on page 95.

lever and pull the power supply out of the bay, using the handle.
b. Lift up the power-supply cage handle and pull the power-supply cage
assembly all the way up until the retainer latch locks the cage in place on
the chassis.
v
Non-hot-swap models, lift up the power-supply cage handle and pull the
power-supply cage assembly all the way up until the retainer latch locks the
cage in place on the chassis.
5. Disconnect any cables that impede access to the DIMMs.
6. Locate the DIMM connector that contains the DIMM that is to be replaced (see
“System-board option connectors” on page 13 for DIMM slot locations).

connectors, open and close the clips gently.
