Replacing An Ac Power Supply - Cisco Nexus 9348GC-FXP NX-OS Hardware Installation Manual

Replacing Components
You can replace a power supply with another supported power supply that has the same power source type
(AC) 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.
• N9K-PAC-350W-PE (350-W, port-side exhaust (blue latch) power supply)
• N9K-PAC-350W-PI (350-W, port-side intake (burgundy latch) power supply)

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
• There must be an earth ground connection to the chassis that you are installing the replacement module.
Step 1 Remove an AC power supply as follows:
a) Holding the plug for the power cable, pull the plug out from the power receptacle on the power supply and verify
that both power supply LEDs are off.
b) Grasp the power supply handle while pressing the colored release latch towards the power supply handle.
c) Place your other hand under the power supply to support it while you slide it out of the chassis.
Do not touch the electrical connections on the back side of the module and prevent anything else from

coming into contact with and damaging the connectors.
Step 2 Install the replacement power supply as follows:
a) Holding the replacement power supply with one hand underneath the module and the other hand holding the handle,
turn the power supply so that its release latch is on the right side and align the back end of the power supply (the end
with the electrical connections) to the open power supply slot before carefully sliding the power supply all the way
into the slot until it clicks into place.
If the power supply does not fit into the open slot, turn the module over before sliding it carefully into the

being replaced. Do not mix AC, DC, HVAC/HVDC power supplies in the same switch.
You can determine the airflow direction by looking at the coloring of the latch on each

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.
AC power supplies connected to AC power sources are automatically grounded through their power
cable.
