“Reverse” rack-mount models, there is a duplicate set of LEDs on the other (front) side
for normal status viewing from that direction. Of course, with management, the port
status data is also available in software.

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
6K25’s normally are set (factory
default) to operate in full-duplex mode for best fiber distance and performance. Using the
6K25’s MNS software, the user may select full- or half-duplex mode per-port through
set-up of the software (See Magnum 6K25 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.
