1.5 1.5.9 UBIC-H EIA
The UBIC-V sheet metal covers use the same screw holes as the standard sheet metal covers, but they
have 12 additional holes for pan-head screws and three holes for jack screws, so you can screw down the
cover and the board using standoffs on the UBIC-V board.
When installed with the standard door and cabling on the backplane, the ONS 15454 shelf measures
approximately 15.7 inches (399 mm) deep when partially populated with backplane cables, 16.1 inches
(409 mm) deep when fully populated, and 16.75 inches (425 mm) deep with the rear cover installed.
When installed with the deep door and cabling on the backplane, the ONS 15454 shelf measures
approximately 17.5 inches (445 mm) deep when partially populated with backplane cables, 17.9 inches
(455 mm) deep when fully populated, and 18.55 inches (471 mm) deep with the rear cover installed.
The UBIC-V EIA supports the following cards:
DS1-14, DS1N-14
DS3-12, DS3N-12
DS3i-N-12
DS3-12E, DS3N-12E
EC1-12
DS3XM-6
DS3XM-12
DS3/EC1-48
DS1/E1-56
The A and B sides each host 16 high-density, 50-pin SCSI connectors. The A-side maps to
Slots 1 through 6 and the B-side maps to Slots 12 through 17.
In Software Releases 4.1.x and 4.6, UBIC-Vs support unprotected, 1:1, and 1:N (N < 5) protection
groups. In Software R5.0 and later, UBIC-Vs also support available high-density cards in unprotected
and 1:N (N < 2) protection groups.
Table 1-10 shows the UBIC-V protection types and their applicable slot assignments.
1.5.9 UBIC-H EIA
UBIC-H EIAs are attached to the shelf assembly backplane to provide up to 112 transmit and receive
DS-1 connections through 16 SCSI connectors per side (A and B) or 96 transmit and receive DS-3
connections. The UBIC-H EIAs are designed to support DS-1, DS-3, and EC-1 signals. The appropriate
cable assembly is required depending on the type of signal.
