Grounding the chassis 59Installing 8004DC power supplies with the BIPIf you install the 8010co BIP, the 8010co equipment shelf load and 8004DCpower rating is limited to 732 W for each power supply. Because of thedifference between the 8010co BIP output circuit protection rating of 30 A,and the 8004DC power supply input current rating of 29 A at –48 V DCnominal operating condition, this limitation is required to ensure the productcomplies with the electrical code.The BIP (DS1400001) does not support the 8005DC power supply.Procedure stepsStep Action1 Install the 8010co chassis as described in previous procedures.2 Install the 8004DC power supplies as described in Installing a DCPower Supply in an Ethernet Routing Switch 8000 Series Chassis(NN46205-307; 313070-E)3 Install the BIP as described in Installing the Breaker Interface Panelfor the Ethernet Routing Switch 8010co Chassis (312755-G).—End—Grounding the chassisNortel recommends that you ground the 8010co chassis before you connectpower cables or network cables to the switch.Prerequisites• To attach a ground to one of the chassis grounding studs, you needthe following:— one single-hole cable lug that fits over one of the grounding studs— a nut and a locking washer for the grounding stud— a 6-AWG grounding wire long enough to connect to the ground point— 7/16-in. hex wrench to fasten the hardwareNortel Ethernet Routing Switch 8600Installing and Maintaining the Ethernet Routing Switch 8000 Series ChassisNN46205-303 01.02 Standard4.1 10 January 2008Copyright © 2008, Nortel Networks.
