Understanding Digital Module Kit redundancy

You can install one or two Digital Module Kits. Only a single (primary) Digital Module Kit is required for

non-redundant operation. This non-redundant configuration provides less protection from potential faults in

Digital Module Kit components. See Figure 10

For non-redundant systems, use the following installation guidelines:

• The primary Digital Module Kit modules install in slots 2, 3, and 4.

• The primary GPS antenna cable connects to a GPS antenna.

For redundancy, install two Digital Module Kits.

• The secondary Digital Module Kit modules install in slots 6, 7 and 8

• The secondary GPS antenna cable connects to a second GPS antenna.

NOTE

There is no hardware or software requirement that the primary

Digital Module Kit is installed in slots 2, 3, and 4 and secondary

in 6, 7, and 8. The primary can be installed in slots 6, 7, and 8,

and the secondary in slots 2, 3, and 4. However, this guideline is

followed throughout this guide for clarity.
