Important Notes and Cautions

[Warning] For a safe and reliable installation, use only the accessories and screws provided with the AS7326-56X. Use of other accessories and screws could result in damage to the unit. Any damages incurred by using unapproved accessories are not covered by the warranty.

[Caution] The device must be installed in a restricted-access location.

[Caution] The switch includes plug-in power supply (PSU) and fan tray modules that are installed into its chassis. All installed modules must have a matching airflow direction. That is, if the installed power modules have a front-to-back (F2B) airflow direction, all the installed fan tray modules must also have a F2B airflow direction.

[Note] The switch has the Open Network Install Environment (ONIE) software installer pre-loaded on the switch, but no switch software image. Information about compatible switch software can be found at www.edge-core.com.

Installation Steps

1. Attach the Brackets

Diagram shows attaching the front- and rear-post brackets to the switch using four of the included bracket screws.

Use the screws and cage/clip nuts supplied with the rack to secure the switch in the rack.

2. Adjust Rear-Post Bracket Ears

Diagram shows locking the position of the rear-post bracket ears using the included position-locking screws. The rear-post bracket ears can be adjusted to fit different rack depths from 56 cm to 75 cm.

3. Ground the Switch

Diagram shows the rear of the switch and a grounding point. Ensure the rack is properly grounded and in compliance with ETSI ETS 300 253. Verify that there is a good electrical connection to the grounding point on the rack (no paint or isolating surface treatment).

Diagram shows connecting the ground wire (#14 AWG) to the switch rear panel grounding point and then connecting the other end of the wire to rack ground.

[Caution] The earth connection must not be removed unless all supply connections have been disconnected.

Connect Power

1. Install PSUs

Install one or two AC or DC PSUs in the switch. The switch supports up to two PSUs that must have the same matching airflow direction as the installed fan trays.

2. Connect Power Source

Diagram shows connecting an external AC or DC power source to the PSUs. A close-up shows a Positronic PLA03F7000/AA connector with DC Return, -36 to -72 VDC, and Ground connections.

[Caution] Use a UL/IEC/EN 60950-1 certified power supply to connect to a DC converter, and a #14 AWG (for -36 VDC to -72 VDC PSU) wire to connect to a DC PSU.

Verify Switch Operation

1. Check System LEDs

Diagram shows the front panel of the switch with system LEDs. Verify basic switch operation by checking the system LEDs. When operating normally, the PSU1/PSU2 and Fan LEDs should all be green.

Perform Initial System Boot

1. Network Connection

If the network operating system (NOS) installer is located on a network server, first connect the RJ-45 Management (Mgmt) port to the network using 100-ohm Category 5, 5e or better twisted-pair cable. (Not required if the NOS installer is located on attached storage.)

2. Boot the Switch

Boot the switch. Wait for the ONIE software to locate and execute the NOS installer, and then wait for the installer to load the NOS software image. Subsequent switch boots will bypass ONIE and directly run the NOS software.

[Note] Refer to the network operating system (NOS) installer and NOS documentation for details on software options and set up for ONIE.

Connect Network Cables

1. Management Port

For the RJ-45 Management port, connect a 100-ohm Category 5, 5e or better twisted-pair cable.

2. Data Ports (SFP28/QSFP28)

Connect DAC cables to the SFP28/QSFP28 slots. Or first install SFP28/QSFP28 transceivers in the slots and then connect fiber optic cabling to the transceiver ports.

As connections are made, check the port status LEDs to be sure the links are valid.

For the SFP28 ports:

• Green: 25 Gbps mode
• Yellow: 10 Gbps mode

Each QSFP28 port has four LEDs that indicate valid links in the following modes:

• 1 LED Green: 100 Gbps mode
• 1 LED Blue: 40 Gbps mode
• 1-4 LEDs Yellow: 25 Gbps breakout mode (four lanes)
• 1-4 LEDs Purple: 10 Gbps breakout mode (four lanes)
