Leds - NEC Express5800/320Fa-L User Manual

LEDs

This section describes indications and meanings of the LEDs on NEC Express5800/ft series.
See "NAMES AND FUNCTIONS OF COMPONENTS" (pages 2-8 through 2-20) for the locations
of each LED.
POWER LED
This LED illuminates in green while the server is powered on. When power is off, this LED does
not illuminate. The LED also illuminates in 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 in green.
When this LED illuminates in 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 in amber, it indicates volumes in hard disk drives are not mirrored. See
"DISK OPERATIONS" (page 3-2) to configure mirror volumes.
FT Status LED
The LED stays green while the server is running normally in DUPLEX mode. If this LED does not
illuminate or illuminates/blinks in amber, there is something wrong with the server.
The table below shows indications of the FT Status LED and their meanings.

Action
Wait for a while; it will illuminate in 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 illuminate in green after a few
minutes, a device (LAN, FC-connected storage,
or internal disk) that should be redundant may not
be attached properly. Check to see devices to
make sure they achieve redundancy.
