Determining A Physical Location - Cisco AIR-WLC4402-50-K9 Installation And Configuration Manual

Determining a Physical Location

Determining a Physical Location
The controller can be installed almost anywhere, it is more secure and reliable if installed in a secure
equipment room or wiring closet. For maximum reliability, mount the controller using the following
guidelines:
•
•
•
•
•
•
These distances depend on the SFP being used - refer to the Cisco SFP datasheet at

Make sure you can reach the controller and all cables.
Make sure that water or excessive moisture cannot get into the controller.
Ensure that airflow through the controller is not obstructed. Leave at least 4 inches clear on both
sides of the controller chassis.
Verify that the ambient temperature remains between 0 and 40° C (32 and 104° F).
Make sure the controller is within 328 ft. (100 m) equivalent distance 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 µm multimode fiber.
–
902 ft. (275 m) when using 200 MHz-km rated 62.5/125 µm multimode fiber.
–
– 1312 ft. (400 m) when using 400 MHz-km rated 50/125 µm multimode fiber.
– 1641 ft. (500 m) when using 500 MHz-km rated 50/125 µm multimode fiber.
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.
