Overview

Overview

The Cisco Nexus 9348D-GX2A switch (N9K-C9348D-GX2A) is a 2-rack unit (RU), fixed-port switch designed for deployment in data centers.

This switch includes the following ports:

  • 400-Gigabit QSFP-DD ports (48)

  • 10-Gigabit SFP+ ports (2)

  • Management ports (one RJ-45 port and one SFP port)

  • Console port

  • USB port


Note

Use dust covers (NXA-ACC-QDD-DC) for unused ports. It protects the connectors and helps divert airflow for thermal dispensation.

This switch includes the following user-replaceable components:

  • Fan modules (four) with the following airflow choices:

    • Port-side intake fan module with burgundy coloring (NXA-FAN-160CFM2-PI)


      Note

      If a fan fails, the other fans are automatically increased to 100% capacity to compensate. If two fans fail, then multi-fan failure policy kicks in, the switch will issue a warning, and power down in 2 minutes.

  • Power supply modules (two—One for operations and one for redundancy [1+1]) with the following choices:

    • 3200-W port-side intake AC/HVDC power supply with burgundy coloring (NXA-PAC-3200W-PI)

    • 3200-W port-side intake DC/HVDC power supply with burgundy coloring (NXA-PDC-3200W-PI)


    Note

    Both power supplies are the same type. Do not mix AC and DC power supplies.

    All fan modules and power supplies must use the same airflow direction.

The following figure shows the switch features on the port side of the chassis.

Grounding pad

The fan and power supply modules are field replaceable. You can replace one fan module or one power supply module during operations, as long as the other modules are installed and operating. If you have only one power supply installed, you can install the replacement power supply in the open slot before removing the original power supply.


Note

All fan and power supply modules must have the same direction of airflow, or the switch can overheat and shut down. If you are installing a dual-direction power supply, that module automatically uses the same airflow direction as the other modules in the switch.


Caution

If the switch has port-side intake airflow (burgundy coloring for fan modules), you must locate the ports in the cold aisle. If you locate the air intake in a hot aisle, the switch can overheat and shut down.

Use dust covers (NXA-ACC-QDD-DC) for unused ports. This protects the connectors and helps divert airflow for thermal dispensation.
