Accessing the System Board Accessing the System Board You must open the chassis to access the system board. Removing the Chassis Cover on Cisco 261x, Cisco 262x, Cisco 265x, and Cisco 26xxXM This section describes the procedure for opening the chassis by removing the chassis cover. Warning Do not touch the power supply when the power cord is connected. For systems with a power switch, line voltages are present within the power supply even when the power switch is OFF and the power cord is connected.
Accessing the System Board Warning Before opening the chassis, disconnect the telephone-network cables to avoid contact with telephone-network voltages. To see translations of the various warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device. Step 3 Attach an ESD-preventive wrist strap and ensure that it makes good contact with your skin.
Accessing the System Board Removing the Chassis Cover on Cisco 2691 Complete the following procedure to remove the chassis cover: Step 1 Power OFF the router and unplug the AC power cord. Step 2 Disconnect all network interface cables from the rear panel. Warning Before opening the chassis, disconnect the telephone-network cables to avoid contact with telephone-network voltages.
Upgrading DRAM Figure 3 Removing the Cisco 2691 Router Cover 2 62482 1 Upgrading DRAM This section describes how to upgrade dynamic random-access memory (DRAM) on the system card. You might need to upgrade DRAM for the following reasons: • You have upgraded to a new Cisco IOS software feature set or release. • You are using very large routing tables or many protocols (for example, when the router is set up as part of both a large external network and your internal network).
Upgrading DRAM Memory Capacities Cisco 2600 series routers use two types of dynamic memory: Caution • 5V EDO DRAM DIMMs (Cisco 2610, Cisco 2611, Cisco 2612, Cisco 2613, Cisco 2620, and Cisco 2621 routers) • 3.3V SDRAM DIMMs (Cisco 26xxXM, Cisco 2650, Cisco 2651, and Cisco 2691 routers) EDO DRAM and SDRAM DIMMs are not interchangeable. Although it is mechanically possible to install an incorrect DRAM DIMM into a router, the router will not boot.
Upgrading DRAM Caution It is critical that the correct voltage DRAM modules be installed in the Cisco 2600 series routers. Using the incorrect memory will cause the system to malfunction and may cause damage to the system board or memory card. For memory voltage requirements, see Table 1. To identify a 3.3V 100-pin SDRAM memory module, look for the part number label on the front of the card. (See Figure 4.) Table 2 and Table 3 show the part numbers for the memory modules. Figure 4 Cisco 2600 Series 3.

Step 2 Attach an ESD-preventive wrist strap and ensure that it makes good contact with your skin. Connect the equipment end of the wrist strap to the metal back plate of the chassis.
Upgrading DRAM Step 6 Note Position the new DIMM so that the polarization notch is located at the left end of the DIMM socket as shown in Figure 6. Make sure the new DIMM is the correct type, EDO or SDRAM, for your router. (See Table 1.) Figure 6 Removing and Replacing the 100-Pjn DRAM DIMM 1 2 A 1 4 3 B 72277 3 Step 7 Insert the new DRAM DIMM by sliding the end with the metal fingers into the DIMM connector socket at approximately a 90º angle to the system card.
Upgrading DRAM Cisco 2691 This section describes how to upgrade synchronous dynamic random access memory (SDRAM) dual in-line memory modules (DIMMs) in the Cisco 2691 routers. The Cisco 2691 router contains two 168-pin DIMM sockets for SDRAM. Each socket can be filled with a single 64-bit-wide, 168-pin SDRAM DIMM. You can configure SDRAM as a mixture of main memory, which is reserved for the CPU, and shared memory, which is used for data transmitted or received by modules and WAN interface cards.

Connect the equipment end of the wrist strap to the metal back plate of the chassis. Step 2 On the system board, locate the SDRAM DIMM sockets shown in Figure 7. Caution Step 3 Handle DIMMs by the edges only.
Upgrading DRAM Figure 9 Removing and Installing SDRAM DIMMs on the Cisco 2691 2 1 17943 2 Locking spring clips Step 4 Hold the DIMM by the edges with your thumb and index finger and lift it out of the socket, as shown in step 1 of Figure 9. Place the removed DIMM in an antistatic bag to protect it from ESD damage. Step 5 If necessary, repeat Step 3 and Step 4 for the other DIMM.
Replacing Flash Memory Step 4 Beginning with socket 0, insert the DIMM perpendicular to the socket. Push firmly into place, as shown in step 1 of Figure 9. When the DIMM is properly seated, the socket guide posts fit through the alignment holes, and the locking spring clips click into place, as shown in step 2 of Figure 9. Step 5 Ensure that each DIMM is straight (perpendicular to the socket). (See Figure 9.
Replacing Flash Memory Note Cisco 2650 and Cisco 2651 routers support a maximum of 32 MB of Flash memory. The Cisco 2620 and Cisco 2621 can be upgraded to support a maximum of 32 MB of Flash memory when using both the Cisco 2600 boot ROM version 12.2(6r) (supplied with Cisco part number MEM2620-32FSBoot=) and either Cisco IOS Release 12.1(3)T or Cisco IOS Release 12.2T or later Cisco IOS releases. The 32 MB Flash SIMM module is not supported on the Cisco 2610, Cisco 2611, Cisco 2612, or Cisco 2612.
Replacing Flash Memory To identify a SIMM module, look for the part number label on the front of the module. (See Figure 10.) Table 6 and Table 7 show the part numbers for the SIMM modules. Figure 10 Cisco 2600 Series 3.3 and 5V 80-Pin SIMM Module 72187 16-2462-02 Part number Table 6 3.3V SIMM Module Part Numbers Memory Size 3.
Replacing Flash Memory Figure 11 Removing and Replacing the System-Code SIMM Tab SIMM Tab 10244 SIMM connector (on motherboard) Step 8 Position the new SIMM so that the polarization notch is located at the left end of the SIMM socket. Caution To prevent damage, note that some Flash memory SIMMs have the components mounted on the rear side; therefore, when inserting the SIMM, always use the polarization notch as a reference and not the position of the components on the SIMM.

Replacing the Boot ROM Replacing the Boot ROM Cisco 261x, Cisco 262x, Cisco 265x, and Cisco 26xxXM Routers Note 32 MB Flash memory support is limited to the Cisco 2620(XM), Cisco 2621(XM), Cisco 2650(XM) and Cisco 2651(XM). The Cisco 261x (2610, 2611, 2612 and 2613) cannot be upgraded to support 32 MB of Flash regardless of the boot ROM version. To upgrade the router ROM software to a new ROM monitor version, you must replace the existing ROM.

To straighten out a bent pin, use needlenose pliers. Align the notch in the new ROM with the notch in the ROM socket, ignoring the orientation of the label.
Replacing the Boot ROM Testing ROM Installation Tip Before testing your ROM installation, close the router chassis using the procedure provided in the “Closing the Chassis” section on page 34. Test your installation by rebooting the router. If you installed the ROM correctly, the router will boot into the ROM monitor or operating system. If you suspect that the ROM is inserted incorrectly, remove and reinstall the ROM as described in the “Replacing the Boot ROM” section on page 29.

Closing the Chassis Step 5 Reinstall the chassis on the wall, rack, desktop, or table. Step 6 Reconnect all cables. If the router uses a DC power supply, switch the circuit breaker to the ON position. Replacing the Chassis Cover on Cisco 2691 Step 1 Place the chassis bottom so the front panel is closest to you. Step 2 Hold the cover so the tabs at the rear of the cover are aligned with the chassis bottom.
