When the up-link port is used to cascade two P80-series Personal Switches, the auto-sensing
feature will cause the connecting link to operate at 100Mbps speed and full-duplex mode.
2.4 Fiber port, ST or SC Connector for Model P80F
100Mbps Fiber port, ST-type mm
or SC type (single-mode or multi-mode)
The Fast Ethernet fiber switched port on the Magnum P80F is set to operate at fixed
100Mb speed for guaranteed high performance. The P80F’s fiber port is factory-built as either a
multi-mode ST, multi-mode SC, multi-mode MTRJ or single-mode or long-reach SC connector.
The 100Mb fiber port will run at 100Mbs speed at all times with manually selected full- and
half-duplex capability. The 100Mbps fiber port is a switched port and performs as a domain,
providing a high bandwidth backbone connection (no media converter is required!) and
supporting long (up to 40km) fiber cable distances for installation versatility.
Ports 2SW (the fiber port) has an “F - H” user-selectable manual switch. When set in
the “F” position, it forces full-duplex mode. When set in the “H” position, it forces half-duplex
mode, still at 100Mbps speed.
On Magnum P80F units, there are three LED’s for the switched ports. One (LK/ACT)
is steady ON to indicate LINK, blinking indicates the port is transmitting and receiving. The
SPEED LED is ON for 100Mbps and OFF for 10 Mbps (when LINK is made). The F/H
indicates full-duplex when ON, when it is OFF, operation is half-duplex.
A fiber cable must be connected to the 100Mb port and a proper link (LK lit) must be
made with the device at the other end of the cable in order for these LEDs to provide valid
indications of operating conditions.
