The Cisco MGX 8220 edge concentrator can be used to concentrate services for a Cisco BPX 8600 series switch either from a local or remote location. The Cisco MGX 8220 can also be used as a stand alone edge concentrator.
Cisco MGX 8220 System Overview Thus, the Cisco MGX 8220 shelf supports aggregation of traffic up to 80 T1 or E1 access ports or up to 1240 64-Kbps subscribers, onto a single T3, E3, or OC-3c trunk, using only a single port on the Cisco BPX switch.
ATM trunking below T3/E3. Scalability The Cisco MGX 8220 edge concentrator aggregates traffic from as many as 80 T1 or E1 ports onto a single port of a multiport broadband trunk card. This high port density maximizes use of the Cisco BPX 8600 series high-capacity switch fabric.
The two end points of the ATM LMI signaling are an ATM LMI process in the BCC in the Cisco BPX 8600 series and an ATM LMI process in the ASC in the Cisco MGX 8220 shelf. The ATM LMI PDUs are transported over an AAL5 connection (VPI=3/VCI=31) between the BNI on the Cisco BPX 8600 series side and the BNM on the Cisco MGX 8220 side.
The ASC and the BNM modules must always be present in an Cisco MGX 8220 shelf and are referred to as the core modules. The Cisco MGX 8220 shelf supports redundant core modules where one ASC/BNM set is an active set and a second ASC/BNM is a standby set.

Inverse multiplexing for ATM trunk module—T3 to T1 (AX-IMATM-8T1/B) • This card acts as an extension of the Cisco BPX BNI card and permits the Cisco BPX ATM trunk to be used over multiple (up to 8) T1 lines instead of a single T3 line.
The MIB can be interrogated using SNMP commands. Most functions of the Cisco MGX 8220 shelf Release 5.0 can be accessed through the graphical user interface (GUI) of the Cisco WAN Manager (CWM), Release 9.2. CWM is a network and element management system that enables operations, administration, and maintenance of WAN-multiservice networks.

• Overview The Cisco MGX 8220 is a 19-inch rack-mountable shelf. This shelf provides 16 slots for holding the modules (card sets) that provide the functionality. Each slot is designed to house two cards, a front card and a back card. Cards are installed in a slot as a two card set. A backplane runs across all 16 slots to provide signal connections between front and back cards, and between slots.
The shelf can house redundant power entry modules, which are small cards installed horizontally in the bottom rear of the shelf. The Cisco MGX 8220 shelf is powered by –48V DC power sources (single or redundant pair). Each power entry module is equipped with a circuit breaker. The shelf also provides a power receptacle for a cable to the cooling assembly, which is mounted in the rack below the Cisco MGX 8220 shelf (or shelves).
Cisco MGX 8220 Backplane The Cisco MGX 8220 backplane contains a main system bus, and the cell bus for communication between card slots. The cell bus consists of two pairs of unidirectional buses (for redundancy), which are used for transferring cells between the cell bus slave modules (FRSM, AUSM, ASC) and the cell bus master (BNM).
Power Entry Options DC Powered Systems In DC-powered systems, Cisco MGX 8220 supports one or two power entry modules (PEMs) each of which can be connected to its own independent 48V DC supply. The PEMs are installed horizontally, side by side in the bottom rear of the shelf. (See Figure 2-3.) Each module is powered from a 48V DC power source using three wires.
875W of 48V DC power. The power assembly can provide power for up to four Cisco MGX 8220 shelves, requiring three power supply modules, or four for a (1 for N) redundant power supply configuration. The rear panel has four connectors which supply 48V DC power to the shelves.
The main cooling unit houses the fans that circulate air through the shelf. This unit is mounted below the shelves. This unit is capable of cooling up to two Cisco MGX 8220 shelves in the same rack. Racks that contain more than two shelves require a booster unit to provide additional cooling. The cooling assembly is powered from the main shelf.
(AC version only) Main Cooling Assembly The main cooling assembly provides cooling for up to two Cisco MGX 8220 shelves and is mounted in the rack below the shelf (or shelves). The cooling assembly consists of fans that draw air through the front grill and up through the shelf.
Cooling Assembly Booster Cooling Assembly The booster cooling assembly is used in racks with more than two Cisco MGX 8220 shelves. It is mounted above the shelves containing the main cooling assembly and below the shelves to which the booster cooling is to be provided. The booster cooling assembly consists of fans that draw air from the shelves below and exhaust air upward through the shelf or shelves above.
Optional Cisco-Supplied Cabinet Optional Cisco-Supplied Cabinet A cabinet is available from Cisco to install the Cisco MGX 8220 shelf, the Cisco BPX 8600 series wide-area switch, the ESP, and the Cisco IGX 8400 series wide-area switch.

