3COM® SWITCH S7900EFAMILY

A modern high-performance modular switching androuting platform for the demanding enterpriseenvironment, supporting highly available, secure andconverged business applications

OVERVIEWThe 3Com® Switch S7900E Family is the next generation of multi-layer switches, meeting theevolving needs of integrated service networks.

This switch can be deployed in multiple network environments like the enterprise LAN core,aggregation and wiring closet edge, as well the convergence and edge of Metropolitan AreaNetworks (MANs).

A passive backplane and support for load sharing and redundant management and fabrics helps theSwitch S7900E offer high availability. With modern ASICs, high-speed backplanes and the latestdistributed ASIC switching technology, this switch delivers wire speed Layer 2 and Layer 3 routingservices for the most demanding applications, while providing long term investment protection.

Supporting high-reliability technologies such as non-stop forwarding (NSF) and ring networkprotection, the Switch S7900E helps ensure maximum uptime, improving productivity andreducing the total cost of ownership. This switch family is environmentally friendly, meeting theRestriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment(RoHS) standards.

The 3Com Switch S7900E Family features five available chassis models, providing flexibilitybased on the switching capacity and interface port density required:

› Switch S7910E with 12 slots,› Switch S7906E with eight slots,› Switch S7906E-V with eight vertical slots,

› Switch S7903E with five slots, and the› Switch S7902E with four slots.

KEY BENEFITSMODERN ARCHITECTUREThe Switch S7900E chassis has been designed to allow forlong term investment protection. The backplane traces willallow for higher bandwidth and increased power in the future.Intelligent power and environmental management makethese changes possible. The system uses a new generation ofASICs, with the ability to support emerging standards. Thesenew ASICs are also more energy efficient. With a choice of fivedifferent chassis, users have increased configurationflexibility. Fabrics and modules can be used across all chassis.

EXTENSIVE FEATURE LISTThe Switch S7900E provides all the features expected in ahigh-end modular chassis used for demanding Enterprisecore, distribution and aggregation applications:› separate data and control paths for added security and

performances

› extensive Quality of Service (QoS) features for missioncritical applications including Voice over IP (VoIP), storageand video

› comprehensive security for network access control,encryption and protection of corporate resources

› extensive CLI capabilities, with available GUI

› an open, standards-based architecture to enable seamlessgrowth and future investments without proprietary lock-ins.

RESILIENT ARCHITECTURE FOR BUSINESSCONTINUITYThe Switch S7900E has a high-availability design includingpassive backplane, load sharing fabrics and managementmodules and redundant power supplies. All elements in thesystem can be hot-swapped, minimizing the impact of singlecomponent failure. Changes in network topology due to deviceor link failures can lead to disruption of service for criticalbusiness applications. Rapid recovery from such topologychanges is achieved with features such as Multiple SpanningTree Protocol (MSTP), Rapid Spanning Tree Protocol (RSTP),OSPF Equal Cost Multi Path (ECMP) and Virtual RouterRedundancy Protocol (VRRP).

The 3Com Switch S7900E also supports Rapid Ring ProtectionProtocol (RRPP), which allows the creation of fast recoveryrings using standard Ethernet technology.

SUPPORT OF CONVERGENCEReal-time applications such as VoIP demand high QoS anddifferentiated service levels to function properly. The SwitchS7900E provides robust QoS and advanced traffic managementfeatures, allowing critical applications to be prioritized andserviced as dictated by the needs of the organization.

Additionally, this switch supports industry-standard IEEE802.3af Power over Ethernet (PoE) to provide both electricalpower and network connectivity to PoE-capable devices suchas IP telephones and wireless access points, making theswitches ideal for large-scale edge deployments. PoEsimplifies network deployments by eliminating the need forseparate data and power infrastructures.

The Switch S7900E supports flexible PoE solutions includinghybrid power supplies providing both data and power.

EXTENSIVE SECURITY FEATURESSecurity is paramount in today’s enterprise. The 3Com SwitchS7900E delivers advanced security including user and deviceauthentication, policy-based access control lists (ACLs),encrypted protocol headers and system management access.The switch supports IEEE 802.1X Network Login along withRADIUS to allow user access control. Port, VLAN and MACaddress authentication allow for additional security.

SCALABLE PERFORMANCEThe 3Com Switch S7900E has a 2.4 Tbps backplane, providingenhanced performance and future expansion capability. Withdual fabrics, the switch delivers up to 488 Mpps throughput.A wide selection of modules allow a single switch to supportup to 24 10-Gigabit and 480 Gigabit and Fast Ethernet ports.Flexible modules combine 10-Gigabit and Gigabit in a singlemodule. All fiber-based Gigabit modules support both100BASE-FX and 1000BASE-X transceivers.

Standards-based link aggregation—supported acrossmodules—allows aggregating multiple links together as a trunk.

ENTERPRISE CLASS MANAGEMENTThe Switch S7900E features independent data and control paths.The dedicated data channel provides high-speed data switchingand packet forwarding, while a separate management channelprovides control, monitoring, route learning and distribution.

Comprehensive management features allows the switchto provide enterprise-wide visibility and control to IT stafffor configuration, network monitoring and advancedtroubleshooting. Switch management is accessible throughan industry standard CLI, an intuitive GUI, a Web-basedinterface, or SNMP, with hierarchical access controls andpassword protection.

Additional switch management security is provided throughthe user authentication and encryption capabilities of SNMPv3 and SSH v2, further reducing the likelihood of unauthorizedaccess or snooping of management traffic.
