THE SPECIFICATIONS AND INFORMATION REGARDING THE PRODUCTS IN THIS MANUAL ARE SUBJECT TO CHANGE WITHOUT NOTICE. ALL STATEMENTS, INFORMATION, AND RECOMMENDATIONS IN THIS MANUAL ARE BELIEVED TO BE ACCURATE BUT ARE PRESENTED WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. USERS MUST TAKE FULL RESPONSIBILITY FOR THEIR APPLICATION OF ANY PRODUCTS.

THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORTH IN THE INFORMATION PACKET THAT SHIPPED WITH THE PRODUCT AND ARE INCORPORATED HEREIN BY THIS REFERENCE. IF YOU ARE UNABLE TO LOCATE THE SOFTWARE LICENSE OR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY.

The following inform ation is for FCC compliance of Class A devices: 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. These 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 manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.

The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.

Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television communications at your own expense.

You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:

• Turn the television or radio antenna until the interference stops.

• Move the equipment to one side or the other of the television or radio.

• Move the equipment farther away from the television or radio.

• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits controlled by different circuit breakers or fuses.)

Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

Reporting Security Problems in Cisco Products

Cisco is committed to delivering secure products. We test our products internally before we release them, and we strive to correct all vulnerabilities quickly. If you think that you have identified a vulnerability in a Cisco product, contact PSIRT:

• For Emergencies only—security-alert@cisco.com

An emergency is either a condition in which a system is under active attack or a condition for which a severe and urgent security vulnerability should be reported. All other conditions are considered nonemergencies.

• For Nonemergencies— psirt@cisco.com

In an emergency, you can also reach PSIRT by telephone:

• 1 877 228-7302

• 1 408 525-6532

Tip We encourage you to use Pretty Good Privacy (PGP) or a compatible product (for example, GnuPG) to

encrypt any sensitive information that you send to Cisco. PSIRT can work with information that has been encrypted with PGP versions 2.x through 9.x.

Never use a revoked or an expired encryption key. The correct public key to use in your correspondence with PSIRT is the one linked in the Contact Summary section of the Security Vulnerability Policy page at this URL:

http://www.cisco.com/en/US/products/products_security_vulnerability_policy.html

The link on this page has the current PGP key ID in use.

If you do not have or use PGP, contact PSIRT at the aforementioned e-mail addresses or phone numbers before sending any sensitive material to find other means of encrypting the data.

How this Chapter Is Organized

Overview of Terms

Each acronym in this book is defined on its first use and in the Glossary at the end of the guide. Types of cards are also defined in the Glossary. For example, MCC is miniature coaxial cable.

In addition to the Glossary, you may find the following discussion of terms helpful.

MGX switches are called multiservice switches, because they can be used for multiple services, such as Asynchronous Transfer Mode (ATM) or Frame Relay (FR) transmissions. Each switch can also be used in different parts of a network. For example, the MGX 8950 can be at the core, the MGX 8850 (PXM45) can be used at the edge, the MGX 8850 (PXM1E) and MGX 8830 switches can do Private Network-to-Network Interface (PNNI) routing and function as feeders.

As of this printing, you can find information about the features of each switch in either of the following ways:

• Go to www.cisco.com and search for the switch name.

• Go to http://www.cisco.com/en/US/products/hw/switches/ps1938/index.html and click on “Cisco

MGX 8000 Series Switches”.

Chapter 1 Product Overviews

Processor Cards

MGX originally stood for media gateway switch, and over time, the MGX family has grown in speed, utility, and functionality as described throughout this guide.

Each MGX switch name is a trademark of Cisco (for example, Cisco MGX 8950). But for convenience, in this book, the switch name is often shortened (for example, MGX 8950).

Each MGX switch or gateway requires a processor switching module (PXM) controller card. Starting with Release 3, there were three models of MGX 8850 switches, so for clarity, the controller card was added to the MGX 8850 switch name, when applicable. For example, MGX 8850 (PXM1), MGX 8850 (PXM45), and MGX 8850 (PXM1E).