Cisco MGX 8220 ASC Shelf Controller The Cisco MGX 8220 shelf controller (ASC) is a two-card set consisting of an ASC front card and an ASC-BC back card. The shelf can contain a single ASC card set or a dual (redundant) card set.
Some Ethernet transceivers with integrated DB-15 connectors cannot be connected directly to the LAN AUI Ethernet port on the Cisco MGX 8220 ASC back card because of interference with the ASC back card extractor levers. To overcome this problem, two Ethernet transceiver extenders (one each for a primary and secondary ASC card) are provided.
SONET SMF trunk. Each Cisco MGX 8220 shelf must be equipped with at least one BNM installed in slot 1 or slot 2. A second, redundant BNM can also be installed in slot 1 or slot 2. The primary and the redundant BNMs must be of the same type.

8-port T1 service modules. Rather than individually cable each of the 40 or 80 incoming T1/E1 lines to an MGX 8220 edge concentrator, the MGX 8220 backplane is designed with a distribution bus that allows an AX-SRM-3T3 to distribute T1s received “in bulk” to T1-based service modules. This eliminates the need for T1 back cards for each service module and the associated cabling and potential overloading of the digital cross-connect system port.

C H A P T E R MGX 8220 in Stand-alone Applications A stand-alone application is defined as one in which the MGX 8220 shelf is connected to some device (router or ATM switch) other than a BPX 8620. The interface between MGX 8220 shelf and the connected device must be ATM UNI/NNI over either T3, E3, nxT1, nxE1, or OC-3c as shown in Figure 6-1.
Configure the IP address on the connected router or ATM switch The MGX 8220 shelf uses a VPI of 3 and VCI of 8 for in-band access. The connected router or ATM switch must be able to support these values. Configure the router or switch for these VPI/VCI values.
Refer to the Cisco MGX 8220 Command Reference for details of these commands. VPI/VCI Mapping When creating connections on the MGX 8220 shelf the user does not explicitly assign VPI and VCI values. Instead, the MGX 8220 shelf takes user-entered values such as DLCI, LCN, and so forth, and uses mapping algorithms to calculate VPI/VCI values.
Enter the addport command to add a ATM port to the enabled line. Then enter the dspports command to verify that the port has been added. For example, myshelf.1.5.AUSM. a > addport myself.1.5.AUSM. a > dspports Cisco MGX 8220 Installation and Configuration Release 5.0, Part Number 78-6430-03 Rev. D0, November 2003...

Other countries—International Electrotechnical Commission (IEC) 364 Parts 1 through 7 • The MGX 8220 shelf operates safely when it is used in accordance with its marked electrical ratings and product usage instructions. The following guidelines will help to ensure your safety and protect the equipment. The list of guidelines might not address all potentially hazardous situations in your working environment, so be alert and exercise good judgment at all times.
The two 48V DC power feeds must be properly grounded on the positive 48V and safety ground pins. Ensure that the MGX 8220 frame and all other frames are attached to an isolated ground connection. For AC systems, an insulated grounding conductor that is identical in size to the grounded and ungrounded branch circuit supply conductors, but is green with yellow stripes, and installed as part of the branch circuit that supplies the unit.
The MGX 8220 shelf can be configured for either AC or DC power. An easily accessible AC or DC power source must be available within six feet of the MGX 8220 system. Before powering up the node, verify that the MGX 8220 node is powered from a dedicated branch circuit.
If you are going to mount the MGX 8220 switch in a frame or a cabinet that has front or rear doors, contact Cisco TAC to determine if the doors can provide adequate ventilation to the system.
The unit must not be operated with any unused slots left uncovered. An inventory of the installed cards is taped to the MGX 8220 shelf showing the serial number, the Note revision number, and the slot number for each card.
MGX 8220 modules are designed to be mounted to two vertical rack-mounting rails. A front-mounting rail is used as one mounting point using the flanges provided at the front of each MGX 8220 module. A second rail, either at the rear of the rack or at an intermediate position, is used for the second mounting point (mounting brackets are provided for attaching the module to the second rail).
Cooling Configuration Guidelines To ensure that the MGX 8220 switch gets proper ventilation and is cooled properly, you must adhere to the following cooling configuration guidelines: You must never have more than four (4) shelves installed between the air inlet and the air exhaust.

