8. Termination - Only Internal or External Devices (Standard)
Check that the drive channel is properly terminated according to
drawings below. The AcceleRAID 150 is equipped with automatic
SCSI termination circuitry which handles automatic enabling and
disabling of on-board termination. For example, if the controller board
is at the end of the SCSI bus, it automatically enables on-board
termination.
If all the SCSI devices on a channel are connected either to the
internal connector or to the external connector, the end of the SCSI
bus farthest from the controller board must have a terminator installed;
the controller board automatically enables on-board termination.
See Figure 2-9 for an example of an internal drive configuration.
See Figure 2-10 for an example of an external drive configuration.
