ERIFICATION
This section addresses the system components, frame, and control verification sequences that should be
performed prior to energizing the system and placing the system in service. Attention to this section
will minimize system startup and in-service malfunctions.

HECKLIST
A system pre-start verification checklist includes a visual inspection to account for basic setup
functions that, if incorrect, could result in immediate system startup malfunctions. The following
basic checks should be performed prior to energizing any Cheetah chassis:
1. Verify the main power source is OFF (de-energized).
2. Verify all cards/modules are latched and secure.
3. Verify all blank covers are in place and secure (no open slots in the frame).
4. Verify the line cord(s) are connected to the chassis and are properly terminated to the source
power distribution system (i.e., connectors plugged in or pigtails terminated).
5. Inspect for unusual items such as loose wiring, frayed cabling, loose connections or
components, and missing cards/modules (basically, check for anything that seems out of
place or could present a problem).
6. Proceed to System Startup.

TARTUP
Perform the Cheetah system startup sequence as follows:
1. Energize the main power source to the chassis.
Result: The system has a 30 to 45 second delay prior to energizing the components. When
the delay has expired, the system will energize and the cards will perform initial
self-diagnostics.
Verify the blank-cover panels are securely in place. These panels are an
integral part of the chassis cooling system. A loose, broken, and/or missing
blank-cover panel could result in destructive overheating of equipment
components.
