SWITCHINGDATA SHEETOVERVIEWThe 3Com® Switch S7900E family is the nextgeneration of modern multilayer switches that meetthe evolving needs of integrated service networks.The S7900E family consists of six chassis models:S7910E (12 slots), S7906E (8 slots), S7906E-V(8 vertical slots), S7903E (5 slots), S7902E (4 slots)and S7903E-S (3 slots).The platform uses modern ASICs and high speedbackplanes for long term investment protection.All models have passive backplanes and support loadsharing and redundant management and fabrics forhigh availability (except the S7903E-S with a singlefabric for cost-effective solution). The S7900E can bedeployed in multiple network environments, such as;enterprise LAN core, aggregation and wiring closetedge as well convergence and edge of MetropolitanArea Networks (MANs), The S7900E provides thelatest distributed ASIC switching technology enablingwire-speed Layer 2 and Layer 3 routing services forthe most demanding applications.The S7900E supports high reliability technologiessuch as non-stop forwarding (NSF), and ring networkprotection. By improving productivity and ensuringmaximum up time, the S7900E can reduce total cost ofownership (TCO). The S7900E family is environmentallyfriendly, meeting the Restriction of the Use of CertainHazardous Substances in Electrical and ElectronicEquipment (RoHS) standards.KEY BENEFITSMODERN ARCHITECTUREThe S7900E chassis has been designed to allow forlong term investment protection. The backplanetraces will allow for higher performance in the future.Intelligent power and environmental managementmake these changes possible. The system uses a newgeneration of more energy efficient merchant silicon,with future support for emerging standards. This willallow the implementation of new features in thefuture, as they become available. With a choice of sixdifferent chassis, users have increased configurationflexibility. Fabrics and modules can be used across allchassis.EXTENSIVE FEATURE LISTThe S7900E provides all the features expected in a highend modular chassis used for demanding enterprisecore, distribution and aggregation applications. Itsupports wire-speed communications at layer 2 andfor IPv4 and IPv6 as well as MPLS services.› Separate data and control paths for added securityand performance› Extensive Quality of Service (QoS) features formission critical applications including Voice over IP(VoIP), storage and video› Comprehensive security for network access control,encryption and protection of corporate resources.> Extensive high availability capabilities and the abilityto create a resilient virtual switching fabric usingIRF™ (Intelligent Resilient Framework) technology.3COM SWITCHS7900E FAMILYSWITCHINGDATA SHEETFront left to right S7902E, S7903E-S.
