3. The sliding nut head must always face away from the enclosure, whichever configuration is used.
CAUTION: Use only the power cords supplied or cords that match the specification in Appendix B,
"AC power cords."
CAUTION: After the enclosure is installed in the rack, dispose of the lifting straps. Due to the
difficulty in attaching the straps once the enclosure is installed in the rack, the straps are not
suitable for removing the enclosure from the rack.
Inserting modules
See the Chapter 6, "Module replacement," on page 37 chapter for the following instructions:
• "Inserting a cooling module"
• "Inserting a PSU"
• "Inserting an SBB I/O module"
• "Inserting a DDIC"

Power cord connection

Observe all warnings related to power cords.
Important: When more than one PSU is fitted, connect each PSU to separate and independent supplies to
guarantee redundancy.
CAUTION: Always remove the power connections before you remove the PSU from the enclosure.
