For example:
1. Note in Table 3-1 that when you have a Switch chassis with two power
supplies and the Power Supply Fail LED lights, you should look at the back
of the chassis to see the condition of the Power Good and Over Temperature
LEDs and the Fan for each power supply to find the problem.
2. Note in Table 3-2 that when there is an AC Source disruption to a chassis
with one power supply (System Status column) that the fan is OFF and the
Power Good and Over Temperature LEDs are OFF. The state of the Power
Switch is not applicable. The Corrective Action indicates that you should
check the AC source, the plug, and the fuse.
3. Note in Table 3-1 or Table 3-2 that when the System is ON - OK, that the
Power Good LEDs on the front and back of the chassis are ON and the Over
Temperature LEDs on the front and back of the chassis are OFF.
