As Duke mentioned, you may need to boot in to router code (SPR). If you do a "show flash", you may already have a router image in secondary. You can boot to it once with "boot system flash secondary" at privileged exec. You can also make that the permanent boot preference by issuing the same command from global config mode (conf t). If you need router code, you can download it in the support portal.

Ben and Duke, That's working now, thanks you so much for fast reply!! Booting from sec code..
telnet@DIST-BRU(config)#show version Copyright (c) 1996-2016 Brocade Communications Systems, Inc. All rights reserved. UNIT 1: compiled on May 19 2016 at 01:44:58 labeled as SPR08030h (31678660 bytes) from Secondary SPR08030h.bin
The above SPR makes it Layer-3 "Routing" code. SPS is Layer-2 or "Switch" code.
If I were to change this device to boot Primary, it would boot SPR08080ca.bin
By convention for Ruckus ICX, Brocade, Foundry, and other FastIron based switches, it is by convention when running Layer-3 code we boot from the secondary. They ship new in box with Switch code in the primary slot and Routing Code in the Secondary slot (if you buy a layer-3 capable device).
In the case of mine above, you will notice that I have routing code in both the primary and secondary slots... that Primary is simply an older build. This is because when I upgrade the firmware, I backup the existing code to other slot. In this case when I upgraded SPR code from 08.0.80ca to 08.0.80d, I ran the command "copy flash flash primary." Once verified complete I used "verif md5 pri" to validate the MD5 checksum to ensure the backup image is intact in the unlikely event it is needed! At that point, I upgraded the bootrom and copied SPR for 08.0.80d to Secondary. I also checked the checksum on the new secondary.
If I was updating switch code such as SPS code, I would by convention be booting from Primary (I leave it set to default) for this. If I was doing a backup, I would copy Primary => Secondary to back switch code up.
The reasoning is that if there is a problem, with a console cable you can get to the boot-monitor and booth whichever slot you want. In the event something goes wrong and the device fails to boot up, it would almost certainly boot to boot-monitor. Otherwise, it would be in a boot-loop that could be interrupted by pressing "b" when prompted.
Hope that helps. I know it is a lot of info, but it is the why, the how, and the reasoning.
*knocks on wood* I have never had an ICX device fail to boot after a firmware upgrade!
