Introducing the 16-Bit UltraSCSI Hub
(Rack-Mountable)
This chapter gives a brief physical description and describes the functions and funct ional specifications of the DWZZH-S5 and DWZZH-09 UltraSCSI Hubs.
The series of DWZZH Hubs are SCSI–2 and draft SCSI–3 (ANSI X379.2/91– 10R3) compliant capable with data transfer rates of up to 40 Mbytes per second. The two versions of these Hubs are:
•
DWZZH-S5
with four host ports and one storage port, all differential. See Figure 1–1.
•
DWZZH-09:
5.25" SBBs (large) with eight host ports and one storage port, all differential. See Figure 1–2.
1.1 UltraSCSI Hub Features
Most device SCSI buses are either 8-bit or 16-bit single-ended, physical buses. Some controllers and hosts use differential buses and others use a single-ended bus. Single-ended and differential physical buses are not compatible. The UltraSCSI protocol disables both buses when they are connected together. By using an UltraSCSI Hub you can accomplish the following:
Provide radial disconnect where remaining connections can continue to
•
operate. Provide

UltraSCSI Hubs only).

1.2 Product Descriptions
1.2.1 DWZZH-S5
A DWZZH-S5 large UltraSCSI Hub (See Figure 1-1) consists of two 180W power supplies, three bulkhead covers, a personality card cover, and a DWZZH-05 SBB mounted within a shelf. This model is rack-mountable, in either a horizontal or vertical position. Termination is provided by each of the host ports. A feature of the DWZZH-S5 Hub is that it is upgradeable from a five port Hub to a nine port Hub with the purchase of a DWZZH-09 Upgrade Kit. The kit contains another 5.25" SBB (large) Hub (DWZZH-A5), a tri-link and 0.5m cable, and instructions to complete the installation, and configuration for the upgrade.
CAUTION
Connecting a single-ended bus cable to the differential connector causes the SCSI bus to fail.
