SuperStack II Switch 1100 and SuperStack II Switch 3300 
Optional High-Speed Accessories

The SuperStack II Switch matrix module
and matrix cable let you mix and match
SuperStack II Switch 1100s and 3300s 
to improve throughput, share downlinks,
and ease management. Use the matrix
cable to connect two Switch 1100s or
Switch 3300s and the matrix module 
to connect up to four switches* while
conserving Fast Ethernet ports. The
matrix module’s 4 x 1 Gbps backplane
provides a 1 Gbps link between switches.
Ultralow latency (maximum 300
nanoseconds) and hardware flow control
ensure top performance at low cost. The
entire stack can be managed as a single
entity.

■

Any switch port can be configured 
to support roving analysis across the
stack for greater visibility into traffic
flows and RMON data; the module
supports IEEE 802.1D and 802.1Q
standards for VLANs and Ethernet
Class of Service (CoS).

*Each unit in a stack requires a matrix cable,
including the unit that holds the matrix module.

The SuperStack II Switch 100BASE-FX
module adds a fiber Fast Ethernet back-
bone link to your switched workgroup.
The easy-to-install dual module is an
excellent choice for resilient connections
in mission-critical networks or when
multiple fiber backbone connections are
needed to and from the stack. A single
high-speed backbone link can be shared
by multiple units in a stack.

■

Full-duplex Fast Ethernet 

provides 200 Mbps throughput 
and 2 kilometers distance on fiber.

The SuperStack II Switch Gigabit Eth-
ernet modules support high-
performance, fault-tolerant interwork-
group and workgroup-to-backbone
connections.The easy-to-install modules
provide full-duplex Gigabit Ethernet up
to 2 Gbps throughput, eliminating net-
work bottlenecks.They support both
802.1D spanning tree and resilient links.

■

The SuperStack II Switch 1000BASE-

SX module offers a multimode fiber
interface over distances up to 550
meters (for 50 micron for MMF).

■

The SuperStack II Switch 1000BASE-

LX module offers multimode and
single-mode fiber interfaces over dis-
tances certified by 3Com up to 10
kilometers.

■

The SuperStack II Switch 1000BASE-T

module offers a Category 5 copper
interface over distances up to 100
meters.
