I have a SG500X-48P which connects to a number of SG300 via fibre ports, I have upgraded the 500 to 22.214.171.124 and now we find the switch will not boot up with the fibre modules in, it goes through the process and then comes up with a "fatal error" , then it reboots, its fine if we boot up without the fibre modules in, if we use the other (old image 1.2.7.x) it boots fine with the fibre modules in.
