Installing the High-Density Electrical Interface

Assemblies on the Cisco ONS 15310-MA

Product Name: 15310-EIA-HD-A, 15310-EIA-HD-B

This document explains how to install and remove high-density electrical interface assemblies (EIAs)

on the Cisco ONS 15310-MA.As appropriate, use this document in conjunction with the

Cisco ONS 15310-CL and Cisco ONS 15310-MA Procedure Guide, the Cisco ONS 15310-CL and

Cisco ONS 15310-MA Reference Manual, and the Cisco ONS 15310-CL and Cisco ONS 15310-MA

High-Density EIA Description

High-density EIAs are attached to the ONS 15310-MA shelf assembly backplane to provide up to 168

transmit and receive DS-1 connections through six Champ connectors per side (A and B) or six transmit

and receive DS-3/EC-1 connections through six BNC connectors per side. The 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.

Note The HD expansion connectors on the high-density EIA are not supported in Software Release 7.0.x and

earlier.

You can install EIAs on one or both sides of the ONS 15310-MA. As you face the rear of the shelf

assembly, the right side is the A side (15310-EIA-HD-A) and the left side is the B side

(15310-EIA-HD-B).

High-Density EIA Installation

Figure 2 High-Density EIA Installation

High-Density EIA Installation

To install the EIA on the rear of the shelf assembly, you must first remove the standard sheet metal

covers. The EIAs use the same screw holes as the standard sheet metal covers, but they use three holes

for panhead screws and two holes for jack screws.

When installed with the standard door and cabling on the backplane, the ONS 15310-MA shelf measures

approximately 13.7 inches deep when fully populated with backplane cables.

Install the High-Density EIAs

The following parts are needed to install the high-density EIAs.

•#2 Phillips screwdriver

•High-density EIA(s)

•6-32 x 5/16-inch pan head screws (3, included with EIA)

Caution Always use the supplied ESD wristband when working with a powered ONS 15310-MA. Plug the

wristband cable into either of the ESD jacks, on the far left and right faceplates in the shelf.

Install the High-Density EIAs

Step 1 Remove the blank sheet metal covers. Use a Phillips screwdriver to remove the five screws holding each

sheet metal cover in place.

Figure 3 shows the screw locations of the sheet metal covers installed on the A- and B-side of the ONS

15310-MA.

Figure 3 Blank Sheet Metal Covers

Step 2 Determine which high-density EIA is designed for installation on the B Side and which is designed for

installation on the A Side (Figure 2 on page 3).

Step 3 Align the connectors on the EIA you want to install with the mating connectors on the backplane, using the

plastic guide posts on the connectors.

Caution Do not firmly apply pressure to the EIA; this could damage the EIA and backplane connectors.

Step 4 Seat the EIA as flat as possible by gently exerting enough pressure with your hands to only partially seat the

connectors. Do not try and fully insert the EIA.

Step 5 Locate the two jack screws on the EIA, which are found on the opposite corners (Figure 2 on page 3). (For

example, on the B-side EIA, the screws are located in the top right and bottom left corners.)

Step 6 Starting with either jack screw, tighten the thumb screw turn five full turns, then turn the other thumb

screw five full turns (Figure 4). Alternate between the jack screws until the EIA is full seated onto the

chassis and the jack screws are hand tight. The EIA is fully mated when both jack screws are fully threaded

into the chassis.
