Attach the Optical Network Cable
Before you begin
Before you remove the dust plugs and make any optical connections, follow these guidelines:
• Keep the protective dust plugs installed in the unplugged fiber-optic cable connectors and in the transceiver
optical bores until you are ready to make a connection.
• Inspect and clean the MPO connector end faces just before you make any connections.
• Grasp the MPO connector only by the housing to plug or unplug a fiber-optic cable.
40-Gigabit QSFP+, QSFP28, or QSFP-DD transceiver modules are keyed to prevent incorrect insertion.
