Enabling and Disabling the Power-On Password

Before you begin:

 Read “Safety Considerations” on page 4-2 and “Handling Static Sensitive

Devices” on page 4-3.

 Remove the server cover (see “Removing the Cover” on page 4-4).

Your server arrives from the factory with the power-on password enabled (but unset).

You can disable the power-on password by changing the position of a jumper on the

system board.

Notes:

1. Moving the jumper to the default position re-enables the power-on password,

unless it has been removed in the System Management Services Utilities or by

removing the battery.

2. If you

forget

the power-on password, you can erase the password by shutting

down the server and removing the battery for at least 30 seconds. See

“Changing the Battery” on page 4-36 for details on removing the battery.

3. The server power cable

must

be disconnected before removing the battery.

To disable the power-on password, complete the following steps:

1. Locate jumper J20 using the following illustration.

2. Remove any adapters that are blocking the jumper.
