The above provided information enables a managed station( a PC or Console
terminal) to connect directly to the switch using a straight through cable.(Note:
The Null-Modem (DB-9) cable is optional and can be order from the factory,
along with the unit
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.

OPERATION
This chapter describes the functions and operation of the Magnum 6K25e
Switch.
4.1
Switching Functionality
A Magnum 6K25e provides switched connectivity at Ethernet wire-speed
among all of its ports. The Magnum 6K25e 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 6K25e,
but local traffic on a port will not consume any of the bandwidth on any other port.
