18Visitor and Community Network Access Concentrator Installation Guide

Connecting Cables to The process of connecting cables to the rack varies depending on the Rack Via Patch whether or not a patch panel is used. The procedure of connecting the

Panel punch-down blocks to the patch-panel is described in “Preparing the Site for the VCN Access Concentrator” on page 10.

Back Panel Connections

To connect the back panel of the VCN AC, use the 2 flat cables with RJ-21 connectors supplied with the VCN AC.

To connect the VCN AC to the patch-panel, perform the following steps:

1Connect the RJ-21 connector labeled “From Access Points” at the back of the VCN AC to the “From Access Points” connector on the front of the patch panel using one of the 50-pin twisted pair flat cables.

2Connect the RJ-21 connector labeled “TO PBX” at the back of the VCN AC to the “TO PBX” connector on the front of the patch panel using the second 50-pin twisted pair flat cable.
