3.3 DIP Switch Configuration
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.
