This document contains the following sections:
 | Warning 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. |
In order to upgrade Cisco 1700 router memory, you must open the router 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 1.
Step 4 Turn the router back to its original position (right-side 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 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.
Figure 2 shows where to install DIMMs and mini-Flash modules on the router motherboard.
You can install a mini-Flash module (shown in Figure 3) to increase the amount of Flash memory in the router.
Take the following steps to install a mini-Flash module on the motherboard:
Step 1 Locate the module slot on the motherboard, shown in Figure 2.
Step 2 Hold the module with the notched edge away from you.
Step 3 Insert the module into the module slot at a 45-degree angle, as shown in Figure 4.
Step 4 Press down firmly on the module until you hear a clicking sound and the module is firmly inserted in the slot.
Take the following steps to remove a mini-Flash module:
Step 1 Insert your index finger between the mini-Flash module and the mini-Flash module release lever, as shown in Figure 5.
Step 2 Firmly pull the release lever away from the module until the module pops up and away from the module slot.
You can install a dual inline memory module (DIMM) to increase the amount of dynamic RAM (DRAM) in the router.
Take the following steps to install a DIMM on the router motherboard.
Step 1 Locate the DIMM slot on the motherboard, shown in Figure 2.
Step 2 Remove any existing DIMM by pulling the DIMM slot guides (shown in Figure 6) away from the DIMM and down toward the motherboard.
Step 3 Hold the replacement DIMM with the notched edge away from you and facing the router.
Step 4 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 6.
Step 5 Firmly press the DIMM into the slot until the two slot guides on each side of the slot move up and over the end of the DIMM, as in Figure 6. If the guides do not move up over the edge of the DIMM, move them with your hands.
After installing memory on the motherboard, follow these steps to close the chassis:
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 corresponding openings on the chassis bottom.
Step 3 Line up the posts with the corresponding openings, as shown in Figure 7, and carefully slide the posts into the openings, taking caution not to damage the router motherboard with the posts.
Step 4 Replace the screws that you removed when opening the chassis. (See Figure 1.)
