Mode indicator
The mode indicator provides status information on the 2145 uninterruptible power
supply (2145 UPS) and is located on the front panel.
When the mode indicator is a steady green, the 2145 UPS is in normal mode. The
2145 UPS checks and charges its battery as necessary.
When the mode indicator is flashing green, the 2145 UPS is in standby mode.
Standby mode means that the 2145 UPS is turned off but is still connected to the
main power source. No power is available from the 2145 UPS output sockets but
the 2145 UPS monitors and charges its battery as necessary.
When the mode indicator is steady red, the 2145 UPS is in bypass mode because of
one of the following conditions:
v
The 2145 UPS has overheated
v The 2145 UPS has an overload condition of 103% through 110% for 30 seconds
v The 2145 UPS detects a fault in the battery or in the 2145 UPS electronics
assembly
When the mode indicator is flashing red and the alarm is sounding, the voltage

adjusts the voltage range setting. Take no action for this alarm condition unless it
