23.Re-insert the controllers and reconnect the fibre channel cables.

24.Re-insert the power supply and fan units and reconnect the power supply cords.

25.(For DS4700 Express Storage Subsystems with dc power supply and fan units only) Turn on all attached disconnect devices before proceeding to step 26.

26.Power on the attached storage expansion enclosures.

27.Wait at least 3 minutes and then power on the DS4700 Express Storage Subsystem. Verify the status of the configuration using LEDs and the DS4000 Storage Manager client program.

28.After removing the faulty cage frame with midplane assembly, transpose the DS4700 Express serial number, machine type, and model tag from the faulty cage frame assembly to the Repair Identification (RID) tag on the new cage frame assembly. The RID tag is important in transferring the serial number, machine type, and model from the faulty cage frame assembly to the new cage frame assembly. Ensure that the new RID tag is affixed to the new cage frame assembly before you dispose of the faulty cage frame with midplane assembly. This will ensure that the warranty coverage is not interrupted.