An alternative bracket can be used for the MGX 8220 shelf rear support. This bracket locks into slots on the module chassis and does not specifically require screws in the chassis side. Ground contacts are provided for a redundant ground connection.
The spacer guarantees the minimum necessary air exhaust space of 1.75 inches, providing the sides and rear are open and unobstructed. The MGX 8220 shelf might not be UL compliant when the spacer is used. Further, the plenum supports the attachment of a cable management kit but the spacer does not.
When this is done, however, the inclusion and positioning of MGX 8220 power, cooling, booster, plenum, and spacer modules relative to the MGX 8220 shelf must be the same as those when the MGX 8220 shelf is used in a dedicated rack.

The number of power supplies that are configured in the assembly depends upon the number of MGX 8220 shelves that have to be supported. The maximum number of MGX 8220 shelves that can be supported by a single AC power assembly is four.
The cable from the left side of the power assembly is connected to the left power entry connector in the MGX 8220 shelf. Likewise, the cable from the right side of the power assembly is connected to the right power entry connector in the MGX 8220 shelf.
Make sure that the building AC receptacle is properly grounded. Step 5 If the left power connector on an MGX 8220 shelf is not used, a cover must be installed in the empty position to ensure proper cooling of the rear cards.

Step 3 Install one or both cable supports onto the MGX 8220 shelf above the cooling module, using a number 10-32 thread forming screw for each support. Use two washers between the cable supports on the left support only.
The power cables that power the cooling module and booster module. At the MGX 8220 shelf end, the cables should be routed through the power cable support so that they can be routed down the side of the rack as shown in Figure 7-18.
Routing Data Cables Data cables that are connected to the MGX 8220 shelf back cards are routed up or down the cable management panel, where they are fed through the fingers and routed to the left or right side of the rack.
Before handling any cards, ground yourself by clipping the wrist strap that is supplied with Warning MGX 8220 shelf to a convenient metallic contact on the shelf and to your wrist. This simple procedure prevents static electrical damage to the cards.
If you accidentally attempt to insert a service module back card into slots 1, 2, 3, or 4 and have difficulty in operating the shelf, examine the backplane pins and the backcard connector to see if they have been bent or damaged. Cisco MGX 8220 Installation and Configuration 7-27 Release 5.0, Part Number 78-6430-03 Rev. D0, November 2003...
Connect two T3 coaxial cables between the T3 BNC connectors on the MGX 8220 BNM line module card and the T3 BNC connectors on the BPX BNI line module. The transmit port on the BPX line module and the receive port on the MGX 8220 BNM line module must connect to each other. (See Figure 7-22.)
T3 trunk Making the Service Interface Connections The customer data is connected to the MGX 8220 shelf through T1, E1, X.21, or HHSI lines. Service lines using DB15 and RJ-48 connectors need only one cable per port. Service lines using BNC or SMB connectors require two cables (one transmit and one receive) from the E1 port of the customer equipment to on E1 port on an MGX 8220 line module.
Making External Clock Connections If the MGX 8220 node is to be synchronized to some other external equipment or a local digital central office, a connector on the back card can be used to provide a clock input.
“MGX 8220 Service Modules,” provides details of this command. Initial Configuration Before the MGX 8220 shelf can receive commands, SNMP requests, file downloads, and so on, the shelf must be assigned IP addresses for the control port, the LAN port, and the in-band channel. This procedure requires a alpha-numeric terminal to be connected to the maintenance port of the active ASC card and addresses assigned through the command line interface.

Chapter Initial Start-Up of the MGX 8220 Shelf Step 4 While you are using the terminal, you can assign a nodename for the shelf entering the cnfname command. If you type any command mnemonic and press Return, the screen displays the syntax for Note that command.
Preventive Maintenance Most monitoring and maintenance of the MGX 8220 shelf is done using the operating system software. Preventive maintenance of the MGX 8220 shelf hardware is minimal. Periodically check the node supply voltage and internal cabinet temperature. The temperature should not exceed 50 C.
General Troubleshooting Procedures The MGX 8220 shelf run self-tests continuously to ensure proper function. When the unit finds an error condition that affects its operation, it downs the card or line that is affected. If it is caused by a card failure and there is a redundant card, the failed card is downed and the standby card becomes the active card.

There is a chance that all or part of the configuration changes could be lost. donotupdatestandby The MGX 8220 active ASC CLI command, donotupdatestandby, is used as part of an ASC graceful firmware upgrade to prevent the active ASC card from downloading firmware or configuration information to a reset standby ASC card.
Description of Upgrade/Downgrade Terminology clrallcnf The MGX 8220 active ASC CLI command, clrallcnf, is used in place of the resetsys command as part of a downgrade in which the configuration information can not be maintained for compatibility reasons. The clrallcnf command will terminate all Telnet sessions. You must reinitiate a Telnet session after an ASC card returns to the active state.
SM configuration file revision is the same between the firmware revisions involved in a downgrade, the SM configuration should be preserved (there is no need to restore the configuration).
