Product Information
High performance, convergence-ready, 10/100/1000 Module with PoE Support
This module delivers 48 ports of high-performance 10/100/1000 Mbps Ethernet
switching and Power over Ethernet (PoE) distribution over Category 5
twisted-pair copper cable.
3Com Switch 7700 modules support on-board or local Layer 2 switching,
allowing packets to remain local to the module, which reduces backplane and
switch fabric loading. This reduces congestion in the network, minimizing
packet loss, to help enable applications to run faster across the network.
The reduction in latencies will help improve the quality of video and voice
traffic across the network.
48 ports of in-line power 10/100/1000 connectivity, for data switching and
PoE distribution using the same cabling.
Local Layer 2 switching at 16Gbps between ports on the same module.
Each module added to a chassis increases total switch performance; for
example, six of these modules, when added to a Switch 7700 7-slot or 8-slot
chassis, provides 240 Gbps switching performance.
Interface transmission rates: 1Gbps (full duplex).
Supports IEEE 802.3z, IEEE 802.3x, IEEE 802.3ad, IEEE 802.1p, IEEE 802.1D,
IEEE 802.1Q, IEEE 802.3af.
3Com Switch 775X External PoE Power Rack, purchased separately, provisions
the power needed to be distributed by this module.
Power over Ethernet in the 3Com Switch 7700 family is supported only by the
3Com Switch 7757 7-Slot and Switch 7754 4-Slot Chassis.
