UID

Depressing the UID (Unit Identifi er) button illuminates an LED on both the front
and rear of the chassis for easy system location in large stack confi gurations. The
LED will remain on until the button is pushed a second time. Another UID button
on the rear of the chassis serves the same function. See the table in Figure 3-1
for descriptions of UID LED states.

Control Panel LEDs

The control panel located on the front of the SC116 chassis has fi ve LEDs. These
LEDs provide critical information related to different parts of the system. This section
explains what each LED indicates when illuminated and any action that may be
required. See Figure 3-1 for the locations of the LEDs.

Universal Information LED

When this LED blinks red quickly, it indicates a fan failure and when blinking red
slowly a power failure. This LED will be blue when used for UID (Unit Identifi er).
When on continuously 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 properly (see Chapter
5). This LED will remain fl ashing or on as long as the indicated condition exists.
See the table below for descriptions of the LED states.
Note: deactivating the UID LED must be performed in the same way it was activated.
(If the UID LED was activated via IPMI, you can only turn the LED off via IPMI and
not with the UID button.)
