Removing A Dc Power Supply - Cisco Nexus 9332PQ Hardware Installation Manual

Removing a DC Power Supply

the power supply in a chassis that has only one power supply, install the new power supply in the open power
supply slot and power it up before removing the older power supply.
Step 1 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.
If you need to remove an Anderson's Saf-D-Grid power cable connector from a high-voltage power supply,
Note
press the tab at the top of the connector and pull the connector out of the power supply.
Step 2 Release the power supply from the chassis by moving the power supply release latch to the left and then pulling the
power supply part way out of the chassis.
Step 3 Place your other hand under the power supply to support it while you slide it out of the chassis.
Do not touch the electrical connectors on the back side of the module and prevent anything else from coming
Caution
into contact with and damaging the connectors.
Step 4
If the power supply slot in the chassis is to remain empty, install a blank power supply filler panel (part number
N2200-P-BLNK). Otherwise, install another power supply in the slot as explained in
on page 36.
Warning Statement 1029—Blank Faceplates and Cover Panels
Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous
voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt
other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless
all cards, faceplates, front covers, and rear covers are in place.
Removing a DC Power Supply
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 before removing the original power supply.
To disconnect the power supply from its power cables, you must shut off the power from the power source
and then either disconnect a connector for the power cables or release each of three cables from the power
supply (requires a standard screw driver).
Step 1
Turn off the circuit breaker for the power source to only the power supply that you are replacing (be sure that this does
not turn off power to the other power supply that is powering the switch during this replacement process).
Be sure that the LEDs turn off on the power supply that you are removing.
Step 2 Remove the power cable from the power supply by doing the following:
• If you need to remove an orange power cable connector from a 48-V DC power supply, do the following:
1 Push the orange plastic button on the top of the connector block inward toward the power supply.
2 Pull the connector block out of the power supply.
• If you need to remove an Anderson Power Products Saf-D-Grid power cable connector from a high-voltage power
supply, press on the tab at the top of the Saf-D-Grid connector and pull the connector out of the power supply.
