I always check the version of code on ALL switching and routing gear. You need to know what the bugs are and what code to avoid, if possible. I say this about all vendors (Cisco, Brocade, any and all of them). For Brocade, here are two commands below. First, see what the switch is booting to (primary or secondary code). Second, what is the code.
telnet@CoreSwitch#sh boot
Boot system preference(Configured):
Boot system flash primary
Boot system preference(Default):
Boot system flash primary
Boot system flash secondary
telnet@CoreSwitch#sh flash
Active Management Module (Slot 9):

Code Flash Free Space = 5505024
Standby Management Module (Slot 10):
Compressed Pri Code size = 4593469, Version 07.4.00fT3e3 (SXR07400f.bin)
