Do not work on the system or connect or disconnect cables during periods of
lightning activity.
Read the installation instructions before you connect the system to its power
source.
Before working on equipment that is connected to power lines, remove jewelry
(including rings, necklaces, and watches). Metal objects will heat up when
connected to power and ground and can cause serious burns or weld the metal
object to the terminals.
Hazardous network voltages are present in WAN ports regardless of whether
power to the router is OFF or ON. To avoid electric shock, use caution when
working near WAN ports. When detaching cables, detach the end away from
the router first.
In order to upgrade the Cisco 815 integrated services router memory, you must
open the chassis. Opening the chassis requires a number one Phillips screwdriver.
Follow these steps to open the chassis:
Make sure the router is turned off and is disconnected from the power supply.
Turn the router upside down, and rest the top of the router on a flat surface.
Use the number one Phillips screwdriver to remove the four screws that fasten the
top and bottom of the chassis together, as shown in
Installing and Upgrading Memory and Virtual Private Network Modules
