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.
CAUTION
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.
CAUTION
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.
