Test Function (Switch 2 – Test Mode)

Switch Position	Type
Up (default)	Built In Link Test
Down	Loopback

Built In Link Test: Switch 2 causes the S-10G to initiate the Built In Link Tests on the specified port. Switch 3 determines the specified port for the Built In Link Tests. If Switch 3 is Up, the tests will be run on Port 1. If the Switch is Down the tests will be run on Port 2. The other port will be disabled during these tests.

These tests consist of the media converter module generating test patterns to be sent out the selected port to the remote media converter. If the remote media converter is an S-10G, it will automatically be put into loopback mode.

Loopback: If Switch 2 is down, the specified port will be put into loopback mode. In this mode the port will be ready to receive the test patterns generated by the S-10G running the Built in Link Test. Switch 3 determines which port will be put into loopback mode. The other port will be disabled during the tests. If the remote device is also an S-10G media converter, this unit does not need to be put into test mode and there is no need to set the loopback switch. This will be taken care of by the Auto Loopback feature.
