the HaveQuick/PTTI module (090-15201-012) adds support to a set of timing protocols and signals, generally associated with the GPS User Equipment sector and timing interfaces intended for equipment interoperability. Within that sector, definitions for a Precise Time and Time-Interval (PTTI) interface cover an evolutionary range of signaling and protocols. A core set of revised documents (ICD-GPS-060) form the basis of the subject, including baseline HaveQuick and BCD interfaces and protocol definitions. This module supports many variations of this category of timing interfaces. References to STANAG (STANdard NATO AGreement) codes are variations of the core ICD-GPS-060A code.
Along with the unique HaveQuick/PTTI capabilities, this module supports all functionality that is available on J1­J6 of the standard Timing I/O module. Connections J7 and J8 uniquely provide balanced 2-wire PTTI BCD capabilities. The FlexPorts license is required to be purchased with the HaveQuick/PTTI module, and the license will be pre-installed on the shipped system containing a HaveQuick/PTTI module.

Notes:SyncServer S6x0 uses IRIG 1344 version C37.118.1a-2014.
· On the input side, the code performs a subtraction using control bits 14­19 from the supplied IRIG time with the expectation that this will produce UTC time. This aligns with the C37.118.1a-2014 definition.
· On the output side, control bits 14­ 19 is always zero, and the encoded IRIG time is UTC (if using an input 1344 IRIG as the reference the 2014 rules are applied to get that value). Therefore, any code receiving S6x0 IRIG 1344 output must work regardless of which version they are decoding (as there is nothing to add or subtract).
Configuration Management
SyncServer S6x0 can be configured using the Keypad interface, Web interface, Command Line interface, or using REST API v1 and v2.

This time is updated when it obtains time from a time reference, such as GNSS, IRIG, PTP, or NTP. The default value for the date is the software build date. This date is used for the first log entries when booting up the unit. The time changes to local time during the boot-up process, if a time zone has been configured.

number is entered from the keypad. For status displays, the left/right arrows can scroll horizontally when <previous:next> is displayed. · Up/Down Arrow Buttons: In status, scrolls a screen vertically, displays the previous/next screen · Number Buttons: Enters a number or selects a numbered menu item The following buttons change the function of the display: · TIME: Changes the format and contents of the time display · STATUS: Displays status of basic SyncServer operational conditions · MENU: Displays a menu of functions
The following sections describe the preceding three buttons in detail.
TIME Button
Cycling the TIME button changes the predefined format and contents of the time display:
· Large numeric time display on full screen. Hours:Minutes:Seconds · Medium numeric time display on the left, current reference, and NTP Stratum on the right · Small date and time, reference, and NTP stratum · The time display also indicates a time scale: · ­ If the time zone setting on the TIMING-Time Zone web page is set to UTC, the time display
shows UTC as the time scale ­ If the time zone setting on TIMING-Time Zone page is set to a non-UTC (local) time zone, the
time display leaves the time scale blank, or adds AM/PM if the user selects the 12-hour time scale. Click MENU and select 2) Display > 3) 12/24 > 1) 12 (AM/PM). ­ If the Ignore UTC Corrections from GPS Reference setting on the TIMING-HW Clock page is enabled (selected), then the time display shows GPS as the time scale
Note:The TIMING-Time Zone page configures the display for UTC or local time.
STATUS Button
Pressing the STATUS button repeatedly displays a series of status screens for the following options:

3.3.2. 3.3.3.

Some screens have a Next> in the upper right. This means that more information is available by pressing the right arrow button. This cycles through screens on that topic.
Network Time Protocol Status Screen
Stratum: It refers to the Stratum number of the SyncServer. Stratum 1 means it is locked to a Hardware clock.
Hardware Clock Input Reference is a Stratum 0 source. Stratum 2­15 means that SyncServer is locked to another Network Time Protocol (NTP) time source. Stratum 16 means that SyncServer is unsynchronized.
Reference: This field identifies the system peer. While stratum is 16, this field shows the progression of the NTP clock PLL. The field starts with a value of INIT. Once a peer has been selected, the clock might be stepped, in which case the reference ID field changes to STEP.
Once the PLL is locked, the stratum is updated and the reference ID provides information about the selected peer. When the SyncServer is operating at stratum 1, the reference ID displays the name of the Hardware Clock reference input.
NTP Packet I/O: It refers to the number of NTP packets the SyncServer has replied to and initiated. SyncServer replies to clients that send NTP requests. It also sends NTP requests when the NTP daemon is not synchronized (that is, Sync LED is RED) and when it is configured to synchronize to an NTP association (that is, a server type association).
Alarm Status Screen
The Alarm Status screen shows the current alarm status. To view details about the alarms, use the right or left arrow.

CLI Commands

4. CLI Commands
This section describes the CLI command conventions, the prompts, line editing functions, and command syntax. The CLI command functions and features are listed alphabetically.

