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), and
full/half (F/H) duplex indicators.
The DC power plug connector or “jack” is in the left rear of the chassis. The external
power supply is 5VDC at either 95 - 125vac at 60 Hz for “-d” models or 120-230vac at 50Hz for
“-i” models that have IEC power cable connector in the external power supply housing.
2.2.2 Magnum P80C chassis with all RJ-45 Copper ports
The Magnum P80C chassis houses one main PC board. The power supply unit is
external. The front side of the chassis has eight twisted-pair switched ports. Port 2SW has
manually-selectable Full-Fixed and Auto-negotiation capability. See section 4.4.

The DC power plug connector or “jack” is in the left rear of the chassis, like the
P80F. The external 5VDC power supply is for either 95 - 125vac at 60 Hz for “-d” models or
120-230vac at 50Hz for “-i” models that have IEC power cable connector in the external power
supply housing
2.3 Up-link Port 1SW for Cascading
The unit has an up-link Port # 1 or 1SW, located on the left-front side of the Switch. It
enables the port’s twisted pair cable to cascade to another shared hub or switching hub port.
(See Section 4.6 for more details about up-link). Port #1SW is capable of full- and half-duplex
mode auto-sensing, based on the capability of the connected device. The up-link feature
operates the same, whether Port # 1SW is connected to either 100Mbps or 10Mbps devices.
