Chapter 1 General Description
4.3.3 LAN (1 - 2) Link/Access Lamps
The lamp blinks when data is being transmitted through the LAN port. 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 Guides of the EM card and the switch module
installed in the Blade Enclosure.
4.3.4 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 rack 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 also goes on.
You may use the remote control feature of EXPRESSSCOPE Engine 3 (BMC) to perform the same operation
as using the ID switch on the server.
4.3.5 SSD Access Lamp
The lamp lights while accessing to a Solid State Drive occurs (however, if the Solid State Drives are operated
in the RAID System, the lamp operates only in the OS boot status).
The lamp is lit amber if a Solid State Drive cannot be interfaced with the CPU blade correctly due to a
hardware fault in the CPU blade or another failure.
In the RAID System, the lamp blinks green or amber alternately while the Logical Drives are 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.
