Replacing a subcard

CAUTION:

hen the router is operatin

, you must remove the SPE card before removin

or installin

the subcard.

Subcards do not support hot swapping. Replace a subcard using one of the following methods:

• Power off the router, and then remove or install the subcard on the SPE card.

• When the router is operating, remove the SPE card, replace the subcard on the SPE card, and

then install the SPE card to the router.

To replace a subcard when the router is powered off:

1. Put on an ESD-preventive wrist strap and loosen the captive screws on the subcard to be

replaced.

2. Pull the ejector levers outward to separate the subcard from the SPE card.

3. Slowly pull out the subcard along the guide rails, as shown in Figure 36.

4. Put the removed subcard on an antistatic mat or in the original package.

5. Gently plug the subcard (with the right side up) along the slide rails. When the ejector levers of

the subcard reach the panel of the SPE card, stop sliding the subcard. Push the panel of the

subcard and move the ejector levers of the subcard inward when the subcard reaches the SPE

card, so that the panel of the subcard is on the same plane as the panel of the SPE card.

6. Use a Phillips screwdriver to fasten the captive screws on the subcard to tighten the subcard.
