Integration Guide Page 1 Revision: 0.00
Warning: The Enabler III LPP platform is designed with features
to support a robust connection. There are instances where the
module performance is beyond the control of the intended
design. Integrated designs that require 24 by 7 operation must
implement power control via an external circuit or by
implementing power management as specified within this design
guide.
