Removing orange shipping brackets

Procedure

Remove the shipping brackets mounted on the system processor card assemblies and system processor voltage regulator cards. See Figure 1.
Figure 1. Shipping brackets - system processor card assembly and system processor voltage regulator cards (front of CEC)
1. First, remove the thumbscrews (might require a screwdriver if tight), then slide out the brackets and finger assemblies.
2. Do not discard the shipping brackets and finger assemblies. Reassemble them and store them in the document enclosure (upper left at the front of the rack).
  Note: To remove the shipping bracket from the lower system processor assembly, it might be necessary to remove the hold-down bracket from the upper pair of I/O enclosures (rB1, rB2). See Figure 2.

Remove the orange shipping bracket from the rear of each CEC enclosure to prevent the CECs from overheating.
1. At the front of Rack-1 above the CEC enclosures, slide the management console ThinkPad laptop drawer out to the service position. This allows access to the T-bracket mounting screws for the upper CEC.
2. At the rear of Rack-1, first loosen the T-bracket screws to allow the T-bracket to drop clear of the power supplies, then remove the entire bracket assembly. It is not necessary to completely remove the T-bracket. See Figure 3.

3. Do not discard the shipping brackets, store them in the open space inside the rear of the rack beneath the lower CEC enclosure or in the document enclosure (upper left at the front of the rack).
If there is an orange shipping bracket at the rear of a storage enclosure, remove it.
1. At the rear of the rack, remove the nylock nut 1 that attaches the orange shipping bracket to the left and right horizontal rails. See Figure 5.
2. Slide the bracket away from the storage enclosure so the middle support cross pin 2 disengages from the slot. See Figure 5.
3. If possible, store the brackets and nylock nuts for future use when the rack is shipped back to IBM® or another destination.
