V.35 Shunt Procedure
If you are using an external DCE device on the WAN RS232/V.35 port, and the connection will be
a V.35 connection, the internal shunt must be moved from the RS232C (default) position prior to
cabling and power-up. The following steps detail the procedures for switching the shunt.
Step Procedure
1 Ensure that the external power supply is disconnected from the ProxyServer.
2 Turn the ProxyServer over and remove the cabinet mounting screw from the chassis.
