Danger: Fiber-optic equipment can emit laser or infrared light that can injure your eyes.
Never look into an optical fiber or connector port. Always assume that fiber-optic cables are
connected to a light source.
Warning:
• Ensure that the plug is inserted while you install or remove the transceiver. Only
remove the plug when you are ready to attach network cables.
• Electrostatic discharge (ESD) damage can occur if system components, including
transceivers, are mishandled. Always wear an ESD-preventive wrist or ankle strap and
always connect an ESD strap to the grounding plug on the front of the chassis.
• Always place system components on an anti-static surface.
• Avoid bending fiber-optic cable beyond its minimum 1.5 in. (3.81 cm) bend radius.
Note:
• Do not remove the dust cover on the connector until you are ready to install the
transceiver.
Always replace the dust cover when the transceiver is removed.
• Discard transceivers according to all local laws and regulations.
• Transceivers are keyed to prevent incorrect insertion.
