TESTING/TROUBLESHOOTING
This chapter includes information for testing your TPXMIM before and
after connecting it to your network, and troubleshooting network and
TPXMIM operational problems.
4.1 PRE-INSTALLATION TEST
Before installing the TPXMIM in a live network, test the module in a
controlled situation to ensure that it is repeating packets. This test requires
an MMAC containing an EMME (or equivalent multichannel
management module) and the TPXMIM. You perform the test with two
workstations (Figure 4-1).
1. Install the EMME and the TPXMIM into a stand-alone MMAC.
2. Connect the first workstation to either the TPXMIM, using the
appropriate cable and transceiver, or to the EMME through the active
AUI port (normally AUI 1).
Note: The EMME uses the AUI 1 port as the default active bridge port.
If you want to test modules using the AUI 2 port, you must select that
port using EMME Local Management.
3. Connect the second workstation to the TPXMIM, using the
appropriate transceivers and cable.
4. Set the first workstation as the file server and the second as the client
(refer to specific workstation documentation for setting file server and
client). After setting up the workstations, send packets between the
workstations and verify that the module operates properly.
If failures occur, contact Cabletron Technical Support.
Note: A "ping" test verifies that the TPXMIM is operating properly.
