upgrading 3750X

[icecream-guy]

What the process for upgrading 3750X stacks, these switches contain C3KX-SM-10G modules. Previously when I've upgraded the switch, the modules won't run because of the code difference, also I get incompatible software messages when I try to upgrade the modules first,  I've gotten around this in the past by consoling into the switch and upgrade the modules, but this  stack I need to upgrade is remote, with pending outage if I can't get them up on the new code directly.

According to the docs, the C3KX-SM-10G module will function in "pass-through" mode if you have a software mismatch:

The FRULink 10G Service Module (C3KX-SM-10G) software version is incompatible with the IOS software version. Please update the software. Module is in pass-thru mode.

Based on this, you should be able to upgrade the switch IOS first, followed by the 10GbE service module.

I don't know if the C3KX-SM-10G fits in a 3850. 
we've got C3850-NM-4-1G in our 3850's, which doesn't need separate upgrade
I wish I had a spare C3KX-SM-10G


thanks for the link mlan

Me:
Sips morning coffee while reading
Digs out old text file titled "Why I HATE the 3750 vol 3.txt"
Slight snicker as I add line 273
glance over list and shudder, then save/close.
quick daydream of viscous ways to destroy 3750s before I return to reality.

I have thought about using a taser on a 3750 before. Dont judge!
