Chapter 1 - Before You Begin

The system meets International Telecommunication Union Telecommunication Standardization Sector, (ITU-T, formerly CCITT) standards for multipoint multimedia bridging devices, and meets ETSI standards for telecommunication products. The MGC-100 DC also meets the NEBS Compliant Standard (when so ordered) for our clients based in the United States.

The flexible architecture in the system is designed to accommodate users’ changing multipoint needs. This system utilizes a modular “universal slot” platform that allows the fo rma tion of di fferent configuratio ns based on u s ers’ individual port capacity and functionality requirements.

Unpacking and Positioning the MGC-100

To unpack and position the MGC-100:

1. When you receive your MGC-100, inspect the equipment for damage and verify that the components match the packing slip. If you did not receive a component or if there is damage to the system, notify your service representative immediately.

• Operating temperature: 10°–40°C (50°–104°F)

• Humidity: 15%–90% non-condensing

• Altitude: Up to 3,000m (10,000ft)

• ESD: +8 kV

4. Lift the MGC-100 unit and remove the packaging material.

5. Lower the MGC-100 unit, placing it on the surface.

If the MGC-100 is a standalone unit, place it on a flat surface. If you are rack mounting the MGC-100, allow a minimum clearance of 3” above the unit. If you are rack mounting the NEBS MGC-100, the 3” above the unit is not needed. Refer to the NEBS Standards for clearance compliance.

Chapter 2 - Hardware Installation

Mounting the MGC-100 on a 23” Rack

The MGC-100 can be mounted to a 23” rack using the two mounting plates that are pre-installed on the unit.

1. Make sure that the MCU is turned OFF and it is disconnected from the AC or DC power.

2. Place the MCU in a 23” rack and support it, screw the mounting brackets to the rack securing it with bolts and self-locking nuts (which the client provide s).

-orIf the MGC-100 was shipped without the two mounting plates that are

usually pre-installed:

1. Make sure that the MCU power is turned OFF and that it is disconnected from the AC or DC power.

2. With a slotted screwdriver remove the five nylon plug hole covers from the MCU side covers.

3. With an Allen wrench (M4), remove the five screws from the MCU side covers.

8. Place the MCU in a 23” rack and while su pporting it , screw t he mounting brackets to the rack sec uring it with bolts and self-locking nuts.

When the unit is installed on a rack, the rack must be properly grounded to the central office ground. The rack must be grounded with two-hole compressiontype connectors using copper conductors (tinned or untinned). Wire, bus bar or braided strap connectors are acceptable.

Mounting the MGC-100 on a 19” Rack

The MGC-100 can be mounted in a 19” rack using the mounting kit (P/NKIT2026A). It is highly recommended that the 19” rack be located in an airconditioned room.

Figure 2-3 shows how to mount the MGC-100 on the 19” rack.

MGC Hardware and Installation Manual

Because of heat conside rations, t he MCU must be inst alled with the C ontrol Un it Module placed on the left bo ttom.

1. Check that all the parts are in the kit.

The kit should contain the following items:

Table 2-1: 19” Rack Mounting Kit

Item # Polycom P/N Description Quantity

1 MEC2063A 23" TO 19" Mounting Bar MGC-

100 at 90 Degrees

2 SCR2005A Screw 10-32 x 1/2” Allen S/H

ST/ST

3 WAS2003A Washer M5 Spring Latch Loc.

ST\ST

4 WAS2004A Washer M5 Flat ST/ST 8

2. Make sure that the MCU power is turned OFF and it is disconnected

from the AC and DC power. Remove the side covers as described on page 2-4.

3. If the MCU is a standalone unit, you must first remove the side covers,

and add the mounting brackets to a 23” rack (see pages 2-4 to 2-6).

4. Attach the two mounting bars to the MCU as follows:

a. Fit the sprin g washer (Item #3) onto the screw (#2). b. Fit the flat washer (Item #4) onto the screw.

Item #4

Item # 3

c. Take the two mounting bars (Item #1) from the kit and attach them

to the MGC-100 unit with the screws (with the attached washers, as described in step b).

Chapter 2 - Hardware Installation

5. Carefully rotate the MGC-100 counterclockwise 90°, making sure the Control Unit is at the bottom left.

6. While supporting the MGC-100, place it on the 19” rack and screw the brackets to the rack, securing it with the screws and nuts supplied with the rack.

NEBS Standard

For installations based within the United States, an MGC-100 DC NEBS compliant system is available. The NEBS compliant systems differs in its construction of the frame and the power supply. All else remains the same.

The construction of the MGC-100 is 12 U’s, (1 U = 4.3 cm) which makes it higher by 3 U’s than the original frame of the MGC-100. This design allows for a cushion of air to be present, ensuring safety in case of a heat related problem.

In addition, the power supply is also designed differently by allowing the circulation of cool air, providing a safety tolerance in case of a heat related problems.

Use only shielded LAN cables where the shield is grounded at both ends when connecting to the IO LAN port of the IP+48 on the MGC+ rear panel.
