LEDs

This section describes indications and meanings of the LEDs on NovaScale/ft Server series.
See "NAMES AND FUNCTIONS OF COMPONENTS" earlier in this chapter for the locations of each LED.
POWER LED
This LED lights green while the server is powered on. When power is off, this LED is off. The LED also lights green
when one of CPU/IO modules is powered on.
DISK ACCESS LED
This LED indicates the status of hard disk drives loaded on 3.5-inch disk bays. Whenever the hard disk drives are
accessed, the LED blinks green.
When this LED lights amber, it indicates a hard disk drive has a problem. You can see the status of the failed hard disk
drive by checking the LED of each hard disk drive.
If this LED is blinking amber, it indicates volumes in hard disk drives are not mirrored. See "DISK OPERATIONS" (in
chapter 3) to configure mirror volumes.
FT Status LED
The LED stays green while the server is running normally in DUPLEX mode. If this LED is off or lights/blinks amber,
there is something wrong with the server.
The table below shows indications of the FT Status LED and their meanings.

The table below shows indications of CPU/IO module status LEDs, their meanings, and actions to be taken.

Action
Wait for a while; it will light green and the mode will become Duplex
shortly after POST.
The LED indicates only one of modules is running. If this status is
observed right after the system startup or activation of a module that
has been stopped, wait for a while. The status will change to the
Duplex mode with the LED lit in green.
If the LED does not light green after a few minutes, a device
(FC-connected storage, internal disk) that should be redundant may
not be attached properly. Check to see devices to make sure they
achieve redundancy.
Check the CPU/IO module status LEDs to find the failing module,
and then report your sales agent which LED of the failing module is
blinking.
Wait for memory dump to be completed.
