Note: All models include an Ultra160 SCSI controller with a five-drop multi-mode terminated LVD SCSI cable. Single-Ended devices attached to this cable will limit the entire SCSI bus to single-
ended performance. All tape drives and external tape enclosures are supported by PCI Wide Ultra160 SCSI Adapter (P/N 19K4646) which includes a five-drop multi-mode terminated LVD SCSI cable
and an external 0.8-mm VHDCI connector.
1. To determine cable requirements, note the tape drive’s SCSI interface, the appropriate SCSI controller from the system configurator section, and the desired enclosure, then refer to Appendix D:
Cables - Storage Units - Controllers.
2.This single-ended device will limit the SCSI bus to which it is attached to Ultra SCSI speeds. To provide a dedicated tape SCSI bus, install PCI Wide ultra160 SCSI Adapter (P/N 19K4646) which
includes a five-drop multi-mode LVD SCSI cable.
3. For RAID configurations where the standard SCSI cable is attached to a RAID adapter, the two-drop multi-mode terminated LVD SCSI cable included with Media Bay Tray and LVD Cable Kit P/N
10K2340 is required, to allow attachment of a SCSI Tape Drive to the standard Ultra160 SCSI controller.
4. Requires 68-pin External Multimode LVD/SE SCSI Terminator P/N 00N7956.
5. LVD support for LVD devices installed in a NetMEDIA Storage Expansion Unit EL (P/N 03K8756) requires replacement of the standard single-ended internal cables with one or more (depending on
configuration) cables from Media Bay Tray and LVD Cable Kit (P/N 10K2340) which contains a single two-drop mult-mode LVD-SCSI terminated cable. If the standard cables are used for attachment
to LVD devices, single-ended SCSI rules and bus speeds apply.
6. Provides a black desktop 133 mm (5.25”) half-high (HH) tape enclosure. Connector is configurable as 50-pin Centronix or 68-pin high density. Requires either tape drive self termination or 68-pin
External Multimode LVD/SE SCSI Terminator (P/N 00N7956).
7. NetMEDIA Storage Expansion Unit EL (P/N 03K8756) is a black 3U, 19” rack-mountable tape enclosure which includes two full high (FH) or four half high (HH) extended length 133 mm (5.25”)
bays, two external 68-pin high density connectors and two internal four-drop single-ended terminated 16-bit SCSI cables for device attachment. Two power supplies and two power cords are also
included.
Tip: The front rail clips will need to be reversed and screwed in from behind to secure the unit in a Rack Cabinet P/N 930842X.
8. NetMEDIA Systems Management Adapter (P/N 10L7113) may be installed in an Expansion Unit P/N 03K8756 to provide repeater function, LVDS interface, aggregate cable lengths up to 12 meters
when attached to an LVD SCSI controller, and auto-termination when the Expansion Unit is powered off. External connector is 0.8-mm VHDCI.
