TESTING AND TROUBLESHOOTING

4-4

b. EPIM-F1 or EPIM-F2 installed in the MRXI:

1.) Connect a properly functioning Cabletron Systems FOT-F 

Fiber Optic Transceiver to the device end of the Fiber Optic 

Link Segment coming from the EPIM-F1/F2.

2.) Connect a LAN-MD to the FOT-F by using an AUI cable.

c.

EPIM-C installed in the MRXI:

1.) Connect a transceiver and an AUI cable to the Thin-net 

segment.

2.) Connect a LAN-MD to the AUI cable.

d. EPIM-A installed in the MRXI:

1.) Attach an external transceiver to the segment coming from the 

port on the EPIM-A.

2.) Connect a LAN-MD to the transceiver by using an AUI cable.

2. Select and run test 6 - SERVER on either LAN-MD connected to the 

Ethernet network on either side of the wide area link.

3. Verify that the Test Status PASS LED is lit and that the Status Code 

reads 000 or 001. If these two conditions exist, the LAN-MD is now 

the SERVER unit and, when used with another LAN-MD, will echo 

packets.

4. Select and run test 4 - NODE CHECK on the LAN-MD connected to 

the Ethernet network on the other side of the wide area link.

5. Verify that this test passes by ensuring at least 100 packets are sent and 

received between LAN-MDs with no errors. Packets are sent from this 

LAN-MD to the LAN-MD at the other end of the wide area link, acting 

as the Server, then echoed back.

After successfully completing these tests using the links, the MRXI is 

ready for normal operation. If you note any failures, contact Cabletron 

Systems Technical Support.
