Removing an Alarm Card
To remove an alarm card, see Figure 6-35 and follow these steps:
Step 1 Attach an ESD-preventive strap to your wrist and connect the leash to the chassis
or to another grounded, bare metal surface.
Step 2 Loosen the captive screw on each side of the alarm card.
Step 3 Grasp the handle on the front of the alarm card and slide the alarm card halfway
out of the slot, then stop.
Step 4 Touching only the metal card carrier, use your free hand to support the bottom of
the alarm card.
Step 5 Remove the card from the slot and place it directly into an antistatic bag or other
ESD-preventive container.
If you plan to return the defective alarm card to the factory, repackage it in the
shipping container you received with the replacement card.
