1. Read the safety information to which Preparing to remove and replace parts refers.
2. Follow the procedure in MAP 5350: Powering off a node to verify that hosts will not lose access to data in volumes before you power off the node.
3. Slide the node out on its slide rails to the fully extended position.
   Fast path: You can perform this service procedure with the node in place. Slide the node out six inches to verify that the cover is in place, then return the node to its locked position.

   You can accomplish most service actions when the node is fully extended from the rack on its slide rails. You can leave the Fibre Channel and Ethernet cables connected, if you are using the cable-management arm and if you are not removing the node from the rack. If the location of the node in the rack is too high or too low to work comfortably, you can remove the node from the rack.

4. Optional: If you must remove the node from the rack to work on it, perform the following procedure to remove all cables and remove the node from the rack:
   1. Pull back the cable-management arm if you are working from the rear of the rack, or slide the node out of the rack to the fully extended rail position if you are working from the front.
   2. When the node is completely turned off, remove the cable-retention brackets and disconnect the power cables, as described in Removing the cable-retention bracket.
   3. To make sure that you can replace all cables in the same ports from which they were removed, label the port position of each Fibre Channel and Ethernet cable; then remove all cables from the back of the node.
   4. Remove the node from the rack and place it on a flat, static-protective surface. See Removing a node from a rack.
5. Make sure that the cover is in place and fully closed.
   Attention: To avoid damage to the disk drive connectors, make sure that the cover is in place and fully closed whenever you install or remove the hard-disk drive.
6. Remove the service controller. See Removing the service controller.

   You do not have to disconnect the service controller cable. You can suspend the service controller by its cable or rest the service controller on another surface while removing and replacing the drive.

7. Slide the orange release latch ( 1  in Figure 1) gently to the left to unlock the drive handle of the boot drive. For details on the boot drive location, see Locating the IDs for disk drives: 2145-CG8 or 2145-CF8.
