Switch issues

[Saint George]

Newbie here,
Looking for advice.
I have a 26 port AC switch one of the Techs dropped off. Not sure what the original issue was but now.

I log in and get the lost communication error message, Default IP.

Reset button does not work.

Have recovered if with recovery tool and to firmware 1.56.

Can log in via ssh.

Can upload firmware from gui but make no changes.

Only ports 1-12 work.

Any ideas?
Rgds & confused.

Can you use putty to look at the console and run the command:

Code: Select all

show status


And paste the results here?

[Saint George]

No results when command applied.

Other show commands return info, ie vlan & configuration.

Firmware 1.5.6 in place but tried 8 & 9.
Thx

In Putty over a serial cable, try running the following commands:

Code: Select all

cmd
strings /dev/mtd1


And let me know the results.

[Saint George]

Capture attached, not much to see. I guess its heading to the dustbin. Thx

[Stephen]

If you are still in the linux terminal try running this

Code: Select all

exit
reload defaults


Note, if it works the switch will be back at 192.168.1.20

Tried that before, just done again. No change switch reset. Thanks

If it's still not behaving properly then I'm lead to believe that there must be some hardware damage on the unit. So it will have to be RMA'd
