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
Warning
Take care when connecting units to the supply circuit so that wiring is not overloaded.
Statement 1018
•
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.
Note
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

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.
