Attaching an ESD wrist strap
Every M9000 gateway comes with an ESD wrist strap. To minimize ESD damage to electronic
components, wear the ESD wrist strap and make sure it is correctly grounded when installing modules.
To attach an ESD wrist strap:
1. Make sure the gateway is correctly grounded. For how to ground your gateway, see " Grounding
the gateway ."
2. Put on the wrist strap.
3. Tighten the wrist strap to keep good skin contact. Make sure the resistance reading between your
body and the ground is between 1 and 10 megohms.
4. Insert the grounding terminal of the ESD wrist strap into the ESD port on the gateway chassis.
