PWR          :  Power LED, ON when AC power is applied to the unit. 
LK/RX       :  Link/Receive LED per 10Mb port, Steady ON for Link, Flashing

when the port has Receive activity.

FDX           : Full / Half Duplex LED per 10Mb port, ON when the port has

auto-negotiated to operate Full Duplex, OFF for half duplex.

AUTO        : Auto-negotiation LED, ON when  copper “100Mb” ports are

configured to operate in the auto-negotiation mode, OFF when
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.
F/H            : Full / Half duplex LED, one for each 100Mb port, ON when the

port is running full duplex, OFF for half duplex.   

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
