“Load-level indicators” on page 24
The load-level indicators show the percentage of uninterruptible power supply
(UPS) 5125 capacity that the SAN Volume Controller is using.
“Site wiring fault indicators” on page 24
The site wiring fault indicator on the uninterruptible power supply (UPS) 5125
shows that either a ground wire connection does not exist or the live and neutral
wires are reversed in the input power connection.
“Battery service indicator” on page 24
The battery service indicator shows that the charge in the battery has become
low while the uninterruptible power supply (UPS) 5125 is in battery mode.
“Battery mode indicator” on page 24
The battery mode indicator shows that the uninterruptible power supply (UPS)
5125 is operating on batteries.
“General alarm indicator” on page 24
The general alarm indicator on the uninterruptible power supply (UPS) 5125
turns on when a power or temperature problem occurs.
Mode indicator
The mode indicator provides status information on the uninterruptible power supply
(UPS) 5125.
The mode indicator is located on the front panel of the UPS 5125.
When the mode indicator is steady green, the UPS 5125 is in normal mode. The
UPS 5125 checks and charges its battery as necessary.
When the mode indicator is flashing green, the UPS 5125 is in standby mode.
Standby mode means that the UPS 5125 is turned off, but is still connected to the
main power source. No power is available from the UPS 5125 output sockets but
the UPS 5125 monitors and charges its battery as necessary.
When the mode indicator is steady red, the UPS 5125 is in bypass mode because
of one of the following conditions:
v The UPS 5125 has overheated
v The UPS 5125 has an overload condition of 103% through 110% for 30 seconds
v The UPS 5125 detects a fault in the battery or in the UPS 5125 electronics
assembly
When the mode indicator is flashing red and the alarm is sounding, the voltage
range setting might not be correct. When a SAN Volume Controller is connected to
the UPS 5125, the SAN Volume Controller automatically adjusts the voltage range
setting. 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 UPS 5125 and
powered on.
On button
The on button turns on the main power to the uninterruptible power supply (UPS)
5125.
