SECTION 3
TESTING AND LANVIEW
3.1 INTRODUCTION.
This section lists procedures to test the MR-2000C Multiport Repeater after it
has been connected to the network. A description of LANVIEW and its function in troubleshooting phys-
ical layer network problems is also given.
3.2 INSTALLATION CHECK-OUT.
This section contains procedures to test the MR-2000C Multiport
Repeater after it has been installed to ensure that the physical layer of the network is operating properly.
Two Ethernet node testers that will generate valid data packets, such as Cabletron Systems’ LAN-MD, are
required for this procedure.
NOTE
This procedure should be performed only after testing each segment
with a TDR, such as Cabletron Systems’ TDR 5000, to verify that
the cable lengths, impedance and terminations are within IEEE
802.3 specification limits.
NOTE
For the purposes of this procedure, it is assumed that two
Cabletron Systems LAN-MDs are being used. For details on the
LAN-MD, refer to the LAN-MD User’s Manual.
1. Using a transceiver and an AUI cable, connect a LAN-MD to either of the segments connected to the
repeater.
2. Select and run test
6 - SERVER
.
If this test passes, leave the LAN-MD running.
This LAN-MD now acts as a
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 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 from and
sent back to the LAN-MD acting as the
SERVER
.
5. Select and run test
3 - ON NET XCVR
on both LAN-MDs.
Check that this test passes.
6. Remove a terminator from one of the segments connected to the MR-2000C.
The
FAULT
LED for that segment should light on the MR-2000C.
