Unpacking and Installing the Controller
Choosing a Physical Location
You can install the controller almost anywhere, but it is more secure and reliable if you install it in a
secure equipment room or wiring closet. For maximum reliability, mount the controller using the
following guidelines:
Warning To prevent the system from overheating, do not operate it in an area that exceeds the maximum
recommended ambient temperature of:
104° F (40° C) Statement 1047
Warning To prevent airflow restriction, allow clearance around the ventilation openings to be at least:
4 in (10.16 cm) Statement 1076
Take care when connecting units to the supply circuit so that wiring is not overloaded. Statement 1018

Note
The 1000BASE-SX SFP modules provide a 1000-Mb/s wired connection to a network through an 850nM
(SX) fiber-optic link using an LC physical connector. The 1000BASE-LX SFP modules provide a
1000-Mb/s wired connection to a network through a 1300 nM (LX/LH) fiber-optic link using an LC
physical connector. The 1000BASE-T SFP modules provide a 1000-Mb/s wired connection to a network
through a copper link using an RJ-45 physical connector.

Make sure you can reach the controller and all cables attached to it.
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 that 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.
–
These distances depend on the small form factor pluggable (SFP) gigabit converter being used
(GLC-SX-MM, SFP-GE-T, or GLC-LH-SM). Refer to the Gigabit Interface Converter (GBIC)
Module and Small Form-Factor Pluggable (SFP) GBIC Module Installation Information and
