If the date and time are not correct in the System Setup program, replace
the battery. See "System Battery" on page 115.
If the problem is not resolved by replacing the battery, see "Getting Help"
on page 179.

system seems to operate normally except for the time kept in the System Setup
program, the problem may be caused by software rather than by a defective
battery.
Troubleshooting Power Supplies
Problem
• System-status indicators are amber.
• Power-supply fault indicators are amber.
• Front-panel status LCD indicates a problem with the power supplies.
Action
1
Locate the faulty power supply.
The power supply's fault indicator is lit. See "Power Indicator Codes" on
page 19.
NOTICE: You can hot-plug the power supplies. One power supply must be installed
for the system to operate. The system is in the redundant mode when two power
supplies are installed. Remove and install only one power supply at a time in a
system that is powered on. Operating the system for extended periods of time with
only one power supply installed can cause the system to overheat.
