Removing a DRAM Module

To remove a DRAM module:

1. Place an electrostatic bag or antistatic mat on a flat, stable surface.
2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and connect the strap to the ESD point on the chassis, or to an outside ESD point if the router is disconnected from earth ground. For more information about ESD, see the Getting Started Guide for your router.
3. Press and release the power button to power off the router. Wait for the POWER LED to turn off.
4. Unplug the power cord or cable from the power source receptacle.
5. Remove the screws from the sides and top of the chassis that secure the cover to the chassis.
6. Slide the cover off the chassis. (For J2320 and J2350 routers, see Removing and Replacing the Chassis Cover on J2320 and J2350 Routers.)
7. To release the DRAM module, press the plastic ejectors on both sides of the module (see Figure 90).
8. Grasp the DRAM module, being careful not to touch any electrical components on the module, and firmly pull it out of the slot on the system board.
9. Place the DRAM module on the antistatic mat or in the electrostatic bag.
