Command:
The information within a standalone mode display is used in the Packet Bus Fault Correction procedures
that follow. The TN771 display indicates the specific leads on the backplane to examine for bent or
damaged pins. Figure 75, Packet bus leads on the backplane (front),

NOTE:
This information is available only from the standalone mode and with an on-site
connected terminal. This information is not available from the Manager I, and, thus, it is
not available remotely. This is not a concern, inasmuch as this information cannot be used
effectively if testing is not on site.
