Dip Switch SW6 (Link Integrity)
The eight switches on dip switch SW6 allow you to enable or disable Link
Integrity for each port. The switches are labeled 1 through 8 and
correspond to the eight ports. The On position enables Link Integrity for
each port (default) and the Off position disables Link Integrity for each
port. The switch settings are initially configured in the On position,
therefore, all eight ports have Link Integrity enabled, as per the 10BASE-T
standard.

In general, you should enable Link Integrity. To conform to the 10BASE-T
standard, for example, a connection requires Link Integrity to be enabled.
You must disable Link Integrity to connect to older equipment which does
not conform to the 10BASE-T standard. Link Integrity must either be
enabled at both ends of the link or disabled at both ends or the module will
report a Link Integrity error.
