This chapter offers some suggestions to solve problems you might encounter. The potential
problems are divided into the following categories. See
settings.

39.1 Power, Hardware Connections, and LEDs

The MSC does not turn on. None of the LEDs turn on.
Make sure the MSC is properly installed in the slot and the system power is properly
connected and turned on.
Refer to the IES-6000M or IES-5000 Series User's Guide for directions and
safety warnings on installing the management switch card and power
connections for the IES-5000.
The ALM LED is on.
An alarm has been detected on the MSC, the Integrated Ethernet Switch fan or the INPUT
ALARM terminals. Examples of an alarm on the MSC are when the MSC's voltage or
temperature is outside of the normal range.
Check the logs to see the cause of the alarm. Take appropriate measures to remove the cause of
the alarm. For example, you may need to change the fan module if the fans are not operating
normally (see the IES-6000M or IES-5000 Series User's Guide for directions).
One of the LEDs does not behave as expected.
