CMM4 device crashes

The CMM4 device crashes, apparently works OK, feeds AP Wimax equipment, responds to ping, all OK, but does not allow remote access by http. In the case that an AP has an access problem we can not restart it from CMM4 since there is no http or telnet access. Depending on the type of fault, you must go quickly on site to restart CMM4, after which you can operate remotely to restart AP’s.

Has anyone detected this same problem? Does anyone know of any way to solve it?
