NTP- A5 Install the EIAs

NTP-A5 Install the EIAs

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.

Note EIAs are normally factory installed. Verify that the correct EIA is installed on the shelf assembly. If not,

install the correct EIA.

Note You do not need to power down the shelf before removing or installing an EIA. An in-service upgrade

of one EIA (A side or B side) is possible if all electrical traffic (DS-1, DS-3, DS3XM-6, and EC-1) is

being carried on the other side.

Step 1 Complete the “DLP-A12 Install a BNC or High-Density BNC EIA” task on page 17-12 as needed. BNCs

are locking connectors; the high-density BNC provides access to every port on every card.

Step 2 Complete the “DLP-A373 Install a MiniBNC EIA” task on page 20-56 as needed. The MiniBNC allows

up to 96 DS-3 circuits on each side of the ONS 15454.

Step 3 Complete the “DLP-A13 Install an SMB EIA” task on page 17-15 as needed. SMBs allow you to access

every port on every card using more space and efficient cabling.

Step 4 Complete the “DLP-A14 Install the AMP Champ EIA” task on page 17-16 as needed. AMP Champs are

exclusive to DS-1 cables.

Step 5 Complete the “DLP-A190 Install a UBIC-V EIA” task on page 18-59 as needed. The UBIC-V (vertical)

EIAs allow you to use high-density electrical cards. The UBIC-V EIAs provide SCSI connectors.

Step 6 Complete the “DLP-A399 Install a UBIC-H EIA” task on page 20-108 as needed. The UBIC-H

(horizontal) EIAs allow you to use high-density electrical cards. The UBIC-H EIAs provide SCSI

connectors.

Purpose This procedure describes how to install electrical interface assemblies

(EIAs). Typically, an EIA panel is installed on the backplane during

manufacturing, but EIA panels can be ordered separately. Refer to the

Cisco ONS 15454 Reference Manual for descriptions of the EIAs.

cable into the ESD jack located on the lower-right outside edge of the shelf assembly.

Step 1 Verify one of the following:

•If you have the 15454-SA-ANSI or 15454-SA-HD shelf, a 100-A fuse panel (35-A fuse per shelf

minimum) should be installed. If not, install one according to manufacturer’s instructions.

•If you have the 15454-SA-NEBS3 shelf, a standard 80-A fuse panel (20-A fuse per shelf minimum)

should be installed. If not, install one according to manufacturer’s instructions.
