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” on page 176.)
7. To release the DRAM module, press the plastic ejectors on both sides of the
module (see Figure 90 on page 190).
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.
