11 Using a flat head screwdriver, re-install the plastic terminal block cover that
was removed in step 3.
12 Ensure that the power cable is properly dressed to the right and retained in
the cable support bracket to the right of the chassis. This helps relieve the
cord weight from the connector and avoid the inadvertent disconnection of
the power supply cord.
13 At the DC input circuit, restore power to the DC circuit.
The power supply will turn on.
14 Verify the power supply LEDs. The following LED indications should be
present on the 3930:
• PSA - Status LED is solid green, Input LED is solid green
• PSB - Status LED is solid green, Input LED is solid green
• PWR - solid green
The power supply has now been replaced.
WARNING: When making connections to the terminal block, make sure that no stray
strands of the input wire come into contact with any other part of the terminal block
