This chapter lists procedures to test the LR-2000 Local Repeater after it has been
connected to the network. A description of LANVIEW and its function in troubleshooting
physical layer network problems is also given.
4.1 INSTALLATION CHECK-OUT
This section contains procedures to test the LR-2000 Local Repeater after it has been
installed to ensure that the the physical layer of the network is operating properly. Two
Ethernet node testers that will generate valid data packets, such as Cabletron Systems'
LAN-MDs , are required for this procedure.
Before you begin, test each segment connected to the repeater to ensure that the segment
meets IEEE 802.3 specification limits.
1.
Using a transceiver (1, Fig. 4-1) and an AUI cable, connect a LAN-MD (2) to either of
the segments connected to the LR-2000 (3).
2.
Select and run test 6 - SERVER.
3.
Verify that the Test Status PASS LED is lit and that the status code reads 000 or
001. If these two conditions are met, this LAN-MD now acts as a SERVER unit and
will act as a packet echoer when used with another LAN-MD.
4.
Using a transceiver (5) and an AUI cable, connect another LAN-MD (4) to the other
segment connected to the LR-2000.
5.
Select and run test 4 - NODE on the LAN-MD connected in step 4.
6.
Verify that this test passes. At least 100 packets should be sent and received with no
errors. The packets will be received from and sent back to the LAN-MD acting as
the SERVER.
When the LR-2000 Local Repeater has successfully completed these tests, it is ready
for normal operation. If any failures were noted, please contact Cabletron Systems'
Technical Support.
