10BASE-T Module is initially configured to channel 1. To reconfigure the module to a different channel, refer to the information in Table 1-4.

If you have an ONline Ethernet Network Management Module installed in your concentrator, you can remotely override these switch settings.

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.
