Backplane of our BSR64K is a little damaged, but each card (SRM4, 2*TX32, HSIM) seems to boot normally (seen on serial port of each).
SRM has detected each card as I/O RM module with an x, but doesn't detect the type of card.
SRM is resetting regularly the HSIM and the two TX32 cards, with ipc problems.
you need to post a show chassis stat and show version, double check the md5 of the boot image to make sure it's good. you need to put in more information to get the right answer
