Installing FRUs
There is no required order for installing FRUs. H3C recommends that you connect power cords after
completing installing all required FRUs.
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 it is well grounded when installing modules.
To use an ESD wrist strap:
1. Make sure the switch is well 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. As shown in Figure 19 , insert the ESD wrist strap into the ESD port on the switch chassis, or attach
it to the grounding screw of the chassis with an alligator clip.
