Maximum/Minimum Cable Lengths
Installing a Cat-5 Extender
Power is transported from the Unison system to the Cat-5 Extender using the
Cat-5E/6 cable. No power comes from the RAU. Although the bottom LED on the
Cat-5 Extender lights green when the cable is connected to either port, it is only pro-
viding power when it is correctly inserted into the port labeled “TO UNISON HUB.”
(Note that the top LED is disabled and will not light.)
1.
Verify that the Unison system is powered on and that the Cat-5E/6 cable is con-
nected into the appropriate port.
2.
At the Cat-5 Extender site, plug the Cat-5E/6 cable coming from the Unison sys-
tem into the Extender port labeled “TO UNISON HUB.” The Extender’s bottom
LED should light green if the Expansion Hub is powered on.
3.
Connect the Cat-5E/6 cable going to the RAU into the other port, which is labeled
“TO RAU.”
CAUTION:
Ensure that the cables are connected to the correct ports. Otherwise, you
may damage the RAU.
If the bottom LED does not light after you have verified that the Cat-5E/6 cable from
the Unison system is plugged into the port called “TO UNISON HUB,” then the Uni-
son system may not be powered on, the Cat-5E/6 cable may be cut/broken, or there is
a problem with the Extender. Verify that the
Unison system is connected to AC
power and the power switch is in the ON position.
