4Installation precautionsCAUTIONEnsure that the router does not overload the power circuits, wiring, and over-current protection.To determine the possibility of overloading the supply circuits, add the ampere (amp) ratings of allrouters installed on the same circuit as the router. Compare this total with the rating limit for thecircuit. The maximum ampere ratings are usually printed on the devices near the input powerconnectors.CAUTIONBrocade NetIron XMR 4000, 8000 16000, and 32000 routers with DC power sources areintended for installation in restricted access areas only. A restricted access area is where accesscan be gained only by service personnel through the use of a special tool, lock and key, or othermeans of security, and is controlled by the authority responsible for the location.CAUTIONBrocade NetIron XMR 32000 routers with AC power sources are intended for installation inrestricted access areas only. A restricted access area is a location where access can be gainedonly by service personnel through the use of a special tool, lock and key, or other means ofsecurity.CAUTIONFor the DC input circuit to the system of Brocade NetIron XMR 4000, 8000, and 16000 routers(1200W supply), make sure there is a 30 amp circuit breaker, minimum -48Vdc, double pole, onthe input lugs to the power supply. The input wiring for connection to the product should becopper wire,#8 AWG for 1200W power supply and #6 AWG for 1800W power supply, markedVW-1, and rated minimum 90o C.CAUTIONFor the DC input circuit to the system of a Brocade NetIron XMR 32000 router (2400W supply)make sure there is a 75 amp circuit breaker, minimum -48Vdc, double pole, on the input lugs tothe power supply. The input wiring for connection to the product should be copper wire, 4 AWG,marked VW-1, and rated minimum 90 C.CAUTIONFor the NEBS-compliant installation of a Brocade NetIron XMR 4000, 8000, and 16000 routerswith AC and DC systems, use a ground wire of at least 6 American Wire Gauge (AWG). The groundwire should have an agency-approved crimped connector (provided with the device) attached toone end, with the other end attached to building ground.
