Be sure the UPS batteries are charged to the
proper level for operation. See the UPS documentation for
details.
Be sure the UPS power switch is in the On
position. See the UPS documentation for the location of the
switch.
Be sure the UPS software is updated to the
latest version. Use the Power Management software located on the
Power Management CD.
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.
Be sure the line cord is connected.
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.
Check the UPS LEDs to be sure a battery or
site wiring problem has not occurred. See the UPS
documentation.
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.
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.
