Connecting SCSI and RAID Adapters

Two Channel SCSI Configuration
To connect SCSI devices to two separate SCSI channels, perform the
following. Note that A channel is connected to external device(s); B
channel is connected to internal device(s).
1. Power down the server.
2. Disconnect all peripheral devices from the server.
3. Unlock and remove the server side panel.
4. Connect the cables as shown in Figure 9-2.
5. If using the top 5¼-inch drive bay, connect the appropriate power
cable to the device.
6. Replace and lock the side panels.
7. Connect all external devices and then power on your server.
8. Run the SCU and/or RAID utilities to configure your server.
Refer to Chapter 2, “Server Utilities,” and to your SCSI and RAID
documentation for additional configuration information.
NOTE: Servers with this configuration are shipped with an
additional terminator to enable you to split the storage backplane.
