3Installation precautionsCAUTIONEnsure that the device 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 alldevices installed on the same circuit as the device. Compare this total with the rating limit for thecircuit. The maximum ampere ratings are usually printed on the devices near the input powerconnectors.CAUTIONBrocade MLX 4-, 8-, 16-, and 32-slot devices with DC power sources are intended for installationin restricted access areas only. A restricted access area is where access can be gained only byservice personnel through the use of a special tool, lock and key, or other means of security, andis controlled by the authority responsible for the location.CAUTIONAll devices with AC power sources are intended for installation in restricted access areas only. Arestricted access area is a location where access can be gained only by service personnelthrough the use of a special tool, lock and key, or other means of security.CAUTIONFor the DC input circuit to the system of Brocade MLX-4, MLX-8 and MLX-16 routers (1200Wsupply), make sure there is a 40 amp circuit breaker, minimum -48VDC, double pole, on the inputlugs to the power supply. The input wiring for connection to the product should be copper wire, 8AWG, marked VW-1, and rated minimum 90 C.CAUTIONFor the DC input circuit to the system of a Brocade MLX-32 router (2400W supply), make surethere is a 75 amp circuit breaker, minimum -48VDC, double pole, on the input lugs to the powersupply. The input wiring for connection to the product should be copper wire, 4 AWG, markedVW-1, and rated minimum 90 C.CAUTIONFor the NEBS-compliant installation of Brocade MLXe-4, Brocade MLXe--8, and Brocade MLXe-16routers with AC and DC systems, use a ground wire of at least 6 American Wire Gauge (AWG). Theground wire should have an agency-approved crimped connector (provided with the device)attached to one end, with the other end attached to building ground. The connector must becrimped with the proper tool, allowing it to be connected to both ground screws on the enclosure.Before crimping the ground wire into the provided ground lug, ensure the bare copper wire hasbeen cleaned and antioxidant is applied to the bare wire.150 Brocade MLX Series and Brocade NetIron XMR Hardware Installation Guide53-1002373-02
