Replacing an EdgeLink 100 interface cable
Replace an EdgeLink 100 interface cable to restore communication with a
port on a DS3 FP.
Prerequisites
• You must be familiar with “Safety considerations and best practices”
(page 53).
• The interface cables that connect an EdgeLink 100 to a Passport 15000
or 20000 or the Ethernet hub of a Preside Multiservice Data Manager are
listed in the table “Interface cables between an EdgeLink 100 and a
Passport 15000 or 20000” (page 812). Two cables are required, one for
transmitting and one for receiving.
Procedure steps
1 Using the table “Interface cables between an EdgeLink 100 and a
Passport 15000 or 20000” (page 812), and using the labels at the cable
ends, locate the end points of a cable path.
2 If the interface cable is from a DS3, make a cable the same length with
the same type of connectors. attach the appropriate connector to the
cable according to the manufacturer’s instructions.
If the interface cable is from a DS1, use the prefabricated cables.
3 Route the replacement cable to both end points and loosely tie-wrap it in
place.
4 Duplicate the cable labels of the original cable onto the replacement.
5 At both ends of the cable, unplug the cable to be replaced and plug in the
replacement.
6 Manage any cable slack so that it is away from the Passport 15000 or
20000.
7 You may wish to remove the old cable. If removal means tugging on or
potentially crimping other in-service cables, leave it where is and cut off
the connectors.
8 Tighten the cable with tie-wraps along the path between the EdgeLink and
the Passport 15000 or 20000.
9 When the interface cable is connected, the software of the EdgeLink re-
establishes awareness of the links with the Passport 15000 or 20000 or
