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 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 must have a terminator installed; the
controller 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.
