4 Installing a Brocade NetIron XMR 8000 router

You can supply DC power to your router using a DC-to-DC power supply. DC power must be supplied at 48 V and 40A for 1200W power supplies and 48 V and 60A for 1800W power supplies. The 1200 W DC-to-DC supply provides the DC power to the router at 12 V and 100 A. The 1800W DC-to-DC supply provides the DC power to the router at 12 V and 150 A.

CAUTION

For the NEBS-compliant installation of a Brocade NetIron XMR 4000, 8000, and 16000 routers with AC and DC system 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.
