Control Panel LEDs
The control panel located on the front of the SC818TQ+-1000LP chassis has fi ve
LEDs. These LEDs 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.
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 ob-
structing 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 overheat condition exists.
