Installation precautions
CAUTION
Ensure 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 all
devices installed on the same circuit as the router. Compare this total with the rating limit for the
circuit. The maximum ampere ratings are usually printed on the routers near the input power
connectors.
CAUTION
Brocade MLXe routers with DC power sources are intended for installation in restricted access
areas only. A restricted access area is where access can be gained only by service personnel
through the use of a special tool, lock and key, or other means of security, and is controlled by the
authority responsible for the location.
CAUTION
Brocade MLXe routers with AC power sources are intended for installation in restricted access
areas only. A restricted access area is a location where access can be gained only by service
personnel through the use of a special tool, lock and key, or other means of security.
CAUTION
For the DC input circuit to the system of Brocade MLXe-4. Brocade MLXe-8, and Brocade MLXe-16
routers (1800W supply), make sure there is a 60 amp circuit breaker, minimum -48VDC, double
pole, on the input lugs to the power supply. The input wiring for connection to the product should
be copper wire, 6 AWG, marked VW-1, and rated minimum 90  C.
CAUTION
For the DC input circuit to the system of Brocade MLXe-4. Brocade MLXe-8, and Brocade MLXe16
routers (1200W supply), make sure there is a 40 amp circuit breaker, minimum -48VDC, double
pole, on the input lugs to the power supply. The input wiring for connection to the product should
be copper wire, 6 AWG, marked VW-1, and rated minimum 90  C.
CAUTION
For the DC input circuit to the system of a Brocade MLXe-32 router (3000W supply), make sure
there is a 80 amp circuit breaker, minimum -48VDC, double pole, on the input lugs to the power
supply. The input wiring for connection to the product should be copper wire, 2 AWG, marked
VW-1, and rated minimum 90  C.
