Overheat/Fan Fail:
When this LED flashes, it indicates a fan failure. When on continuously it indicates
an overheat condition, which may be caused by cables obstructing the airflow 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 flashing
or on as long as the indicated condition exists.
NIC1

Heartbeat
On the SSG-2028R-DN2R48L, this is a serverboard heartbeat LED and indicates
that power is being supplied to the serverboard.
Power Fail
Indicates a power supply module has failed. The second power supply module will
take the load and keep the system running but the failed module will need to be
replaced. Refer to Chapter 6 for details on replacing the power supply. This LED
should be off when the system is operating normally.
Power
The single button located on the right control panel is the power on/off button.
Depressing this button will either power both nodes on or off. Turning off the system
power with this button removes the main power but keeps standby power supplied
to the system.
3-3 Control Panel LEDs
The two control panels located on the front of the chassis have several LEDs. With
the exception of the power fail LED, these LEDs provide you with critical information
related to the node on the same side of the chassis. This section explains what each
LED indicates when illuminated and any corrective action you may need to take.
Power
Indicates power is being supplied to the system's power supply units. This LED
