The fiber optic communication channels in the single-mode OC-3c card (NTC OC3-SM) operate
with laser energy, which can be harmful, especially to the eyes. During normal operation this energy
is confined to the cable and presents no danger. To avoid injury when you are connecting or
disconnecting optical channels, observe these precautions:

Always disconnect the card from the backplane before connecting or disconnecting optical
cables.

Always keep the protective cap on the optic connector when the connector is not in use.

Never look into an optical cable or connector.

Reset Switch

The reset switch is recessed behind the faceplate to avoid accidental disturbance. It is not for
customer use.
