Bus Bars - HP BL20p - ProLiant - G2 Setup And Installation Manual

Cabling and Powering Up the System

Bus Bars

This section provides first-time installation procedures. If you are installing a bus bar
after initial installation, be sure that the system is powered down and power supplies
are removed.
WARNING: Be sure that all power enclosure and bus bar circuit breakers are
locked in the off position before connecting any power components. Refer to
the "Scalable and Mini Bus Bar Components" section in this chapter.
NOTE: To simplify cabling for multiple server blade enclosures, begin cabling the enclosures
sequentially from bottom to top. The couplers are labeled by bus and by number.
To connect couplers to server blade enclosure:
1. Unfasten the hook-and-latch strap securing the power cable and coupler.
2. Connect the bus A coupler to the DC input connectors for bus A on the server
blade enclosure.
