connected to IP phones, IADs or PCs insta ed on the oca area network (a so
known as the private network).
WAN Ethernet port
The WAN Ethernet port is a 10/100 auto sensing port that shou d be
connected to the wide area network (a so known as the pub ic network)
through a WAN termination device such as an xDSL modem or router
Erase Switch (newer hardware will say “Reset see below for switch
details)
To erase any custom configuration and restore the 4200 to its factory defau t
state depress the erase button once, wait for the LEDs to i uminate and press
again before 2 seconds expires.
 WARNING: Using the Erase switch as out ined above means any
configuration made to the 4200 wi be ost. Additiona y the VoIP
ALG registration code must be re-entered in the 4200 as covered in
Chapter 4: System Diagnostics, viewing the ALG registration code.
Erasing the configuration means that IP phones insta ed behind the
4200 wi not work and Internet connectivity or network access for
PCs wi be down unti the system is reconfigured.
Reset Switch
To perform a “soft” boot depress the reset button once, to erase the CLI
password and set it back to the factory defau t CLI password depress the
reset button twice, to erase any custom configuration and restore the 4200 to
