CHAPTER 4
TESTING AND TROUBLESHOOTING
This chapter lists procedures to test the FR-3000 Fiber Optic Repeater after it has been con-
nected 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 FR-3000 Fiber Optic Repeater after it has been
installed to ensure that the physical layer of the network is operating properly. Two Ether-
net node testers capable of generating valid data packets, such as a 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 specifications.
1.
Using a transceiver and an AUI cable, connect a LAN-MD to either of the segments
connected to the FR-3000.
2.
Select and run test
6 - SERVER
. This LAN-MD now acts as the
SERVER
unit and
will act as a packet echoer when used with another LAN-MD.
3.
Using a transceiver and an AUI cable, connect another LAN-MD to the other segment
connected to the other repeater.
4.
Select and run test
4 - NODE
on the LAN-MD connected in step 3.
Check that this test passes.
At least 100 packets should be sent and received with no errors. The packets will be
received and sent back from the
SERVER
LAN-MD that was left running on the other
segment.
5.
Select and run test
3 - ON NET XCVR
on both LAN-MDs. Check that this test pass-
es.
6.
Remove a teminator from the segment connected to one of the FR-3000s. The
FAULT LED for that segment should light on the FR-3000.
7.
Reconnect the terminator removed in step 6.
8.
Check that the FAULT LED for that segment goes off.
9.
Repeat steps 6 through 8 for the segment connected to the other FR-3000.
When the FR-3000 Fiber Optic Repeaters have successfully completed these tests, they are
ready for normal operation. If any failures were noted, please contact Cabletron Systems'
Technical Support.
