Commission (FCC)

Part 15: Class A Statement. This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. Test limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manuals, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case the user will be required to correct the interference at his or her own expense.

Part 68: Network Registration Number. This equipment is registered with the FCC in accordance with Part 68 of the FCC Rules. This equipment is identified by the FCC registration number.

If requested, the FCC registration Number and REN must be provided to the telephone company.

Any repairs to this equipment must be carried out by Polycom Inc., or our designated agent. This stipulation is required by the FCC and applies during and after the warranty period.

United States Safety Construction Details

Unit is intended for RESTRICTED ACCESS LOCATION.

Unit is to be installed in accordance with the National Electrical Code.

The branch circuit overcurrent protection shall be rated 20 A for the AC system.

This equipment has a maximum operating ambient of 40°C, the ambient temperature in the rack shall not exceed this temperature.

For DC system only:

Use 10 AWG copper conductors.

Connect to a reliably grounded 48 V DC SELV source.

Caution: This equipment has a connection

between the earthed conductor of the DC supply circuit and the earthing conductor. See Installation Instructions.

This equipment shall be located in the same immediate area (such as, adjacent cabinets or any other equipment that has a connection between the grounded conductor of the same DC supply circuit and the grounding conductor, and also the grounding connection of the DC system.) The DC system shall not be grounded elsewhere.

Before You Begin

The MGC-50 and the MGC-100 are high performance, high capacity Multipoint Control Units (MCU) which support up to 48 ports 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

1-1

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 immediately.

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 provides). -or-

If 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.

4.Remove both MCU side covers.

Chapter 2 - Hardware Installation

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/N- KIT2026A). 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.

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.

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.
