General Description 2-13
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 and the LAN cable is connected, the lamp on LAN
port for which the link is being established goes on. 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, the lamp blinks.
You may use the remote control feature of EXPRESSSCOPE Engine 2 (BMC) to perform the same
operation as using the ID switch on the server.
