Installing FRUs
There is no required order for installing FRUs. As a best practice, connect power cords after
completing installing all required FRUs. Figures for the chassis and FRUs are for illustration only.
TIP:
Keep the chassis and the component packages for future use.
Attaching an ESD wrist strap
The switch provides an ESD wrist strap. To minimize ESD damage to electronic components, wear
an ESD wrist strap and ensure that it is reliably grounded when installing modules.
To use an ESD wrist strap:
1.
Make sure the switch is reliably grounded. For how to ground your switch, see "Installing the
switch."
2.
Wear 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 ESD wrist strap into the ESD socket on the switch chassis, or attach it to the
grounding screw of the chassis with an alligator clip.
