Identify A Faulty Power Supply

To determine if a power supply is marginal or has failed:
1. Check the LED status on the power supply, or the power supply LEDs on the WWN bezel (card).
Refer to Table 1 for interpretation.
2. Check status using psShow.
sw0_155:admin> psshow
Power Supply #1 is OK
Power Supply #2 is faulty
Power Supply #3 is OK
Power Supply #4 is faulty
In the example above, power supplies 2 and 4 are faulty. If there were no power supplies in the slots,
they would be marked as absent. Refer to the help page for a detail description of psShow. Since
circuit 2 provides power for supplies 2 and 4, verify that the circuit is cabled and powered. The power
supplies can be installed and removed in a hot swap manner without executing any command line
utilities.

Steps For Installation and Removal

Power supply removal

1. Press on the release tab located on upper left corner.
2. Pull down the release handle.
3. Grab the release handle and pull.

Power supply installation

1. Orient the power supply so that the tab is towards the front of the switch.
2. Insert the power supply all the way into the slot and push the handle until it clicks.
3. Verify status. If the circuit is powered, a green status appears indicating it is online. Power supply
status can also be gathered from the WWN bezel located on the non-cable side of the switch.
Note:
The optimal power output for each power supply is 1000 amps. The Fabric Watch application can be
used to pro-actively monitor this value and be notified of any power output changes. The following
output indicates that all the power supplies are functioning optimally:
sw0_155:admin> psshow
Power Supply #1 is OK
Power Supply #2 is OK
Power Supply #3 is OK
Power Supply #4 is OK
Publication Number 53-0000251-02
Do not force the installation. If the power supply does not slide easily, ensure the unit is properly
oriented before continuing with the installation.
