Chapter 3 PIX 506/506E Replacing a Lithium Battery Replacing the Chassis Cover Caution Do not operate PIX security appliances 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. Complete the following to replace the chassis cover: Step 1 Step 2 Step 3 Step 4 Step 5 Step 6 Step 7 Step 8 Place the chassis on a secure surface with the front panel facing you. Hold the chassis cover so the tabs at the rear of the cover are aligned with the bottom of the chassis. Lower the front of the cover onto the chassis, making sure that the side tabs of the cover fit under the side panels of the chassis. Slide the chassis cover toward the front, making sure that the cover tabs fit under the back panel, and the back panel tabs fit under the chassis cover. Secure the chassis cover with the screws you set aside earlier. Reconnect the network interface cables. Place the PIX 506/506E on a flat, stable surface. The PIX 506/506E is not rack mountable. Reconnect the power cord and power on the security appliance. Replacing a Lithium Battery The PIX 506/506E has a lithium battery on its main circuit board (see Figure 3-9). This battery has an operating life of about ten years. When the battery loses its charge, the PIX security appliance cannot function. The battery is a field-replaceable unit (FRU). You can use a standard 3V lithium battery to replace the used battery. 78-15170-02 Cisco PIX Security Appliance Hardware Installation Guide 3-7
