Regulatory Notices United States Federal Communication 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. Taiwan CE Mark R&TTE Directive Polycom Inc., declares that the MGC-50 and MGC-100 with NET-2/4/8 cards are in conformity with the following relevant harmonized standards: EN 60950: 1992 Including Amendments 1,2,3 & 4 EN 55022: 1994 EN 50082: 1997 Following the provisions of the Council Directive 1999/CE on radio and telecommunication terminal equipment and the recognition of its conformity. Canadian Department of Communications This Class [A] digital apparatus complies with Canadian ICES-003. Notice: The Industry Canada label identifies certified equipment. This certification means that the equipment meets telecommunication network protective, operational and safety requirements as prescribed in the appropriate Terminal Equipment Technical Requirements document(s). The Department does not guarantee the equipment will operate to the user's satisfaction. Before installing this equipment, users should ensure that it is permissible to be connected to the facilities of the local telecommunications company. The equipment must also be installed using an acceptable method of connection. The customer should be aware that compliance with the above conditions may not prevent degradation of service in some situations. Repairs to certified equipment malfunctions, may give the telecommunications company causes to request the user to disconnect the equipment. Users should ensure for their own protection that the electrical ground connections of the power utility, telephone lines and internal metallic water pipe system, if present, are connected together. This precaution may be particularly important in rural areas. Caution: Users should not attempt to make such connections themselves, but should contact the appropriate electric inspection authority, or electrician, as appropriate.

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.

The dongle is required for normal operation of the MCU. If the dongle is missing, please contact support. Connecting to the power source You can connect to an AC Inlet or to DC power supply according 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. Main Switch AC Inlet 2. 3. Insert the power cable into the power source socket. Turn on the power by pressing on the power switch located on the rear panel of the MGC-100 unit. 2-10 MGC Hardware and Installation Manual To connect to the -48DC power system: 1. Make sure the power switch is OFF. Turn off the DC power distribution unit. 2. Using the three wires 10 AWG cable running from the DC power distribution unit, connect the black wire into the -48IN terminal block and the red wire to the -48V RTN terminal block. Connect the green or green-yellow wire to the system single-point "Ground" screw. 3. COM Ground ON OFF + ON -48V IN -48V RTN OFF + -48V IN -48V RTN If the unit is rack mounted, the single-point ground on the MCU must be connected to the rack with a single conductor and attached as to prevent loosening.

Tinned, solder-plated or silver plated connectors do not have to be prepared in this manner. 4. Turn on the DC power distribution unit. 2-11 Chapter 2 - Hardware Installation 5. Turn on the power by pressing on the power switch located on the rear panel of the MGC-100 unit. Connecting the MGC-100 to the LAN Network Connect one end of a network cable to the LAN connector on the rear panel of the MGC-100 and the other end to the network. Connecting the MGC-100 to the Operator Workstation (PC) Directly via RS-232 (Optional) Connect one end of an RS-232 cable to the COM2 connector on the front panel of the MGC-100 Control Unit and the other end to the serial port of the operator station (see RS-232 Pin Assignment, A-3). 2-12 MGC Hardware and Installation Manual Connecting the MGC-100 to the Network To connect the MGC-100 to the ISDN network or T1-CAS Network: The ISDN network is optional. If the MGC-100 has to be connected to the public ISDN network then an external CSU or similar equipment is needed. T1-CAS network is optional. It allows you to connect Audio Only participants to conferences via T1-CAS lines. It uses the same network connections as ISDN and the procedure described below is applicable to both ISDN and T1-CAS lines. · Connect the 8-pin RJ-45 connector of the network cable to the NET RJ-45 jack on the rear panel of the MGC-100. Repeat this step for each of the ISDN network lines to be connected to the Network Interface card installed in the MCU. ISDN network connection ISDN Network connection for 4 spans ISDN Network connection for 8 spans Figure 2-6: ISDN network connection Leased lines should be connected using an adapter with a screw connector with solid conductor wires or a similar adapter. · Connect one side of the adapter to the NET RJ-45 jack on the rear panel of the MGC-100. Then connect the leased line wires to the other side of the adapter. The ISDN and T1-CAS network properties must be defined in the Network Services. For details, see the MGC Administrator's Guide, Chapter 3. 2-13 Chapter 2 - Hardware Installation To connect the MGC-100 to the ATM network: The MGC-100 can be connected to an ATM network. The type of connection being used differs according to the ATM Network Interface card installed in the MCU. If an ATM-25 network interface card is installed, connect the 8-pin RJ-45 connector of the network cable to the NET RJ-45 jack on the rear panel of the MGC-100. Figure 2-7: ATM-25 network connection If an ATM-155 network interface card is installed, first remove the rubber plug covering the jack. Then connect the fiber optics cable connector to the jack on the rear panel of the MGC-100. Figure 2-8: ATM-155 network connection The ATM network properties must be defined in the Network Services, For more details, see the MGC Administrator's Guide, Chapter 3. 2-14 MGC Hardware and Installation Manual To connect the MGC-100 to the IP network: If an IP network Interface card is installed in the MGC-100, connect the 8-pin RJ-45 connector of the LAN network cable to the LAN-323 RJ-45 jack on the rear panel of the MGC-100. Figure 2-9: LAN H.323 network connection When installing a NEBS compliant system, 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.
