..
In an eight-port SFF fiber port module, all of the fiber ports are of the same
speed (100Mb), mode, and connector type. Models are available with Small Form Factor
(SFF) are multi-mode MT-RJ or LC-
type connectors, and single-mode
LC-type connectors.
The 100Mb fiber eight-
port modules for the Magnum
6K25e’s normally are set (factory
default) to operate in full-duplex mode for best fiber distance and performance. Using the
6K25e’s MNS software, the user may select full- or half-duplex mode per-port through
set-up of the software (See Magnum 6K25e MNS Software Manual) for the flexibility to
adapt to any FDX or HDX type of Fast Ethernet devices).
There are three LED’s per fiber port. The Link (LK) LED indicates “ready for
operation” on that port when lit, the F/H LED indicates operation in full-duplex mode
when ON (half-duplex when OFF), and the blinking ACT LED indicates receiving
Activity on the port. A fiber cable must be connected into a SFF port and the Link (LK)
indicator for that port must be ON (indicating there is a powered-up device at the other
end of the cable) in order for a LK LED to provide valid indications of operating
conditions on that port.

Eight-Port Copper Module, 6K8-RJ45
The 6K25e-Series’s 8-port
Copper port module, model
6K8-RJ45, provides eight
10/100Mb switched RJ-45
ports. The 10/100Mb switched
ports normally (as a default
setting) are independently N-
way auto-negotiating, and auto-
crossover(MDIX) for operation at 10 or 100Mb speed in full- or half-duplex mode, i.e.,
each independently selects a mode and speed to match the device at the other end of the
twisted pair cable.
(See Section 4.3 for auto-negotiation and MDIX details). The auto-crossover feature will
automatically determine the other side of connection to make the connection, and
