Introduction

Identifying the 7800 Series Gateway Equipment

---

The 7800 series gateway is comprised of the following equipment:

• One or two 7800-CTRL gateway controller(s).
• One to sixteen 7800 Telecom Unit(s).
• Based upon the configuration of your 7800 series gateway, the number of 7800-TMS media switches may range from zero to two.
• If the 7800 series gateway employs N+1 protection, one to two 7800 N+1 patch panels are used to provide protection for the TDM network.
• If the 7800 series gateway employs 1+1 protection, one to two 1 +1 patch panels are used to provide protection for the TDM network.

Installation Prerequisites

---

For the installation to proceed without interruption, it is important that you verify you have all necessary materials on hand.

A TMG7800 system can range in size from 2 to 22U in vertical rack space, at full capacity with redundant N+1 patch panels. In addition, if your system is configured to use multiple groups of 1+1 patch panels, the total vertical rack space may exceed 22U.

7800-CTRL

---

For information about the 7800-CTRL, refer to Dell’s documentation:

http://www.dell.com/support/home/us/en/04/product-support/product/poweredge-r330/manuals

Adequate space for the installation of the 7800-CTRL

You must mount the 7800-CTRL on a 19" equipment rack (customer provided). Your 7800-CTRL is a 1U unit. Plan for an additional 1U space on the equipment rack for a redundant 7800-CTRL.

The depth of the 7800-CTRL is greater than the 16” (406mm) depth of the 7800 series telecom units. It is important to plan for an equipment rack of adequate size. The dimension of the 7800-CTRL (without bezel and redundant power supply) Height x Width x Depth (mm) 42.8 x 434.0 x 625.0 Height x Width x Depth (inch) 1.68 x 17.08" x 24.60"

Adequate power supply and power connections

Each 7800-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 7800-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.

Cabling

Three customer supplied Ethernet cables are required for each 7800-CTRL, to connect the 7800-CTRL to the switches.

7800 Series Telcom Units

---

Adequate space for the installation of each 7800 Series Telecom Unit

You must install each 7800 Series Telecom Unit (1-16 units) on a 19" equipment rack (customer provided). Each 7800 Series Telecom Unit is housed in a 1U chassis.

Adequate power supply and power connections

Each 7800 Series 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.

7800-TMS

---

Adequate space for the installation of the 7800-TMS

You will need to mount the 7800-TMS on a 19" equipment rack (customer provided). Your 7800-TMS is a 1U unit. Plan for an additional 1U space on the equipment rack for a redundant 7800-TMS.

Adequate power supply and power connections

Each 7800-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.

7800 N+1 Patch Panel

---

Adequate space for the installation of the 7800 N+1 Patch Panel

If your system employs N+1 protection, you will need to mount the 7800 N+1 patch panel on a 19" equipment rack (customer provided). Your 7800 N+1 patch panel is a 1U unit. If your system is using Automatic Protection Switching (APS), plan for an additional 1U space on the equipment rack for a second 7800 N+1 patch panel.

Adequate power supply and power connections

Each 7800 N+1 patch panel 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.

7800 1+1 Patch Panel

---

Adequate space for the installation of the 7800 1+1 Patch Panel

If your system employs 1+1 protection, you will need to mount one or two 7800 1+1 patch panels on a 19" equipment rack (customer provided). Your 7800 1+1 patch panel is a 1U unit.

Adequate power supply and power connections

Each 7800 1+1 patch panel 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.

7800 RJ48C Patch Panel

---

Adequate space for the installation of the 7800 RJ48C Patch Panel

In a standalone configuration, you will need to mount one or two 7800 RJ48C patch panels on a 19" equipment rack (customer provided). Your 7800 RJ48C patch panel is a 1U unit.

Adequate power supply and power connections

Each 7800 RJ48C patch panel 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.

Preventing Electrostatic Discharge Damage

---

Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. This may occur if electronic printed circuit cards are improperly handled and may cause complete or intermittent failure.

---

Always follow ESD prevention procedures when removing and replacing modules: Ensure that the equipment is 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 equipment 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 the equipment, ground yourself by touching a metal part of the chassis.
