Doing More with Your CD-ROM Drive 4-7
Enabling and Disabling Jumpers
A jumper exists in two states: enabled or disabled. A jumper is
enabled when a plastic hood called a jumper block is placed over the
jumper’s two pins as shown in Figure 4-1.
In contrast, a disabled jumper is one in which the jumper block is not
placed over the jumper’s two pins as shown in Figure 4-2.
Configuring the Master/Slave Jumper Setting
You can set your drive as the Master or Slave drive using the
Master/Slave Jumper at the back of the drive. The factory default is
Slave.
The instructions below show you how to connect an additional
GCD-R542B to your drive. If your additional drive is not
GCD-R542B, refer to the documentation that comes with your drive.
To configure your drive to Master or Slave:
1. Remove the jumper blocks from the Master/Slave Jumper of
your drive.
