Installing a DRAM DIMM in a Cisco 2811, Cisco 2821, or Cisco 2851 Router
To install a DRAM DIMM in a Cisco 2811, Cisco 2821, or Cisco 2851 router, follow these steps:
Step1 Locate the DRAM DIMM connector on the system board. See Figure 8, Figure 9, Figure 10, or
Figure 11, depending on your router model, for the location of the DIMM connectors.
Step2 Make sure that both latches on the DIMM connector are in the open position.
Step3 Orient the DIMM so that the polarization notch lines up with the polarization key on the connector. See
Figure 12.
Step4 Insert the DIMM carefully into the connector.
Step5 Carefully and firmly press the DRAM DIMM into the connector until the latches close onto the DIMM.
Make sure that both latches rotate to the closed position against the DIMM. See Figure 16.
