2-14 General Description
LAN (1 - 2) Link/Access Lamps
The lamp goes on when LAN port is connected to the network. The lamp blinks when data is being
transmitted. When the CPU blade is powered on, it becomes ready to link with the network. The
connection of LAN port is physically controlled by the EM card and the switch module installed in
the Blade Enclosure.
To check connection status of LAN port, refer to the User's Guide of the EM card and the switch
module installed in the Blade Enclosure.
ID Lamp
Pressing the ID switch brings the lamp to light, and pressing again brings the lamp to go off. The ID
lamp is intended to identify a specific CPU blade in the system in which more than one CPU blade
is installed. Making this lamp being lit can help the maintenance work to identify the faulty device.
If you press the ID switch, the lamp goes on. When the recognize command is received from
management software such as NEC ESMPRO Manager and NEC DianaScope Manager, the lamp
blinks.
Hard Disk Drive
A single hard disk drive includes one lamp.
DISK ACCESS lamp
The lamp lights while accessing to a hard disk drive occurs (however, if the hard disk drive is
operated in the array configuration using SW RAID, the lamp operates only in the OS boot status).
The lamp is lit amber if a hard disk drive cannot be interfaced with the CPU blade correctly due to a
hardware fault in the CPU blade or another failure.
In the disk array configuration, the lamp blinks green or amber alternately while the disk array is
rebuilt (this does not indicate an error). After the rebuilding completes, the lamp returns to the
normal indication. If the rebuilding fails, the lamp is lit amber.
