Removing the Chassis Cover
To remove the chassis cover, perform the following steps:
Note Removing the PIX security appliance case does not affect your Cisco warranty. Upgrading the
PIX security appliance does not require any special tools and does not create any radio frequency leaks.
Step 1 Read the Regulatory Compliance and Safety Information document.
Step 2 Ensure that the PIX security appliance is powered off. Unplug the power cord from the power outlet.
Once the upgrade is complete, you can safely reconnect the power cord.
Warning
Before working on a system that has an On/Off switch, turn OFF the power and unplug the power cord.
Step 3 Remove the three screws holding the chassis cover in place, as shown in Figure 5-11.
