Solution

This alarm ( SPMB 1 not online ) can be caused by several different issues. In most cases, the cause of this alarm can be traced to hardware. Sometimes, this alarm is caused by a misconfiguration. In this case, the SPMB 1 not online alarm on a T1600 with an RE-A-2000 routing-engine was raised when em0 was found to be disabled: 

interfaces {
...
    em0 {
        description unused;
        disable;

Upon receiving this alarm and determining that em0 is disabled, you must enable em0 . The em0 on a T1600 with an RE-A-2000 routing-engine should always be up .
