Installing FRUs
There is no required order for installing FRUs. H3C recommends that you 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 S7500E series 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.
