MAS configuration problem on CS1K release 7.5

[atmaal5]

Hi,
I am on a CS1K release 7.5.
I have a primary UCM server configured as a deployment server with all the linux service packs updated.
I installed a CPDC card for MAS services.I installed Linux Service Pack and 2 QFE specific MAS services.
The MAS was deployed from the Primary UCM server.
In UCM i see the base manager MAS element and the link to MAS element manager (it works).
But when i try to add a node for MAS services, UCM did not see the MAS server preiously deployed, patched and so on.
On an other hand i have some difficulties to find the good NTP for MAS installation.

Thanks in advance
