| LANplex 2500
The LANplex 2500 Ethernet/FDDI switch offers unparalleled
price/performance with ISE-chip technology that can speed throughput
to more than 562,000 packets per second. The switch accommodates one
or two 8-port Ethernet modules and up to two single-port FDDI/CDDI
modules. Modules are available with all types of media connections.
High-speed modules for 100BASE-T Fast Ethernet and ATM will be
available in the future.
With the LANplex 2500, you can:
* Boost performance where it's needed with full-wire-speed
forwarding on all switched ports for all configurations- no
exceptions
* Set up high-speed connections to eliminate traffic bottlenecks to
file servers and the backbone
* Prepare the way for migration to higher-speed technologies with a
future-proof platform
* Maximize uptime with redundant power and hot-swappable modules
Full-Featured Intelligent Switching
* Elastic Packet Buffering prevents port congestion and minimizes
dropped packets when traffic is heavy
* Packet filtering lets you control traffic flow based on
characteristics you define, including multicast traffic, protocol
type, or MAC address
* You can configure thresholds to control multicast/broadcast
storms, with the filters based on any packet attribute
* IP Fragmentation allows FDDI packets greater than 1518 bytes to be
forwarded to stations on an Ethernet segment. This technique also
lets FDDI stations communicate most efficiently with each other
using maximum size (4500-byte) packets
Express Switching, Bridging, and Intranetwork Routing
* Express Switching simplifies address learning and reduces packet
flooding
* IEEE 802.1d Bridging mode optimizes Ethernet links for larger
networks by providing full address learning
* Intranetwork IP routing supports multi-ple switched segments per
subnet and multiple subnets per port. Routing may be enabled on a
per-port basis
High-Speed Server and Backbone Links
* The switch can be equipped with up to two switched FDDI ports,
delivering high-bandwidth connections to file servers and/or an
FDDI backbone
* The switch's ASIC-based ISE-chip architecture will support other
high-performance technologies implemented on future modules
Media Flexibility
The LANplex 2500 supports a wide range of media connections:
* 10BASE-T (RJ-45)
* 10BASE-T (RJ-21, 50-pin telco)
* 10BASE-FL (FOIRL)
* 10BASE2 (BNC)
* 10BASE5 (AUI)
* FDDI Fiber DAS
* FDDI twisted-pair DAS (TP-DDI)
The dual-attach (DAS) connectors allow you to add resiliency in case
of FDDI ring failure. Also, DAS ports may be used for 2
single-attached connections.
Powerful System Management
* Virtual LAN capability gives you more flexibility in designing and
managing your network, allowing you to define virtual workgroups
independent of physical connections
* FDDI SNMP support include FDDI SMT (Station Management) Revision
7.3 and an SNMP/FDDI SMT proxy that allows management of all the
FDDI stations
* The switch supports MIB II, Ethernet MIB, FDDI SMT 7.3 MIB, Bridge
MIB, SNMP/FDDI MIB, and LANplex management MIBs
* Software updates can be downloaded via in-band and out-of-band
networks using ftp
Uptime Assurance
* The ASIC-based switching architecture reduces component count and
opera-tional complexity, increasing reliability
* An optional redundant power supply provides a complete backup for
the power unit in each switch

| LANplex 2016
The LANplex 2016 provides up to 16 switched Ethernet ports using the
same Ethernet switching modules as the LANplex 2500. It incorporates
ISE-chip technology and most of the advanced Ethernet switching
features found in the LANplex 2500. The same reliability features are
also offered, including hot-swappable modules and an optional
redundant power supply.
With the LANplex 2016, you can:
* Enhance bandwidth in workgroups and small departments with
full-rate switching on all ports
* Benefit from high-end switching per-formance, flexibility, and
reliability in an economical platform
* Manage with the full range of administrative features available
for the LANplex family of products
* Maximize uptime with redundant power and hot-swappable modules
Robust Switching and Management
* The switch provides packet filtering, virtual LAN support, and a
choice of Express Switching or IEEE 802.1d Bridging for
exceptional switching flexibility and control
* You can manage the switch using all the capabilities of the
LANplex/Transcend Administration Console. It also supports a full
complement of SNMP MIBs as well as 3Com's Transcend Enterprise
Manager for UNIX applications
Media Flexibility
The LANplex 2016 supports a range of Ethernet media:
* 10BASE-T (RJ-45)
* 10BASE-T (RJ-21, 50-pin telco)
* 10BASE-FL (FOIRL)
* 10BASE2 (BNC)
* 10BASE5 (AUI)
