Help needed with BS-11

Hello, One of our BS-11 stations began to behave strangely. I see the following messages during boot-up: PHASE: 1 Load SMU Intended Abis-link: Down PHASE: 2 Load MBCCU MBCCU0: No Load MBCCU1: No Load Abis-link: Down PHASE: 2 Load MBCCU MBCCU0: Load BTSCAC MBCCU1: No Load Abis-link: Down PHASE: 2 Load MBCCU MBCCU0: Load BTSCAC MBCCU1: Load BTSCAC Abis-link: Down PHASE: 2 Load MBCCU MBCCU0: Load BTSCAC MBCCU1: No Load Abis-link: Down It looks like BS tries to load firmware on MBCCU1 and then gives up. I tried to delete and re-create trx1 objects using bs11_config, no result. Tried to reflash BS11, but got software load NACK, and when using —force option the software download process finishes but the boot-up message is the same as above. Does it mean that TRX1 is failed and cannot be used no more? Best Regards, Sergey.
