The Cisco Nexus 92348GC-FX3 switch (N9K-C92348GC-FX3) is a 1-RU fixed-port, L2/L3 switch, designed for deployment in data centers. This switch has 48x 10M/100M/1G BASE-T downlink ports, 4x 10/25 Gbps SFP28+ uplink ports, 2x 40/100 Gbps QSFP28+ uplink ports, and will deliver 696 Gbps of total bandwidth.

This switch includes these user-replaceable components:

• Three fan modules with these airflow choices:

• Port-side intake airflow with burgundy coloring (NXA-SFAN-30CFM-PI)

• Port-side exhaust airflow with blue coloring (NXA-SFAN-30CFM-PE)

Note	This switch will power down due to a fan-policy trigger if fewer than 2 fans are operational.

Note	Table 1. Fan Speeds for this Switch Port-Side Intake Fan Speed % Port-Side Exhaust Fan Speed % Typical/Minimum 40% 40% Maximum 100% 100%

Note	Each fan module has two rotors. The switch can function normally if one rotor inside the any one fan module fails. In case of more than one rotor failure, the switch will issue a warning and power down in 2 minute.

Note	This switch supports a mix of AC and DC power supplies in the same chassis for up to 15 minutes. This enables you to switch from AC/DC (and vise versa) without the interruption of a power cycle.

• Power supply modules (two—one for operations and one for redundancy [1+1]) with these choices (a mix of AC and DC power sources is supported. However, do not mix airflow directions):

  • 350-W AC power supply with port-side intake airflow (burgundy coloring) (NXA-PAC-350W-PI2)

  • 350-W AC power supply with port-side exhaust airflow (blue coloring) (NXA-PAC-350W-PE2)

  • 350-W PHV power supply with port-side intake airflow (burgundy coloring) (NXA-PHV-350W-PI)

  • 350-W PHV power supply with port-side exhaust airflow (blue coloring) (NXA-PHV-350W-PE)

  • 440-W DC power supply with port-side intake airflow (burgundy coloring) (NXA-PDC-440W-PI)

  • 440-W DC power supply with port-side exhaust airflow (blue coloring) (NXA-PDC-440W-PE)

• Note	The 350-W AC power supply does not have the standby voltage to be able to carry to a second power supply, to allow it to communicate and poll the device.

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

Caution

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