The equipment with optical ports supports various types of optical transceivers, which are Class I laser products. Pay attention to the following:
l When an optical transceiver is working, ensure that its port is connected to an optical cable or covered by a dust cap to keep out dust and prevent it from burning your eyes.
l When an optical transceiver is working, do not stare into its port after removing the optical cable. Otherwise, your eyes may be hurt.
