Switch Architecture
The SF-2420GX 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.
The switch includes 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.
The switch also includes two slots on the rear panel for slide-in single-port
10GBASE modules with XFP transceivers.
Network Management Options
The switch contains a comprehensive array of LEDs for “at-a-glance” monitoring of
network and port status. It also includes a management agent that allows you to
configure or monitor the switch using its embedded management software, or via
SNMP applications. To manage the switch, you can make a direct connection to the
console port (out-of-band), or you can manage the switch through a network
connection (in-band) using Telnet, the on-board web agent, or SNMP-based network
management software.

Management Guide.
