CAUTION
Ensure 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 all
devices installed on the same circuit as the device. Compare this total with the rating limit for the
circuit. The maximum ampere ratings are usually printed on the devices near the input power
connectors.
CAUTION
Brocade MLX 4-, 8-, 16-, and 32-slot devices 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
All devices 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 MLX-4, MLX-8 and MLX-16 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, 8
AWG, marked VW-1, and rated minimum 90
C.
CAUTION
For the DC input circuit to the system of a Brocade MLX-32 router (2400W supply), make sure
there is a 75 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, 4 AWG, marked
VW-1, and rated minimum 90
C.
CAUTION
For the NEBS-compliant installation of Brocade MLXe-4, Brocade MLXe--8, and Brocade MLXe-16
routers with AC and DC systems, use a ground wire of at least 6 American Wire Gauge (AWG). The
ground 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 be
crimped 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 has
been cleaned and antioxidant is applied to the bare wire.
