Preliminary Information

Overview
The American Power Conversion (APC®) Rack Automatic Transfer Switch (ATS) is a high-availability switch that provides redundant power to connected equipment and has two input power cords, one for each AC line. The Rack ATS supplies power to the connected load from a primary AC source. If that primary source becomes unavailable, the Rack ATS automatically begins sourcing power from the secondary source. The transfer time from one source to the other is seamless to the connected equipment, as the switching occurs safely between the two input sources regardless of any phase differences. The units have built-in network connectivity, which allows for remote management through the Web, SNMP, or Telnet interfaces.

Installation

Mounting options
Horizontal mounting. You can mount the Rack ATS in a APC NetShelter® or other EIA-310-D standard 19-in rack:

1. Choose a mounting position for the Rack ATS with either the digital display or the rear panel facing out of the enclosure.
2. Attach the mounting brackets to the Rack ATS using the provided flat-head screws.
3. Choose a location for the unit:
   Note: The unit occupies one or two U-spaces. A notched hole (or a number, on newer enclosures) on the enclosures vertical rail indicates the middle of a U-space.
   • Insert cage nuts above and below a notched hole on each vertical mounting rail in your chosen location.
   • Align the mounting holes of the brackets with the installed cage nuts. Insert and tighten screws.
     

Recessed horizontal mounting. You can mount the Rack ATS in a recessed configuration by attaching the brackets as shown in the following illustration of the Rack ATS.

Quick Configuration

Note: Disregard the procedures in this section if you have APC InfraStruXure® Central or InfraStruXure Manager as part of your system. See the InfraStruXure devices documentation for more information.

Overview

You must configure the following TCP/IP settings before the Rack ATS can operate on a network:

• IP address of the Rack ATS
• Subnet mask
• Default gateway
  • Note: If a default gateway is unavailable, use the IP address of a computer that is located on the same subnet as the Rack ATS and that is usually running. The Rack ATS uses the default gateway to test the network when traffic is very light.
  • Caution: Do not use the loopback address (127.0.0.1) as the default gateway address. It disables the network connection of the Rack ATS and requires you to reset TCP/IP settings to their defaults using a local serial login.
  • See Watchdog Features in the Introduction of the Users Guide for more information about the watchdog role of the default gateway.

TCP/IP Configuration Methods

Use one of the following methods to define the TCP/IP settings:

• APC Device IP Configuration Wizard (See Device IP Configuration Wizard on this )
• BOOTP or DHCP server (See BOOTP & DHCP configuration.)
• Local computer (See Local access to the control console.)
• Networked computer (See Remote access to the control console.)

Device IP Configuration Wizard

You can use the APC Device IP Configuration Wizard at a computer running Microsoft® Windows® 2000, Windows 2003, or Windows XP to configure the basic TCP/IP settings of a Rack ATS.

To configure one or more Rack ATSs by exporting configuration settings from a configured Rack ATS, see How to Export Configuration Settings in the Users Guide on the Utility CD.

Note: Most software firewalls must be temporarily disabled for the Wizard to discover unconfigured Rack ATSs.

1. Insert the APC Automatic Transfer Switch Utility CD into a computer on your network.
2. If autorun is enabled, the user interface of the CD starts when you insert the CD. Otherwise, open the file contents.htm on the CD.
3. Click Device IP Configuration Wizard and follow the instructions.

Note: If you leave the Start a Web browser when finished option enabled, you can use apc for both the user name and password to access the Rack ATS through your browser.

BOOTP & DHCP configuration

• The TCP/IP option in the Network menu, under the Administration tab of the Web interface, identifies how TCP/IP settings will be defined. The possible settings are Manual, BOOTP, DHCP, and DHCP & BOOTP (the default setting).
• The DHCP & BOOTP setting assumes that a properly configured DHCP or BOOTP server is available to provide TCP/IP settings to the Rack ATS. The Rack ATS first attempts to discover a properly configured BOOTP server, and then a DHCP server. It repeats this pattern until it discovers a BOOTP or DHCP server.
• If these servers are unavailable, see Device IP Configuration Wizard, Local access to the control console, or Remote access to the control consoleto configure the TCP/IP settings.
• BOOTP. For the Rack ATS to use a BOOTP server to configure its TCP/IP settings, it must find a properly configured RFC951-compliant BOOTP server.
• If a BOOTP server is unavailable, see Device IP Configuration Wizard, Local access to the control console, or Remote access to the control consoleto configure TCP/IP settings.

1. In the BOOTPTAB file of the BOOTP server, enter the MAC address, IP address, subnet mask, default gateway, and optionally, a bootup file name of the Rack ATS.
   Note: The MAC address can be found in the About ATS menu of the control console or web interface and also on the Quality Assurance slip included in the package.
2. When the Rack ATS reboots, the BOOTP server provides it with the TCP/IP settings.
   If you specified a bootup file name, the Rack ATS attempts to transfer that file from the BOOTP server using TFTP or FTP. The Rack ATS assumes all settings specified in the bootup file.
   If you did not specify a bootup file name, you can configure the other settings of the Rack ATS remotely through its Web interface or control console; user name and password are both apc by default.
   See Remote access to the control consolefor configuration instructions.
   To create a bootup file, see your BOOTP server documentation.

