Pause (Switches 3 & 4)
The pause feature can improve network performance by allowing one end of
the link to signal the other to discontinue frame transmission for a set period
of time to relieve buffer congestion.
To properly set the pause feature in the network, the link partner (i.e., the
device to which the SFMFF13xx-28x is linked) must also have comparable
pause switches.
If the link partner does not have the pause feature, disable
the pause feature on the SFMFF13xx-28x media converter.
The SFMFF13xx-28x has four pause
options (listed below). To the right of each
option, a drawing shows the switch
settings for the SFMFF13xx-28x and the
link partner.
