Introduction
The CRS-280L L-Band IF Switch for 1:N Redundancy features dual power supply modules: the standard AC module (CEFD P/N Pl/10207-1), or
the optional DC module (CEFD P/N PL 0000355). These modules are the only field replaceable components in the CRS-280L.
This appendix illustrates the procedure required to remove and install a CRS-280L power supply module (Figure B 1) into any CRS 280L L-Band
IF Switch unit.
Unless otherwise noted, while the illustrations throughout this appendix visually depict the replacement of a standard PL/10207-1 AC Power
Supply Module, this procedure is typical for removing and installing either a standard AC or optional DC power supply module into the applicable
A or B compartment in the rear of the CRS 280L chassis.
