Chapter 4:
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 main power source is OFF (de-energized).
2)
Verify 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 power cables are properly connected to primary power distribution system.
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 system startup sequence as follows:
1)
Energize main power source to chassis.
2)
Place both chassis breakers in the ON position (handles should be in the UP position).
There is a 30 to 45 second delay prior to the system energizing frame components.
Following this delay period the system will energize and the circuit cards and modules
will perform initial self-diagnostics.
3)
Verify the following LED conditions:
Should any status LED indicate an error on the card or module, perform
troubleshooting sequences to correct the problem(s) prior to placing the
system in service.
a.
Observe each Power Supply module and verify the
