SCSI Termination
Correct SCSI termination procedures require that the last device on the SCSI bus be termi-
nated. If the last device is not terminated or if devices other than the last are terminated, 
erratic SCSI bus behavior may occur. 
An auto-detection, on-board terminator is built into the RAID subsystem. You do not need to 
install an external terminator when a subsystem acts as the last device in the daisy chain con-
figuration. The on-board terminator default is enabled. If the subsystem is not the last device 
in the daisy chain configuration, the terminator will be automatically disabled. Although it is 
not recommended, if you prefer to disable the firmware setting for the on-board terminator 
using the LCD keypad panel on the subsystem, RS232C terminal session, or Bosch RAIDWatch 
management software, the auto-detection function is also disabled. 
Typically, the host computer or host adapter (SCSI card inside the PC) is the first device and 
some are already terminated. When installing the RAID subsystem on a SCSI bus with other 
devices, be sure to observe the above rules regarding all devices on the SCSI bus. Consult 
your host computer and/or host adapter manual for additional information on correct termina-
tion procedures.
i
NOTICE! 
It is recommended not to change the firmware default setting for the SCSI terminator so the 
auto-detection function can operate.
