Gigabit Ethernet High-Speed WAN Interface Cards Cisco Gigabit Ethernet High-Speed WAN Interface Cards Laser Safety Guidelines Optical SFPs use a small laser to generate the fiber-optic signal. Keep the optical transmit and receive ports covered whenever a cable is not connected to the port. The interface card faceplate carries a Class 1 laser warning label. (See Figure 115.) Figure 115 Class 1 Laser Warning Label CLASS 1 LASER PRODUCT LASERPRODUKT DER KLASSE 1 PRODUIT LASER DE CLASSE 1 PRODUCTO LASER CLASE 1 1 HWIC1GE-SFP CLASS 1 LASER PRODUCT LASERPRODUKT DER KLASSE 1 PRODUIT LASER DE CLASSE 1 PRODUCTO LASER CLASE 1 1 EN LINK TX RX GE 0 103083 Warning Because invisible laser radiation may be emitted from the aperture of the port when no fiber cable is connected, avoid exposure to laser radiation and do not stare into open apertures. Statement 125 Warning Ultimate disposal of this product should be handled according to all national laws and regulations. Statement 1040 Cisco Gigabit Ethernet High-Speed WAN Interface Card LEDs The Cisco Gigabit Ethernet high-speed WAN interface card uses LEDs to indicate card status and activity. (See Figure 116.)
