Install Cables With Molex 96-Pin Lfh Connectors On 120-Ohm Side; Install Cables With 1.0/2.3 Miniature Coax Connectors On 75-Ohm Side; Replace Cables With 1.0/2.3 Miniature Coax Connectors On 75-Ohm Side - Cisco ONS 15454 SDH E1-75 Installing

Install Ground and Cables
Use the nuts and washers to fix the grounding lug to the grounding bolts.
Step 5
Route the grounding cable and fix it to the to the loop farthest from the front of the cable guiding rail
Step 6
using tiewraps.

Install Cables with Molex 96-Pin LFH Connectors on 120-Ohm Side

This section explains how to install the Molex 96-pin LFH connector cables on the 120-ohm side to the
E1-75/120 conversion panel.
Guide the left Molex 96-pin LFH connector cable (channels 1 to 21) to the left and use tiewraps to attach
Step 1
it to the loop farthest from the front-left side of the cable guiding rail ( see
page
Guide the right Molex 96-pin LFH connector cable (channels 22 to 42) to the right and use tiewraps to
Step 2
attach it to the loop farthest from the front-right side of the cable guiding rail.

Install Cables with 1.0/2.3 Miniature Coax Connectors on 75-Ohm Side

This section explains how to install the 1.0/2.3 miniature coax connector cables on the 75-ohm side to
the E1-75/120 conversion panel.
Group the 42 pairs of 75-ohm cables into six groups of 7 cable pairs, so that three groups of cables
Step 1
(channels 1 to 7, channels 8 to 14, and channels 15 to 21) can be guided to the left and three groups of
cables (channels 42 to 36, channels 35 to 29, and channels 28 to 22) can be guided to the right.
Tiewrap the two groups of cables coming from the left and right sides of the E1-75/120 conversion panel
Step 2
(channels 1 to 7 and 42 to 36) to the second tiewrap fixing loop left and right, etc. with the following
groups (8-14, 35-29).
Tiewrap the last two groups of cables coming from the left and right of the center of the E1-75/120
Step 3
conversion panel (channels 15 to 21 and 28 to 22) to the left and right tiewrap fixing loops closest to the
front.
Insert the 1.0/2.3 miniature coax connector of each cable into the connector of the E1-75/120 conversion
Step 4
panel and push the connector until it clicks into position. If required, use the Y-shape end of the coaxial
connector insertion and removal tool.

Replace Cables with 1.0/2.3 Miniature Coax Connectors on 75-Ohm Side

This section explains how to replace single 1.0/2.3 miniature coax connector cables on the 75-ohm side
of the E1-75/120 conversion panel.
If you want to replace individual 1.0/2.3 miniature coax connector cables in the existing installation, first
Step 1
cut the tiewrap holding the cable that you want to replace.
