ES-315-F Quick Start Guide
• SFP transceivers are equipped with a Class 1 laser, which
emits invisible radiation when the device or system is pow-
ered up. To avoid possible eye injury, do not look into an
operating fiber-optic transceiver’s connectors.
• Do not remove and install an SFP transceiver more often
than is absolutely necessary. Doing so may shorten the use-
ful life of the transceiver.
Take the following steps to attach a transceiver.
1 Disconnect all fiber-optic cables from an SFP transceiver
before installing or removing it.
2 Remove the SFP transceiver from its protective
packaging.
3 Align the SFP transceiver in front of the SFP slot opening.
