Drive Active LED LED goes on (green) to indicate access over the LPr's embedded SCSI bus. This includes access to both internal and external drives. Drive Error LED Over-Temperature LED Fan Failure LED LED flashes red to indicate that one of the two drives in the hot-swap bays has failed and must be replaced. LED flashes yellow to indicate that one of the two drives is predicted to fail and should be replaced. You may have time to back up the drive before replacing it. NOTE: You may have to remove the front bezel to see the specific drive LEDs and determine which device is in trouble. LED flashes red when any one of several temperature sensors within the LPr indicates damage to the system is imminent. Power down the system immediately. LED flashes yellow to indicate internal temperature is nearing damaging levels. Perform a graceful shutdown and power down the system. LED flashes red to indicate a fan failure. Power down the system immediately. LED flashes yellow to indicate a fan is a lower than normal speed. Unless the over -temperature indicator is flashing red or yellow, you may perform a graceful shutdown and then power down the system and correct the fan problem. This indicator reports on the power supply fan as well as the three fans in the internal LPr fan pack.

) to indicate access over the LPr's embedded SCSI bus.
This includes access to both internal and external drives.
Drive Error LED
LED flashes
red
to indicate that one of the two drives in the hot-swap bays
has failed and must be replaced.
LED flashes
yellow
to indicate that one of the two drives is predicted to fail
and should be replaced. You may have time to back up the drive before
replacing it.
NOTE
: You may have to remove the front bezel to see the specific drive LEDs
and determine which device is in trouble.
Over-Temperature LED
LED flashes
red
when any one of several temperature sensors within the LPr
indicates damage to the system is imminent. Power down the system
immediately.
LED flashes
yellow
to indicate internal temperature is nearing damaging
levels. Perform a graceful shutdown and power down the system.
Fan Failure LED
LED flashes
red
to indicate a fan failure. Power down the system
immediately.
LED flashes
yellow
to indicate a fan is a lower than normal speed. Unless the
over -temperature indicator is flashing
red
or
yellow
, you may perform a
graceful shutdown and then power down the system and correct the fan
problem.
This indicator reports on the power supply fan as well as the three fans in the
internal LPr fan pack.