4.1.

SyncServer S6x0 CLI Command Set
This section provides the list and details of all CLI commands. Both the serial CONSOLE CLI commands and SSH CLI commands should be identical.

4.1.1.

set clock
This command provides an ability to set the time. Command Syntax:

set clock date-time <date-time>

where <date-time> = YYYY-MM-DD,HH:MM:SS The time is presumed to be UTC.

4.1.2.

set configuration
Use this command to replace the current configuration with the factory default configuration. On SyncServer, the user is prompted with Y to confirm the step.
Command Syntax:

set configuration factory

Returning the configuration to factory default also causes the following: · Loss of configured user logins · Loss of configured network settings (addresses, firewall, and so on.) · Installed licenses remain installed · SyncServer S6x0 reboots as part of this process
The behavior with this command is identical to using the Web GUI to reset to factory default (Dashboard > Admin> Configuration Backup/Restore/Reset), see Figure 5-78.

4.1.3.

F9–Time on Request
The F9 command is used to record the time at which SyncServer S6x0 receives a request from the user. The following table lists the general behavior. This function is configurable through the CLI only. It is not configurable from the keypad.
Table 4-1. F9 Syntax Basic Behavior
Syntax Behavior F9<CR> Enables the connection for time on request operation. When enabled, the connection responds to Ctrl-C and
SHIFT-T inputs only. ctrl – C Disables the connection for time on request operation. SHIFT-T Enabling time on request triggers a time response on the connection.
Note:The T does not appear (it is not echoed back by SyncServer S6x0).

To record the time, perform the following: 1. Enter the F9<CR> command to prepare SyncServer S6x0 for the user’s request.

User Guide
© 2025 Microchip Technology Inc. and its subsidiaries

DS00003865G – 47

CLI Commands
2. At the desired moment, send the request to SyncServer S6x0 by entering an uppercase T. SyncServer S6x0 saves the current ToD, accurate to within 1 microsecond, to a buffer, and then outputs it to the CLI.
SyncServer S6x0 continues to provide the ToD each time it receives a T until F9 is cancelled.
To cancel F9, enter ctrl-C on your keyboard. The command line disregards all input other than SHIFT-T and Ctrl-C (hex 03).
The ToD output is only available on the network or serial port used to give the F9 command.
The format of the default string returned with SHIFT-T is entered (assuming time on request is enabled) is as follows:

<SOH>DDD:HH:MM:SS.mmmQ<CR><LF>

where:
· <SOH> = ASCII Start-of-Heading character · <CR> = ASCII Carriage Return character · <LF> = ASCII Line Feed character · YYYY = Year · DDD = Day-of-year · HH = Hours · MM = Minutes · SS= Seconds · mmm = Milliseconds · : = Colon separator · Q = Time quality character, as the following:
­ SPACE = Time error is less than time quality flag 1’s threshold ­ . = Time error has exceeded time quality flag 1’s threshold ­ * = Time error has exceeded time quality flag 2’s threshold ­ # = Time error has exceeded time quality flag 3’s threshold ­ ? = Time error has exceeded time quality flag 4’s threshold, or a reference source is
unavailable
Example:
· To prepare Time on Request, enter:
SyncServer> F9

· To request the current time, enter SHIFT-T on your keyboard. (T does not appear). Response:
<SOH>128:20:30:04.357*<CR><LF>

· To exit F9, press Ctrl-C on your keyboard.

The Clock Status indicator reports Locked when the SyncServer® S6x0 clock is locked to a reference source (for example, GPS, IRIG, and so on). This is the normal operational state of the clock. While locked, the clock steers its internal oscillator to the reference source. The Clock Status indicator reports Unlocked when the SyncServer S6x0 clock is not locked to a reference source. This might be because the reference source is unlocked or unstable. While unlocked from a reference source, the SyncServer S6x0 uses its internal oscillator to keep time until a reference becomes available again.

This section describes the Web interface for SyncServer S6x0. For details on how to access the Web interface, see Communicating Through LAN1 Ethernet Port. Note: · For security reasons, SyncServer S6x0 only supports HTTPS. However, the user gets warnings
from most web browsers that a self-signed certificate is being used (not from a recognized certificate authority). You must accept the warnings and proceed to the login page. The internal self-signed certificate can be renewed and updated on the Security > HTTPS page. You can also request and install an HTTPS certificate. The following figure shows the login page for the Web interface.

Notes: · The default username is admin and the default password is: Microsemi.
· To avoid unauthorized access, you must change the default password.
· When logging in for the first time, or after a factory default, the system forces you to change the password.
For security reasons, SyncServer S6x0 locks out a user for an hour if an invalid password is entered three times. The lockout is removed if the unit is rebooted. The lockout can be configured on the Admin > General page, see Figure 5-70.

