Introduction
About the ShoreGear 90BRI
The SG-90BRI Voice Switch connects enterprise telephone extensions through an
internal IP network, or to any central office (CO) ISDN BRI trunk line. The switch
provides connectivity through:
Two RJ-45 local area network (LAN) connectors
Four RJ-45 ISDN BRI ports for connecting the switch to telephone company ISDN
BRI lines
One RJ-21X port (male) for connecting the switch to a telephone company punch-
down block, patch panel, or 12-port harmonica connector
One DB-9 (female), RS-232C maintenance port (19200 bps, 8 bits, no parity, 1 stop
bit, no handshake) for serial communications
One audio input port (3.5 mm stereo) for connecting to a music-on-hold source
One audio output port (3.5 mm stereo) for connecting to a corporate paging system
or night bell

Installation Connections and Servicing
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 90BRI in a 19-inch Rack
The SG-90BRI is placed in a 19-inch rack only by mounting a ShoreGear Dual Tray
into the rack, then installing the SG-90BRI into the Tray.
Refer to the Quick Install Guide for the ShoreGear Dual Tray for Tray installation
instructions and information on using the Tray.
Connecting Trunk and Telephone Lines
Optional Connections
After connecting the voice switch to the LAN, you can make optional connections,
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 the LED is not lit, make sure the power cord is plugged into the switch and the
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 ShoreGear 90BRI 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.
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.

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.
