DRAM DIMM Installation
To install the DRAM DIMMs:
Step 1 Power OFF the router.
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.
Step 3 Open the cover following the instructions in the “Removing the Chassis Cover” section on page 2.
Step 4 Begin removing the existing DRAM DIMM by pulling outward on the connectors to unlatch them, as
shown in step 1 of part A in Figure 6. Be careful not to break the holders on the DIMM connector.
Step 5 Remove the existing DRAM DIMM by pulling the module straight up, as shown in step 2 of part A in
Figure 6.
Caution To prevent damage, do not press on the center of the DIMMs. Handle each DIMM carefully.
