This document describes how to upgrade Flash memory and dynamic RAM (DRAM) for the following Cisco 800 series routers:
This document also describes Cisco Connection Online (CCO), which is Cisco Systems' primary, real-time support channel, and the Documentation CD-ROM, from which you can access this guide and other Cisco documentation. The Documentation CD-ROM ships with the Cisco 800 series routers and is on the World Wide Web.
The following sections are included in this document:
To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied your 800 series router. The following warning information and symbols are included:
 | Warning Only trained and qualified personnel should be allowed to install or replace this equipment. |
| Warning During this procedure, wear grounding wrist straps to avoid ESD damage. Do not touch the backplane directly with your hand or any metal tool, or you could shock yourself. |
To upgrade the Flash memory and DRAM, you must open the router chassis. You must provide a number-one Phillips screwdriver and an antistatic mat.
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, as shown in Figure 1 for all 800 series routers except the 805. Figure 2 shows the screw location for the 805 router.
Step 4 Gently pull the top of the router up and away from the bottom of the router.
Step 5 Place the router bottom on an antistatic mat.
This section describes how to upgrade the Flash memory in the Cisco 800 series routers. Check the board to see if a Flash memory module already exists. There are three upgrade possibilites:
You can order upgrade kits and have trained and qualified personnel add the Flash memory. Table 2 describes the Flash memory upgrade kits for the 800 series routers
.
| Description | Cisco Part Number |
|---|---|
4-MB Flash | MEM800-4F= |
8-MB Flash | MEM800-8F= |
Figure 3 shows where to add the Flash memory on the router motherboard for all Cisco 800 series routers except the 805 router. Figure 4 shows where to add the Flash memory on the router motherboard for the 805 router.
To upgrade the Flash memory, you must install a mini-Flash module (see Figure 5) on the router motherboard.
Follow these steps to install a mini-Flash module:
Step 1 Insert the notched edge of the module into the slot at an angle, as shown in Figure 6.
Step 2 Firmly press the unnotched edge of the module down until you hear a click.
Follow these 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 7.
Step 2 Firmly pull the release lever away from the module until the module pops up and away from the module slot.
This section describes how to upgrade the dynamic RAM (DRAM) in the Cisco 800 series routers. Check the board to see if a DRAM module already exists. There are three upgrade possibilites:
Because of the height of the actual DRAM component, you must order the additional DRAM from Cisco.
You can order upgrade kits and have trained and qualified personnel add the memory. Table 2 describes the DRAM upgrade kits for the 800 series routers
.
| Description | Cisco Part Number |
|---|---|
4-MB DRAM | MEM800-4D= |
8-MB DRAM | MEM800-8D= |
Figure 8 shows where to add the DRAM on the router motherboard for all 800 series routers except the 805 router. Figure 9 shows where to add the DRAM on the router motherboard for the 805 router.
To upgrade the DRAM, you must install the dual in-line memory module (DIMM) on the router motherboard.
Follow these steps to install a DIMM:
Step 1 If a DIMM is already installed in the slot, firmly push the slot guides away from the DIMM and down toward the motherboard, as shown in Figure 10, until the DIMM pops out of the slot.
Step 2 Insert the new DIMM into the slot, making sure that the notches on the edge of the DIMM are inserted over the bars inside the slot, as shown in Figure 11.
Only the notched edge of the DIMM fits into the slot.
Step 3 Firmly press the DIMM into the slot until the two slot guides on each side move up and over the DIMM edges, as shown in Figure 11, and you hear a click. If the guides do not move up and over the DIMM edges, move them with your hands.
Follows these steps to close the chassis:
Step 1 Place the router cover upside down with the front of the cover facing you.
Notice the two rectangular tabs near the bottom of the front cover.
Step 2 Pick up the router bottom and turn it so that it is upside down with the back panel facing away from you.
Notice the two hooks along the router bottom.
Step 3 Hold the front of the router bottom at an angle so that the hooks slip under the tabs on the front cover. (See Figure 12.)
Step 4 Lower the back end of the router bottom.
The router bottom and the bottom of the front cover should be aligned.
Step 5 Turn the router chassis over so that the back panel is facing you.
Step 6 Replace the two screws that you removed when opening the chassis. (See Figure 1 and Figure 2.)
Cisco Connection Online (CCO) is Cisco Systems' primary, real-time support channel. Maintenance customers and partners can self-register on CCO to obtain additional information and services.
Available 24 hours a day, 7 days a week, CCO provides a wealth of standard and value-added services to Cisco's customers and business partners. CCO services include product information, product documentation, software updates, release notes, technical tips, the Bug Navigator, configuration notes, brochures, descriptions of service offerings, and download access to public and authorized files.
CCO serves a wide variety of users through two interfaces that are updated and enhanced simultaneously: a character-based version and a multimedia version that resides on the World Wide Web (WWW). The character-based CCO supports Zmodem, Kermit, Xmodem, FTP, and Internet e-mail, and it is excellent for quick access to information over lower bandwidths. The WWW version of CCO provides richly formatted documents with photographs, figures, graphics, and video, as well as hyperlinks to related information.
You can access CCO in the following ways:
