Operating Instructions

The green Ethernet Receive LED indicator blinks whenever the LXT970 is transmitting data via the 10/100-Base-T port.

4•4•4 Ethernet LINK Indicator - LD4

The yellow Ethernet Twisted Pair Link Integrity LED indicator - LINK, lights to indicate good link integrity on the 10/100-Base-T port. LD4 is off when the link integrity fails.

4•4•5 Fast Ethernet CLSN Indicator - LD5

The red Ethernet Collision LED indicator CLSN, lights whenever a collision condition is detected on the 10/100-Base-T port, i.e., simultaneous receive and transmit. This led functions in this duty provided that bits 7:6) of LXT970’s register 19, are cleared.

4•4•6 ATM RX Indicator - LD6

The green ATM Receive LED indicator blinks whenever the PM5350 ATM-UNI is receiving cells via the ATM port.

4•4•7 ATM TX Indicator - LD7

The green ATM Receive LED indicator blinks whenever the PM5350 ATM-UNI is transmitting cells via the ATM port.

4•4•8 TEXP Indicator - LD8

The green Timer Expired LED indicates status of Timer 4 output and lights when it’s low.

4•4•9 Signaling Indicator 1 - LD9

This red indication LED has no dedicated function over the ADS. It is meant to provide additional visibility for program behavior. Its different color from LD9 provides additional information. It is con- trolled by BCSR0/7. When either of HRESET or Power-On-Reset is asserted the LED lights as well.

4•4•10 Signaling Indicator 0 - LD10

This green indication LED has no dedicated function over the ADS. It is meant to provide some visibility for program behavior. It is controlled by BCSR0/6. When either of SRESET or Power-On- Reset is asserted the LED lights as well.

4•4•11 RS232 Port 2 ON - LD11

When the yellow RS232 Port 2 ON LED is lit, it designates that the RS232 transceiver connected to P27B, is active and communication via that medium is allowed. When darkened, it designates, that the transceiver is in shutdown mode and its associated SMC1 pins may be used off-board via the expansion connectors.

4•4•12 RS232 Port 1 ON - LD12

When the yellow RS232 Port 1 ON LED is lit, it designates, that the RS232 transceiver connected to P27A, is active and communication via that medium is allowed. When darkened, it designates that the transceiver is in shutdown mode and its associated SCC1 pins may be used off-board via the expansion connectors.

4•4•13 Fast Ethernet Port Initially Enabled - LD13

When the yellow FETH ON LED is lit, it indicates that the fast ethernet port transceiver - the LXT970, is initially active. When it is dark, it indicates that the LXT970 is initially in power down mode, enabling the use of its associated FCC2 pins off-board via the expansion connectors. The state of LD13 is controlled by bit BCSR1/4.

This is a soft-indication, i.e., since the LXT970 may be controlled via the MII port, it is possible that the state of LD13 does not reflect correctly the status of the LXT970.
