(ACT) on the port. A fiber cable must be connected to each 100Mb port and a proper link
LK lit) must be made with the device at the other end of the cable in order for the LK
LEDs to provide valid indications of operating conditions.
The 10Mb model FPM10-MST fiber port module is the
same as the 100Mb FPM-MST, except for 10 Mb speed rather
than 100Mb speed. It supports distances according to the
10Base-FL standard, i.e., 2Km distance for multi-mode fiber.
(Single-mode for 10km distance may be available as a special
order).
2.2.5 10/100 Dual-speed Switched ports, RJ-45 (copper) The Magnum 4K8 copper has 8 port dual speed 10/100Mb switched. RJ-45
ports. The 10/100Mb switched ports are independently N-way auto-negotiating (as a
default setting),
for operation at 10 or 100Mb
speed in full- or half-duplex mode. They independently move to half-duplex mode at 10
Mb or at 100Mb speed if the device at the other end of the twisted pair cable is half-
duplex or is not an auto-negotiating device.
There are three LED’s for each port. The LK/Act (Link/Activity) steady ON
for Link with no traffic and blinking indicates port is receiving and transmitting. The
Speed LED indicates operation at 100Mb speed when ON and at 10 Mb speed when OFF
(when auto-negotiation is not disabled). The F/H LED is ON to indicate full-duplex
operation and OFF to indicate half-duplex mode. A twisted pair cable must be connected
into each RJ-45 10/100Mb port and a proper Link (LK lit) must be made with the device
at the other end of the cable in order for the LEDs to provide valid indications of
operating conditions.
The port#1 is equipped with a Media Dependent Interface-Crossover (MDI-
X) push-button switch to simplify cascaded or up-link connections.
