Troubleshooting the Power Sled
CAUTION: Remove and replace one PSU module at a time. Leave a failed PSU
module installed in the power sled until you are ready to replace it. Operating the
system with a power sled removed for extended periods of time can cause the
system to overheat.
NOTE: The 1400 W power supply module in the power sled require a 200-240 V
power source to operate.
1 Locate the power sled to be removed or the power sled that contains the
failed PSU module. The PSU module’s status indicator will either light up
green or amber. If the PSU module is faulty the status indicator lights up
amber.
2 Replace the faulty PSU module in the power sled. See the PowerEdge
C8000 Systems Hardware Owner’s Manual for more information.
NOTE: After installing a power sled with a new PSU module, allow several seconds
for the system to recognize the power supply and to determine if it is working
properly. The status indicator turns green to signify that the module is functioning
properly.
If none of the PSU modules show a fault LED and the sleds do not power
on, log into the BMC web interface and check for status messages. See
Using the Baseboard Management Controller Guide for more information.
