Transceiver warnings and cautions Transceiver warnings and cautions
WARNING: WARNING:
Fiber-optic transceivers and fiber-optic cables connected to transceivers emit laser light that
can damage your eyes. To avoid eye injuries, avoid direct eye exposure to the beam from the
fiber-optic transceiver or into the ends of fiber-optic cables when they are powered-up.
CAUTION: CAUTION:
The presence of dust in transceiver ports can cause poor cable connectivity. To prevent dust from entering, install a dust
plug in an unused transceiver port.
CAUTION: CAUTION:
Supported transceivers can be hot-swapped—removed and installed while the server is powered-on. However, to
prevent potential damage to the transceiver or the fiber-optic cable, disconnect the cable from the transceiver before
hot-swapping it.
CAUTION: CAUTION:
Do not remove and install transceivers more often than is necessary. Doing so can shorten the useful life of the
transceiver.
IMPORTANT: IMPORTANT:
When you replace a transceiver with another of a different type, the server might retain selected port-specific
configuration settings that were configured for the replaced transceiver. Be sure to validate or reconfigure port settings
as required.
