Cisco Nexus 9508 - Installing or Replacing a 3-Kw Universal AC;DC Power Supply

•
If you are using the n+n redundancy mode, you must connect the power cable to the same power source as used
by the other power supplies in the same set of power supply slots in the chassis. The power cables for slots 1
through 4 must be connected to one power source and the power cables inslots 5 through 8 must be connected
to another power source.
i) Verify that the OK LED turns on and eventually becomes green.
Installing or Replacing a 3-kW Universal AC/DC Power Supply
Before You Begin
•
The power source must be installed within reach of the power cables.
•
The power source must meet the power specifications required by the switch.
•
There are one or two power sources available. If using n+n redundancy, there must be two power sources
available. Otherwise, only one power source is required.
Step 1
Open the packaging for the new 3-kW Universal AC/DC power supply and inspect the module for damage.
If the module is damaged, contact the Technical Assistance Center (TAC).
Step 2
If you are installing the module in an empty slot, remove the blank filler plate that is already in that slot by unscrewing
its captive screw and pulling it out of the slot. If you are using the combined power mode or n+1 redundancy, you can
use any power supply slot in the chassis. If you are using n+n redundancy mode, you must be sure that you are inserting
the power supply in a slot used for the desired power supply (the power supplies in slots 1 through 4 must be connected
to one power source and the power supplies in slots 5 through 8 must be connected to the other power source). Go to
Step 4.
Step 3
If you are replacing a power supply that is currently in the chassis, remove the existing module from the chassis by
following these steps:
a) Turn off the power to the power supply that you are replacing as follows:
1
Shut off the power supply by setting its power switch to 0.
2
If the power supply is connected to a DC circuit, shut off the circuit at the circuit breaker.
3
Verify that the OK LED has turned off (indicates that there is no power going to the power supply).
The FAULT LED might be on and amber colored to indicate that the power source connection has been
broken.
Note
4
Remove the power cable plug from the power supply receptacle.
