3-3 Control Panel LEDs
The control panel located on the front of the SC816S-400(R)/SC816T-400(R) 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.
