MGC+100 Hardware Installation

Inspecting the MGC+/ReadiManager IAM Package Contents

You should inspect the shipped box and note if it was damaged in any way. If the box items show damage, you should file a damage claim with the carrier who delivered it.

When deciding on a setup locati on for the MGC+, refer to the section “System Safety” on page 2-2.

Disclaimer

Polycom is not responsible for damage sustained during shipment of this product.

System Safety

This section includes the follow topics related to system safety:

• “General Safety Precautions” on page 2-2

• “Rack Mount Safety Precautions” on page 2-3

• “Polycom MGC+/ReadiManagerReadiManager Precautions” on page 2-

General Safety Precautions

Follow these rules to ensure general safety:

• Keep the area around the Polycom ReadiManager clean and free of

clutter.

• The MGC+50 weighs approximately 24 kg (53 lbs) and the MGC+100

weighs approximately 48 kg (106 lbs). When lifting the system, two people at either end should lift slowly with their feet spread out to distribute the weight. Always keep your back straight and lift with your legs.

2-2

Rack Mount Safety Precautions

The following precautions should be followed with regards to rack mount safety:

• Decide on a suitable location for the equipment rack that will hold the

MGC+/ReadiManager unit. It should be situated in a clean, dust-free area that is well ventilated. Avoid areas where heat, electrical noise and electromagnetic fields are generated. You will also need it placed near a grounded power outlet.

• Ensure that the leveling jacks on the bottom of the rack are fully

extended to the floor with the full weight of the rack resting on them.

• In a single rack installation, stabilizers should be attached to the rack.

• In multiple rack installations, the racks should be coupled together.

• Always make sure the rack is stable before extending a component from

the rack.

• Y ou should extend only one component at a ti me - extending two or more

simultaneously may cause the rack to become unstable.

• Before you install the rails, determine the placement of each component

in the rack.

• Install the heaviest server components on the bott om of the rack first, and

then work up.

• Allow the power supply units to cool before touching them.

• Always keep the rack’s front door and all the blade’s panels and

components closed when not servicing, to maintain proper cooling.

The MGC+ unit is designed to provide maximum reliability, minimum interruptions, and effortless maintenance. Removable active components are accessed via the front panel to provide quick and easy serviceability. Redundant power supplies are easily accessed via the front panel, ensuring a fail safe operation (the MGC+50 power supply is not redundant, therefore not hot-swappable). Network connections on the back of the unit enable easy module removal and prevent accidental disconnection.

All Functional Modules are front-removable and hot-swappable, allowing servicing functions to be performed while the system is in operation.

The operator accesses the MGC+ unit from an operator work station which is connected to the MGC+ unit via an Ethernet interface or an RS-232 interface, as shown in Figure 3-1, “MGC+ interfaces”.

Chapter 3 - System Architecture

The MUX+ Module transfers the control information to the Main Control Module via the Control Bus. The control information i s then proce ssed by the Main Control Module and a control response forwarded via the Con tro l Bus to the appropriate MUX+ Ports.

The MUX+ module divides the incoming information into audio, video and data components, and then forwards the information to the appropriate functional module. The information arriving at the MUX+ ports is multiplexed into Nx56/64 Kbps channels. These channels can be hyperchannels or aggregated channels, depending on the capabilities of the network and the receiving terminals.

The MUX+ Module transfers audio information to the Audio+ Mod ule via the Information Highway. The audio information is then processed by the Audio+ Module and forwarded via the Information Highway to the appropriate MUX+ ports.

The MUX+ Module transfers video information to the Video+ Module via the Information Highway. There are two modes of video operation during a conference:

• Video Switching, where the speaker is the only person shown on the

screen. The MUX+ module broadcasts the vi deo of the current spea ker to all sites involved in the conference.

• Continuous Presence, where several participants are shown on the

screen. The video information is processed by the Video+ Module and forwarded via the Information Highway to the appropriate MUX+ Ports.

