Installing An Hvac/Hvdc Power Supply - Cisco Nexus 9372PX Hardware Installation Manual

Replacing Components
Step 3
Grasp the power supply handle while pressing the release latch towards the power supply handle.
Step 4 Pull the power supply out of the bay.
Step 5 If you cannot replace the power supply, fill the empty slot with a blank module (part number N2200-P-BLNK). Otherwise,
you are ready to install a power supply in the open slot.

Installing an HVAC/HVDC Power Supply

This topic is for installing the high-voltage AC/DC (HVAC/HVDC) power supply into a switch chassis.
If the switch has two power supplies, you can replace one power supply while the other one provides power
to the switch. If you have only one power supply in the switch, install the replacement power supply in the
open slot, power up the replacement power supply, and then remove the original power supply.
Before You Begin
• If you are using DC power for the replacement power supply, the circuit breaker for the DC power source
• The power source for the replacement power supply must be within reach of the power supply power
• If you are using n+n power redundancy, there must be a separate power source for each power supply
• There must be an earth ground connection to the chassis that you are installing the replacement module.
Step 1 If the power supply slot has a blank filler panel, remove it from the slot by moving its release latch to the left and pulling
the panel out of the slot.
Step 2
Holding the replacement power supply with one hand underneath the module and the other hand holding the handle,
align the back end of the power supply (the end with the electrical connections) to the open power supply slot and slide
the power supply all the way into the slot until it clicks into place.
Step 3
If the DC power cables and a grounding cable are already connected to an electrical connector block, insert the block
into the power receptacle on the power supply.
If the electrical cables have not been connected to the electrical connector block, wire them as described in
V DC Electrical Connector Block, on page
Step 4 Turn on the circuit breaker for the DC power source connected to the power supply.
Step 5
Verify that the power supply
must be turned off.

installed in the chassis. Otherwise, only one power source is required.
