5.1.2Power-up Results

After completion of the power-up diagnostic sequence, all status LEDs on the ATX front panel should be on (lit), indicating that the modules have passed the power-up tests.

Refer to Table 5-1 for descriptions of the LEDs during normal operation.

Table 5-1 Meaning of LEDs

LED

Meaning

 

 

 

 

RX

Token Ring port is receiving data (LED flashes)

 

 

ST

Ring status of port, on if port is inserted into the ring

 

 

PROC

Token Ring processor is ready for operation (LED on)

 

 

TX

Token Ring port is transmitting data (LED flashes)

 

 

16

If LED is on, then port ring speed is set for 16 Mbps, if not on then

port ring speed is set for 4 Mbps

 

 

 

POWER

Token Ring module hardware is receiving power (LED on)

 

 

5.2 OPERATIONAL DIAGNOSTICS

5.2.1Loopback Tests

Built-in local and remote loopback tests can be used to test individual ports while the ATX is operational. When in local loopback, a port is disconnected from its network. The ATX generates loopback packets for the port, and the port loops the packets back without sending them onto its network.

During a remote loopback test, the port is in normal operation, sending and receiving packets to its network. The ATX generates loopback packets which are sent out of the port to a particular destination device on the port’s network. The destination device echoes the packet back onto the network, and the originating port receives the packet.
