3.2.1
Setting the SQE Switch
The Signal Quality Error (SQE) Test Switch allows you to enable
or disable the SQE (“heartbeat”) test function. The SQE switch
is the two position switch on the right side of the FOT-F3, located
above the fiber optic ports (see Figure 3-1). The SQE test
function is disabled when the transceiver is shipped.
Note:
The SQE test function must be
disabled
if you are
connecting the transceiver to Ethernet Version 1 equipment or
to a repeater.
Set the SQE Switch as follows:
•
To disable the SQE test function, set the switch (Figure 3-1)
towards the optical ports to the off ( ) setting.
•
To enable the SQE test function, set the switch (Figure 3-1)
away from the optical ports to the on ( ) setting on the label.
