Replacing the enclosure

Complete this task to replace the server or the expansion enclosure.

1. Take the enclosure offline.
   1. Take all of the connected hosts offline.
   2. Press the power button on the rear operator panel of the server enclosure to power-off the server enclosure and all connected expansion enclosures.
2. Disconnect the faulty enclosure from all other machines.
   1. Disconnect the power cord from the power source and the power supply.
   2. Disconnect all connected hosts if you are removing a server enclosure. Mark the cables so that you can return them to the same locations on the new enclosure.
   3. Disconnect all connected enclosures. Mark the cables so that you can return them to the same locations on the new enclosure.
   4. Disconnect the management console if you are removing a server enclosure.
3. Remove all of the hardware resources, such as the battery backup units, processor cards, power supplies, rear operator panel, front display panel, right-side bezel, and DDMs, from the enclosure. Place the removed hardware resources where they will not be damaged.
   Important: You must replace all of the resources in the same location that you removed them from. Ensure that you mark the resources so that they are replaced correctly.
4. Remove the faulty enclosure from the rack.
5. Unpack the new enclosure. Place the packing materials aside where they will not be damaged. You must pack the failed enclosure in the same packing materials that came with the new enclosure.
6. Remove all of the hardware resources from the new enclosure and set them aside in a different location from the hardware resources that belong in the failed enclosure.
   Note: The hardware resources that you remove from the new enclosure must be returned within the faulty enclosure. Do not place any of the newly shipped hardware resources in your new enclosure.
7. Ensure that the model type and serial number label information from the faulty enclosure is affixed to the new enclosure. After removing the faulty enclosure, capture the serial number and model type information from the faulty enclosure and transpose it to the RID tag for the new enclosure. Ensure that the new RID tag is affixed to the new enclosure before you install the new enclosure in the rack.
8. Insert all of the hardware resources from the new enclosure into the failed enclosure.
9. Reuse the packing material from the new enclosure to pack the failed enclosure (with the new hardware resources) into the same box that was used to send the new enclosure.
10. Install the new enclosure in the rack.
11. Carefully insert all of the hardware resources that came from the previously failed enclosure, such as the battery backup units, processor cards, power supplies, rear operator panel, front display panel, right front bezel, and DDMs, into the new enclosure. Use the resource markings that you created when you removed the resources to ensure that you place each resource in the same location that you pulled it from. Also, you must ensure that each of the resources is securely latched into place.
12. Reconnect the new enclosure to the other machines, using the same configurations as the previous enclosure.
    1. Reconnect all applicable hosts if you are replacing a server enclosure. Refer to your previous cable marking to ensure that you connect the cables to the same locations that you removed them from.
    2. Reconnect all required enclosures. Refer to your previous cable marking to ensure that you connect the cables to the same locations that you removed them from.
    3. Reconnect the management console if you are replacing a server enclosure.
    4. Reconnect the power cord from the power source to the power supply.
13. Power on the server enclosure and all connected expansion enclosures by pressing the power button on the rear operator panel of the server enclosure.
