PRODUCT OVERVIEW

Product Overview The 3Com Switch 8800 Family Series Routing Switches (hereinafter referred to as

Switch 8800 Family series) are a series of large capacity, modularized L2/L3

switches. They are mainly designed for broadband MAN, backbone, switching

core and convergence center of large-sized enterprise network and campus

network. They provide diverse services and can be used in constructing stable and

high-performance IP network. The series include the following main models:

■ Switch 8807 routing switch

■ Switch 8810 routing switch

■ Switch 8814 routing switch

Switch 8800 Family series use integrated chassis, which can be subdivided into

power supply area, module area, backplane and fan area.

For Switch 8807, in the module area, there are seven slots: the top two (slot0,

slot1) accommodate fabric modules, which are in 1+1 redundancy; the remaining

five accommodate I/O Modules.

For Switch 8810, in the module area, there are 10 slots: the two (slot4, slot5) in

the middle accommodate fabric modules, which are in 1+1 redundancy; the

remaining 8 accommodate I/O Modules.

For Switch 8814, in the module area, there are 14 slots: the two (slot6, slot7) in

the middle accommodate fabric modules, which are in 1+1 redundancy; the

remaining 12 accommodate I/O Modules, which can be hybrid. For specific

configurations of the hybrid modules, refer to the "BGP/MPLS VPN Configuration"

section of the MPLS module.

Switch 8800 Family series support the following services:

■ Internet broadband access

■ MAN, enterprise/campus networking

■ Providing multicast service and multicast routing and supporting multicast

audio and video services.
