14.Grasp the blue handle in the center of the front cage frame and pull it outward to slide the front cage frame out approximately two inches. Grab the two sides of the front cage frame and remove it from the chassis.

Note: The front cage frame might be tightly secured in the chassis. IBM recommends mounting the DS4700 Express chassis back in the rack using the four M5 screws to hold the DS4700 Express chassis in place while you pull on the blue handle to separate the front cage frame from the chassis. Remove the DS4700 Express chassis from the rack and place it on a level surface after you remove the failed front cage frame for the next step.

15.Unpack the new front cage frame with the midplane. Save the packaging materials in case you need to return it.

16.Insert the new front cage plane/midplane by aligning it with the storage subsystem front opening and slowly sliding it into the storage subsystem chassis. Make sure that the front cage frame EMC gaskets do not snag between the frame and chassis.

17.Tighten the four front cage frame screws. See Figure 118 on page 180.

18.Install the seven Phillips screws (three on top and four on bottom) that hold the front cage frame to the EXP810 chassis that you removed in step 13 on page 180, as shown in Figure 119.

19.Push the chassis all the way back into the rail and install the four M5 screws along the side edges of the DS4700 Express chassis.

20.Install the four Phillips screws on the back along the sides of the DS4700 Express chassis that hold the DS4700 Express to the rails.

21.Insert the E-DDM CRUs. Be sure you insert them in the correct slots. Use the labels you put on them before you removed them to guide you.

22.Replace the Telco bezel, if applicable. See “Removing and replacing a bezel” on page 150 for instructions.