DHCP. You can use an RFC2131/RFC2132-compliant DHCP server to configure the TCP/IP settings for the Rack ATS.

This section summarizes the Rack ATS communication with a DHCP server. For more detail about how a DHCP server is used to configure the network settings for the Rack ATS, see DHCP Configuration in the Users Guide.

1. The Rack ATS sends a DHCP request that uses the following to identify itself:
   • Vendor Class Identifier (APC by default)
   • Client Identifier (by default, the MAC address of the Rack ATS)
   • User Class Identifier (by default, the identification of the application firmware used by the Rack ATS)
2. A properly configured DHCP server responds with a DHCP offer that includes all of the settings that the Rack ATS needs for network communication. The DHCP offer also includes the Vendor Specific Information option (DHCP option 43). By default, the Rack ATS ignores DHCP offers that do not encapsulate the APC cookie in the Vendor Specific Information option using the following hexidecimal format:Option 43 = 01 04 31 41 50 43

   where

   • The first byte (01) is the code
   • The second byte (04) is the length
   • The remaining bytes (31 41 50 43) are the APC cookie
     See your DHCP server documentation to add code to the Vendor Specific Information option.
     To disable the requirement that a DHCP offer include the APC cookie, use the DHCP Cookie Is setting in the control console: Network>TCP/IP>Boot Mode>DHCP only>Advanced>DHCP Cookie Is. To access the control console, see Remote access to the control console.

Local access to the control console
You can use a local computer to connect to the ATS to access the control console.

1. Select a serial port at the local computer and disable any service that uses that port.
2. Use the communication cable to connect the selected port to the serial port on the front panel of the ATS.
3. Run a terminal program (such as HyperTerminal®) and configure the selected port for 9600 bps, 8 data bits, no parity, 1 stop bit, and no flow control. Save the changes.
4. Press ENTER to display the User Name prompt.
5. Use apc for the username and password.
6. See Control consoleto finish the configuration.

Remote access to the control console
From any computer on the same network as the Rack ATS, you can use ARP and Ping to assign an IP address to the Rack ATS and then use Telnet to access the control console of that Rack ATS and configure the other TCP/IP settings.

Note: After the IP address of the Rack ATS is configured, you can use Telnet, without first using ARP and Ping, to access that Rack ATS.

1. Use ARP to define an IP address for the Rack ATS and use the MAC address of the Rack ATS in the ARP command. For example, to define an IP address of 156.205.14.141 for a Rack ATS that has a MAC address of 00 c0 b7 63 9f 67, use one of the following commands:
   1. Windows command format:
      arp -s 156.205.14.141 00-c0-b7-63-9f-67
   2. LINUX command format:
      arp -s 156.205.14.141 00:c0:b7:63:9f:67
      Note: The MAC address can be found in the About ATS menu of the control console or Web interface and also on the Quality Assurance slip included in the package.
2. Use Ping with a size of 113 bytes to assign the IP address defined by the ARP command. For example:
   1. Windows command format:
      ping 156.205.14.141 -l 113
   2.  LINUX command format:
      ping 156.205.14.141 -s 113
3. Use Telnet to access the Rack ATS at its newly assigned IP address. For example:
   telnet 156.205.14.141
4. Use apc for both username and password.
5. See Control console to finish the configuration.

Control console

After you log on at the control console, as described in Local access to the control console or Remote access to the control console:

1. Choose Network from the Control Console menu.
2. Choose TCP/IP from the Network menu.
3. If you are not using a BOOTP or DHCP server to configure the TCP/IP settings, select the Boot
   Mode menu. Select Manual boot mode, and then press ESC to return to the TCP/IP menu.
   (Changes will take effect when you log out).
4. Set the System IP, Subnet Mask, and Default Gateway address values.
5. Press CTRL+C to exit to the Control Console menu.
6. Log out (option 4 in the Control Console menu).
   Note: If you disconnected a cable during the procedure described in Local access to the control console, reconnect that cable and restart the associated service.

How to Access the Rack ATS Interfaces

Overview
After the Rack ATS is running on your network, you can use the interfaces summarized here to access the unit.
For more information on the interfaces, see the Users Guide.

Web interface

Use Microsoft Internet Explorer (IE) 5.5 or higher (on Windows operating systems only), Firefox, version 1.x, by Mozilla Corporation (on all operating systems), or Netscape® 7.x or higher (on all operating systems) to access the Rack ATS through its Web interface. Other commonly available browsers also may work but have not been fully tested by APC. To use the Web browser to configure Rack ATS options or to view the event and data logs, you can use either of the following protocols:

The HTTP protocol (enabled by default), which provides authentication by user name and password but no encryption.
The more secure HTTPS protocol, which provides extra security through Secure Sockets Layer (SSL) and encrypts user names, passwords, and data being transmitted. It also provides
authentication of Rack ATSs by means of digital certificates.

