Troubleshooting 53
UPS problems
UPS is not working properly
Action:
1.
Be sure the UPS batteries are charged to the proper level for operation. See the UPS documentation for
details.
2.
Be sure the UPS power switch is in the On position. See the UPS documentation for the location of the
switch.
3.
Be sure the UPS software is updated to the latest version. Use the Power Management software located
on the Power Management CD.
4.
Be sure the power cord is the correct type for the UPS and the country in which the server is located. See
the UPS reference guide for specifications.
5.
Be sure the line cord is connected.
6.
Be sure each circuit breaker is in the On position, or replace the fuse if needed. If this occurs repeatedly,
contact an authorized service provider.
7.
Check the UPS LEDs to be sure a battery or site wiring problem has not occurred. See the UPS
documentation.
8.
If the UPS sleep mode is initiated, disable sleep mode for proper operation. The UPS sleep mode can
be turned off through the configuration mode on the front panel.
9.
Change the battery to be sure damage was not caused by excessive heat, particularly if a recent air
conditioning outage has occurred.
NOTE:
The optimal operating temperature for UPS batteries is 25°C (77°F). For approximately
every 8°C to 10°C (16°F to 18°F) average increase in ambient temperature above the optimal
temperature, battery life is reduced by 50 percent.
Low battery warning is displayed
Action:
1.
Plug the UPS into an AC grounded outlet for at least 24 hours to charge the batteries, and then test the
batteries. Replace the batteries if necessary.
2.
Be sure the alarm is set appropriately by changing the amount of time given before a low battery
warning. Refer to the UPS documentation for instructions.
One or more LEDs on the UPS is red
Action: Refer to the UPS documentation for instructions regarding the specific LED to determine the cause of
the error.
