The above information enables a management station (a PC or Console terminal) to

connect directly to the Switch Console using a straight-through serial cable

NOTE for Power Substations: In support of the IEEE 1613 Class 2 standard, GCI

advises that, for substation applications, the serial RJ-45console ports are

intended for temporary connectivity to other equipment such as PCs. Since the

console port connection is temporary, it is excluded from IEEE 1613 packet-

loss testing per the 1613 standard-defined test procedure.

4.0 OPERATION

This chapter describes the functions and operation of the Magnum 6K8-Series

Switch.

4.1 Switching Functionality

A Magnum 6K8-Series provides switched connectivity at Ethernet wire-speed

among all of its ports. The Magnum 6K8-Series supports10/100Mbs for copper media

and 10 or 100Mb separate traffic domains for fiber ports to maximize bandwidth

utilization and network performance. All ports can communicate to all other ports in a

Magnum 6K8-Series, but local traffic on a port will not consume any of the bandwidth

on any other port.
