DRAFT: BROCADE CONFIDENTIAL
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.
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.
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 90ºC.
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
90ºC.
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.
For the NEBS-compliant installation of Brocade MLXe-32, routers with AC and DC systems, use a ground
wire of at least 2 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.
