Troubleshooting a DC power supply
WARNING:
For equipment using –(48–60) V DC power supplies, a qualified electrician must perform all connections to
DC power and to safety grounds. Do not attempt connecting to DC power or installing grounds yourself. All electrical
wiring must comply with applicable local or national codes and practices. Damage due to servicing that is not authorized
by Dell is not covered by your warranty. Read and follow all safety instructions that came with the product.
CAUTION:
The system requires one power supply for normal operation. On power-redundant systems, remove and
replace one power supply module at a time when a system is turned on.
CAUTION:
A single power supply module can be removed from a switched-on array for a maximum of five minutes.
Beyond that time, the array may automatically shut down to prevent damage.
NOTE:
In case a power supply module fails, make sure to leave the failed power supply module in the enclosure till the
replacement power supply module is available.
NOTE:
You must unlatch and lift the optional cable management arm if it interferes with power supply removal. For
information about the cable management arm, see the system's rack documentation.
1. Verify that the power switch is in the ON position.
2. Locate the faulty power supply and determine the status of the LEDs.
If the line input LED is not lit, check the power cable and power source to which the power supply is connected.
•
Make sure that the power cable is securely attached to the power source and the power supply.
•
Connect another device to the power source to verify if it is working.
•
Connect the cable to a different power source.
•
Replace the power cable.
3. Reseat the power supply by removing and reinstalling it.
