Installing the SFP transceiver 
The section describes how to insert an  SFP transceiver into an SFP slot. 
The SFP transceivers are hot pluggable  and hot swappable. You can plug-in and out 
the transceiver to/from any SFP port withou t having to power down the Industrial 
Switch. Shown in Figure 2-19.

•  Remove the transceiver module 
1. Make sure there is no network activity  by consulting or checking with the network 
administrator or through the management  interface of the switch/converter (if 
available) to disable the port in advance. 
2. Remove the Fiber Optic Cable gently.

X-Ring Application 
The industrial Switch supports the Rapid Ri ng (X-Ring) protocol that can help the 
network system to recovery from network co nnection failure within 20ms or less, and 
make the network system more reliable. The  X-Ring algorithm is similar to spanning 
tree protocol (STP) algorithm but its recovery  time is faster than STP. The following 
figure is a sample X-Ring application....

Coupling Ring Application 
In the network, it may have more than one X-Ring group. By using the coupling ring 
function, it can connect each X-Ring fo r the redundant backup. It can ensure the 
transmissions between two ring groups not to  fail. The following figure is a sample of 
coupling ring application.
