Warning and Safety Information
To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information (RCSI) document that accompanied your Cisco router. The following warning information is included in the RCSI:
Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment.
Statement 1030
Warning During this procedure, wear grounding wrist straps to avoid ESD damage to the card. Do not directly touch the backplane with your hand or any metal tool, or you could shock yourself. Statement 94
Opening the Chassis
To upgrade the flash memory and dynamic RAM (DRAM), you must open the router chassis. You must provide a number 1 Phillips screwdriver and an antistatic mat.
The model shown in the following procedure is a Cisco 804 router, but the other Cisco 800 series routers are similar to it. Follow these steps to open the chassis:
Step 1 Make sure that the power switch is turned to standby and that the power supply cable is disconnected.
Step 2 Disconnect all cables from the router back panel.
Step 3 Use the Phillips screwdriver to remove the two screws. Figure 1 shows the chassis screw locations. The chassis screw locations are the same on all Cisco 800 series routers.

Step 4 Gently push the top of the router away from you and then lift it up from the bottom of the router.
Step 5 Place the router bottom on an antistatic mat.

Upgrading the Flash Memory
Upgrading the Flash Memory
This section describes how to upgrade the flash memory in a Cisco 800 series router.
Note The Cisco SOHO series routers do not support flash and StrataFlash memory upgrade.
Table 1 shows the flash memory options for each Cisco 800 series router platform.
