ICX7450 OS

zachary_hull

I am running ICX7450's and some of our switches were pre-maturely upgraded to 08.0.92.

I would like to know if it is possible to migrate the OS from 08.0.92 [backward] to 08.0.90.

Has anyone tried this before? Is there a procedure for this?

Please, advise.

Hey Zachary,

Yes, you can move from 8092 to 8090 with no problem. You will just use the UFI image and do something like this:

copy tftp flash <tftp-ip-addr> <8090-filename-ufi.bin> <pri/sec>

Ex.

copy tftp flash 192.168.1.100 SPS08090mcufi.bin primary

Once the copy is done, issue a 'show flash' to confirm the image is present and then go ahead and reload into the new code.

Hey Ben, thank you for the feedback.

Below is the result of the push:

SPR08090kufi.bin 100% 46MB 692.7KB/s 01:08
Connection to x.x.x.x closed by remote host.

I got on the switch:

SSH@ICX7450-24P Router>show flash
Stack unit 1:
Pri Code Flash Empty
Compressed Sec Code size = 32172120, Version:08.0.92bT213 (SPR08092b.bin)
Compressed Pri Boot Code size = 786944, Version:10.1.17T215 (spz10117)
Compressed Sec Boot Code size = 786944, Version:10.1.17T215 (spz10117)

Did you see the progress on the CLI? It may still be copying, but hard to say from that output. You can check 'show flash' again after a few minutes. If not, you may need to try it again.

I pushed the KUFI from our server. I can attempt via pulling to the switch.

Typically, pushing from the server works in this circumstance.

Show flash - still shows the primary and being empty.

Appears FIPS is unhappy...

SSH@ICX7450-24P Router#copy flash flash pri
Flash Memory Write (8192 bytes per dot)

Do you have FIPS turned on?

zachary_hull

@ben_beck

I inherited these switches from another administrator and apparently he enabled FIPS.

I didn't turn it on.

Via console > no fips enable

yes?

zachary_hull

@ben_beck

ICX7450-24P Router(config)#no fips enable
FIPS Error: System is not running in FIPS mode.

It says FIPS isn't running, but apparently it is somewhere.
