For a disk array, set SCSI bus termination so that removing or adding a SCSI device does not disturb termination. The connectors between the two ends of the channel can connect SCSI devices that have termination enabled. See the manual for each SCSI device to disable termination.

The PERC 3/DC or PERC 3/DCL can provide SCSI termination automatically at one end of the SCSI bus. The other end of the SCSI bus can be terminated by attaching an external SCSI bus terminator module to the end of the cable, or by attaching a SCSI device that internally terminates the SCSI bus at the end of the SCSI channel.

Step 5—Install the PERC 3/DC or PERC 3/DCL Controller

Choose a 3.3 V or 5 V PCI slot and align the PERC 3/DC or PERC 3/DCL bus connector to the slot. Press down gently but firmly to make sure that the card is properly seated in the slot. The bottom edge of the controller card should be flush with the slot.

Insert the PERC 3/DC or PERC 3/DCL card into a 64-bit PCI slot, as shown in Figure 9-5. Screw the bracket to the computer frame.
