ShoreTel SG-120 Quick Install Manual

Introduction
The SG-120 or SG-24A Voice Switch package contains:
• ShoreGear 120 or ShoreGear 24A Voice Switch
• Power cord
• Stick-on feet (for surface installation)
• Cable retainer for an RJ-21 Telco cable
(a metal bracket with a Velcro strap)
About the SG-120 and SG-24A
The SG-120 and SG-24A Voice Switches connect enterprise telephone extensions
through an internal IP network, or to any central offi ce (CO) analog trunk line.
The switch provides connectivity through:
• Two RJ-45 local area network (LAN) connectors
• One RJ-21X port for connecting the switch to a telephone company punch-down
block or patch panel.
• One RJ-11 port for connection to the extension side of the Power Fail Transfer Unit
(Extension 9). Power Fail Transfer is supported only on the SG-120.
• One DB-9, 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 a music-on-hold source
• One audio output port (3.5 mm stereo) for connecting the switch to a corporate
paging system or night bell

What You Need for Installation

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 to RJ-11 patch panel for connecting telephones and trunk lines
• #1 Phillips screwdriver

Choosing a Location

To ensure optimum operating conditions for the ShoreGear voice switch, make sure
that its operating environment is adequately ventilated, free of gas or airborne particles,
and isolated from electrical noise.
Installation
Installing the ShoreGear Voice Switch (Rack Mount)
The ShoreGear voice switch is equipped with pre-installed rack-mount ears for easy
installation into a standard 19-inch rack.
Lift the ShoreGear voice switch to the
1
desired height and attach it to the frame
with four standard rack screws.
Insert the screws in both the upper and
2
lower positions on the rack-mount ears.
Verify there is at least two inches of open space
around all vent holes.
Mounting the ShoreGear Voice Switch on a Flat Surface
Before mounting the switch on a fl at surface, attach the provided rubber feet to
the bottom corners of the device. You can stack up to three switches in a surface
installation.
Attaching an Earthing Connector
To meet UL 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 (#16 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.
Installation des ShoreGear Switch (Gestell)
RJ-21X
Telco port
Der ShoreGear switch ist mit vier installierten Ösen für die einfache Installation in
einem 19 Zoll Gestell ausgerüstet.
Den SwitchGear voice switch zur
1
gewünschten Höhe heben und mit vier
ShoreGear - 120/24
standard Gestellschrauben befestigen.
Die Schrauben sind in die obere und untere
2
Position der Öse einzufügen.
Es ist sicherzustellen daß mindestens 5cm
Abstand zu allen Belüftunbgsöffnungen
vorhanden ist.
Installation des ShoreGear Voice Switch (fl ache
Oberfl äche)
Zur Installation auf einer fl achen Oberfl äche sind zuerst die mitgelieferten Gummifüße
an den Ecken des Gerätes zu befestigen. (Bis zu drei Geräte können in dieser Weise
aufeinander gestellt werden.)
Anbringen des Erdanschluß
Um UL Anforderungen zu erfüllen muß ein permanenter Erdanschluß zwischen dem
ShoreGear voice switch und dem Erdleiter des Versorgungsstromkreis hergestellt sein.
Den Erdleiter (min. #16 AWG oder größer) an der Schraube befestigen welche sich
1
an der Hinterseite und rechts des Leistungsschildes befi ndet.
2. Das andere Ende des Erdleiters ist mit dem Erdleiter des Versorgungsstromkreis zu
verbinden.
ACHTUNG: Immer zuerst die permanente Erdverbindung herstellen bevor das Gerät an
LAN Segmente oder Telekommunikations- Leitungen angeschlossen wird.
Connections
Connecting the ShoreGear Voice Switch to the Network
Once the SG-120 or SG-24A 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, verify 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 your 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
Only use a 3.5 mm stereo jack (not a mono jack) in this port.
Connecting Trunk and Telephone Lines
Use an RJ-21 Telco cable and 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
1
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
2
tightly around the cable connector and fasten it.
Connect the other end of the Telco cable to the punch-down
3
block or patch panel.
CAUTION: To reduce risk of fi re, always use #26 AWG or larger
telecommunications line cable.

ShoreTel Administration Guide.
