Hi All,

Thank you,

Based on your post, you have an extra NIC doing nothing.

1) Connect this spare NIC directly to the switch

2) Assign an IP address to the NIC (for instance: 192.168.1.1 255.255.255.0)

3) Assign an IP address to the switchport at the switch, for instance:

interface fx/x

no switchport

ip address 192.168.1.2 255.255.255.0

4) Perform the IOS upgrade by following this URL:

XModem is the one way to go.

You may want to start with a smaller image and once online, you can upgrade to the version you need. You may also want to increase the baud rate from 9600, it will go much quicker.

Hope that helps.

What's preventing you from connecting this computer to a regular switchport?

The computer is in different network(public). I got two Ethernet card. One is used for Remote desktop and console port. I am not sure, how to do in this.

Check this link. It's for a 4500, but in the 4900 guide it states to refer to this document.
