CHAPTER 4
TESTING AND LANVIEW
This section contains procedures to test the IRM after it has been
connected to the network. Descriptions of the LANVIEW LEDs on the
IRM are also provided.
4.1
INSTALLATION CHECK-OUT
After the IRM is connected to the network, verify that packets can be
passed between the two Ethernet network segments via the IRM. Two
Ethernet node testers capable of generating valid data packets, such as
Cabletron Systems' LAN-MDs™, are required for this procedure.
Before you begin, test each Ethernet segment connected to the IRM to
ensure that the segments meet IEEE 802.3 specification limits.
1. Using a transceiver and an AUI cable, connect a LAN-MD to the
applicable segment connected to the IRM.
2. Select and run test 6 - SERVER on the LAN-MD connected in step 1.
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, the LAN-MD is now
the SERVER unit and will act as a packet echoer when used with
another LAN-MD.
4. Using a transceiver and an AUI cable, connect another LAN-MD to
any other segment connected to the MMAC.
5. Select and run test 4 - NODE on the LAN-MD connected in the
previous step.
6. Verify that this test passes. At least 100 packets should be sent and
received with no errors. Packets will be sent from this LAN-MD to the
other LAN-MD, acting as the Server, then echoed back.
