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 Specifications, at this URL: http://www.cisco.com/en/US/docs/routers/7200/install_and_upgrade/gbic_sfp_modules_install/5067g.html 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.
