Figure 2.2.2: two@100Mb copper ports (528 model), 1@100Mb copper and 1@100Mb fiber ports (528F models), and 8@10Mb ports

All Magnum 500-Series Switching Hubs provide eight 10Mb switched ports. All 10Mb switched ports are independently auto-negotiating for selecting to operate in full-duplex mode, and will independently default to half-duplex mode when the 10Mb device at the other end is half-duplex or is not an auto-negotiating device.

The two Fast Ethernet switched ports on the Magnum 528 and 528F normally are set (by factory default) to operate at fixed 100Mb speed for guaranteed high-speed performance. In this case, each of these two ports will run at 100Mbps at all times. The user may select full- or half-duplex mode per-port with a manual switch for flexibility to adapt to any type of Fast Ethernet devices. The Full / Half-duplex manual switches are located on the front panel next to their corresponding Fast Ethernet ports.

For operation in Fast Ethernet auto-negotiating mode (copper only), internal jumpers must be set. The “AUTO” LED will then be lit to show that auto-negotiation is in operation. See Sections 4.4 and 3.4 for additional details.

On Magnum 528 units, there are three LED’s for each Fast Ethernet port. One indicates operation at 100Mb speed when lit, one indicates operation at 10Mb speed when lit (possible when auto-negotiation is enabled only, copper ports), and one is lit to indicate full-duplex operation (when it is OFF, operation is half-duplex). A twisted pair or 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 these LEDs to provide valid indications of operating conditions.
