Control Panel Components
Component Description
A The main power button on each of the four control panels is used to apply or
remove power from the power supply to each of the four nodes in the chassis.
Turning off system power with this button removes the main power but keeps
standby power supplied to the system. Therefore, you must unplug the server
before servicing.
B This LED indicates network activity on the LAN when flashing.
C The overheat LED is illuminated when an overheat condition occurs.
– A solid red LED indicates an overheat condition in the system.
– A flashing red LED that flashes in one-second intervals indicates a fan failure.
– A flashing red LED that flashes in four-second intervals indicates a power
failure.
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 and air
shrouds are installed. Finally, verify that the heatsinks are installed properly. This
LED will remain on or will continue flashing as long as the temperature is too high
or a fan does not function properly.
D This is a system ID (unit ID) button with an LED. It can be used to highlight a
system. You can activate it by the button or by software.
