Several forces are driving the need for high speed LANs today - The growth of the Internet, re-centralization of
corporate computing, and network-centric applications. Applications today such as transaction processing, voice,
video, graphics, and Internet access are bandwidth consuming, server-oriented, and require higher speed networks.
They demand high performance and ready availability for the desktop user.

The Compaq SW5425 Desktop Gigabit Ethernet Switch is poised to meet these demanding needs at the desktop with
Gigabit switching capability. Users can employ the 24 10Base-T/100Base-TX ports that autosense for 10/100 Mbps
operation and half- or full-duplex operation. The single Gigabit Ethernet port can accommodate high performance
applications with fail-over achieved through the redundant port. The SW5425 switch is capable of non-blocking, line
rate performance on all ports when configured as a Layer 2 switch or as a Layer 3 IP router.

EASE OF USE

Auto-negotiation

Each RJ-45 switched port on the Compaq SW5425 automatically senses if it is a 10 Mbps or a 100 Mbps network
connection, thus allowing for seamless communication among the Ethernet family of protocols.

Hot-swappable Gigabit Interface Connector

The standard Gigabit Ethernet port, a hot-swappable 850nm 1000Base-SX GBIC module, can be replaced with a
1000Base-LX GBIC for networks spanning longer distances.

PER FORMANCE

More Power

A massive backplane provides more than enough raw bandwidth to support non-blocking operation. This means that
all ports transmit and receive traffic at line rate (full-duplex operation) without over-subscribing the switch.

Dynamically assigned buffer memory (2 MB) ensures that even during peak traffic conditions no data is lost.

Load Sharing/Port Aggregation

The Compaq SW5425 can be configured to use a group of ports to carry traffic in parallel between switches. This
creates higher throughput and resilience.

Quality of Service (QoS)

QoS dedicates bandwidth to traffic types, allowing network managers to shape network traffic and provide needed
bandwidth to business-critical applications.

NET WORK MANAGEMENT

Compaq Networking Management Software (CNMS)

CNMS provides an intuitive graphical user interface making installation and monitoring of the Compaq SW5425
effortless.

Easy to use TELNET and Web-based management are provided for hands-on management and configuration. The
Compaq SW5425 can be graphically managed under powerful management platforms such as HP OpenView, IBM
NetView, SunNet Manager, and Novell ManageWise using WinManager, a product from Compaq partner Ordinox
Networks.

Remote Monitoring (RMON) Groups 1 , 2, 3, 9

The SW5425 supports four of the nine groups of remote monitoring — network traffic statistics, history, alarms, and
events.

Virtual LANs (VLANs)

Setting up VLANs eases many time-consuming ta sks of network administration while increasing efficiency in network
operations. By tagging each frame with information about which virtual LAN it belongs to, users can be connected to
any LAN segment regardless of their physical location. The SW5425 uses the IEEE 802.1Q draft standard and
supports up to 256 VLANs. The switch also supports protocol and port based VLANs that are not covered in the
standard

With this capability, the network manager can configure the switch to copy all traffic associated with one or more ports
to a monitor port on the switch. The monitor port can be connected to a protocol analyzer or RMON probe for network
traffic analysis and connection integrity.

SECUR ITY/RELIABILITY

Spanning Tree Protocol

The IEEE 802.1D spanning tree protocol provides fault tolerance by allowing the user to implement parallel paths for
network traffic. Redundant paths are disabled when the main paths are operational and enabled if the main path fails.

Redundancy (Fault Tolerance)

One redundant Gigabit Ethernet port is included for fast failover for the active Gigabit port. If the active port fails or
loses link status, the switch automatically activates the redundant port. An optional redundant power supply can also
be purchased.

Routing Standards Compliance

SW5425 supports Open Shortest Path First (OSPF), Routing Information Protocol (RIP), and RIP v2, ensuring
interoperability between other Compaq switches and legacy routers.

This allows network managers to build fault-tolerant meshed topologies that eliminate single points of failure and avoid
network downtime.

Worldwide Leader in Total Cost of Ownership

Integrated management, guaranteed Ethernet and Fast Ethernet inter-operability, single source of support, and strong
service and support options provide Compaq customers with a lower total cost of ownership (TCO), a higher level of
network reliability, and greater confidence.

Designed with quality and long life in mind, the Compaq SW5425 meets all of Compaq’s high design and
manufacturing standards. Surface-mount technology, ASIC-based hardware, state-of-the-art manufacturing facilities,
and top-notch quality inspection provide the reliability and quality expected from a Compaq product.
