Step 5 Remove the single screw located on the bottom of the chassis (on the chassis side closest to you).
Step 6 If necessary, insert a medium flat-blade screwdriver into the slots shown in Figure 1, Part A, and gently rotate the blade so that the top and bottom sections separate slightly.
Step 7 Holding the chassis with both hands, position it as shown in Figure 1, Part B.
Step 8 Gently pull the top section away from the bottom section. (See Figure 1, Part B.) The fit is very snug. It might be necessary to work the chassis sections apart at one end and then the other until the top section is removed from the bottom section.

For operation with newer Cisco IOS software releases, it may be necessary to increase the size of Flash memory and/or main memory. These upgrades might in turn require installation of an upgraded boot ROM and an upgraded boot helper image. See Table 1 for the requirements that might apply to your system.
For memory module and software installation instructions, see the applicable procedure as follows:
If your memory upgrades require an upgraded boot ROM and an upgraded boot helper image, complete the tasks in the following order:
1. Install the boot helper software.
2. Replace the Flash memory SIMM and the boot ROM.
3. Install the Cisco IOS image(s).
Figure 2 and Figure 3 show the physical locations of the replaceable memory components.


The Cisco MC3810 and MC3810-V contains main memory that resides in a 16-, 32-, or 64-MB EDO DRAM SIMM. The Cisco MC3810-V3 main memory is in a 64-MB SDRAM DIMM. If your Cisco MC3810 has 16 MB or 32 MB of DRAM and you want to add functional modules with increased capability, it might be necessary to increase the main memory to 32 MB or 64 MB.
Table 1 summarizes the possible memory combinations for the various Cisco MC3810 series concentrators.

Your system is equipped with a nonreplaceable Flash EPROM that holds the boot helper software image, which is a subset of a Cisco IOS system code image. The boot helper has the following functions:
It is necessary to upgrade the boot helper if you are going to install Flash memory that is incompatible with the existing boot helper image, for example, if you upgrade to 32 MB of Flash memory in a Cisco MC3810 or Cisco MC3810-V chassis.
The boot helper for use with 32 MB of Flash memory in a Cisco MC3810 or Cisco MC3810-V chassis is software image mc3810-wboot-mz.bin120-6r.T4 or later.
For additional information on loading software images, see the "Loading and Maintaining System Images and Microcode" chapter in the Configuration Fundamentals Configuration Guide for Cisco IOS Release 12.1.
You normally install boot helper software by downloading an image from a TFTP server. If your existing boot helper is unbootable or does not operate with newly installed and upgraded Flash memory, you can copy a boot helper image from a PC using X-modem protocol. This procedure is described in the "Boot Helper Image Installation from a PC Using X-Modem Protocol" section.
![]() |
Note If you are going to install 32 MB of Flash memory in a Cisco MC3810 or Cisco MC3810-V chassis, Cisco recommends that you install the new boot helper image before you change the Flash SIMM. If you install the 32-MB Flash SIMM first, you will be unable to boot the Cisco IOS image, and it will be necessary to copy the new boot helper image from a PC using X-modem protocol. |
![]() |
Note If 32 MB of Flash memory is installed in a Cisco MC3810 or Cisco MC3810-V chassis, boot ROM PLCC number 17-4840-03 must be installed. |
