Installation and Servicing Connections
Mounting the ShoreGear Voice Switch on a Flat Surface
If you plan to mount the switch on a flat surface, first attach the provided rubber feet
to the bottom corners of the device. (You can stack up to three switches in a surface
installation.)
Installing the ShoreGear 220T1A in a 19-inch Rack
The SG-220T1A is placed in a 19-inch rack only by mounting a ShoreGear Dual Tray into
the rack, then installing the SG-220T1A into the Tray. You can install the SG-220T1A on
the left or right side of the tray.
Refer to the Quick Install Guide for the ShoreGear Dual Tray for Tray installation
instructions and information on using the tray.
Installation Location Requirements
To ensure optimum operating conditions for the SG-220T1A voice switch, verify the
operating environment is adequately ventilated, free of gas or airborne particles, and
isolated from electrical noise.
Installation Equipment
To install the switch, you need the following equipment:
AC surge protector for the power connection
RJ-45 cables for connecting the switch to the local area network and telco lines
Music-on-hold source with a standard mini-headphone Y-adapter (optional)
Permanent earthing connector for grounding the device
RJ-21 telephone cable (female on end connected to ShoreGear voice switch) for analog
port connections
RJ-21 to RJ-11 patch panel for connecting telephones and trunk lines
#1 Phillips screwdriver

After setting up the network connections and configuring the ShoreGear
220T1A Voice Switch for operations, you can connect your T1 line to
the switch.
Use an RJ-45 T1 cable to connect your T1 line to the Telco port.
Connecting a T1 Line
Powering on the ShoreGear Voice Switch
After connecting the switch to the network, power on the device by connecting it to an
AC power source.
Plug an AC surge protector (not provided) into a grounded AC power source.
Plug one end of the provided power cord into the receptacle on the back of the switch,
then plug the other end into the AC surge protector.
The power LED flashes momentarily, and remains lit.
If LED is not lit, verify the power cord is plugged into the switch and power source.
If the LED continues flashing, there is an internal error. Unplug the switch to power it
off, then power it back on. Refer to the “Configuring Switches” chapter in the ShoreTel
Administration Guide for information on flash patterns, or contact the ShoreTel
Support Services at http://www.shoretel.com.
The LAN ports auto-sense the network transport rate. When the network connection is
established, the network LED indicates a transport rate of 10 Mbps or 100 Mbps, and
whether the switch is receiving and transmitting data.

Once the SG-220T1A Voice Switch is secured to a rack or surface-
mounted, you can connect it to the data network. Use an RJ-45 Ethernet
cable to connect one or both of the LAN ports to the network subnet.
While both ports can detect and respond to link status, the switch uses
only one LAN port at a time.
Connecting the ShoreGear Voice Switch to the Network
Optional Connections
After connecting the voice switch to the LAN, you can make optional
connections, including input from a music-on-hold source or output to
your internal paging system.
Connect a music-on-hold source (CD player or other audio source) to
the audio input port.
Connect your site’s paging system to the audio output port.

German: Das ShoreGear Voice-Schaltgerät auf einer ebenen
Oberfläche montieren
Wenn Sie planen, das Gerät auf einer ebenen Oberfläche zu montieren, befestigen Sie
zunächst die mitgelieferten Gummifüße an den unteren Ecken des Geräts. (Bei einer
Oberflächeninstallation können Sie bis zu drei Schaltgeräte übereinander stapeln.)
Attaching an Earthing Connector
To meet electrical safety requirements for proper grounding, you must connect a
permanent earthing protector between the ShoreGear voice switch and the wiring system
ground.
Connect a ground wire (#14 AWG wire or larger) to the screw on the back of the unit
and to the right of the product label.
Connect the other end of the ground wire to the wiring system ground.
CAUTION: Always connect the permanent earthing connector before attempting to connect
the switch to a LAN segment and telecommunication lines.

German: Einen Erdungsleiter anschließen
Um den elektrischen Sicherheitsanforderungen für eine korrekte Erdung nachzukommen,
müssen Sie einen permanenten Erdungsschutz zwischen dem ShoreGear-Gerät und der
Erde des Kabelsystems installieren.
Schließen Sie ein Erdungskabel (Nr. 14 AWG oder größer) an die Schraube an der
Rückseite des Geräts an, die sich rechts neben dem Produktetikett befindet.
Schließen Sie das andere Ende des Erdungskabels an die Erde des Kabelsystems an.
VORSICHT: Schließen Sie immer zuerst den permanenten Erdungsschutz an, bevor Sie ver-
suchen, das Gerät an ein LAN-Segment und Telekommunikationsleitungen anzuschließen.

Connecting Trunk and Telephone Lines
Use the provided cable retainer to connect the voice switch to the
telephone company’s punch-down block or patch panel.
Use a #1 Phillips screwdriver to remove the two screws on either side
of the RJ-21X port, then place the retainer on the port and re-attach
the screws.

Plug the Telco cable into the port, then pull the Velcro strap tightly
around the cable connector and fasten it.
Connect the other end of the Telco cable to the punch-down block or
patch panel.

CAUTION: To reduce risk of fire, use only No. 26 AWG or larger (e.g., 24 AWG) UL Listed
or CSA Certified Telecommunication Line Cord
For detailed information on switch port and trunk configuration, see the “Configuring
Switches” and “Configuring Trunks” sections in the ShoreTel Administration Guide.

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
Use a straight-through serial cable, DB9 male to DB9 female, to connect the switch to a
console PC.
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.
At the ShoreTel login prompt, press ENTER to display the Switch Options menu.
Type 3 and press ENTER to display a menu of configuration options.
Choose Menu Options and follow the onscreen instructions for setting network
parameters, including IP address, subnet mask, and gateway.
