TMG7800 System Installation Guide
1.2 Installation Prerequisites
For the installation to proceed without interruption, it is important that you verify that you have all
necessary materials on hand.
1.2.1 TMG7800-CTRL
Adequate space for the installation of the TMG7800-CTRL
You will need to mount the TMG7800-CTRL on a 19" equipment rack (customer provided). Your
TMG7800-CTRL is a 2U unit. Plan for an additional 2U space on the equipment rack for a redundant
TMG7800-CTRL.
Note The depth of the TMG7800-CTRL is 26” (660mm) instead of 16” (406mm) depth of the
TMG7800 telecom units. It is important to plan for an equipment rack of an adequate
size.
The dimension of the TMG7800-CTRL are as follows:
• Depth x Width x Height (mm) 660 x 430 x 88
• Depth x Width x Height (inch) 26" x 16.9" x 3.5"

Introduction

Adequate power supply and power connections
Each TMG7800-CTRL requires two power connections to provide for its redundant power supply. To
guarantee an uninterrupted supply of electricity, each power connection must be fed by a dedicated
power source.
An IP address for the management port
Each TMG7800-CTRL requires a IP address for the management port. To avoid delays, you should
have the IP address, netmask and gateway addresses on hand. Take note that the management port
supports DHCP, see Section 2.3.1 “Connecting to the System Management Interface” on page 24 for
further information.
Cabling
Three (3) customer supplied ethernet cables are required for each TMG7800-CTRL to connect the
TMG7800-CTRL to the switches.
1.2.2 TMG7800 Telecom Units
Adequate space for the installation of each TMG7800 Telecom Unit
You will need to mount each TMG7800 Telecom Unit (1-16 units) on a 19" equipment rack (customer
provided). Each TMG7800 Telecom Unit is housed in a 2U chassis.
Adequate power supply and power connections
Each TMG7800 Telecom Unit requires two power connections to provide for its redundant power
supply.
To guarantee an uninterrupted supply of electricity, each power connection must be fed by a dedicated
power source.
1.2.3 TMG7800-TMS
Adequate space for the installation of the TMG7800-TMS
You will need to mount the TMG7800-TMS on a 19" equipment rack (customer provided). Your
TMG7800-TMS is a 1U unit. Plan for an additional 1U space on the equipment rack for a redundant
TMG7800-TMS.
Adequate power supply and power connections
Each TMG7800-TMS requires two power connections to provide for its redundant power supply. To
guarantee an uninterrupted supply of electricity, each power connection must be fed by a dedicated
power source.
1.3 Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It may occur if
electronic printed circuit cards are improperly handled and may cause complete or intermittent failure.

6
TMG7800 System Installation Guide
Always follow ESD prevention procedures when removing and replacing modules:
• Ensure that the Tmedia VoIP gateways are grounded.
• Wear an ESD-preventive wrist strap and ensure that it makes good contact with your
skin. Connect the wrist strap clip to an unpainted surface of the Tmedia VoIP Gateway
or the grounded equipment rack in order to channel away all ESD voltage safely to
ground. To guard against ESD damage and shocks, the wrist strap and cord must be
in proper working condition.
• If no wrist strap is available, and you must work with Tmedia VoIP Gateways, ground
yourself by touching a metal part of the chassis.
1.4 Recommended Reading
This document assumes that you have a clear understanding of the installation of the TelcoBridges
Tmedia VoIP gateways and have been trained to work with the equipment.If you have any technical
questions, TelcoBridges TB Support (technical support team) can be reached via telephone (+1 866

Installing the Equipment
11
2.2 Rack Mounting the Tmedia TMG7800 VoIP Gateway
Equipment
The Tmedia TMG7800 VoIP Gateway equipment is mounted on a customer provided equipment rack
using the mounting hardware packaged in each box.
2.2.1 Prerequisites
To rack mount the equipment, you will need:
• One customer-provided equipment rack, measuring 19” in width and 31.5” in depth. The rack must
be solidly anchored to the floor with appropriate support at the top of the racks.
• Climate controlled room: 0 to +50 Celsius, 0 to 95% non-condensing humidity.
2.2.2 Vertical Placement of Tmedia TMG7800 VoIP Gateway
Equipment
The TMG7800-CTRL and TMG7800 Telecom Units are each housed in a 2U chassis, while the
TMG7800-TMS is housed in a 1U chassis, as tabulated in table 2.1 on page 11. It is important that you
provide for enough room on the equipment rack to allow for the installation of the equipment.
Consider the available space on your equipment rack and the height of one (1) or two (2) TMG7800-
CTRL unit(s), one (1) to sixteen (16) TMG7800 Telecom Unit(s), and from zero (0) to two (2) TMG7800-
TMS units. Due to the rear-exhaust heat vents and the efficient heat dissipation design, there is no need
to leave any physical vertical space above or below the TMG7800-CTRL unit(s), TMG7800 Telecom
Unit(s), and the TMG7800-TMS unit(s) on the equipment rack.
Table 2.1 Tmedia VoIP Gateway Physical Height

TMG7800 System Installation Guide
2.2.3 Installing the Tmedia TMG7800 VoIP Gateway on an Equipment
Rack
The TMG7800-CTRL, TMG7800 Telecom Unit, and TMG7800-TMS are mounted on a 19" equipment
rack using the angle brackets and screws provided in the box.
2.2.3.1 TMG7800-CTRL
Mounting the TMG7800-CTRL Unit(s):
The TMG7800-CTRL is installed in a 19” equipment rack using one of the following two methods:
Method One: Slider Rails
1. Install the left sliding rail on the left-hand side of the equipment rack.
1a. Attach the front end of the slider rail to the front edge of the equipment rack. See figure 2.1 on
page 13.
1b. Attach the rear end of the slider rail to the rea edge of the equipment rack. See figure 2.2 on
page 13 and figure 2.3 on page 14.
2. Repeat Step 1 to install the right sliding rail on the right-hand side of the equipment rack.
3. Extend both sliding rails. See figure 2.4 on page 14.
4. Attach the TMG7800-CTRL to the rails. See figure 2.5 on page 15 and figure 2.6 on page 15.
5. Push the TMG7800-CTRL back into the equipment rack until it locks into place.
Note To unlock the rails and slide the TMG7800-CTRL outwards from the equipment rack,
depress the purple colored buttons on each side of the sliding rails.
