Lan (1 - 2) Link/Access Lamps; Id Lamp; Hard Disk Access Lamp - NEC Express5800 Series User Manual

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 blinks.
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 Hard Disk Access Lamp

The lamp lights while accessing to a Hard Disk Drive occurs (however, if the Hard Disk Drives are operated in
the RAID System, 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 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.
