on the network because an electrical arc can occur. This could cause an explosion in hazardous
location installations. Be sure that power is removed from the switch and cannot be accidentally
be turned on, or verify that the area is nonhazardous before proceeding. Statement 1070
Do not remove the rubber plugs from the SFP module port or the rubber caps from the fiber-optic cable
Caution
until you are ready to connect the cable. The plugs and caps protect the SFP module ports and cables
from contamination and ambient light.
Before connecting to the SFP module, be sure that you understand the port and cabling guidelines in the
"Preparing for Installation" section on page

If the LED is off, the target device might not be turned on, there might be a cable problem, or there
might be a problem with the adapter installed in the target device. See
for solutions to cabling problems.
