General Description 2-13

LAN (1 - 4) Link/Access Lamps

The lamp goes on when LAN port is connected to the network. The lamp flashes 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 (SIGMABLADE-H).

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

flashes.

DISK ACCESS Lamp

A hard disk drive has one lamp.

The lamp lights green while accessing to a hard disk drive occurs. 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 flashes amber 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.
