Note This alarm is obsolete.
Description PPDA Invalid Combination: Terminal board JPDR-[ ] present without JPDB.
Possible Cause PPDA requires that a JPDB board be connected to the PDM for each JPDR connected.
• A JPDR board is connected without a JPDB present.
• Two JPDR boards are connected with only one JPDB present.
Solution
• Verify that for each JPDR connected through ribbon cable, there is one JPDB present.
• Verify that the ToolboxST configuration matches the hardware configuration.
• Reboot the PPDA after the hardware connections are corrected.
141-145
Description Configured TB at Phy Position-[ ] doesn't match actual H/W.
Possible Cause
• The auxiliary terminal board at the specified physical position does not match the ToolboxST configuration.
• The auxiliary terminal boards have been added in the wrong order.
Solution
• Verify that the actual hardware matches the auxiliary terminal board configuration in the ToolboxST configuration.
• Verify that the auxiliary board physical position matches the Phy Pos value in the ToolboxST configuration. (Right-click
the PPDA and click Modify....)
• NOTE: JPDM and JPDC boards assume two feedback channels, so the first connected auxiliary terminal board is in Phy
Pos 2 rather than Phy Pos 1.
