Installation Equipment
To install the switch, you need the following equipment:
•
AC surge protector for the power connection
•
RJ-45 cable for connecting the switch to the local area network
•
Music-on-hold source with a standard mini-headphone Y-adapter (optional)
•
Permanent earthing connector for grounding the device
•
RJ-21 telephone cable (female connector on end that is connected to the
ShoreGear voice switch) for analog port connections
•

Installation Location Requirements
To ensure optimum operating conditions for the SG-50 or SG-90 voice switch, verify
the operating environment is adequately ventilated, free of gas or airborne particles,
and isolated from electrical noise.
Installing the SG-50 or SG-90 in a 19-inch Rack
The SG-50 and SG-90 is placed in a 19-inch rack only by mounting a ShoreGear Dual
Tray into the rack, then installing the voice switch into the Tray.
Refer to the Quick Install Guide for the ShoreGear Dual Tray for Tray installation
instructions and information on using the Tray.
Mounting the ShoreGear Voice Switch on a Flat Surface
If you plan to mount the switch on a fl at surface, fi rst attach the provided rubber feet
to the bottom corners of the device. You can stack up to three switches in a surface
installation.
German: Das ShoreGear Voice-Schaltgerät auf einer ebenen
Oberfl äche montieren
Wenn Sie planen, das Gerät auf einer ebenen Oberfl äche zu montieren, befestigen Sie
zunächst die mitgelieferten Gummifüße an den unteren Ecken des Geräts. (Bei einer
Oberfl ächeninstallation 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
1.
unit and to the right of the product label.
Connect the other end of the ground wire to the wiring system ground.
2.
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
1.
Rückseite des Geräts an, die sich rechts neben dem Produktetikett befi ndet.
Schließen Sie das andere Ende des Erdungskabels an die Erde des Kabelsystems
2.
an.
VORSICHT: Schließen Sie immer zuerst den permanenten Erdungsschutz an, bevor Sie versuchen, das Gerät an ein LAN-Segment und Telekommunikationsleitungen anzuschließen.
Servicing Procedures
WARNING: The SG-50 and SG-90 contain no internal fi eld serviceable parts. Return
the equipment to ShoreTel for any required service procedures.
CAUTION: Internal fuses should be serviced only by qualifi ed ShoreTel personnel.
If internal fuses are blown and require replacement, return the SG-50 or SG-90 to
ShoreTel for service.
Connecting the ShoreGear Voice Switch to the Network
Once the SG-50 or SG-90 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.
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.
1.
Plug one end of the provided power cord into the receptacle on the back of the
2.
switch, then plug the other end into the AC surge protector.
The power LED fl ashes momentarily, and remains lit.
If the LED is not lit, make sure the power cord is plugged into the switch and the
•
power source.
If the LED continues fl ashing, there is an internal error. Unplug the switch to
•
power it off, then power it back on. Refer to the “Confi guring Switches” chapter
in the ShoreTel Administration Guide for information on fl ash 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.
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 an internal paging system.
Connect a music-on-hold source (CD player or other audio
1.
source) to the audio input port.
Connect your site’s paging system to the audio output port.
2.
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
1.
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
2.
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.
3.
CAUTION: To reduce risk of fi re, use only No. 26 AWG or larger (e.g. 24 AWG) UL Listed
or CSA certifi ed telecommunication line cord.
For detailed information on switch port and trunk confi guration, see the “Confi guring
Switches” and “Confi guring Trunks” sections in the ShoreTel Administration Guide.

Network Confi guration
Once the ShoreGear voice switch is installed and powered on, it must be confi gured
for network operations. A voice switch gets a network confi guration 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 confi guration by a DHCP or
BOOTP server, see the ShoreTel Planning and Installation Guide.
Confi guring the Voice Switch from a Console
Use a straight-through serial cable, DB9 male to DB9 female, to connect the switch
1.
to a console PC.
On the PC or laptop, start a terminal emulation program and connect to the voice
2.
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.
3.
Type 3 and press ENTER to display a menu of confi guration options.
4.
Choose Menu Options and follow the onscreen instructions for setting network
5.
parameters, including IP address, subnet mask, and gateway.
