Preparing for installation
CAUTION:
•
To avoid ESD damage to transceiver modules, network cables, or electronic components on the
device, always wear an ESD wrist strap while handling transceiver module or network cables. In
addition, make sure anti-ESD measures (such as dust prevention and temperature and humidity
maintenance) are in place at the installation site.
•
If ESD gloves are available, wear the gloves first and then the ESD wrist strap and make sure
the strap makes good contact with the glove.
To attach an ESD wrist strap:
1. Wear the strap on your wrist and fasten it securely. Make sure the strap makes good skin
contact.
2. Ground the strap reliably.

If the device has an ESD jack, connect the grounding terminal of the strap to the ESD jack,
as shown in
Figure 1 .

If the device does not have an ESD jack, clip the grounding terminal of the strap to a rack
post as shown in
Figure 2 , or take other measures to ground the strap reliably.
