Verifying Controller Module Operation
To verify Controller module operation:
1. Press the LED test button and check that all LEDs illuminate. Then release the LED test button.
Repeat for the second Controller module if two are installed.
2. Check the STBY (Standby) and Active LEDs.
Ÿ
If one Controller module is installed, check:
a. that the STBY LED is off
b. that the Active LED is on
c. that the Power Supply LED is on for each power supply unit installed
d. that the FAN LEDs are on
e. that the Temperature LED is off.
Ÿ
If two Controller modules are installed, check:
– that the Active LED on the active Controller module is on.
– that the STBY LED on the active Controller module is off.
– that the Active LED on the standby Controller module is off.
– that the STBY LED on the standby Controller module is on.
If any of the LEDs fail the above checks, refer to Table 8 on page 55.
Figure 20 shows the location of the LEDs on the Controller module front panel.
