Converting from One Modular Configuration Power System to Another
This section describes how to convert from one modular configuration power system to another (either from
modular AC to modular DC, or from modular DC to modular AC).
Steps
To convert an LCC with a modular configuration power system from AC to DC power, or from DC to AC
power, perform the following steps:

DETAILED STEPS
Step 1
Power down the chassis completely and turn the facility power breakers to the OFF position.
Step 2
Remove the AC or DC PMs.
Step 3
Remove the alarm modules.
Step 4
Remove the power shelves.
Color
Function or Meaning
Green
On: The input voltage is present and within regulation range.
Blinking: The input voltage is present but out of regulation range.
Off: The input voltage is not present.
Green
On: The output voltage is on.
Blinking: The PM is in a power limit or an OC condition.
Off: The output voltage is off.
Red
On: An internal fault is detected within the PM.
Off: The PM has no internal fault.
Power down the chassis completely and turn the facility power breakers to the OFF position.
Remove the AC or DC PMs.
Remove the alarm modules.
Remove the power shelves.
Unplug the AC power cords or remove the DC fusing from the power source. Remove the AC or DC
wiring from the rear of the power shelf.
Install the new power shelves.
Install the power shelf wiring.
Install the alarm modules.
Install the AC or DC PMs.
Power the chassis back up.
