Components are enclosed in an air-cooled chassis that may be either mounted in a
standard rack or used as a stand-alone unit. The front panel has controls with an LCD
that you can use to view status or configuration, and an RJ-45 Ethernet connector
that allows you to manage the switch remotely.

The switching function is based on a central memory bank associated with its data
path control. Each switch port stores received frames in this memory, passing a buffer
pointer to the forwarding port's transmitter. The switch uses cut-through routing to
route frames from the receiving port to the transmitting port, providing the transmit
port is free, without waiting for the end of the frame to be received. This provides a
low-latency data path within the switch. The frame can be temporarily stored in the
memory bank but only if the transmit port is busy.
