Overview

Overview
The Cisco Nexus 9332D-GX2B switch (N9K-C9332D-GX2B) is a 1-rack unit (RU), fixed-port switch designed
for spine-leaf-APIC deployment in data centers.
This switch includes the following ports:
• 400-Gigabit QSFP-DD ports (32)
• 10-Gigabit SFP+ ports (2)
• Management ports (one 10/100/1000BASE-T port and one SFP port)
• Console port (RS-232)
• USB port
• If MACsec is enabled on 8 ports, then you can not use high powered (>12W) optics.
• If MACsec is enabled on 4 ports, then you can use 4 ports with high powered (>12W) optics.
• If no MACsec is enabled, then you can use 8 ports with high powered (>12W) optics.
Note
Default port-profile information for this switch:
• Default port profile (Leaf): 24 downlinks and 8 fabric links + 2x1/10G downlinks
Leaf/Spine role considerations:
• This switch's default role is as a leaf switch.
• The default fabric links (ports 25-32) must be used for initial switch discovery via another switch.
•To change the switch from the default role, you must proceed as follows: the node appears as a discovered
device in the fabric inventory view, you must set the role of the switch (spine or leaf) and the switch
automatically goes for reboot to come up in the configured role.

• If you connect a default spine (i.e. a dual role switch that by default is a spine, such as Nexus 9316D-GX)
directly to an APIC, the change of the role to leaf is performed automatically by APIC as well as the
reboot. After that, the node appears in “Nodes pending registration” and you need to register the node.
Discovery considerations:
• Discovery via APIC – use the default downlink ports.
• Spine discovery – use the default fabric links (ports 25-32) and convert the switch to spine (reboot is
required).
• Leaf discovery via spine – use the default fabric links (ports 25-32).
• Sub leaf discovery via leaf – use the default fabric links (ports 25-32).
• Multipod (Pod 2+) first spine discovery via IPN – Connect the IPN to one of the default fabric links
(ports 25-32). Ensure the spine has at least one leaf node connected to it.
This switch includes the following user-replaceable components:
• Fan modules (6) with the following airflow choices:
• Port-side intake fan module with burgundy coloring (NXA-SFAN-35CFM-PI)
• Power supply modules (two—One for operations and one for redundancy [1+1]) with the following
choices:
• 1500-W port-side intake AC power supply with blue coloring (NXA-PAC-1500W-PI)
• 1100-W port-side intake DC power supply with burgundy coloring (NXA-PDC-1100W-PI)
• All fan modules and power supplies must use the same airflow direction.
• 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.

Modules Compatibility Information document.

The fan and power supply modules are field replaceable. You can replace one fan module or one power supply
module during operations so 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.
All fan and power supply modules must have the same direction of airflow. Otherwise, the switch can overheat
and shut down.
Note
If the switch has port-side intake airflow (burgundy coloring for fan modules), you must locate the ports in
the cold aisle. If the switch has port-side exhaust airflow (blue coloring for fan modules), you must locate the
ports in the hot aisle. If you locate the air intake in a hot aisle, the switch can overheat and shut down.
