RCHITECTURE
These Gigabit Ethernet switches employ a wire-speed, non-blocking switching
fabric. This permits simultaneous wire-speed transport of multiple packets at low
latency on all ports. The switches also feature full-duplex capability on all ports,
which effectively doubles the bandwidth of each connection.
For communications between different VLANs, these switches use IP routing. For
communications within the same VLAN, they 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.
These switches include built-in stacking ports that enable up to eight units to be
connected together through a 48 Gbps stack backplane. The switch stack can be
managed from a master unit using a single IP address.
These switches also include two slots on the rear panel for slide-in single-port
10GBASE modules.

PTIONS
These switches contain a comprehensive array of LEDs for “at-a-glance”
monitoring of network and port status. They also include a management agent
that allows you to configure or monitor the switch using its embedded
management software, or via SNMP applications. To manage each switch, you
can make a direct connection to the console port (out-of-band), or you can
manage the switches through a network connection (in-band) using Telnet, the
on-board web agent, or SNMP-based network management software.
For a detailed description of the management features, refer to the Management
Guide.