Notes:
· UTC and local time are displayed in the upper right portion of the page. Local time is based on the timezone setting in the SyncServer unit. Daylight saving time is also applied to the local time if applicable. Local time is not determined by the location of the web browser.
· If the browser is displaying a busy indicator, then wait until the previous action is complete before starting another action. Depending on the browser used, the web page’s responsiveness varies due to the use of the encryption cipher suite used in S6x0. Microchip recommends using the Google Chrome browser. Under heavy network traffic load, the web responsiveness degrades.
· When system is under full-rated load, opening more than one web session is not recommended, as it has a large performance impact.

Note:SyncServer S6x0 does not contain a battery-backed real-time clock. Therefore, it always boots up with a default value for the system time. This time is updated when it obtains time from a time reference, such as GNSS, IRIG, or NTP. The default value for the date is the software build date. This date is used for the first log entries when booting up the unit. The time changes to local time during the boot-up process if a time zone is configured.

Web Interface

SyncServer S600/S650 has separate timing and frequency clock controls. The time and frequency clocks are usually in the same clock state. If they are different, then the Current Reference row includes text after the icon which displays the frequency clock state. The ToD status always shows the time clock state.
While locking to a new reference, the two states might be different for a brief time.
If there are no valid timing references, but there is a valid frequency reference, then there must be text shown, as the frequency and time clock states are different.
The system time locks but does not frequency lock to an NTP reference. Therefore, the frequency status displays free-run while the system is locked to an NTP reference and there are no frequency references connected.

SyncServer has selected a qualified active time input for use and is now in process of aligning all outputs to it.

In this status, the Current Source row, by definition, has a green item that has a match to it in the Timing Sources row. An active time source just means one that is continuously providing time (where continuous is a relative term–in general, it is an update per second).

Locked Bridging

SyncServer outputs are now aligned to a selected active time source.
SyncServer no longer has a selected active time source, but it has not been that way for very long.

—
This is really just the beginning of holdover but is a period where the output performance must be as good as when in Locked. It provides a hysteresis buffer to prevent nuisance Locked-Holdover-Locked transitions. In this state, the Current Source row does not have a green item from the Timing Sources row.

Holdover Holdover

SyncServer no longer has a selected active time source, and it has been that way for longer than the Bridging duration. Also, the condition for red holdover (next row) is not met.

Note:The main purpose of holdover is to allow the S6x0 time server to continue to operate as normal, using the internal oscillator or external frequency reference even though the connection to GNSS is lost. The user defines how long this holdover period will last. During this time, the NTP Reference Time Stamp is updated regularly indicating that S6x0 is still connected to a time reference. During holdover, the dispersion continually increases based on the clock model. If any configured NTP servers are reachable when the holdover period is exceeded, then the hardware clock will be marked as invalid to allow NTPd to switch reference to the remote server. Eventually, NTP will only use NTP servers and not the hardware clock.

When the status is any of these, there must be a selected time source, which takes precedence in the Current Reference row (more important than if there is also a qualified frequency reference). There must be at least one green item in the Timing References row. The leftmost green is identically indicated in the Current Reference row because the leftmost green item in Timing References is the highest priority time source and therefore must be selected. For example, if it is GNSS, it appears identically as Current Reference and in Timing References row.
For any Status in this category, there cannot be a qualified Timing Reference (nothing green in that row), so it is certain that SyncServer® is using frequency-only reference. If there is a qualified Frequency Reference (meaning something green in this row), then the leftmost green is the current source. If there is no qualified Frequency Reference (nothing green in that row), then only SyncServer internal reference remains, and it appears in the Current Reference row. In this case, the entry is one of the following, depending on the specific SyncServer product oscillator type:
· Internal Rb
· Internal OCXO
· Standard

5.1.2.2. GNSS Status and Information
The GNSS window in the dashboard, as shown in the following figure, displays status details and information about GNSS. C/No is the carrier-to-noise density which is defined as the carrier power divided by the noise power spectral density. Higher C/No results in better tracking and performance.
The GNSS signal strength (C/No) can vary from 1 to 63. Typical values for a good GNSS installation will be between 35 and 55. A satellite ID of “0?” might be temporarily displayed if the system is not fully tracking the satellite.

Notes: · Some SNMP browsers and trap managers require that an SNMPv3 user must be created with
the same username and authentication as used for the trap configuration, so that the SNMPv3 discovery process completes properly.
· SNMP is designed to be used with LAN1. Do not configure a SNMP manager address in a subnet used by the other LAN ports (LAN2­LAN6).
· Up to 10 SNMP trap recipients can be configured.
· Changing an SNMP configuration parameter (such as community or SNMPv3 user), causes SNMP to restart and the MIB2 sysuptime to restart counting upward.
5.2.1.4. Network–Ping
Use this window to perform network ping tests to test the network connectivity of the LAN ports as needed. The result of the ping is displayed in the window when completed. An IPv4 or IPv6 address must be entered in the IP address field.
Ping might not operate as expected when IPv6 auto-config is enabled. An IPv6 source address can be used that does not route correctly to the destination address.

