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 or Telnet application, or via a direct connection to
the console port. The switch includes a built-in network management agent that
allows it to be managed in-band using SNMP or RMON (Groups 1, 2, 3, 9)
protocols. It also has an RJ-45 serial port on the front panel for out-of-band
management. A PC may be connected to this port for configuration and
monitoring out-of-band through a straight-through UTP or STP Ethernet cable
and the included RJ-45-to-DB-9 converter.

Guide .

ORTS
The switch provides 24 SC ports on the front of the switch. Each single-fiber SC
connector supports a 100BASE-FX full-duplex link to a subscriber’s CPE. The
switch’s fiber transceivers use Wavelength Division Multiplexing (WDM)
technology to achieve bi-directional operation (1550 nm transmit, 1310 nm
receive) over a single optical fiber. The WDM single-mode fiber links can run up
to 15 km.
The 100 Mbps bandwidth of the fiber links can be restricted by rate-limiting,
which is configurable thorugh switch management. Each port also supports
