ATT System 25 Installation And Maintenance Manual

INSTALLATION
Cold and warm starts both display the same type of information on the SAT. This
consists of a listing of the version of the firmware loaded in the CPU/Memory
CP, followed by a configuration listing of all CPs recognized by the system. The
CPU/Memory CP is not in the configuration listing; however, it is located in slot 1
of Cabinet 1.
Table 2-C provides a listing of SAT messages

INSTALLATION
The SAT message for a cold or warm start appears after the system has
performed all self-tests and reading of its configuration. Typical cold start SAT
message is as follows. The example is for a 2-cabinet system.

INSTALLATION
Check Performance of Cabinet Components
Each CP has three colored LEDs on the front panel that indicate whether it is
functioning properly or not.When a cold start is performed, the system
undergoes a series of self-tests and loads default translations.
Upon initial power application, each CP tests itself. The red LED on the CP
lights to indicate that the test is in progress. Once the CP passes its initial
tests, the red LED goes off. Then, after the main processor recognizes the
CP and can...

INSTALLATION
If all the CPs are operating properly, only the green LED on the CPU/Memory CP
and the amber LED on the Service Circuit should be flashing. If any other CP
has a no-lighted LED, the CP may need to be reseated. All port CPs green LED
remains dark until at least one port on the CP has been translated.
Except for the CPU/Memory CP and Service Circuit CPs, power can be left on
while a CP is reseated. To reseat a CP, do the following:

Instructions
for initializing the system(based on the completed
implementationforms) are provided in the Administration Manual
(555-540-500).
Note:Before trunks using DS1 Signaling are administered, all link
level parameters such as signaling and framing and all link
level alarms must be cleared. If this is not possible, PBXs at
each end will not work.If this condition exists, clear a
maintenance busy condition that exists at each end.
