2-18 General Description
LAN (1 - 4) Link/Access Lamps
The lamp is on when the 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 the LAN port is physically controlled by the EM card and the switch module installed
in the Blade Enclosure.
To check the connection status of the 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 turns the lamp on, and pressing it again turns the lamp off. The ID lamp
identifies a specific CPU blade in a system where more than one CPU blade is installed. Turning
this lamp on can help to identify a faulty device.
If you press the ID switch, the lamp turns 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 green when the hard disk drive is accessed. The lamp lights amber if a fault occurs
in the hard disk drive or CPU blade.
In the disk array configuration, the lamp blinks amber while the disk array is rebuilt (this does not
indicate an error). After rebuilding completes, the lamp returns to the normal indication. If
rebuilding fails, the lamp lights amber.
