Third party racks with vertical PDUs — RPQ RequiredEach system bay is powered by two redundant power distribution units (PDUs), onePDU for each power zone. Rather than use the standard EMC horizontal PDU, thecustomer can use vertical PDUs via RPQ. The general requirements for third partyracks with rear-facing or inward-facing PDUs are listed below.l Requirements for third party racks with vertical PDUs (inward-facing) on page102l Requirements for third party racks with vertical PDUs (rear-facing) on page 100General requirements for vertical PDUs within third party racksIn addition to meeting standard VMAX array power requirements, vertical PDUs shouldabide by the following:l Both PDUs support AC-line input connectivity and provide outlets for everycomponent in the bay.l The PDU must be available in the wiring configuration that matches the customerpower supply.Options include:n Single-phasen Three-phase Deltan Three-phase Wyel Each PDU should meet the following requirements:n At a minimum, a total of 24 power outlets must be provided.The outlets are divided into six banks with each bank consisting of four IEC60320 C13 individual AC outlets.n Each bank of outlets is connected to individual branch circuits that areprotected by a single two pole 20 Amp circuit breaker.n The PDU capacity should exceed the power requirements shown in the PowerCalculator for the specific max configuration.n Single PDU mounted per side per Figure 32 on page 100 and Figure 33 on page102.If the customer requires power to be supplied from overhead, EMC recommends oneof the following:l Option 1: Replace the rear top cover of the bay with the ceiling routing top cover,described in Overhead routing kit on page 106, which allows the power cablesinside the machine to be routed out through the top.l Option 2: "Drop" the power cables down the hinge side, to the bottom, and routethem inside the machine.The cables should be dressed to allow all doors to open freely, minimize cablecongestion, and provide access to components within the system.Third Party Racking Option for VMAX 450F, VMAX 850F and VMAX 950FThird party racks with vertical PDUs — RPQ Required 99
