Verifying LAN-to-LAN Operation
Once you have completed the installation, verify that the MA-427 LAN Bridge is operating properly
by checking LAN-to-LAN operation with your network administrator. You can also verify the
operation of the MA-427 by checking its LEDs. Table 18 describes the LEDs and their state under
normal operating conditions when connected to a functioning LAN.
