Before You Begin

The MGC-50 and the MGC-100 are high performance, high capacity Multipoint Control Units (MCU) which support up to 48 po rts for the MGC50, and 96 ports for the MGC-100. They utilize a variable port bandwidth ranging from 56 to 1920 Kbps.

Figure 1-1: MGC 50

Figure 1-2: MGC 100

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 formation of different configurations based on users’ 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 immedi ately.

2-2

Figure 2-1: MGC-100 package

2. Place the MGC-100 unit on a stable flat surface in a location that meets the MGC environment requirem ents, which are:

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

• Humidity: 15%–90% non-condensing

• Altitude: Up to 3,000m (10,000ft)

• ESD: +8 kV

3. Release the clasp locks at the bottom, and lift the MGC-100 top cover.

Figure 2-2: Unpacking the MGC-100

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 MG C-100, the 3” above the unit is not needed. Refer to the NEBS Standards for clearance compliance.

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 brac kets to the rack securing it with bolts and self-locking nuts (which the client provides).

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

usually pre-installed:

1. Make sure that the MCU power is turn ed OFF and that it is disconnect ed 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.

2-4

4. Remove both MCU side covers.

5. Remove the plates from the both sides of the MGC by removing the appropriate number of functional modules to allow access to the screws.

8. Place the MCU in a 23” rack and while supporting it, screw the mounting brackets to the rack securing 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

Item # 3

Item #4

Because of heat considerations, the MCU must be installed with the Control Unit Module placed on the left bottom.

1. Check that all the parts are i n 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-

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 spring washer (Item #3) onto the screw (#2). b. Fit the flat washer (Item #4) onto the screw.

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

to the MGC-100 unit with the screws (wit h the attached washer s, as described in step b).

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 di fferently 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.

MGC-100 Dongle

MGC-100 is shipped with a serial dongle installed on COM 1 on the MCU rear panel. The dongle is required for normal operation of the MCU. If the dongle is missing, please contact support.

Connecting to the power source

Y o u can connect to an AC Inl et or to DC power supply acc ording to the power system used in your site. Follow the steps appropriate to your power system.

The following restrictions apply to the conductors and connectors that may be used to ground the unit when rack mounted:

• When using bare conductors, they must be coated with an appropriate

antioxidant compound before crimp connections are made. Tinned, solder-plated or silver-plated connectors do not have to be prepared in this manner.

• The same bolt assemblies should not secure multiple connectors.

• Listed fastening hardware must be compatible with the materials being

joined and must be preclude loosening, deterioration and electrochemical corrosion of the hardware and joint materials.

To connect to the AC Inlet:

1. Make sure the power switch is OFF. Insert the power cable into the power connector on the rear panel of the MGC-100 unit.

2. Insert the power cable into the power source socket.

3. Turn on the power by pressing on the power switch located on the rear panel of the MGC-100 unit.
