Removing a Transceiver from a QFX Series Device
The transceivers for the QFX Series are hot-removable and hot-insertable
field-replaceable units (FRUs). You can remove and replace them without powering off
the device or disrupting device functions.
Before you begin removing a transceiver from the QFX Series, ensure that you have taken
the necessary precautions for safe handling of lasers (see
“Laser and LED Safety
Guidelines and Warnings for the QFX Series” on page 120 ).
Ensure that you have the following parts and tools available:
• Antistatic bag or an antistatic mat
• Needlenose pliers
•
Rubber safety caps to cover the transceiver and fiber-optic cable connector
•
Dust cover to cover the port
To remove a transceiver from the QFX Series:
1.
Place the antistatic bag or antistatic mat on a flat, stable surface.
2.
Label the cable connected to the transceiver so that you can reconnect it correctly.
WARNING: Do not look directly into a fiber-optic transceiver or into the
ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cables
connected to transceivers emit laser light that can damage your eyes.
