CAUTION:
When you install or remove an interface card, note the following guidelines:

Do not use excessive force in the operation and do not touch the surface-mounted
components directly with your hands.
•
After removing an interface card, if the slot is to remain empty, install a filler panel to
prevent dust and ensure normal ventilation in the switch.
Verifying the installation
During the installation of the switch, always verify the installation before powering on the switch:
•
The power supply system meets the switch requirements.
•
The grounding cable is correctly connected.
•
Both the console cable and power cords are correctly connected.
•
All interface cables are routed indoors. If outdoor routing of cables cannot be avoided, check that
network port lightning arrestors and an AC power supply lightning arresters have been correctly
installed. For more information, see the chapters “Appendix B Transceiver module specifications”
and “Appendix C Installing a lightning arrester for a network interface.”
