Cisco MGX 8800/8900 Series Hardware Installation Guide
Releases 2 - 5.2, Part Number OL-4545-01, Rev. H0, May 2006
Chapter 2 Illustrated Card List for MGX Switches and the MGX 8880 Media Gateway
Front Cards
• Provides Cisco IOS-based multiprotocol routing over ATM and ATM interface Layer 3 termination,
local server interconnect over high-speed LANs, access concentration, and switching between
Ethernet LANs and the WAN interfaces of the Cisco MGX switch or gateway.
• Provides forwarding technology for packet switching capabilities in excess of 2 million pps. The
forwarding engine is packet-based and is interfaced to the midplane of the system through a
combination of switch interface technologies.
• Provides Cisco IOS router services and also provides ATM connectivity to the Cisco MGX switch
serial interface at full-duplex OC-24.
• Uses an RM7000A MIPS processor, a parallel packet processing engine, an integrated ATM
interface, and a serial interface ASIC to interface with the Cisco MGX switch serial
interface controllers.
When an RPM-XF is combined with a high-speed uplink back card and a management back card, a card
set is created. The RPM-XF card set consists of the RPM-XF-512 and the following back cards:
• MGX-XF-UI—A management back card that is always installed in the lower rear bay back slot
directly behind the RPM-XF
• MGX-XF-UI/B—A “notched” management back card that is installed in rear bay. It fits into the
RCON of the MGX 8880 Media Gateway, directly behind the RPM-XF
• MGX-1OC12POS-IR or MGX-1GE—A back card that is always installed in the upper rear bay back
slot directly behind the RPM-XF
The MGX-1GE must have one of the following SFP transceivers installed on it:
• MGX-GE-LHLX (1000base-LH/LX SFP single-mode, standardized for MGX)
• MGX-GE-SX (1000base-SX SFP multimode, standardized for MGX)
• MGX-GE-ZX (1000base-ZX SFP single-mode, standardized for MGX)
Note Back cards are optional with the RPM-XF card.
Note For information on RPM-XF software features and configurations, refer to the Cisco MGX Route
Processor Module (RPM-XF) Installation and Configuration Guide, Release 5.2. For technical
specifications for the RPM-XF cards, see the “RPM-XF Specifications” section on page A-8.
