Terminators are a vital part of your SCSI chain: without proper termination your SCSI bus will not function. Make sure your external HPDB68 SCSI cable is properly terminated with the TEU320EXTM68. Compatible with Ultra320/Ultra160 SCSI drives, this multi-mode terminator works with both LVD and SE signaling. Like all our SCSI terminators, the TEU320EXTM68 is constructed with the highest quality components and is backed by our lifetime warranty.
