Overview
Introduction
The 1 GHz GainMaker® Broadband High Gain Balanced Triple (HGBT) RF
Redundant Node has a plastic cable track that helps to protect the power and RF
cables while routing them from the node housing lid to the RF Launch Amplifier
located in the node housing base.
It is possible for this cable track to bend in such a way, as the node housing lid is
It is possible for this cable track to bend in such a way, as the node housing lid is
being closed, that the cable track may damage or even dislodge a capacitor located
on the Optical Interface PWB (OIB). This capacitor is responsible for a 10-second
time delay in switching from an RF backup signal path to an optical signal path
following restoration of a fiber loss. If the capacitor is damaged or dislodged, any
subsequent switchover from an RF backup signal path to a restored optical path
occurs immediately, rather than after a 10-second delay.
Purpose
The purpose of this document is to provide instructions for installing a Power
Cable Track Guide, part number 4020093, on the OIB. The proper installation of
the Power Cable Track Guide should prevent possible physical contact between
the cable track and capacitor.
Audience
This document is intended for any customer who has purchased the GainMaker
HGBT RF Redundant Node.
Qualified Personnel
Only appropriately qualified and skilled service personnel should attempt to
install, operate, maintain, and service this product.
