Installation Process

1.Termination - Only Internal or Only External Devices Check that the drive channel is properly terminated according to drawings below, or skip to Step 2 if using both internal and external devices.

The AcceleRAID 170 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 2-9for an example of an internal drive configuration. See Figure 2-10for an example of an external drive configuration.
