Section 2. Installing Your PlexCombo 

PlexCombo 20/10/40-12A Installation and Users Manual  

 

You specify your drive's Master or Slave setting before installing it. You do this by 
changing the position of a jumper on the mode jumper block at the rear of the drive.  
 
Your drive ships from our factory with its mode jumper set to operate the 
PlexCombo as a Master. This will work in most custom system configurations. If 
your computer is from a large OEM system manufacturer such as IBM, Hewlett 
Packard, Gateway or Compaq, you will need to pay particular attention to whether 
the system utilizes a Cable Select scheme.  

As shown in Figure 4, the PlexCombo drive arrives from the factory with its mode 
jumper set to Master. (A function is ON if the jumper is installed and OFF if the 
jumper is removed.) 
 

 
Changing to a Master, Slave, or Cable Select  
The Master/Slave setting for the drive is determined by the mode jumper. To change 
the drive from Master to Slave or to Cable Select, you must move the jumper.  
 
For example, to change the PlexCombo drive to be a Slave, move the jumper to the 
middle set of pins, leaving the other pins uncovered. To change the drive for Cable 
Select, move the jumper to the left set of pins. (Note that if any device is jumpered as 
Cable Select, then both devices on that cable must be jumpered the same.)
