The 3COM 3CR17450-91 you're interested in is a: Highly featured, stackable managed Gigabit Ethernet switching with 10Gbps expansion slot and Layer 3-capable hardware; 24 ports.
Stackable Managed Gigabit Switching
For Enterprise
Ethernet networks needing a scalable, stackable, future-proof Gigabit switching
solution, the 3Com® SuperStack® 3 Switch 3870 24-Port is recommended.
It
is ideal for Gigabit to the desktop applications in high performance workgroups.
As the basis for a future-proof Enterprise workgroup environment, with
compatibility with slower desktop connections, it can be the platform to support
a gradual move to Gigabit speeds.
This 24-port 10/100/1000 Gigabit
Ethernet switch combines wirespeed Layer 2 switching with stackability up to
eight units high via a 40Gbps stacking architecture for impressive scalability—
to 384 ports total. The hardware supports a 10-Gigabit expansion slot and is
Layer 3-capable for investment protection.
Twenty-four auto-sensing
10/100/1000 copper ports provide flexible desktop and workgroup attachments,
which can ease migration for environments with a mix of 10/100 and
Gigabit-enabled desktops and servers. Four dual-purpose slots support SFPs that
can connect to fiber cabling for flexible Gigabit Ethernet backbone and server
connections.
Resiliency features such as IEEE 802.1w Rapid Spanning Tree
Protocol and IEEE 802.3ad link aggregation (LACP) across stacked units helps
ensure uptime and availability. Enterprise-class security features include IEEE
802.1X network login, SSH/SSL encrypted device log-in, and access control lists.
24 auto-negotiating 10/100/1000 ports for seamless migration from Ethernet
or Fast Ethernet to Gigabit Ethernet (48-port
model also available)
Integrated dual 10Gbps full duplex stacking ports— 40Gbps total stacking
bandwidth— for stacking of up to eight units high
Wirespeed, with forwarding rates up to 80 million pps, and a switching
capacity of 108 Gbps
Includes four dual-purpose ports, supporting SFP slots to accommodate 1000BASE-SX,
1000BASE-LX,
and 1000BASE-LH
connectivity
Up to 32 trunks of eight ports each can be configured using IEEE 802.3ad