Web Interface

At the bottom of the SysInfo page, a graph is included that shows the NTP packet load. It displays the number of packets sent per minute over the last 24 hours.

The restart button at the bottom of the page restarts NTPd. This also clears the statistics and the graph.

The following table lists the descriptions of the NTP Daemon Status and the Control parameters.

Table 5-6. NTPd SysInfo Parameter Descriptions

Parameter

Description

System Peer

The IP address of the clock source. The source is selected by the NTP daemon that is most likely to provide the best timing information based on: Stratum, distance, dispersion, and confidence interval. The address of the local SyncServer® Hardware Clock can be viewed in the hardware reference clock section of the NTP associations page.

Parameter

Description

System Peer mode

The relationship of SyncServer to a system peer, usually a client. Depending on the configuration, the mode can be:
· Client: A host operating in this mode sends periodic messages regardless of the reachability state or stratum of its peer. By operating in this mode, the host, usually a LAN workstation announces its willingness to be synchronized by, but not to synchronize the peer.

· Symmetric Active: A host operating in this mode sends periodic messages regardless of the reachability state or stratum of its peer. By operating in this mode, the host announces its willingness to synchronize and be synchronized by the peer.

· Symmetric Passive: This type of association is ordinarily created upon arrival of a message from a peer operating in the Symmetric Active mode and persists only if the peer is reachable and operating at a stratum level less than or equal to the host; otherwise, the association is dissolved. However, the association always persists until at least one message is sent in reply. By operating in this mode, the host announces its willingness to synchronize and be synchronized by the peer.
A host operating in Client mode (a workstation, for example) occasionally sends an NTP message to a host operating in Server mode (SyncServer), perhaps right after rebooting and at periodic intervals thereafter. The server responds by simply interchanging addresses and ports, filling in the required time information and returning the message to the client. Servers must retain no state information between client requests, while clients are free to manage the intervals between sending NTP messages to suit local conditions.
In the symmetric modes, the client/server distinction (almost) disappears. Symmetric Passive mode is used by time servers operating near the root nodes (lowest stratum) of the synchronization subnet and with a relatively large number of peers on an intermittent basis. In this mode, the identity of the peer need not be known in advance, as the association with its state variables is created only when an NTP message arrives. Also, the state storage can be reused when the peer becomes unreachable or is operating at a higher stratum level and thus ineligible as a synchronization source.
Symmetric Active mode can be used by time servers operating near the end nodes (highest stratum) of the synchronization subnet. Reliable time service can usually be maintained with two peers at the next lower stratum level and one peer at the same stratum level, so the rate of ongoing polls is usually not significant, even when connectivity is lost, and error messages are being returned for every poll.

Leap Indicator

The Leap Indicator (LI) is a two-bit binary number in the NTP packet header that provides the following information:
· Warning: A leap second adjustment will be made to the UTC timescale at the end of the current day. Leap seconds are events mandated by the world time authority (BIPM) to synchronize the UTC time scale with the earth’s rotation.
· Whether the NTP daemon is synchronized to a timing reference. LI Meaning:
­ 00: No Warning
­ 01 Leap second insertion: Last minute of the day has 61 seconds
­ 10 Leap second deletion: Last minute of the day has 59 seconds
­ 11: Alarm condition (not synchronized)
When SyncServer or NTP daemon is started or restarted, the leap indicator is set to “11”, the alarm condition. This alarm condition makes it possible for NTP clients to recognize that an NTP server (SyncServer) is present, but that it has yet to validate its time from its time sources. Once SyncServer finds a valid source of time and sets its clock, it sets the leap indicator to an appropriate value. The NTP Leap Change Alarm on the ADMIN-Alarms page can be configured to generate an alarm and send notifications each time the leap indicator changes state.

Table 5-6. NTPd SysInfo Parameter Descriptions (continued)

Parameter

Description

Stratum

This is an eight-bit integer that indicates the position of an NTP node within an NTP timing hierarchy. It is calculated by adding 1 to the stratum of the NTP system peer. For SyncServer, the stratum values are defined as follows: Stratum Meaning:
· 0: Hardware Clock when locked

· 1: Primary server

· 2­15: Secondary server

· 16­255: Unsynchronized, unreachable

For example, SyncServer is:
· Stratum 1: When the Hardware Clock (stratum 0) is synchronized to an input reference, in Holdover mode, or in Freerun mode

· Stratum 2 through 15: When it is synchronized to a remote NTP server

· Stratum 16: When it is not synchronized, indicating that it is searching for a valid source of timing information
