Inserting Batteries in the Processor Module 2
The processor module uses two AAA-size standard alkaline batteries to guard against the loss of
system programming and time of day clock settings in case of a power failure for 45 days to six
months, depending on the freshness of the batteries. You should replace the batteries every year.
CAUTION:
Batteries and battery cover are packaged in a separate box. If you are replacing batteries,
the old batteries must be removed with the power on or the system programming will be lost.
You should back up the system programming before changing the batteries. See “Battery
Replacement” on page 10-1.
You ground the system by running a solid copper wire from the processor module to an
appropriate earth ground. Follow these steps to ground the system:
1. Attach one end of a #12 AWG or #14 AWG solid
copper wire to the grounding screw on the
processor module (see Figure 2-12). The length
of the wire must not exceed 35 feet (7.6 meters).
2. Route the wire through the wire manager on the
front of the module.
3. Attach the other end of the wire to the approved
earth ground, such as building steel or a cold
water pipe.

The configuration of the 1600 DSL module is not backed up to the PCMCIA card. Instead,
the configuration is retained in the flash memory of the 1600 DSL module.
