Installing Frus; Attaching An Esd Wrist Strap; Installing Cards - H3C S7500X Series Installation Manual

Installing FRUs

WARNING!
Do not install the switch, modules, and cables when the switch has power.
There is no required order for installing FRUs. As a best practice, connect power cords after you
complete FRU installations.
The chassis and module views in the figures in this section are for illustration only.
IMPORTANT:
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.
