Installing a NetIron XMR 32000 router

DRAFT: BROCADE CONFIDENTIAL

For the NEBS-compliant installation of a NetIron XMR 4000, 8000, and 16000 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 router) 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, insure 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.
