MAP1600 Section-5 (Brace extension frame, front)

Before you begin

To remove the brace extension frame from the front of the rack, do the procedure in this section.
Warning: The assembly that consists of the brace extension frame and X-braces weighs 21.5 kg (47.3 lb). This weight exceeds the safe lifting limit for a single service representative. Removal of this assembly requires two service representatives. The brace extension frame alone weighs 17.0 kg (37.4 lb). If another service representative is not available, you can remove the X-braces from the brace extension frame to lighten it and then remove the brace extension frame.

Procedure

  1. Remove seven screws Callout label 2 that secure the brace extension frame Callout label 1 to the rack.
    Note: Earlier frames have pre-threaded holes and later frames have the removable nut that will be loose once the screw is removed.
  2. Remove the brace extension frame and X-braces Callout label 3 as an assembly. See Figure 7.
  3. After the service action is complete, you must reinstall all hardware that was removed to allow service access.

MAP1600 Section-7 (Brace extension frame, rear)

Before you begin

To remove the brace extension frame from the rear of the rack, do the procedure in this section.
Warning: The assembly that consists of the brace extension frame, vertical brace, and V-braces weighs 30.6 kg (67.4 lb). This weight exceeds the safe lifting limit for a single service representative. Removal of this assembly requires two service representatives. The brace extension frame alone weighs 17.0 kg (37.4 lb). If another service representative is not available, you can remove the V-braces and the vertical brace from the brace extension frame to lighten it and then remove the brace extension frame.
