• Your own ESD-prevention equipment or the disposable grounding wrist strap included with all upgrade
kits, FRUs, and spares
• Antistatic mat or surface, or static shielding bag
If you need additional equipment, contact a Cisco service representative for ordering information.
For information about electrostatic discharge prevention, see the “Electrostatic Discharge Prevention” section
