SWITCH 7750 FAMILY
Highly flexible, resilient architecture for end-to-end enterprise deployment
in the core, data center, distribution layer and network edge.
High-density multilayer switching for Fast Ethernet, Gigabit Ethernet and
10-Gigabit Ethernet.
Up to 288 Fast Ethernet or 292 Gigabit Ethernet ports per system.
10-Gigabit uplinks for ultra-high-speed backbone connectivity.
Up to 240 Gbps system bandwidth; up to 179 Mpps switching capacity.
Advanced traffic prioritization and routing of multicast traffic in hardware
for convergent applications including VoIP, streaming audio and video.
Virtually non-stop operation with redundant power supplies, fans and
switch fabrics*, as well as hot-swappable switching I/O modules.
Robust network access control and enterprise-wide security via standards-
based IEEE 802.1X, RADIUS Authenticated Device Access (RADA), and
advanced Access Control Lists; authentication and encryption of manage-
ment traffic via SSH v2 and SNMP v3.
Industry-standard PoE to power IP phones, wireless access points and
other devices; reduces implementation and maintenance costs.
Unified management and administration with a common operating system
and centralized control available via 3Com Enterprise Management Suite.
Granular QoS and traffic management for enhanced availability and
performance of critical business applications.
Extensive L2/3/4 switching and routing capability, including advanced
features like IS-IS
†
and BGP-4
†
, applicable in very large enterprises. IPX
routing for enhanced support of legacy environments.
* Redundant fabric available on Switch 7758 only.
†
Available in the 3Com Advanced Feature Software, at additional cost.
