	their speed is internally fixed at 100Mb (no auto-negotiation, no
	10Mb speed).
10 LED	: One for each “100Mb” port, ON when the copper port speed is
	10Mb/s.
100 LED	: One for each “100Mb” port, ON when the port speed is 100Mb/s.

Figure 4.3 : Up-link and F/H manual switches on front panel

The unit has a manual Up-link switch, located on the front panel next to 10Mb Port # 8 which it controls. It enables the port’s cable to either connect to a user station node (= position) or to be cascaded (X position) to a another 10Mb repeater or switching hub in the network. Verify proper Up-link switch position by noting Port 8’s LK/RX LED status, which is illuminated when a proper link is made. (Note: for optional up-link setting on 100Mb copper port #1 via an internal switch, see Section 3.4)

The two F/H switches are located next to each Fast Ethernet port on Magnum 528’s. When the two Fast Ethernet ports of a Model 528 are set to operate at fixed 100Mb speed (no auto-negotiation), manual selection of half or full duplex at 100Mb
