Installing System Images
Step 3 Be sure to properly close a terminal session to avoid unauthorized access to the appliance. If a terminal
session is not stopped properly, that is, if it does not receive an exit(0) signal from the application that
initiated the session, the terminal session can remain open. When terminal sessions are not stopped
properly, authentication is not performed on the next session that is opened on the serial port.
Caution Always exit your session and return to a login prompt before terminating the application used to establish
the connection.
Caution If a connection is dropped or terminated by accident, you should reestablish the connection and exit
normally to prevent unauthorized access to the appliance.
Installing the System Images for the IPS-4240 and IPS-4255
Note This procedure is for the IPS 4240, but is also applicable to the IPS 4255. The system image for the
IPS 4255 has “4255” in the filename.
You can install the IPS 4240 and IPS 4255 system image by using the ROMMON on the appliance to
TFTP the system image onto the compact flash device. To install the IPS 4240 and IPS 4255 system
image, follow these steps:
Step 1 Download the IPS 4240 system image file to the tftp root directory of a TFTP server that is accessible
from your IPS 4240.
Note Make sure you can access the TFTP server location from the network connected to the Ethernet
port of your IPS 4240.
Step 2 Boot the IPS 4240.