Table 1-2 shows the processor cards supported for each model of switch and the 8880 Media Gateway.

For documentation on Cisco MGX Release 1.x software and hardware, refer to

http://www.cisco.com/univercd/cc/td/doc/product/wanbu/mgx8850/index.htm.

Inside and outside of Cisco, several terms are often used for the same thing. Here are some examples:

• MGX switches contain printed circuit cards called front cards and back cards. Cards are also called

blades, modules, or boards. A controller card is sometimes simply called a controller. In this guide, the terms module is used for a front card and card is used for every other type of card.

• An interconnect device that enables redundant operation between cards is called a midplane, an

automatic protection switching (APS) backplane connector, or an APS connector. An additional type of connector that enables redundancy is a redundancy connector (RCON).

• Single-height slots can be converted to double-height slots by removing the center guide modules.

Center guide modules are also called center guides, midrail dividers, or service module slot divider assemblies. In this guide, the term center guide module is used.

• In the back of the switch, back cards go into bays. The upper bay is also called Bay 1, and the lower

bay is also called Bay 2. Figure 1-3 shows the bay and line numbers for an MGX 8850 switch.

• The MP port on the back of the PXM-UI-S3 user interface back card stands for maintenance port or

modem port. The CP port on the back of the PXM-UI-S3 user interface back card stands for control port or console port.

Narrow Band and Cell Bus Service Modules

A cell bus service module (CBSM) is an MGX service module that uses the MGX cell bus to transport customer traffic between that service module and other service modules or PXM uplinks. Traditionally, the CBSM cards were called narrow band service modules (NBSMs) because some AXSM cards (which use the MGX serial bus) support higher rate communications. AXSM cards run only in MGX 2 (and later) switches, and until MGX Release 3, the CBSM cards ran only in MGX 8850 (PXM1). So the purpose of the NBSM term was to collectively refer to all cards that ran in MGX 8850 (PXM1) and MGX

8820, because there were several types of these cards (for example AUSM, FRSM, CESM, and so forth). The serial bus service modules (AXSM and FRSM-12-T3E3) run only in MGX Release 2 and higher switches, hence the reason to differentiate between the two groups of cards.

Now that AXSM cards support narrow band rates and new CBSM cards are being developed for high-speed communications, the narrow- or wideband distinction is inappropriate and could be confusing. For example, one might think that a reference to NBSM cards includes the T1E1 AXSM cards because these cards support narrow band rates (AXSM cards use the serial bus). Although there are many differences between the AXSM and the CBSM, the port speed is no longer a clear differentiator. However, the bus used by AXSM cards and CBSM cards can be used to accurately differentiate between these two classes of cards.

Therefore, in this guide, CBSM is used to collectively refer to all the cards that use the cell bus for communications. Some CBSM cards run on the MGX 8850 (PXM1) and MGX 8820 products, and some are not supported on MGX Release 2 or have become obsolete.

Overview of Card Slot Assignments, by Chassis

As shown in Figure 1-3, the locations where the upper and lower back cards are installed are also called bays. On a Cisco MGX 8850 switch, a Cisco MGX 8950 switch, or a Cisco MGX 8880 Media Gateway, each slot has an upper and a lower bay for back cards.

Table 1-3 lists the valid slot numbers of the front cards (or modules) and back cards. Slot information is

listed by chassis.

Note The initial R- on some back cards means that this is a redundant back card, which is used for 1:N card

set redundancy without bulk distribution.

Caution The card and slot arrangements in Ta ble 1- 3 are called valid card installation options, because other

arrangements are not valid and can actually damage your chassis. For example, it is very important to insert the processor cards such as PXM45 or PXM1E into the correct slot for the switch!

MPSM Slot Assignments and MPSM Licensing

Consult your Cisco Customer Engineering representative for information about characterizing the quantity and placement of MPSM cards suitable for your network. For more information about MPSM licensing, see the the Release Notes for Cisco MGX 8850 (PXM1E/PXM45), Cisco MGX 8950, and Cisco

MGX 8830 Switches, Release 5.2.00.

