Warning Class 1 laser product. Statement 1008
Caution Do not remove the rubber plugs from the XENPAK module ports or the rubber
caps from the fiber-optic cable until you are ready to connect the cable. The plugs
and caps protect the XENPAK module ports and cables from contamination and
ambient light.
Note The 10-Gigabit Ethernet XENPAK modules are referred to as 10-Gigabit Ethernet
module ports in the switch software documentation.
Note Make sure that the XENPAK module is fully inserted into the module slot and that
the captive installation screws are fully tightened before attaching the fiber-optic
interface cable connector to the XENPAK module connector.
