Security Options
You can add options to your server to protect it from theft and
tampering, and to protect the data and programs stored in the
server from unauthorized access and use. Some of the security
measures that you can take are:
Ÿ Installing a U-bolt and security cable
Ÿ Setting, removing, and changing a password
Ÿ Setting the diskette write-protect switch
These options are discussed in the following sections. Chapter 2,
“Configuring Your Server” on page 15 contains more details about
setting passwords and controlling access to the diskette drives.
Additional security information is provided in the User's Reference.
Installing a U-Bolt and Security Cable
You can deter unauthorized removal of your server hardware by
installing a U-bolt and security cable on the rear of your server.
Your server comes with knockout covers over the U-bolt holes. If
you choose to connect a U-bolt to the server, you must first remove
the knockout covers.
Before you begin:
Ÿ Obtain a 19 mm (3/4 in.) U-bolt or wire rope (similar to
National Manufacturing No. 3230, Stock No. 176-735).
Ÿ
Obtain a security cable.
Ÿ
Obtain a lock, such as a combination lock or padlock.
Ÿ
Obtain a flat-blade screwdriver.
Ÿ Obtain an adjustable wrench.
Ÿ Obtain threaded nuts that fit the U-bolt.
Ÿ Read “Electrical Safety” on page 45.
Ÿ
Turn off the server.
Ÿ
Disconnect all external cables and power cords; then, remove
the server cover (see “Removing the Cover” on page 49).
