Installing a Brocade MLX-32 router
DRAFT: BROCADE CONFIDENTIAL
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.
To ensure adequate bonding when attaching the ground lug, a minimum of 20 PSI of torque is required to
be applied to the mounting hardware used to attach the ground lug.
