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.
