Step 8 After ensuring that all wire connections are secure, reinstall the terminal block cover.
Caution To prevent a short circuit or shock hazard after wiring the DC-input power supply, reinstall the terminal
block cover.
Caution In a system with dual power supplies, connect each power supply to a separate input line. In case of a
line failure, the second source will most likely still be available.
Step 9 Remove the tape from the circuit breaker switch handle, and restore power by moving the circuit breaker
switch handle to the On (|) position.
Step 10 Verify power supply operation by checking that the power supply front panel LEDs are in the following
states:
• INPUT OK LED is green
• FAN OK LED is green
• OUTPUT FAIL LED is not lit
If the LEDs indicate a power problem, see the “Identifying Startup Problems” section on page 4-2.
