B.1 Introduction
Figure B-1. CRS-280L Rear Panel (shown with PL/10207-1 AC Modules)
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.
