The NVRAM, power, and server
status LEDs indicate whether the server is powered, its operational state, and
whether the NVRAM is currently being protected by the super capacitor’s backup
power. The way an LED flashes provides further information about what is currently
occurring.
The following tables describe the various power status LEDs.
Table. NVRAM status LED
(green/amber)
State |
Meaning |
Green (solid) |
Normal operation |
Amber (solid) |
The NVDIMM or Supercapacitor backup
energy source is faulty. |
Off |
Disabled or system powered down. The
NVDIMM may contain data in internal flash memory that will be
restored on boot. |
Table. Power status LED
(green)
LEDs |
Meaning |
Green |
Normal operational mode of an active
cluster node. |
Slow flash (once every three seconds) |
The system has been shut down.
|
Medium flash (once every .8 seconds) |
The server is available to host file
services but is not currently doing so. This also occurs if no EVS
is configured, or if all EVSs are running on the other node in a
cluster. |
Fast flash (five flashes per second) |
The server is rebooting. |
Off |
The server is not powered up.
|
Table. Server status LED
(amber)
LEDs |
Meaning |
Amber |
Critical failure and the server is
not operational. |
Slow flash (once every three seconds) |
System shutdown has failed. Flashes
once every three seconds. |
Medium flash (once every .8 seconds) |
The server needs attention, and a
non-critical failure has been detected, for example, a fan or power
supply has failed. Flashes once every .8 seconds. |
Off |
Normal operation. |
