Fiber ST above, fiber SC at right
The Magnum DS80F chassis
houses one main PC board. The power supply unit is external. The front side of the chassis has
eight RJ-45 twisted-pair ports and one 100Mbps fiber port. Port #2SW always supports fiber
ports only and the RJ-45 connector is inoperative at all times. LEDs to indicate operating status
of all ports are mounted on the top. There are power (PWR) and ERROR (self-test at power up
failed) indicators for the unit. For each port, there are Link and Activity (LINK/ACT) LEDs
indicating traffic, and speed (ON for
100Mbps). Switched ports 1SW and 2SW
have full-half (F-H) duplex indicators.
The DC power plug connector or
“jack” is in the left rear of the chassis. Rear View Magnum DS80-Series
