Chapter 2 Rack Cabling References Guidelines for Powering the LH 6000r in a Rack Four Possible 200/240 VAC Wide Range PDU Configurations Use of four possible 200/240 VAC PDU configurations depends upon the power requirements of the devices in the rack. Table 2-4 shows how to determine how many PDUs are supplied with each rack configuration. In configurations that use a wide-ranging 10-amp PDU, it will always be plugged into a wide ranging 16-amp PDU. Table 2-4. Number, Type, and Ratings of 200/240 VAC PDUs Wide Range 16 Amp 1 1 2 2 Wide Part Numbers Range 10 Amp (Note 3) 0 E7671A (Note 1) 1 E7672A (Note 2) 0 E7671A + E7671A 1 E7671A + E7672A C-19 Receptacles 2 2 4 4 C13 Total Amps Receptacles 6 16 15 16 12 32 21 32 Note 1. The E7671A includes one 16 amp PDU. The cord that attaches it to the power source must be ordered separately, specifying the cord end required. Note 2. The E7672A includes one 16 amp PDU, one 10 amp PDU, and the cord that attaches them together. The cord that attaches the 16 amp PDU to the power source must be ordered separately, specifying the cord end required. Note 3. The 10-amp PDU can be ordered as an accessory using part number E7670A. The cord that connects it to the 16-amp PDU must be ordered separately. Guidelines for PDU Placement Your wide-range PDU configuration is determined using Table 2-4 and by application of the following guidelines: 1. The first configuration in the list in Table 2-4 that meets receptacle count, current requirements, and power requirements is recommended by rack configuration tools and is supplied, unless the purchaser has overridden this choice. 2. The total power drawn by all components in the rack is accumulated by rack configuration tools, and a second UPS is recommended if wattage of the first is exceeded. 3. One 16-amp PDU is supplied for each Uninterruptible Power Supply (UPS) in a rack. (a) When several HP Rack Storage/12 or Rack Storage/12FC units are in the same rack, use of two wide-range 16-amp and one wide-range 10-amp PDU may not provide sufficient receptacles. 23
