SWITCH 7700 FAMILY DATA SHEET

The 3Com
®
Switch 7700 modular LAN switch
family delivers high-performance, multilayer,
10-Gigabit, Gigabit, and Fast Ethernet switching
and routing in a scalable, flexible, modular
chassis. Three chassis configurations are
offered:
• High-availability 8-slot redundant chassis,
w
ith six payload slots, primary switch
fabric, and optional backup switch fabric.
• 7-slot, with six payload slots plus switch
fabric.
• 4-slot, with three payload slots and switch
fabric.
The resilient systems architecture helps
provide business network continuity for
data and voice convergence applications—
required in demanding core and campus
environments.
The 3Com Switch 7700 is ideal for campus and
building-level switching in the core or distri-
bution of the network, with support for up to
six 10-Gigabit or 288 Gigabit ports. Power over
Ethernet (PoE) support in two chassis—Switch
7757 and 7754—and 48-port PoE Gigabit and
Fast Ethernet modules make the Switch 7700
ideal for edge installations.
The Switch 7708R 8-Slot chassis is designed
for networking environments demanding the
highest level of resiliency. When configured
with an optional spare switch fabric, the
Switch 7708R boasts sub-one-second switch
fabric failover should there be a primary
fabric failure, helping ensure continuous
network operation.
Fault-tolerant aggregation features in the
Switch 7700 f
amily include
V
irtual Router
Redundancy Protocol (VRRP), Rapid Spanning
Tree Protocol (RSTP), Spanning Tree Protocol
(STP), Multiple Spanning T
r
ee Pr
otocol
(MSTP), and link aggregation for virtually
non-stop network availability. The architecture
of the Switch 7700 supports a passive
backplane and N+1 redundant power
su
pplies for seamless network operation.
The Switch 7700 family supports IP
(RIP, OSPF
†
), IPX
†
, and IGMP PIM (DM
and SM) multicast routing for logical
network segmentation and traffic
control. Advanced QoS features provide
differentiated network services for traffic
classification and prioritization based on
D
iffserv Code point, Type of Service (ToS),
and IEEE 802.1p Class of Service (CoS).
Advanced Bandwidth management allows
different traffic flows to be shaped using
packet priority, minimum and maximum
bandwidth thresholds, and individual flow
weightings.
These features enable optimal priority
queuing of network data, helping to ensure
minimal congestion for important traffic.
Routing in hardware of multicast traffic for
voice and video streaming enables minimal
latencies through the switch.
The network can be secured from unautho-
rized access through IEEE 802.1X RADIUS
Network Login, Access Control Lists and
management authentication. The chassis
supports most cabling requirements and
offers comprehensive management for simple
configuration and advanced network
monitoring and troubleshooting.
The 96 Gbps switch fabric supports four SFP-
based ports for additional Gigabit copper or
fiber connections. This is particularly
helpful when Gigabit ports are required for
an uplink, and the payload slots contain Fast
Ethernet modules.

Power over Ethernet
N
ew to the 3Com Switch 7700 family are two
chassis with IEEE 802.3af standard Power
over Ethernet (PoE) support. These chassis
have been designated 775X to distinguish
them from the earlier 770X chassis. The
Switch 7757 chassis is a PoE-ready 7-slot
chassis while the 7754 is a 4-slot PoE-ready
chassis.
