Make sure that water or excessive moisture cannot get into the controller.
Make sure that the controller is within 328 ft. (100 m) of equipment connected to a 1000BASE-T 
port.
Make sure the controller is within one of the following distances of equipment connected to the 
optional 1000BASE-SX or -LX port:
722 ft. (220 m) when using 160 MHz-km rated 62.5/125 um multimode fiber.
902 ft. (275 m) when using 200 MHz-km rated 62.5/125 um multimode fiber.
1312 ft. (400 m) when using 400 MHz-km rated 50/125 um multimode fiber.
1641 ft. (500 m) when using 500 MHz-km rated 50/125 um multimode fiber.
Note
These distances depend on the small form factor pluggable (SFP) gigabit converter being 
used. See the Gigabit Interface Converter (GBIC) Module and Small Form-Factor 
Pluggable (SFP) GBIC Module Installation Information and Specifications at 
.
The 1000BASE-SX SFP modules provide 1000 Mbps wired connections to a network through 
850nM (SX) fiber-optic links using LC physical connectors. The 1000BASE-LX SFP modules 
provide 1000 Mbps wired connections to a network through 1300nM (LX/LH) fiber- optic links 
using LC physical connectors.
Installing the Chassis
The controller ships with rack mounting ears attached and the desktop or shelf mounting rubber feet 
in a separate bag. Follow these guidelines when mounting the controller:
When mounting the controller on a desktop or shelf, attach the rubber feet to the bottom of the 
controller chassis, and place the chassis on any secure horizontal surface. If desired, you can 
remove the rack mounting ears from the controller.
When mounting the controller in an EIA standard rack, attach the ears to the equipment rack 
using the factory supplied fasteners.
Caution
The controller weighs 15.2 lbs (6.95 kg). For safety, two or more people must work 
together to perform the rack mount installation.
Install the SFP modules as described in the 1000BASE-SX, 1000BASE-LX, and 1000BASE-T SFP
