Virtual Private Network Modules

This appendix tells how to install or upgrade memory and how to install a Virtual
Private Memory (VPN) module in your Cisco 1701 router and includes the
following sections:

• Safety Warnings

• Opening the Chassis

• Locating Modules

• Installing a DIMM

• Installing a VPN Module

• Closing the Chassis

Warning

OL-3954-02

During this procedure, wear grounding wrist straps to avoid ESD damage to the
router. Do not directly touch the backplane with your hand or any metal tool, or
you could shock yourself.

Only trained and qualified personnel should be allowed to install or replace this
equipment.

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.

Top of router

Turn the router back to its original position (top up).

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.

Installing a DIMM

You can install a DIMM to increase the amount of dynamic random-access
memory (DRAM) in the router.

Follow these steps to install a DIMM on the router motherboard:

Step 1 Locate the DIMM slot on the motherboard.

Step 2 Remove any existing DIMM by pulling the DIMM slot guides (shown in

Figure C-3) away from the DIMM and down toward the motherboard.

Step 3 Insert the DIMM into the DIMM slot, making sure that the notches on the edge of

the DIMM are inserted over the bars inside the DIMM slot, as in Figure C-3.

Step 4 Firmly press the DIMM into the slot until the two DIMM slot guides on each side

of the slot move up and over the end of the DIMM, as in Figure C-3. If the guides
do not move up over the edge of the DIMM, move them with your hands.

Closing the Chassis

After installing memory or a VPN module on the motherboard, close the chassis
by following these steps:

Step 1 If you disconnected the fan from the motherboard as described in the “Opening

the Chassis” section, reconnect the fan cable to the connector labeled FAN on the

motherboard.

Step 2 Locate the posts that protrude from the inside of the chassis cover, and locate the

corresponding openings on the chassis bottom.

Step 3 Line up the posts with the corresponding openings, as shown in Figure C-8, and

carefully slide the posts into the openings, taking care not to damage the router
motherboard with the posts.
