Network Con
fi
guration
Once the ShoreGear voice switch is installed and powered on, it must be con
fi
gured for
network operations. A voice switch gets a network con
fi
guration by assignment from
a DHCP or BOOTP server, or directly from an administrator console (see procedure
below).
NOTE:
For more information on setting up a switch for automatic con
fi
guration by a
DHCP or BOOTP server, see the
ShoreTel Planning and Installation Guide
.
Con
fi
guring the Voice Switch from a Console
1
Use a straight-through serial cable to connect the switch to a console PC.
2
On the PC or laptop, start a terminal emulation program and connect to the voice
switch using these serial communication settings:
19200 bps, 8 data bits, no parity,
one stop bit, no handshake.
3
At the ShoreTel login prompt, press ENTER to display the switch options menu.
4
Type 3 and press ENTER to display a menu of con
fi
guration options.
5
Choose Menu Options and follow the onscreen instructions for setting network
parameters, including IP address, subnet mask, and gateway.
