Connecting External Devices - IBM Netfinity ServeRAID-3H Installation And User Manual

12. If you have physical drives to install, install them now. See your server documentation for drive
installation instructions.
Notes:
a. The ServeRAID controllers use SCSI ID 7.
b. Removable-media devices (such as a CD-ROM) connected to the same ServeRAID controller
must all have unique SCSI IDs, even when they are connected to different channels. For
example, if you have a CD-ROM drive on Channel 1 set to SCSI ID 6, you must not have a tape
drive on Channel 2 or Channel 3 of the same ServeRAID controller set to SCSI ID 6.
13. Install the server cover.
14. If you disconnected the cables and power cords in step 2 on page 15, reconnect the cables and
cords. See your server documentation if you need detailed instructions.
15. If you want to attach an external SCSI device to the ServeRAID controller, continue with "Connecting
external devices." Otherwise, go to Chapter 3, "Configuring controllers using the ServeRAID Manager
program" on page 17.

Connecting external devices

To attach SCSI devices to an external channel connector on the ServeRAID controller:
1. Connect one end of a 68-pin VHDCI SCSI cable to an external channel connector on the ServeRAID
controller.
Note: See "Connector locations" on page 12 for the channel connector locations.
2. Connect the other end of the SCSI cable to the external SCSI device.
3. Go to Chapter 3, "Configuring controllers using the ServeRAID Manager program" on page 17.
4 VHDCI stands for Very High Density Connector Interface.
