See Figure 3-4.
In this menu, two options are available to run diagnostics:
Notes:
1. CDG to run diagnostics in concurrent diag-
nostics mode.
Selected diagnostics will run if the adapter is
available (ask the customer to disconnect the
related resources), and only the sections or
routines allowed to run in concurrent mode will
be called without interfering the 3745 opera-
tion.
For channel diagnostics:
Diagnostics must be used in CDG mode if
more than one CA is present and if CCU +
NCP are running. If it is not the case, use
ODG.
2. ODG to run diagnostics in offline mode when
the 3745 is fully available for maintenance.
Selected diagnostics will run whatever the
status of the adapter.
For channel diagnostics, all the channel inter-
faces must be disabled.
ODG must be used if conditions for concurrent
maintenance mode are not met (no NCP or
CCU running).
Based on the previous notes, Type ODG or CDG after ===> and press SEND.
