IBM System x3650 M3 4255 Service Guide

Attention: Before you change any switch settings or move any jumpers, turn
off the server; then, disconnect all power cords and external cables. See the
safety information that begins on page “Safety” on page vii. Do not change
settings or move jumpers on any system-board switch or jumper blocks that are
not shown in this document.
The default for all of the switches on switch block (SW4) is Off.
While the server is turned off, move switch 1 of the switch block (SW4) to the On
position to enable the power-on password override. You can then start the Setup
utility and reset the power-on password. You do not have to return the switch to
the previous position.
The power-on password override switch does not affect the administrator
password.
Administrator password: If an administrator password is set, you must type the
administrator password for access to the full Setup utility menu. You can use any
combination of between six and 20 printable ASCII characters for the password.
Attention: If you set an administrator password and then forget it, there is no way
to change, override, or remove it. You must replace the system board.
Using the Boot Selection Menu program
The Boot Selection Menu is used to temporarily redefine the first startup device
without changing boot options or settings in the Setup utility.
To use the Boot Selection Menu program, complete the following steps:
1. Turn off the server.
2. Restart the server.
3. Press F12 (Select Boot Device). If a bootable USB mass storage device is
installed, a submenu item (USB Key/Disk) is displayed.
4. Use the Up Arrow and Down Arrow keys to select an item from the Boot
Selection Menu and press Enter.
The next time the server starts, it returns to the startup sequence that is set in the
Setup utility.
Starting the backup server firmware
The system board contains a backup copy area for the server firmware. This is a
secondary copy of server firmware that you update only during the process of
updating server firmware. If the primary copy of the server firmware becomes
damaged, use this backup copy.
To force the server to start from the backup copy, turn off the server; then, place the
UEFI boot recovery J29 jumper in the backup position (pins 2 and 3).
Use the backup copy of the server firmware until the primary copy is restored. After
the primary copy is restored, turn off the server; then, move the UEFI boot recovery
J29 jumper back to the primary position (pins 1 and 2).
Using the ServerGuide Setup and Installation CD
The ServerGuide Setup and Installation CD contains a setup and installation
program that is designed for your server. The ServerGuide program detects the
server model and optional hardware devices that are installed and uses that
