• Cable Routing Design
• The routing of the CAB to CDD discharge cables is
  still in evolution
• Avoidance of or protection in EVA zones.
• Clamping and structural support requirements, as
  defined by NASA.
• This has added significant complexity to routing,
  as well as weight for support brackets.
• The cable to CDD interface design, and the
  routing holes in the cover have been modified.
• New drawings should be available 1 week after all
  routing issues are resolved.

• Testing
• QM test requirements have been identified and
  delivered to CSIST.
• Fasteners for CDD QM and FMs have been sent, due
  at CSIST the week of April 3, 2006. Spares to
  follow 3 to 4 weeks.
• Test hardware / requirements might have to be
  re-evaluated based upon the cable routing design
  changes.
• A test plan and schedule will be completed by
  CSIST, and reviewed by ESCG and MIT.
