Installing FRUs

There is no required order for installing FRUs. As a best practice, connect power cords after
completing installing all required FRUs.
Keep the chassis and the component packages for future use.

Attaching an ESD wrist strap

The router is provided with an ESD wrist strap. To minimize ESD damage to electronic components,
wear an ESD wrist strap and make sure it is reliably grounded when installing modules.
To use an ESD wrist strap:
1. Make sure the router is reliably grounded. For how to ground your router, see "Grounding the
router."
2. Wear the wrist strap.
3. Tighten the wrist strap to keep good skin contact. Make sure the resistance reading between
