Control Panel LEDs

In addition to the LEDs built into the power and UID buttons, each of the four control
panels located on the front of the SC827HD-R1400B chassis has two LEDs that
provide you with critical information related their own node. This section explains
what each LED indicates when illuminated and any corrective action you may need
to take.
Overheat/Fan Fail
When this LED is solid on it indicates an overheat condition. When it fl ashes quickly
(~ once every second), it indicates a fan failure. When it fl ashes slowly (~ once every
four seconds) on the node A control panel, it indicates a power supply failure. An
overheat condition 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 cover is properly 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.
NIC
Indicates network activity on any of the LAN ports when fl ashing

Green: When illuminated, the green LED on the front of the drive carrier indi-
cates drive activity. A connection to the backplane enables this LED to blink on
and off when that particular drive is being accessed.
•
Red: The red LED serves two functions:
•
When solid on (not fl ashing), this LED indicates a hard drive failure.
•
When this LED fl ashes on and off it indicates the HDD is rebuilding.
