Replacing a Power Supply Module

The switch requires two power supplies for redundancy. With one power supply providing the necessary
power for operations, you can replace the other power supply during operations so long as the new power
supply has the same airflow direction as the other modules in the chassis.
You can replace a power supply with another supported power supply that has the same power source type
(AC, DC, HVAC, or HVDC) and the same wattage rating as the other installed power supply. Additionally,
the airflow direction of the power supply must match the airflow direction of the installed fan modules. For
the airflow direction used by the switch, see the coloring of the fan modules. The following list describes the
power supplies supported by this switch.
• NXA-PAC-1100W-PE2 (1100-W, port-side exhaust (blue latch) power supply requiring AC power
• NXA-PAC-1100W-PI2 (1100-W, port-side intake (burgundy latch) power supply requiring AC power
• N9K-PHV-1100W-PE (1100-W, port-side exhaust (blue latch) high-voltage AC/DC power supply
• N9K-PHV-1100W-PI (1100-W, port-side intake (burgundy latch) high-voltage AC/DC power supply
• NXA-PDC-1100W-PE (1100-W, port-side exhaust (blue latch) power supply requiring DC power source
• NXA-PDC-1100W-PI (1100-W, port-side intake (burgundy latch) power supply requiring DC power

Replacing an AC Power Supply

You can replace an AC power supply during operations so long as the other power supply provides to the
switch.
Before you begin
• The replacement power supply must have the same wattage and airflow direction as the power supply
• An AC power source must be within reach of the power cable that will be used with the replacement

Note
You can determine the airflow direction by looking at the coloring of the latch
on each power supply. AC power supplies with burgundy latches have port-side
intake airflow direction, and power supplies with blue latches have port-side
exhaust airflow direction.
power supply. If you are using n+n power redundancy, there must be a separate power source for each
power supply installed in the chassis.
