Physical Inspection and Power On
The purpose of this step is to detect any obvious mechanical damage done to the chassis or to the system boards:
Check the chassis and the system boards for any sign of mechanical damage.
Check that all field-replaceable units—Switching and Forwarding Modules (SFMs), Flexible PIC Concentrators (FPCs), REs, MCSs, Compact Forwarding Engine Boards (CFEBs), power supplies, etc.—are correctly seated.
Connect the power supplies and turn them on one at a time.
