Installation Process
2-12 AcceleRAID 170 Installation Guide
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 2-9 for an example of an internal drive configuration.
See Figure 2-10 for an example of an external drive configuration.
