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 prior to Release 5.0, UBIC-Hs support unprotected, 1:1, and 1:N (where N 5)
protection groups. In Software R5.0 and greater, UBIC-Hs additionally support available high-density cards
in unprotected and 1:N protection (where N 2) protection groups.
Table 1-15 shows protection groups and their applicable slot assignments.

EIA Replacement
Before you attach a new EIA, you must remove the backplane cover or EIA already installed on the ONS
15454. Refer to the spare document(s) for the EIA type(s) you are removing and replacing for specific
information.
Coaxial Cable
Caution! Always use the supplied ESD wristband when working with a powered ONS 15454. Plug the
wristband cable into the ESD jack located on the lower-right outside edge of the shelf assembly.
When using ONS 15454 DS-3 electrical cables, the cables must terminate on an EIA installed on the ONS
15454 backplane. All DS-3 cables connected to the ONS 15454 DS-3 card must terminate with coaxial
cables using the desired connector type to connect to the specified EIA.
The electromagnetic compatibility (EMC) performance of the node depends on good-quality DS-3 coaxial
cables, such as Shuner Type G 03233 D, or the equivalent.
DS-1 Cable
DS-1 cables support AMP Champ connectors and twisted-pair wire-wrap cabling. Twisted-pair wire-wrap
cables require SMB EIAs.
Twisted Pair Wire-Wrap Cables
Installing twisted-pair, wire-wrap DS-1 cables requires separate pairs of grounded twisted-pair cables for
receive (in) and transmit (out). Prepare four cables, two for receive and two for transmit, for each DS-1
