The EM316-2SFP factory default configuration is designed to operate in the most common 
applications. 

 

Network Management = Enabled 
LIN = Disabled 
Loopback = Disabled 

 

 
The default configuration optimizes the EM316-2SFP module in most applications. Network 
management configuration does not override hardware DIP switch settings. These settings can 
only be changed using the DIP switches (SW1) on the EM316-2SFP module, regardless of 
previous card installations and network management configuration. 

 
Refer to network management sections of this document, the Command Line Interface User Guide, 
or MegaVision documentation for additional information about EM316-2SFP management.

Figure 5   -- DIP switches and PCB revision examples 

 
The DIP switch components and labeling has changed between PCB revisions. Figure 5 above 
illustrates some DIP switch examples by PCB revision. Note that the ON position in these 
revisions, as labeled on the DIP switch component, represents DISABLE for the feature as 

described in Figure 4. Refer to the pictures above for proper DIP switch polarity on the PCB 
revisions cited.
