C3750 Upgrade

[james.wilson1]

Morning all,

I have 2 C3750X-48 port switches stacked together, they are on IOS version 12.2(53) which I dont have to tell you is ancient :(

I would like to upgrade these switches to the latest IOS possible however when looking into my hardware and the minimum requirements I have some conflicting information...

http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3750/software/release/12-2_53_se/release/notes/OL21141.html#wp697320

The release notes for the IOS they're on suggests the minimum RAM is 512mb however as you can see below I only have 256mb, now I assume its because both switches only have 128mb RAM each but I could be wrong.

Looking at the hardware requirements for 15.0.2-SE10a and they're exactly the same so I think I should be ok to upgrade but just wanted a second opinion before doing so.

http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3750/software/release/15-0_2_se/release/notes/OL25301.html#pgfId-1042527

Also I have also read that these switches have static parts and cannot be upgraded but Cisco offers a trade in program to upgrade, is this correct and is it still available?

Thanks in advance

Hi you can move from your v12 to v15 no problem same dram and flash 256/64 so the upgrade can happen , just make sure you have enough room in flash to upload it , if not you will have to delete the current image and then apply it flash , do not let the switch reboot if there is no image in it or it will go to rommon

to check flash run command dir

it will give something like below , count from left in 6 spaces will give you the amount of free MB , as below 49mb left , do the same with your flash

#dir
Directory of flash0:/

    1  -rw-   109688280  Oct 11 2016 09:30:00 +00:00  c2951-universalk9-mz.SPA.155-3.M4.bin

256507904 bytes total (49676288 bytes free)

also verify the image when its in place make sure it did not get corrupted before applying  

verify /md5 flash:c2951-universalk9-mz.SPA.155-3.M4.bin

Also I have also read that these switches have static parts and cannot be upgraded but Cisco offers a trade in program to upgrade, is this correct and is it still available?

This im not sure of maybe someone else can answer that bit
