3com superstack 2 3300 firmware failed - hung

bringiton521 · Jan 17, 2003

Hi,
I was updating the firmware on a superstack 2 3300 switch from version 2.10 to 2.69. All went fine during the upgrade, the tftp said successful. Unfortunatley the switch hung upon reboot.
Now I can't get back into the console. Unit's light 2 and 6 stays lit upon post.
I don't have any support warranty. Were a healthcare facility, strap for cash. Is there anything worth trying before I send it in for repair.
Any suggestion would be great.

Hi,

You can try to do a serial download.
You can find the utility software on the 3Com web site.

Regards,

Luc.

Hi,

If you remain the ip address of the product, Try to connect it by telnet or by the web manager.

If it's working, you have only to change the obtain ip config to manual mode, and restart your product.

If that no work, you can try to use a DHCP server.

Hope that can help you,

Regards.
