Check Performance of Cabinet Components

Each CP has three colored LEDs on the front panel that indicate whether it is functioning properly or not. When a cold start is performed, the system undergoes a series of self-tests and loads default translations.

Upon initial power application, each CP tests itself. The red LED on the CP lights to indicate that the test is in progress. Once the CP passes its initial tests, the red LED goes off. Then, after the main processor recognizes the CP and can communicate with it, the green LED lights. When all green LEDs are lighted, the testing and loading process is complete. This process takes about 3 minutes.

1 . Make sure that both fans in each cabinet are on and operating.

2.Make sure that the green LED on the power unit behind the fan assembly is lighted.

3.Check the CP LEDs. Table 2-Dlists the LED status of each type of C P .
