136 Appendix B Installing the Metro Ethernet enhanced CPU daughter card
CAUTION
Electrostatic discharge can damage hardware.
The 8692 Series CPU modules are sensitive to static electricity. Be
aware that electrostatic discharge from your clothing or other fixtures
around you, even at levels that do not create a spark, can cause damage
to the module components.
To prevent static discharge:
— Always place each module on a grounded antistatic mat until you
are ready to perform the upgrade or leave the module in the sealed
ESD bag.
— Always wear a static discharge leash or an antistatic wrist strap to
free yourself of electrostatic charges before you touch a module.
