Mode indicator
The mode indicator
1
shows the mode of the uninterruptible power supply.
When the mode indicator is steady green, the uninterruptible power supply is in
normal mode. The uninterruptible power supply checks and charges its battery as
necessary.
When the mode indicator is flashing green, the uninterruptible power supply is in
standby mode. Standby mode means that the uninterruptible power supply is
turned off, but is still connected to the main power source. No power is available
from the uninterruptible power supply output sockets.
When the mode indicator is steady red, the uninterruptible power supply is in
bypass mode because of one of the following conditions:
v The uninterruptible power supply has overheated
v
The uninterruptible power supply has an overload condition of 103% through
110% for 30 seconds
v
The uninterruptible power supply detects a fault in the battery or in the
uninterruptible power supply electronics assembly
When the mode indicator is flashing red and the alarm is sounding, the voltage
range alarm setting might not be correct. When a SAN Volume Controller is
connected to the uninterruptible power supply, the SAN Volume Controller
automatically adjusts the voltage range settings. Take no action for this alarm
condition unless it persists for more than five minutes after a SAN Volume
Controller has been connected to this uninterruptible power supply and powered
on.
