Perle Systems CM-10GT-XFPH, C-10GT-XFPH Test Function Switch 2 Test Mode, Switch Position Type

Test Function (Switch 2 – Test Mode)

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

Built In Link Test: Set Switch 2 to the Up position for the C/CM- 10GT media converter module to initiate the Built In Link Test on port 1. These tests consist of the media converter module generating test patterns to be sent out on port 1 to the remote media converter module. If the remote media converter module is also a compatible 10GBaseT media converter module then the remote media converter module will automatically be put into test mode.

Note: The BILT can operate on 10G modules. This feature can also be used with Perle S-10G media converters

Loopback: If Switch 2 is down, the specified port will be forced into loopback mode (switch 3 determines the port number). Data received on the receiver (RX) will be looped back to the transmitter (TX) connection. This mode is not used in conjunction with BILT. It can be used when other data generation methods are used.
