Replacing an Enclosure

  1. Prepare the 7226 Storage Enclosure for Service. See Preparing the 7226 Storage Enclosure for Removal or Installation of a Storage Device or Other Component for the correct procedure.
  2. Remove the 7226 Storage Enclosure from the rack (see Removing the 7226 Storage Enclosure from a Rack) and place it on an ESD protected work surface.
  3. Remove the new Enclosure FRU from its packaging and install it in onto the slide rails. Pull the slide rails forward 1 until they click, twice, into place. Carefully lift the Enclosure FRU and tilt it into position over the slide rails so that the rear posts 2 on the Enclosure FRU line up with the rear slots 3 on the slide rails. Slide the server down until the rear posts slip into the two rear slots, and then slowly lower the front of the Enclosure FRU 4 until the other posts slip into the other slots on the slide rails. Make sure that the front latch 5 slides over the posts.

  4. Note the location of the devices in the old 7226. Remove the Half High Bay Blanks from those locations in the Enclosure FRU. To remove the Half High Bay Blank, push the drive latch 1 toward the Half High Bay Blank and begin to pull the blank out of the enclosure. Grasp the Bay Blank 2 and pull it out of the enclosure.

  5. Remove the Tape Drives, RDX Docking stations, and Slim Drive Tray Assemblies from the 7226. To remove the devices, push the drive latch 1 toward the drive assembly and begin to pull the drive out of the enclosure. Grasp the drive 2 and pull the assembly out of the drive bay. Disconnect the cables 3 from the drive assembly.
    Note: Do not remove the DVD-Ram Drives or the re-driver or converter cards from the Slim Drive Assemblies.

    For a 7226 Storage Enclosure that does not contain a Front USB port, go to step 14. For a 7226 Storage Enclosure installed in PureFlex systems with a Front USB port, continue to step 11.
  11. For the USB Interface (Front) Assembly (PureFlex systems only), remove the Front USB bezel by pressing down on the catch located on the top and bottom of the bezel. Remove the USB Interface (Front) Assembly from the drive connector 1 and remove the power connector 2.

  16. Locate the repair identification (RID) tag (included with the replacement Enclosure FRU). Write down the serial number of the failed 7226 Storage Enclosure unit on the RID Tag 1. Affix the RID tag to the bottom of the replacement Enclosure FRU , as close as possible, but not covering the serial number of the replacement enclosure 2.
