Warning

Before working on a system that has an on/off switch, turn OFF the power and
unplug the power cord.

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.

Opening the Chassis

In order to upgrade Cisco 1701 router memory, you must open the chassis.
Opening the chassis requires a number one Phillips screwdriver.

Follow these steps to open the chassis:

Step 1 Make sure the router is turned off and is disconnected from the power supply.

Step 2 Turn the router upside down, and rest the top of the router on a flat surface.

Step 3 Use the Phillips screwdriver to remove the four screws that hold the top and

bottom of the chassis together, as shown in Figure C-1.

Step 5 Gently pull the top of the router (which is facing up toward you) up and away from

the bottom of the router (which is resting on the flat surface).

At this point, you might have to disconnect the fan, which is inside the top of the
router chassis, from the motherboard. Do this by disconnecting the fan cable from
the connector (labeled FAN) on the motherboard.

Step 6 Place the router bottom on an antistatic mat, and begin installing memory.
