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