Chapter 2 Connecting and Routing Cables to the HP NetServer LXr 8000 Power Considerations for the HP NetServer LXr 8000 The HP NetServer LXr 8000 can be configured in either of two voltages: 208, or 230/240 VAC. Power supply (UPS) and distribution (PDU) components are available to support these configurations. Power considerations for the HP NetServer LXr 8000 include: ◊ available in 208 VAC model for the U. S. market ◊ available in either 208 VAC or 230/240 VAC models for international markets ◊ Uninterruptible Power Supply (UPS) models rated at 3000 Watts are available in both voltages ◊ for both 208 and 230/240 voltages, two Power Distribution Unit (PDU) models (rated 10 A and 16 A) are available ◊ one, two or three PDUs can be used in each rack enclosure, depending upon requirements for power, current, and number of receptacles ◊ the appropriate power cord for each server is shipped according to local requirements; refer to Table 3-1 for details 208V PDU Rack Power Configurations The 208 VAC PDU power configurations appear as shown below in Table 2-3 and Figure 2-8. Recommended 208 VAC Power Configurations In the United States, if you are using a UPS use PDU model E7671A or E7672A. Attach the IEC 320 C-19 end of the E7801A cord to the PDU and attach the L620 end of the same cord to the NEMA L6-20 receptacle on the UPS. Alternate 208 VAC Power Configurations In the 208 VAC case, without a UPS, make sure your power system has the capacity to support the power and current needs of the components you will power. (See the section titled "Site Preparation: Circuit Breakers.") If power and current capacity are adequate, plug the PDU into a 208 V, L6-20 receptacle. 28
