Caution – Do not disconnect the power cords from the system power inlets unless
you are installing or replacing the system control switch, the power distribution
board, the centerplane, the PCI riser board, or the system controller (SC) card. The
power cords ground the system.
4. Make sure that the power supply mounting screws are fully tightened.
5. Remove the four captive screws that secure the system to the left and right vertical
rails at the front of the rack.
Use a Phillips No. 2 screwdriver to remove the screws, which are in recessed access
holes in the decorative panels affixed to the system's front panel.
Note – The screws also secure the decorative panels to the chassis.
6. Slide the system chassis evenly out of the cabinet until the inner glides stop in the
slide.
Pull the system smoothly out of the enclosure, holding the system by the power
supply handles. Continue pulling the system until the back of the chassis clears the
enclosure and you hear the flat spring catches in the glides engage with an audible
clicking sound. The system is then fully extended and secure.
Note – If you need to remove the server completely from the cabinet, see
