Switch 9300 Intelligent Switch
The SuperStack II Switch 9300 family delivers full line
rate, nonblocking switching among all 12 Gigabit
Ethernet ports. The three models give you options for
using multimode (MMF) or single-mode (SMF) fiber:
■
3C93010 — 12 1000BASE-LX ports (MMF or SMF)
for fiber with SC connectors. See Figure 1.
■
3C93011 — 10 1000BASE-SX (MMF) ports plus 2
1000BASE-LX ports (MMF or SMF) for fiber with
SC connectors. See Figure 2.
■
3C93012 — 12 1000BASE-SX ports (MMF) for
fiber with SC connectors. See Figure 1.
The Switch 9300 supports full-duplex mode on all
Gigabit Ethernet ports and up to 16,000 MAC
addresses. To deliver even higher performance rates
among switches, the Switch 9300 supports trunking,
which allows combining up to six Gigabit Ethernet
ports into a single multigigabit connection.
System Features and Benefits
The Switch 9300 is part of 3Com’s SuperStack family.
To combine technologies as your network grows,
install the Switch 9300 in a SuperStack network.
Some key features of the Switch 9300 system:
■
High-density Gigabit Ethernet configuration
The SuperStack II Switch 9300 exhibits no packet
loss or delays even under maximum network traffic
on its 12 Gigabit Ethernet ports.
■
Trunking of Gigabit Ethernet ports
The Switch 9300 allows you to choose
performance-level links between switches, with up
to 6 Gigabits of bandwidth.
■
Resilient Links
Resilient links protect your network against an
individual link or device failure by providing a
secondary backup link that is inactive until needed.
■
Trunking links, Spanning Tree Protocol, and
Advanced Redundant Power System (RPS) support
The Switch 9300 protects against cable and
equipment failures with Spanning Tree Protocol
and trunking links. The SuperStack II Advanced RPS
protects against power interruptions for
fault-tolerant networks. See Figure 3.
