Installation Process

6.Termination - Only Internal or Only External Devices Check that the drive channel is properly terminated according to drawings below. The AcceleRAID 352 controller 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 2-10for an example of an internal drive configuration. See Figure 2-11for an example of an external drive configuration.