Cisco MGX 8850 and MGX 8850/B Switches

The Cisco MGX 8850 (PXM45) multiservice switch was introduced in October 2000, on MGX Release

2.0. It used a PXM45 controller card.

Another MGX 8850 model was introduced in June 2002, on MGX Release 3.0.00. This model uses the new PXM1E controller card. Thus, starting with Release 3.0.00, for clarity, the controller card was added to the MGX 8850 switch name. For example, MGX 8850 (PXM45) and MGX 8850 (PXM1E). The MGX 8850 (PXM45) and MGX 8850 (PXM1E) switches look very similar.

Another model, the MGX 8850/B was introduced in January 2005. This model also has a PXM45 version and PXM1E version, depending on the controller card. Further, this switch supports 1:N redundancy with the support of a factory-installed redundancy connector card(s). Figure 1-4 is an illustration of an installed RCON in an MGX 8850/B.

MGX 8850 (PXM1E) and MGX 8850/B (PXM1E) Switch Overview

The PXM1E is a PNNI-enabled, double-height switch controller card that provides switching capabilities for use at the ATM network edge.

Service modules support communications between non-ATM services (such as Frame Relay and IP) and the ATM services on an ATM network. All network communications or customer traffic in and out of the switch goes through the service modules and route processor modules (RPMs). When a service module or RPM is combined with one or two back cards, a card set is created.

The MGX 8850 (PXM1E) and MGX 8850/B (PXM1E) switches support the following module types:

• ATM User-to-Network Interface (UNI) service module (AUSM)—Single-height front card

• Circuit emulation service module (CESM)—single-height front card

• Voice interworking service module (VISM)—single-height front card

MGX 8850 (PXM45) and MGX 8850/B (PXM45) Switch Overview

Note In this guide, PXM45, PXM45/B, and PXM45/C controller cards are identified collectively as PXM45,

unless otherwise specified.

The PXM45 controller card allows implementation of a complete range of narrow band services for high-density edge applications and broadband aggregation with 45 Gbps of nonblocking switching. The PXM45 can also be used exclusively for broadband aggregation and backbone functions.

Service modules support communications between non-ATM services and the ATM services on an ATM network. All network communications or customer traffic in and out of the switch goes through the service modules and RPM cards. When a service module or RPM is combined with a one or two back cards, a card set is created.

Chapter 1 Product Overviews

MGX 8850 and MGX 8850/B Card Compartment

The MGX 8850 and MGX 8850/B switches each have 32 single-height slots in a compartment card cage that holds cards and modules. Some single-height slots can be converted to double-height slots by removing the service module slot dividers.

Table 1-3 lists the cards supported in a MGX 8850 and MGX 8850/B switches. Abbreviated card names

are listed in the Glossary. (The initial R- on some back cards means that this is a redundant back card, which is used for 1:N card set redundancy without bulk distribution.)

Each slot on the front of the switch is numbered and has a corresponding slot located on the back of the switch. There are 32 front card slots and 32 back card slots. Slots 1 through 16 are in the top bay, and slots 17 through 32 are in the bottom bay of the switch.

Slot assignments and module support varies with the type of processor switching module you install in your switch (PXM1E or PXM45). The processor switching module allows service providers to deploy a complete set of services with up to 45 Gbps of nonblocking switching for low-density or remote deployments.

The following sections describe the supported cards and slot assignments for each type of processor switching module:

DC Power Entry Module

The MGX 8950 can accept power from a –48 VDC (–42 + –56 VDC) DC source that connects to one (primary) or two (secondary/redundant) –48 VDC PEMs. Each primary or redundant DC source connects to one DC PEM in the system. Each DC PEM accepts two 100 A service feeds from the same DC source. Figure 1-28 shows a close-up of the DC PEM.
