Diskette write-protect switch setting:
The
diskette write-protect switch controls whether you can write
information to a diskette using a diskette drive. The ability
to prevent writing to a diskette is particularly useful if you
are concerned about the security of information that can be
obtained through a network.
Note
This switch does not affect the ability to read
information from a diskette.
Notes

Power-off the server and all other connected
devices.

Disconnect all external cables attached to the
server; then, remove the server cover.
1. Locate the configuration switches (also known as
rocker switches) on the system board. For more
information, refer to the label inside the server, or see
“System board illustration” on page 142.
2. For normal diskette operation or for read-only diskette
operation, set switch 8 as shown in the following
illustration. It might be helpful to use the end of a
small screwdriver to set the switch.
Attention:
The following illustration is for reference only. Before
you change the settings for switch 8, be sure that you
check the orientation of the server system board to
correctly identify the switch number locations. If you
change the settings for the wrong switches, you might
seriously damage server components or options.

3. After changing configuration switch settings, you must
reconfigure the server. After reassembling the server
(see “Completing the installation” on page 77), use
the Configuration/Setup Utility program to reset the
date and time, reset any passwords, and reconfigure
the server. For more information, see
“Configuration/Setup utility program menus” on
page 24.
