RCHITECTURE
The switch employs a wire-speed, non-blocking switching fabric. This permits
simultaneous wire-speed transport of multiple packets at low latency on all
ports. The switch also features full-duplex capability on all ports, which
effectively doubles the bandwidth of each connection.
The switch uses 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.

PTIONS
With a comprehensive array of LEDs, the switch provides “at a glance”
monitoring of network and port status. The switch can be managed over the
network with a web browser.
For a detailed description of the management features, refer to the Management
Guide.

The switch contains 24 RJ-45 ports that operate at 10 Mbps or 100 Mbps, half or
full duplex, and 1000 Mbps full duplex. Because all ports on the switch 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
"1000BASE-T Cable Requirements" on page 47 .)
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. If a device connected to one of these ports does not
support auto-negotiation, the communication mode of that port can be
configured manually.
Each port also supports IEEE 802.3x auto-negotiation of flow control, so the
switch can automatically prevent port buffers from becoming saturated.
