Chapter 11

Clustering is a way to provide access to the serial ports of many IOLANs 
through a single IP address. 

The IP address that will be used to access all clustered serial ports will be that of the Master IOLAN 
in the cluster. All other IOLANs in the cluster will be referred to as Slave IOLANs. Users can also 
access slave serial ports using EasyPort Web; EasyPort Web is automatically launched when a user 
types in the IP address of the Master IOLAN in a web browser. If the user has Admin privileges, the 
WebManager will first be displayed with an option to proceed to EasyPort Web.
The 

 window displays the slave IOLAN entries and the number of ports on 

those slave IOLANs.

The following buttons are available:

No special configuration is required on the Slave IOLANs to enable this functionality.

Click this button to display a window to configure and add a new Slave 

IOLAN’s configuration to the clustering group.

 for more information.

Select a Slave IOLAN and click this button to delete it from the clustering 

group.

Select a Slave IOLAN and click this button to configure the individual Slave 
IOLAN’s serial ports.
