Replacing Crypto Accelerator Modules on J2320 and J2350 Routers

The Crypto Accelerator Module is a processor card that enhances performance of cryptographic algorithms used in IP security (IPSec) services. The Crypto Module is an optional feature on J2320 and J2350 Services Routers.

Figure 80 shows the location of the Crypto Accelerator Module on J2320 and J2350 routers.

To remove or install a Crypto Accelerator Module, use the following procedures:

• Removing a J2320 or J2350 Crypto Accelerator Module
• Installing a J2320 or J2350 Crypto Accelerator Module

Removing a J2320 or J2350 Crypto Accelerator Module

Note: If you are installing a Crypto Accelerator Module into a J2320 or J2350 Services Router for the first time, proceed directly to Installing a J2320 or J2350 Crypto Accelerator Module.

To remove the Crypto Accelerator Module:

1. Place an electrostatic bag or antistatic mat on a flat stable surface to receive the Crypto Module.
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 Services Router. Wait for the POWER LED to turn off.
4. Unplug the power cord or cable from the power source receptacle.
5. Remove the chassis cover. (See Removing and Replacing the Chassis Cover on J2320 and J2350 Routers.)
6. Locate the Crypto Module on the system board (see Figure 80).
7. Using a Phillips screwdriver, remove the three screws from top of the Crypto Accerator Module, as shown in Figure 81.

8. Gently lift the Crypto Module to disengage it from the connector on the system board, as shown in Figure 81.
9. Place the Crypto Module on the antistatic mat or in the electrostatic bag.

Installing a J2320 or J2350 Crypto Accelerator Module

To install a Crypto Accelerator Module:

1. Take the following steps if you have not already done so:
   1. 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.
   2. Press and release the power button to power off the Services Router. Wait for the POWER LED to turn off.
   3. Unplug the power cord or cable from the power source receptacle.
   4. Remove the chassis cover. (See Removing and Replacing the Chassis Cover on J2320 and J2350 Routers.)
2. Locate the Crypto Module connector on the system board (see Figure 82).
3. Remove the Crypto Module from its electrostatic bag.
4. Align the notches in the Crypto Module with the notches in the connector on the system board and push the Crypto Module down flat, as shown in Figure 82.

5. Insert the three screws and tighten them until snug. Do not overtighten.
6. Replace the chassis cover. (See Removing and Replacing the Chassis Cover on J2320 and J2350 Routers.)
7. Replace the power cord or cable.
8. Press and release the power button to power on the router. Verify that the POWER LED lights steadily.
9. Verify that the Crypto Module is correctly installed by issuing the show chassis hardware command, as shown in the following example:
   
   

   user@host> show chassis hardware

   user@host> show chassis hardware
