Hardware For The 2145 Ups - IBM 2145UPS-1U Hardware Installation Manual

Load-level indicators
The load-level indicators show the percentage of the 2145 uninterruptible power
supply (2145 UPS) capacity that the SAN Volume Controller 2145-4F2 is using.
When all the indicators are lit, the power requirements of the SAN Volume
Controller 2145-4F2 have exceeded the capacity of the 2145 UPS.
Site wiring fault indicator
The site wiring fault indicator on the 2145 uninterruptible power supply (2145
UPS) shows that either a ground wire connection does not exist or the live and
neutral wires are reversed in the input power connection.
The site wiring fault indicator is located on the front panel of the 2145 UPS.
Battery service indicator
The battery service indicator is located on the front panel of the 2145
uninterruptible power supply (2145 UPS) and shows that the charge in the battery
has become low while the 2145 UPS is in battery mode.
The alarm continues to beep once every five seconds. The application programs
immediately complete and save the work to prevent loss of data. If the 2145 UPS
shuts down, it automatically restarts when the main power returns.
Battery mode indicator
The battery mode indicator shows that the 2145 uninterruptible power supply
(2145 UPS) is operating on batteries.
The battery mode indicator lights up when the main power source fails and the
2145 UPS is running on battery power. The alarm beeps once every five seconds.
When main power returns, the 2145 UPS returns to normal mode and the battery
recharges. The battery mode indicator then shuts off and the alarm ceases.
General alarm indicator
The general alarm indicator on the 2145 uninterruptible power supply (2145 UPS)
turns on when a power or temperature problem occurs.
When the general alarm indicator is accompanied by the audio alarm beeping
every five seconds, the battery is low. If the audio alarm is continuous, the internal
temperature of the 2145 UPS is too high or there has been a momentary output
overload.
