Chapter 10: Frame and Control
Verification
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 the chassis breakers are in the OFF position.
3)
Verify all cards/modules are latched and secure.
4)
Verify all blank covers are in place and secure (no open slots in the frame).
5)
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).
6)
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).
7)
Proceed to System Startup.

TARTUP
Perform the Cheetah system startup sequence as follows:
1)
Energize the main power source to the chassis.
2)
Place both chassis breakers in the ON position (handles should be in the UP position). Secure the
breaker cover panel.
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 breaker-cover panel is securely in place. This panel is an integral
part of the chassis cooling system. A loose, broken, and/or missing breaker-
cover panel could result in destructive overheating of equipment
components.
