Configuration & Specifications
ShoreGear 220T1A Voice Switch RJ-21X Port Pinout
An RJ-21 telephone cable, wired straight through, allows the ShoreGear 220T1A Voice
Switch to connect to a standard 12-port patch panel or 12-port harmonica block. When
connecting to a 24-port patch panel, the voice switch' s six analog extension ports map to
ports 1 and 3 and ports 17, 19, 21, and 23 on the patch panel. The Power Fail Transfer
Unit provides an electrical connection between trunk channel 1 and the extension on
channel 12.

Network Configuration
Once the ShoreGear voice switch is installed and powered on, it must be configured for
network operations. A voice switch gets a network configuration by assignment from a
DHCP or BOOTP server, or directly from an administrator console (see procedure below).
For more information on setting up a switch for automatic configuration by a DHCP or
BOOTP server, see the ShoreTel Planning and Installation Guide.
Configuring the Voice Switch from a Console
1. Use a straight-through serial cable, DB9 male to DB9 female, 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 login prompt, enter:
Login: anonymous
Password: ShoreTel
4. Choose Menu Options and follow the onscreen instructions for setting network
parameters, including IP address, subnet mask, and gateway.
