IU 4300T Converged Network Appliance

1 - 4

The back panel of the 4300T contains the following (left to right):

• Power connector

• Erase button

• Power connector

• 4 switched LAN Ethernet ports

• Management console port

• T1 WAN port (RJ-48 with built-in CSU/DSU)

• Ethernet WAN port

The 4300T comes with an AC power cord and power adapter for connecting to 

this port.  Little force is necessary when the plug is properly positioned.

To erase any custom configuration and restore the 4300T to its factory default 

state depress the erase button once and press again before 2 seconds expires.

This port is used to establish a local console session with the 4300T using a 

VT100 terminal or emulation program. The cable required is a 

straight-through 8-wire cable.  The serial port uses a baud rate of 9600, 8 data 
bits, 1 stop bit and no parity.

Using the Erase button as outlined above means any configuration made to the 
4300T will be lost.  Additionally the VoIP ALG registration code must be re-entered 
in the 4300T as covered in Chapter 4:  System Diagnostics, viewing the ALG 
registration code.  Erasing the configuration means that IP phones installed behind 
the 4300T will not work and Internet connectivity or network access for PCs will be 
down until the system is reconfigured.
