Echo test
Install the test target boards shown in Table 4-1.
Under 100 Mbps or 10 Mbps LAN environment, connect machines containing the test target boards.
Figure 4.1 shows a connection sample.
Note:
• Start T&D on the Slave side first.
• Plural tests cannot be done with one HUB.
• This test cannot be done with HUB, which is in use.
• Initialize MAC address-to-port mapping information before execution when using
switching HUB (which supports the MAC address learning).
• In transmit rate auto-change mode, connect between the boards with 100BASE-TX reverse cable.
