Solution

Resolution
Follow these steps to resolve PTP Cable Mis-Routing issue:

Field reports and internal audits have confirmed a potential problem associated with the PTP Switch Motor Cable not being routed properly in manufacturing. The mis-routed cable harness is under the mechanism deck and can short against a sharp edge in the metal chassis of the SL8500 PTP bay. The shorted out PTP cable harness can cause PTP initialization errors.

Recommendation:

Recommend the PTP assembly be pulled out of the SL8500 frame and the PTP bay inside the library be inspected per the attachments; re-route and secured the associated cable harness if necessary as illustrated in the attached.

** It should not be necessary to inspect PTP's already installed and in production, the short would typically occur soon after installation and testing.

Final Corrective action:

Corrective action was implemented 8/2006 in manufacturing and internal audits were completed.

Refer to the attached photo examples of error and photo of correct routing.