The MUX+ Module transfers T.120 data (which follows the ITU-T T.120 standard for data transfer and application sharing in a multipoint conference) to the Data Module via the Information Highway. The data information is processed by the Data Module and forwarded to the appropriate MUX+ Ports.

After the audio, video, and data information has been processed, the processed information flows back to the MUX+ module for multiplexing, after which it is sent to the network via th e Networ k Interface module and the Input/Output card. This information is then transferred to the Network Interface module via the Information Highway. The information is then ready for transmission.

The Main Control Module includes several connectors. These are connected to ports on the chassis. Tw o types of connectors on the rear panel provide connections from the MGC+ to various external systems. These systems include reservation systems, local or remote operator consoles, manage me nt systems and billing systems. One connector is a standard Ethernet LAN interface, which support operator workstations operating on LANs via TCP/ IP. The other connector is an RS-232 interface on COM2, which is used for local diagnostics and production purposes.

An RS-232 interface connector on COM2 the rear panel is provided for connecting to operator workstations locally or remotely (via a modem). The connector is used for local diagnostics and production purposes.

The Main Control Module Control Bus connects to the Functional Modules. The CCOM and C8M provides the interface between the Main Control

Module and the Backplane. This module also generates the MCU clock. The operating system running on the Main Control Module uses the Processor’s internal clock interrupts to set up its real-time clock. Sometimes, the operating system’ s clock may ski p one or several interrupts resulting in a time difference between the two clocks. In such a case, the operating system compares the two clocks. When a discrepancy between the two clocks is detected, the operating system updates its clock according to the Main Control processor’s clock. This feature ensures that long-term reservations start on time.

This feature does not correct any time difference between the MGC+ Manager’s clock (which is derived from the Windows operating system run on the operator workstation) and the MCU internal clock.

Backplane

The Backplane is based on the “universal slot” conc ept, where any functional card can be inserted in any functional slot. Therefore, dif fer ent configurations are formed based on the users’ port capacity and functionality requirements. The Backplane supports hot swapping of Function Modules and all I/O cards.

In the MGC+100, the front of the Backplane contains 16 slots for Functional Modules and an additional slot (Slot 1) for the Main Control Module. The back of the Backplane contains 16 slots for I/O cards (15 slots for I/O and 1 slot for the Main Control Module). The Network Interface Modules connected via the Backplane to I/O cards, which connects the system to the network. The Power Supply Module provides power to the Backplane via a power bus.

Chapter 4 - Hardware Description

Information Highway

The Information Highway is a high capacity TD M-type bus. It is used b y both the MGC+100 and the MGC+50. The Information Highway transfers information from the Network Interface Modules to the MUX+ Modules and from the MUX+ Modules to the Audio+, Video+ and Data Modules except during IP calls. In IP calls (H.323 and SIP) the information is transferred directly to the IP+ network module and from there t o the Audio +, Video+ and Data modules.

Powerplane

The MGC+100, as opposed to the MGC+50, uses a Powerplane. Up to three Power Supply Modules can be plugged into the Powerplan e. The Powerplane and Power Supply Modules are designed to accommodate hot swapping of

power supplies.

In the MGC+50, there is one power supply, which is connected to the backplane and fans via wire leads.

4-12

Power Supply Module

Both MGC+ units (MGC+100 and MGC+50) operate at 100-240 volts AC 50/60 Hz.

Power Module in the MGC+100

Three redundant power supplies provide backup for the system to ensure multipoint service is not interrupted as a result of any single power supply failure. The Power Supply Modules are hot swappable and connect to the Powerplane, which is part of the Backplane.

The power supply automatically senses the AC input voltage. Two Power Supply Modules are required to power a full system. Three Power Supply Modules are installed on the MGC+, with one power

supply providing redundancy. Should one power supply fail the other two power modules are sufficient to power the MCU.

The capacity of each power supply module is shown in Table 4-1.
