Replacing Crypto Accelerator Modules on J4350 and J6350 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 a standard feature on J6350 Services Routers
and an optional feature on the J4350 Services Routers.
Figure 83 shows the location
of the Crypto Accelerator Module.

Module Location on J4350 and J6350 Routers
To modify a Crypto Accelerator Module configuration, use the
following procedures:
Place an electrostatic bag or antistatic mat on
a flat stable surface to receive the Crypto Module.
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.
Press and release the power button to power off
the Services Router. Wait for the POWER LED to turn off.
Unplug the power cord or cable from the power source
receptacle.
Remove the screws from the sides and the top of
the chassis, and slide the cover off the chassis.
Locate the Crypto Module on the system board (see Figure 83).
Using a Phillips screwdriver remove the screw,
as shown in Figure 84.

or J6350 Crypto Module Screw
Pull the
white release clips on either side of the Crypto Module out to either
side, as shown in Figure 85, to tilt the Crypto Module upward.

Slide
the Crypto Module out of its socket.
Remove the standoff washer that was under the Crypto
Module.
Place the Crypto Module on the antistatic mat or
in the electrostatic bag.
Installing a J4350 or J6350 Crypto Accelerator Module
To install a Crypto Accelerator Module:
Take the following steps if you have not already
done so:
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.
Press and release the power button to power off the Services Router.
Wait for the POWER LED to turn off.
Unplug the power cord or cable from the power source receptacle.
Remove the screws from the sides and the top of the chassis,
and slide the cover off the chassis.
Locate the Crypto Module socket on the system board
(see Figure 83). The socket
is tipped up at an angle when empty.
If a screw and standoff washer are already in place
(see Figure 84), remove
them.
Remove the Crypto Module from its electrostatic
bag and insert it into the socket.
Push the Crypto Module down flat against the main
board until the release clips click into place, as shown in Figure 85.
Insert the standoff washer under the Crypto Module.
Insert the screw and tighten it until snug. Do
not overtighten.
Slide the cover onto the router, and replace and
tighten the cover screws.
Replace the power cord or cable.
Press and release the power button to power on the router. Verify
that the POWER LED lights steadily.
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