To access the Web interface and configure the security of your unit on the network:

1. Access the Rack ATS by its IP address (or DNS name if configured).
2. Enter the user name and password (by default, apc and apc for an Administrator).
3. Select and configure the type of security you want by selecting the Administration tab, and then the Security menu from the top menu bar (This option is available only for Administrators).
   See the Security Handbook, available on the Utility CD or from the APC Web site, www.apc.com, for more information on selecting and configuring network security.

Telnet and SSH
You can access the control console through Telnet or Secure SHell (SSH), depending on which is enabled. (An Administrator can enable these access methods through the Telnet/SSH option of the Network menu). By default, Telnet is enabled. Enabling SSH automatically disables Telnet.

Telnet for basic access. Telnet provides the basic security of authentication by user name and password, but not the high-security benefits of encryption. To use Telnet to access the Rack ATS control console from any computer on the same network:

1. At a command prompt, use the following command line, and press ENTER: telnet address
   Note: As address, use the Rack ATS IP address (or DNS name if configured).
2. Enter the user name and password (by default, apc and apc for an Administrator, or device and apc for a Device User).
   SSH for high-security access. If you use the high security of SSL for the Web interface, use Secure SHell (SSH) to access the control console. SSH encrypts user names, passwords, and transmitted data.
   The interface, user accounts, and user access rights are the same whether you access the control console through SSH or Telnet, but to use SSH, you must first configure SSH and have an SSH client program installed on your computer.
   See the Users Guide for more information on configuring and using SSH.

SNMP

• SNMPv1 only. After you add the PowerNet® MIB to a standard SNMP MIB browser, you can use that browser for SNMP access to the Rack ATS. The default read community name is public; the default read/write community name is private.
• SNMPv3. For SNMP GETs, SETs, and the trap receivers, SNMPv3 uses a system of user profiles to identify users. An SNMPv3 user must have a user profile assigned in the MIB software program to perform GETs and SETs, browse the MIB, and receive traps. The default settings are no authentication and no privacy.

Note: To use SNMPv3, you must have a MIB program that supports SNMPv3. The Rack ATS supports only MD5 authentication and DES encryption.

• SNMPv1 and SNMPv3. To use InfraStruXure Central or InfraStruXure Manager to manage the Rack ATS on the public network of an InfraStruXure system, you must have SNMPv1 enabled in the unit interface. Read access allows InfraStruXure devices to receive traps from the Rack ATS. Write access is required while you set the InfraStruXure device as a trap receiver.
• All user names, passwords, and community names for SNMPv1 are transferred over the network as plain text. If your network requires the high security of encryption, disable SNMPv1 access and use SNMPv3 instead.
• To enable or disable SNMP access, you must be an Administrator. Select the Administration tab, select the Network menu on the top menu bar, and use the access option under SNMPv1 or SNMPv3 on the left navigation menu.

FTP and SCP

You can use FTP (enabled by default) or Secure CoPy (SCP) to transfer downloaded firmware to the ATS, or to access a copy of the event or data logs of the ATS.
To use an InfraStruXure Central or InfraStruXure Manager to manage the ATS, you must have FTP Server enabled in the ATS interface.
To enable or disable FTP Server access, you must be an Administrator. Select the Administration tab, select the Network menu on the top menu bar, and use the FTP Server option on the left navigation menu.

In the Rack ATS Users Guide, see the following sections:

• To transfer firmware, see File Transfers.
• To retrieve a copy of the event or data log, see How to use FTP or SCP to retrieve log files.

Managing the security of your system
For detailed information on enhancing the security of your system after installation and initial configuration, see the Security Handbook, available on the Utility CD and on the APC Web site, www.apc.com.

Configuring the Rack ATS

Configuring sensitivity
The sensitivity setting controls how tolerant the Rack ATS is of fluctuations in power before it switches to the secondary power source. Configure the sensitivity range for your Rack ATS using the Switch Configuration menu, which can be found by selecting the Unit tab and the Configuration menu in the left navigation menu. When sensitivity is set to Low, the Rack ATS waits 4 ms before switching to the alternate power source when there is a disturbance in the power supply. When sensitivity is set to High, the Rack ATS waits 2 ms before transferring power. The default setting is High.

Configuring voltage transfer range
The voltage transfer range determines the acceptable RMS voltages for the Rack ATS. When voltage moves outside the specified range, the Rack ATS switches to the secondary power source. Configure the voltage transfer range using the Switch Configuration menu. The Rack ATS can be set to Narrow, Medium, or Wide voltage ranges, depending on the power conditions of your system.

Note: The default setting of the voltage range is Medium.
