Introduction

Switch Architecture

These switches employ a wire-speed, non-blocking switching fabric. This permits

simultaneous wire-speed transport of multiple packets at low latency on all ports.

These switches also features full-duplex capability on all ports, which effectively

doubles the bandwidth of each connection.

These switches use store-and-forward switching to ensure maximum data integrity.

With store-and-forward switching, the entire packet must be received into a buffer

and checked for validity before being forwarded. This prevents errors from being

propagated throughout the network.

Description of Hardware

10/100/1000BASE-T Ports

These switches contain 16/24 RJ-45 ports that operate at 10 Mbps or 100 Mbps, half

or full duplex, or 1000 Mbps, full duplex. Because all ports on both switches support

automatic MDI/MDI-X operation, you can use straight-through cables for all network

connections to PCs or servers, or to other switches or hubs. (See “10BASE-T/

100BASE-TX Pin Assignments” on page B-1.)

Each of these ports support auto-negotiation, so the optimum transmission mode

(half or full duplex), and data rate (10, 100, or 1000 Mbps) can be selected

automatically.

Each port also supports auto-negotiation of flow control, so the switch can

automatically prevent port buffers from becoming saturated.
