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 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’s memory will be lost.
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.

In Release 4.0 and later systems, 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.
