Replacing Internal Compact Flashes on J4350 and J6350 Routers

The internal compact flash is installed in a slot on the bottom of the J4350 or J6350 chassis (see Figure 66).

Note: Use only compact flash cards purchased from Juniper Networks for your J Series platform and model.

On some J4350 and J6350 Services Routers, the compact flash is in a horizontal position, while on others it is in a vertical position. Figure 67 shows the alternative horizontal orientation of the compact flash.

To replace the compact flash:

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 Preventing Electrostatic Discharge Damage.
3. Press and release the power button to power off the router. Wait for the POWER LED to turn off.
4. Remove 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.

   Warning: If the fans are still rotating, wait until they stop before proceeding with the next step, especially if your compact flash is in the horizontal position (flat against the system board).

7. Slide the compact flash out of its slot, as shown in Figure 68.

8. Place the compact flash on the antistatic mat or in the electrostatic bag.
9. Slide the new compact flash into the slot and press down, as shown in Figure 69.

   Note: On some Services Routers the compact flash is in a horizontal position. If the compact flash connection is horizontal, lay the compact flash behind the slot and slide it forward until it clicks into place.

10. Slide the cover onto the chassis.
11. Replace and tighten the screws on the sides and top of the chassis that secure the cover to the chassis.
12. Replace the power cord or cable.
13. Press and release the power button to power on the router. Verify that the POWER LED lights steadily.
