4 Run the P4, P5, or P6 power supply cable and the IDE cable to the hard disk. The I/O card is
not installed in the main unit for this step:
a Route the power cable between the I/O card chassis standoffs in the area shown (see
Figure 139 ). Run the IDE cable in the same manner.
b Tie-wrap the power cable to the hard disk cable. Position the tie-wrap 1/2 inch from the
hard disk cable sheathing.
c Ensure the remainder of the power cable does not interfere with internal components.
Note: Install the power supply carefully. Ensure the power supply cables are not
entangled or crushed against any internal components.
