TESTING AND LANVIEW

3.1INTRODUCTION

This section lists procedures to ensure that the segments connected to the Cabletron Systems THN-MIM are operating properly. A description of LANVIEW LEDs and their function in troubleshooting physical layer network problems are also provided.

3.2INSTALLATION CHECK-OUT

This section contains procedures to test that the physical layer of the network and a coaxial segment connected to the THN-MIM are operating properly. This section also contains procedures to check that the physical layer of the network is operating properly. An Ethernet node tester that will generate valid data packets, such as Cabletron Systems LAN-MD, is required for this procedure.

NOTE: This procedure should be performed only after testing each segment to verify that the cable lengths, impedance and terminations are within IEEE 802.3 specification limits.

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 the segment connected to the applicable BNC port.

2.Select and run test 6 - SERVER.

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 any other tested segment connected to the MMAC.

4.Select and run test 4 - NODE on the LAN-MD connected in step 3.
