Replacing a Lithium Battery
Replacing the Chassis Cover
Caution
Do not operate the PIX security appliance without the chassis cover installed. The chassis cover protects
the internal components, prevents electrical shorts, and provides proper air-flow for cooling the
electronic components.
To replace the chassis cover, perform the following steps:
Step 1
Place the chassis on a secure surface with the front panel facing you.
Step 2
Hold the chassis cover so the tabs at the rear of the chassis cover are aligned with the chassis bottom.
Step 3
Lower the front of the chassis cover onto the chassis, making sure that the chassis cover side tabs fit
under the chassis side panels.
Step 4
Slide the chassis cover toward the front, making sure that the chassis cover tabs fit under the chassis back
panel, and the back panel tabs fit under the chassis cover.
Step 5
Fasten the chassis cover with the screws you set aside earlier.
Step 6
Reinstall the chassis on a rack, wall, desktop, or table.
Step 7
Reinstall network interface cables.
Replacing a Lithium Battery
The PIX security appliance has a lithium battery on its main circuit board. This battery has an operating
life of about ten years. When the battery loses its charge, the PIX security appliance cannot function.
The lithium battery is not a field-replacable unit (FRU) for the PIX 515/515E. Contact Cisco TAC to
replace the battery.
Note
Do not attempt to replace this battery yourself.
Warning
Danger of explosion exists if the lithium battery is incorrectly replaced. Replace only with the same
or equivalent type recommended by the manufacturer. Dispose of used batteries according to the
manufacturer's instructions.
