11. Connect the other end of the SCSI cable to the SCSI backplane or to a SCSI
device in the server. (See your server documentation or the system label inside
the server cover for the location of the SCSI connector on the backplane.)
12. If you have physical drives to install, install them now. See your server
documentation for drive installation instructions.
13. Install the server cover.
14. If you disconnected the cables and power cords in step 2 on page 13,
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, go
to “Connecting external devices to a ServeRAID-4 controller”. Otherwise, go to
Chapter 3, “Understanding RAID technology” on page 21.
Connecting external devices to a ServeRAID-4 controller
Note: You cannot attach internal and external SCSI devices to the same channel.
For example, you cannot attach devices to both external Channel 1 and
internal Channel 1. The ServeRAID-4 controllers do not support
configurations that use both the internal and external connectors on the
same channel
concurrently .
Complete the following steps to attach SCSI devices to an external channel
connector on the ServeRAID-4 controller:
1. Connect one end of a 68-pin very-high-density connector interface (VHDCI)
SCSI cable to an external channel connector on the ServeRAID controller.
Note: See “Connector locations” on page 4 for the channel connector locations.
