2. Indications of Disk Lamps on Trays
Disk lamp Indication Description

Rapid blink Access to HDD now.

Supplies power to HDD. Does not indicate that HDD is
defected.
ON during operation
Indicates that HDD is defected or SATA cable is removed.
If HDD is defected, replace it with new one and perform
rebuild process.
Umber
Slow blink Indicates that rebuild process is executed.
Notice
Without accesses, the green lamp may blink frequently. This does not
indicate the occurrence of a failure.
It is caused by routine monitoring accesses by NEC ESMPRO or the disk
array controller itself or periodical accesses from OS. In addition, due to the
nature of the disk array controller, the blinking period against a single
access is rather long. Such accesses may cause frequent blinks to occur.
Check
Some servers cannot be equipped with additional HDD cages or can
only be equipped with different types of additional HDD cages. Contact
your service representative for details.
The disk lamps are controlled by a driver. The umber lamp goes on in
installation of OS or every boot of the server. However, this does not
indicate the occurrence of a fault. The umber lamp goes off after OS is
started to operate the driver.
Rebooting takes place with the lamp status at rebooting remaining
unchanged.
