Obtain and wear an ESD wrist strap on your wrist. Make sure the strap fits
snugly.
•
Attach the lead on the ESD strap to a convenient cabinet grounding point.

After removing a module from the shelf, place the module into an approved
antistatic bag or onto a grounded antistatic mat.
•
Remain grounded while installing a replacement module.
