Cisco Cisco IPS 4255 Sensor

Verify that you have access to the TFTP server by pinging it from the local Ethernet port: 

rommon> ping server_ip_address

rommon> ping server

Specify the filename on the TFTP file server from which you are downloading the image:

rommon> file filename

Example: 

rommon> file IDS-4215-bios-5.1.7-rom-1.4.bin

The syntax of the file location depends on the type of TFTP server used. Contact your system or 
network administrator for the appropriate syntax if the above format does not work.

Download and run the update utility:

rommon> tftp

Enter 

 at the upgrade prompt and the update is executed. 

The IDS 4215 reboots when the update is complete.

Do not remove power to the IDS 4215 during the update process, otherwise the upgrade can get 
corrupted. If this occurs, the IDS 4215 will be unusable and require an RMA.
