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.
