Status LEDs and Buttons
3
System status
•
Green—The system is running in normal operating condition.
•
Green, blinking—The system is performing system initialization and memory
check.
•
Amber, steady—The system is in a degraded operational state. For example:
–
Power supply redundancy is lost (power supply unplugged or failed).
–
CPUs are mismatched.
–
At least one CPU is faulty.
–
At least one DIMM is faulty.
–
At least one drive in a RAID configuration failed.
•
Amber, blinking—The system is in a critical fault state. For example:
–
Boot failed.
–
Fatal CPU and/or bus error is detected.
–
System is in an over-temperature condition.
4
Fan status
•
Green—All fan modules are operating properly.
•
Amber, steady—One fan module has failed.
•
Amber, blinking—Critical fault; two or more fan modules have failed.
5
Temperature status
•
Green—The system is operating at normal temperature.
•
Amber, steady—One or more temperature sensors have exceeded a warning
threshold.
•
Amber, blinking—One or more temperature sensors have exceeded a critical
threshold.
6
Power supply status
•
Green—All power supplies are operating normally.
•
Amber, steady—One or more power supplies are in a degraded operational state.
(An event warning threshold has been reached, but the power supply continues
to operate.)
•
Amber, blinking—One or more power supplies are in a critical fault state. (A
critical fault threshold has been reached, causing the power supply to shut down.)
7
Network link activity
•
Off—The Ethernet link is idle.
•
Green—One or more Ethernet LOM ports are link-active.
•
Green, blinking—One or more Ethernet LOM ports are traffic-active.
8
Internal-drive status LEDs
Use these LEDs to indicate the location of a failing drive. Then open the system cover
to find exactly which drive is failing by looking at the LEDs on the drive trays.
•
The two columns of LEDs correspond to the two halves of the internal drive
compartment (under either the right- or left-side top cover).
•
The four numbered rows of LEDs correspond to the four horizontal rows of drive
bays (14 drive bays in each row).
for an example. In this example, the red LED indicates that the failing
drive is in the right half of the internal drive compartment, in row 3.
