Figure 5-12. Verifying correct operation on the HP 630 RPS/EPS

The power on sequence and self test of the HP 620 RPS/EPS and the HP 630

RPS/EPS are the same. When the unit is powered on it will run a self test

(approximately 5 seconds). The LED behavior is described below.

LED Behavior:.

During the self test:

• Initially, all the unit and port LEDs are on and stay on for the duration

of the self test.

• All the LEDs will come on green for approximately 2 seconds, then

the dual-color LEDs will turn to amber for approximately 2 seconds

and then go off when the test is complete.

When the self test completes successfully:

•The Power, and Fan/Temp Status LEDs remain on.

•The Fault LED goes off.

• The EPS and RPS Port Status LEDs on the both the HP 620 RPS/EPS

and the HP 630 RPS/EPS go into their normal operational mode:

– If the ports are connected to active devices, the Device Connected

LEDs should be on.

– If the ports are not connected to active devices, the LEDs stay off.

If the LED display is different than what is described above, especially if the

Fault LED stays on for more than 15 seconds or it starts blinking, the self test

has not completed correctly. Refer to chapter 6, “Troubleshooting” for diag-

nostic help.

For more information on the LEDs refer to the LED section of Chapter 1, 2 or

3, for your particular RPS/EPS power supply.
