Enterasys X-Pedition 8000/8600 Getting Started Guide 21
Hardware Overview
SSR-ARE
The Advanced Routing Engine (ARE) provides the X-Pedition 8000/8600 an avenue for routing
protocols other than IP and IPX—currently, the ARE supports only the Appletalk protocol. The
ARE is powered by a RISC processor that operates at 380Mhz, providing lightning-fast routing of
your personal appletalk traffic. If you use a VLAN to create an AppleTalk interface, you must use
an AppleTalk procotol-based VLAN.
Note: The ARE module cannot be installed into slots 0 or 1 on an X-Pedition 8000, or 0, 1, or 15
on an X-Pedition 8600. Attempting to hot swap this module into any of those slots may
cause the router to core dump.
SSR-ATM29-02
The fully integrated design of the X-Pedition family increases the value of the product line by
providing a seamless solution to support the industry’s most complete range of technology and
media options. This scalable framework ensures full cross-platform compatibility and allows for
the smoothest possible migration as customers’ technology and interface requirements evolve.
The combination of the X-Pedition and the SSR-ATM29-02 OC-3c module provide a complete
solution for both the service provider and enterprise markets. Interconnecting IP networks over an
ATM backbone is done by many service provider and enterprise customers. The OC-3c module
provides the vital link between the network’s switch-router solutions and the ATM-based solution
in the WAN. Each PVC on the module can be configured as a routed IP interface, and the ATM
backbone can provide connectivity from one routed backbone to another.
The SSR-ATM29-02 is a modular, high-performance OC-3c ATM interface for the
X-Pedition 8000 and X-Pedition 8600. The module is optimized to provide an ATM uplink to an
ATM backbone, and supports two modular slots, each of which accepts T1/E1, T3/E3 and OC-3c
(single mode and multimode fiber, as well as unshielded twisted pair) interface.
The SSR-ATM29-02 line card actually houses various Physical Layer (PHY) interface cards in its
two available slots. ATM PHY cards provide the media-specific portion of an ATM interface to
support ATM connectivity across multiple platforms using different media types. The host system
provides the power, initialization, and control for the PHY card. The PHY card is used with an
ATM segmentation and reassembly (SAR) or cell-switching function.
See Installing the ATM PHY Cards on page 80 for installation instructions for the ATM PHY cards
into the SSR-ATM29-02 line card. Figure 9 shows the front panel of the SSR-ATM29-02 line card.
