Removing a power-supply paddle card from an expansion enclosure
Note: The following information describes how to remove a power-supply paddle
card from an I/O enclosure. Removing the power-supply paddle card from
another type of expansion enclosure is similar. A power-supply paddle card is
rarely used in an expansion enclosure.
To remove a power-supply paddle card from an expansion enclosure, complete the
following steps.
1. Read the safety information that begins on page vii and “Installation guidelines”
on page 71.
2. If the system-board tray is installed in a chassis, remove it (see “Removing the
system-board tray from a 2U chassis” on page 75).
3. Carefully set the system-board tray on a flat, static-protective surface.
4. Remove the expansion enclosure and set it on a flat, static-protective surface
(see “Removing an expansion enclosure from a system-board tray” on page 73).
5. If any 3.5-inch simple-swap drives are installed in the expansion enclosure,
complete the following steps:
a. Remove the 3.5-inch drives (see “Removing a 3.5-inch simple-swap hard
disk drive” on page 90).
b. Note the cable routing of the hard disk drive bracket and cable assembly
cables; then, disconnect the cables.
c. Remove the hard disk drive bracket and cable assembly (see “Removing
and installing a one-bay or four-bay hard disk drive bracket and cable
assembly” on page 108).
6. Make a note of where cables are attached to the power-supply paddle card;
then, disconnect them.
7. Remove the four screws that secure the power-supply paddle card to the
expansion enclosure and save them for future use.
8. Lift the power-supply paddle card out of the expansion enclosure.
9. If you are instructed to return the power-supply paddle card, follow all packaging
instructions, and use any packaging materials for shipping that are supplied to
