Only verify the jumper settings in step 1. Modification of the standard factory jumper settings
on the controller is rarely necessary. Modify jumpers only under the direction of a qualified
individual, i.e. your dealer.
1. Verify controller jumper settings. Refer to pages 1 through 9 for jumper setting
information.
2. Verify termination on last drive. Verify proper setting of drive select switches on drive,
i.e. set the drive select switches for drive select 1 or 2. Refer to your drive owner's
manual for information about proper drive termination and select switches.
3. Remove the blank expansion slot bracket. Put the bracket away and save it for possible
future use. The screw will be used to hold the new controller board in place.
NOTE
Verify that the cable connectors mate properly with the board connectors. This is easily
done by checking that pin 1 on the cable mates with pin 1 on the connector. Pin 1 is clearly
marked on the board's connectors. Pin 1 on the cables is usually on the color coded side.
4. WD1003-RAH:
Attach 34-pin control connector to J1
WD10035-RAH:
Attach 34-pin control connector to J 1 if W7 is set for daisy-chained
operation.
NOTE
Normally, daisy-chaining implies that two drives connect to the same connector. That is
still true with the WDl0035-RAH. However, it is possible to connect the second drive to J5.
Regardless of the connection, one drive must be configured as drive 0 and the other drive
must be configured as drive 1.
Attach drive 1 's 34-pin connector to J 1 and drive 0's 34-pin connector to J5 if W7 is set
for parallel connection. (Refer to Table 2 for further information.) Set the drive select
jumpers on both drives to drive 0 if W7 configures the controller for parallel connection.
WDl003-RA2:
Attach 34-pin control connector J5.
WDl003A-RA2:
Attach 34-pin control connector to J4.
5. Connect control cable(s) to drive(s).
6. WD1003-RAH WDl003S-RAH: Attach drive 0's 20-pin data connector to J2.
