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.
