3-3 Control Panel LEDs

The control panel located on the front of the SC816S-(R)400/SC816T-(R)400 chas-

sis has six LEDs, which provide you with critical information related to different parts

of the system. This section explains what each LED indicates when illuminated and

any corrective action you may need to take.

 UID: This LED turns on when either the front or the rear UID button is pushed.

Pushing either button a second time will turn this LED off.



Overheat/Fan Fail: When this LED ﬂ ashes it indicates a fan failure. When

on continuously (on and not ﬂ ashing) it indicates an overheat condition, which may

be caused by cables obstructing the airﬂ ow in the system or the ambient room

temperature being too warm. Check the routing of the cables and make sure all

fans are present and operating normally. You should also check to make sure that

the chassis covers are installed. Finally, verify that the heatsinks are installed prop-

erly (see Chapter 5). This LED will remain ﬂ ashing or on as long as the overheat

condition exists.

 NIC2: Indicates network activity on GLAN2 when ﬂ ashing.

 NIC1: Indicates network activity on GLAN1 when ﬂ ashing.
