Introduction
Prior to splitting the existing QPSK modulators, you must prepare the new QPSK
modulators and demodulators for the split. This section provides a procedure for
preparing the new QPSK modulators and demodulators.

preparing the new QPSK modulators and demodulators.
Important: Do not connect the new QPSK modulators and demodulators to the RF
network at this time.

This preparation process involves the following tasks:
Reboot the cable boxes on each QPSK modulator involved in the split.
Configure and update the IP addresses for the new QPSK modulators and
demodulators and the cable boxes you are planning to split from the existing
QPSK modulators and demodulators to the new QPSK modulators and
demodulators.
