Page 2 - 8INSTALLING THE ADAPTERS2.5.1 Using LANVIEW LEDsThe FDDI network adapters employ four LANVIEW LEDs. Thefunctions of these LEDs are explained below:Processor LED (red)The F30XX and F70XX model FDDI adapters use an on-boardMotorola 68ec020 CPU. The Processor LED flashes at differentrates to indicate on-board processor conditions.• When the Processor LED flashes at a rate of one flash persecond (the “heartbeat”) it indicates that the processor isfunctioning normally. Note that the heartbeat is notcontinuous - the heartbeat will only be displayed for a periodof thirty seconds after power up.• When the Processor LED is on continuously (not flashing), itindicates adapter failure. Reload the network driver to causethe SMT code to be updated. If the continuous indicationpersists, contact Cabletron Technical Support.Receive Data (yellow)The Receive Data LED illuminates to indicate that packets arebeing received from the FDDI network.Transmit Data (green)The Transmit Data LED illuminates when packets are beingtransmitted by the FDDI adapter onto the FDDI network.Bicolor LEDThis LED indicates one of three possible FDDI link conditions.• Illuminates in red to indicate No Connection to the FDDInetwork. Check all connections to the FDDI link.• Remains unlit to indicate Signal Detect (a signal is beingreceived from the FDDI network, but the adapter is unable toestablish a link with another FDDI device).
