5–2 Installing/Removing the Power Supply
Publication 6181-UM001D-EN-P
The power supply for the RAC6181 Industrial Computer accepts an
input power and provides regulated lower voltages required for all
internal components such as the processor board, card connectors, and
chassis fan.
The RAC6181 Computer has the following power supply options:
•
AC power version with a 120/240V AC power supply.
•
DC power version with an 18-32 V DC power supply.
ATTENTION: Review safety precautions before
proceeding. Failure to follow proper safety procedures
could result in severe electrical shock or damage to the
RAC6181 Computer.
To remove the power supply (AC and DC option):
1. Disconnect power from the RAC6181 Computer.
2. Remove the back cover and the top cover.
Refer to procedures in Chapter 4 for details on removing the back
cover and top cover.
Important : You must take note of the location of all connectors before
you remove the existing power supply and cabling, so that
you can attach the wires from the new power supply.
Do not disconnect the wiring from the power supply itself
unless specified. The replacement power supply comes
with cabling attached.
3. Follow the wires as they exit the top (output side) of the power
supply and disconnect the wiring at the connectors of the other
components (i.e., CPU card, backplane, drives, etc.).
Pull on the connector to remove it: do not pull on the wires. Some
connectors have a mechanical latch that must be disengaged before
disconnecting. Make sure you adequately note the location of each
connector.
Note: In order to access the large 14-pin connector (P2) on
the 2-slot backplane, you must remove the top cover
and partially remove the CPU card and I/O card. Refer
to procedures in Chapter 4 for details on removing
cards.
