SCSI devices which meet NSE and LVD speciﬁcations. Contact the local HP sales representative for a current list of SCSI devices supported by HP for use on the Ultra Narrow Single-Ended and Ultra2 Wide Low-Voltage Differential SCSI buses.
Page 207 SCSI connections SCSI restrictions higher performance SCSI bus than previous SCSI buses and is more sensitive to adherence to the electrical speciﬁcations. Low-voltage differential signaling speciﬁcations are described in the SCSI Parallel Interface-2 (SPI-2) document and in the Electrical Characteristics of Low Voltage Differential Signaling (LVDS) Interface Circuits TIA/EIA-644 document.
Page 208: Scsi Bus Length Constraints
The maximum cable length for a Ultra Wide Low-Voltage Differential SCSI bus is 12 meters. The HP workstation c-class uses 1 meter of this maximum cable length internally. This means that up to 11 meters of cable can be used for connecting external Ultra2 Wide Low-Voltage Differential SCSI devices to this workstation.
Page 209 NOTE When calculating the total Ultra2 Wide Low-Voltage Differential SCSI cable/bus/trace length used externally, remember to account for cables connecting external devices together as well as the bus length internal to those devices.

Page 210: Assigning Scsi Device Ids
SCSI connections assigning SCSI device IDs assigning SCSI device IDs Before assigning a SCSI device ID to your drive, you need to check the existing SCSI device IDs. To determine which SCSI device IDs are available for your device, use the ioscan command in a terminal window: 1.
Page 211: Assigning Ultra Narrow Single-Ended Scsi Device Ids
assigning Ultra narrow single-ended SCSI device IDs You can determine which Ultra Narrow Single-Ended SCSI (NSE SCSI) devices are currently in use by reviewing the output from the ioscan command discussed above and looking under the “H/W Path” heading. The entry 10/0/15/0 is the built-in Ultra Narrow Single-Ended SCSI bus.

Page 213 NOTE It is necessary to put a terminator on unused SCSI connectors on the rear panel, or the last device connected to the SCSI bus. Terminators are shipped with the system. Only use a NSE SCSI terminator for the NSE SCSI bus and a FW LVD terminator for the FW LVD SCSI bus.
