(TOR), Middle-of-Rack (MoR), and End-of-Rack (EoR) deployment in data centers. This switch has 96 fixed
1/10GBASE-T (copper) downlink ports and six fixed 40-Gigabit QSFP+ (optical) uplink ports. The chassis
for this switch includes the following user-replaceable components:
• Fan modules (two) with the following airflow choices:
• Power supply modules (two—one for operations and one for redundancy [1+1]) with the following

◦ Port-side exhaust airflow with blue coloring (N9K-C9300-FAN3-B)
◦ Port-side intake airflow with burgundy coloring (N9K-C9300-FAN3)
choices:
◦ 1200-W HVAC/HVDC dual-directional airflow power supply with white coloring
(N9K-PUV-1200W)
◦ 1200W port-side exhaust AC power supply with blue coloring (N9K-PAC-1200W-B)
◦ 1200W port-side intake AC power supply with burgundy coloring (N9K-PAC-1200W)
◦ 930W port-side intake DC power supply with green coloring (UCSC-PSU-930WDC)
◦ 930W port-side exhaust DC power supply with gray coloring (UCS-PSU-6332-DC)
You can use the different types of power supplies interchangeably so long as they have
Note
the same direction of airflow (if DC power supplies are used, all of the fan and power
supply modules must have port-side intake airflow). If you are using the 1200-W
HVAC/HVDC power supply, the power supply automatically uses the same airflow
direction as used by the fan modules installed in the same switch.
