Hardware Installation
196 AP-4131 Access Point Product Reference Guide
To install a BIAS-T system using a single BIAS-T unit and access point:
Steps 1-3 could involve running Ethernet cabling through industrial walls or
ceilings. Only a qualified contractor should perform this kind of cabling.
1. Attach one end of a RJ-45 patch cord (5-50 ft.) to the access point. Run
the other end of the RJ-45 patch cord through a ceiling or wall into a
punch down termination box.
2. Run a CAT-5 Ethernet cable from the punch down termination box to
another punch down termination box in the wall or ceiling near the
intended location of the BIAS-T unit.
3. Secure a second RJ-45 (5-50 ft.) patch cord from the punch down
termination box to the output connector on the right-hand side of the
BIAS-T unit.
