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.

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.
You can install UBIC-Hs on one or both sides of the ONS 15454. As you face the rear of the ONS 15454
shelf assembly, the right side is the A side (15454-EIA-UBICH-A) and the left side is the B side
(15454-EIA-UBICH-B). The diagrams adjacent to each row of SCSI connectors indicate the slots and ports
that correspond with each SCSI connector in that row, depending on whether you are using a high density
(HD) or low density (LD) configuration.
Note: UBIC-H EIAs will support use with the high-density (DS3/EC1-48, DS1/E1-56, and DS3XM-12)
electrical cards, as well as existing low-density electrical cards.
Figure 1-21 shows the A- and B-side connector labeling.
