Cabling and Power Up

Turning on Housekeeping Power and Logging in to the MP

After connecting the serial device, log in to the Management Processor (MP). +3.3 V DC Housekeeping power

(HKP) (also known as standby power) is active as soon as AC power is applied to the server. As the MP uses

housekeeping power, it is possible to log in to the MP even with the power switch in the OFF position. The

power switch is a DC power switch that controls +48 V DC.

Before powering up the HP 9000 rp7420 Server server for the first time:

1. Verify that the AC voltage at the input source is within specifications for each server being installed.

2. If not already done so, power on the serial display device.

The preferred tool is the CE Tool running Reflection 1.

To power up the MP, set up a communications link and log in to the MP:

1. Connect the server to AC power.

On the front of the HP 9000 rp7420 Server, a solid green Standby Power LED, a solid green MP

Present LED, and a flashing amber Attention LED will illuminate after about 30 seconds.

2. Check the bulk power supply LED for each BPS.

When on, the breakers distribute power to the BPSs. AC power is present at the BPSs:

• When power is first applied. The BPS LEDs will flash amber.

• After approximately 30 seconds have elapsed, the BPS LED will flash green. (If the LED stays amber,

the BPS may be defective or the power may not be within specifications.) Observe that the flashing

amber BPS LED transistions to a flashing green LED for each BPS.

Refer to power cord policies to interpret LED indicators.

3. Log in to the MP:

a. Enter Admin at the login prompt. The login is case sensitive.

It takes a few moments for the MP prompt to display. If it does not, be sure the laptop serial device

settings are correct: 8 bits, no parity, 9600 baud, and None for both Receive and Transmit. Then, try

again.

b. Enter Admin at the password prompt. The password is case sensitive.
