Ultra SCSI Cable Kit

ULTRA SCSI CABLE KIT

The Data Silo Ultra SCSI Cable Kit (part number DCULTRA-KIT), designed to fit the
rear panel of Kingston®'s 9-bay Data Silo rack mount or tower chassis, permits an
extended external SCSI cable length beyond the 1.5 meter limit imposed by the
SCSI 3 protocol (see figure below).

With the DCULTRA-KIT installed, a maximum Host-to-Data Silo external SCSI cable
length of 3 meters (9.84 ft) is permitted. The supplied internal ribbon cable supports
up to seven (7) internal SCSI 3 devices. Additionally, up to 3 Data Silo chassis may
be daisy-chained together, provided that each chassis is equipped with a
DCULTRA-KIT and the total external cable length does not exceed 3 meters. Note
that external SCSI cable(s) must meet the SCSI 3 (40 MBytes/sec) Specification.

An internal SCSI 3 active terminator is included with the DCULTRA-KIT. All drives
installed within the chassis must have onboard termination disabled. (Refer to the
device manufacturer's instructions for termination information). This configuration
allows LVD compatibility, but will not support maximum Ultra2 (LVD) transfer rates
(of up to 80 MBytes/sec).

The DCULTRA-KIT includes the Ultra SCSI repeater board with internal and external
SCSI connectors, internal power splitting cable, terminator, internal SCSI 3 ribbon
cable, and rear panel mounting screws.

Ultra SCSI Cable Kit

INSTALLATION

1. Disconnect all power and remove cables from the Data Silo chassis.

2. Open the Data Silo chassis to gain access to the internal cables and rear
panel I/O connectors. Refer to the Data Silo User's Guide if necessary for
information on this procedure.

3. Remove existing internal SCSI ribbon cable if installed.

4. Verify that ALL devices within the Data Silo chassis have termination disabled.

5. Remove existing chassis rear panel connector(s) if necessary.

6. Unfasten the fan power cable bracket from inside the Data Silo panel by
removing bracket screw. Remove bracket from fan power cable assembly
and discard (see Figure 1).

NOTE: The fan power cable bracket must be removed before the

DCULTRA-KIT can be installed.

7. Attach one end of the power cable to the Ultra SCSI board, attach the other end
to the Data Silo power strip. The position of existing device power cables may
need to be adjusted to accommodate the Ultra SCSI power cable.

8. Attach the Ultra SCSI repeater board to the Data Silo rear panel with the two
(2) provided screws, component-side facing away from the Data Silo panel
(see Figure 2).

9. Connect the internal SCSI ribbon cable to the Ultra SCSI board and installed
devices.

10. Reinstall the Data Silo covers and cables removed earlier.

11. If using a SCSI daisy-chain with multiple Data Silo chassis, verify that the
external SCSI cable meets the SCSI 3 (40 MBytes/sec) Specification and that
the cable does not exceed 3 meters (9.84 ft) in length.

NOTE: Ultra2 (LVD) devices can be installed with the

DCULTRA-KIT, but will only operate in Single-Ended
mode (maximum transfer rate of 40 MBytes/sec).
