HP LH4r HP Netserver LH 3000 Rack Cabling Guide - Page 24

Chapter 2 Rack Cabling References NOTE The extension PDU (E7670A) only increases the number of available receptacles. The total current carrying capacity still is limited to 16 amps for the two PDUs, when daisy chained. In addition, the extension PDU is limited to carrying only 10 amps. Placement of PDU To determine where the PDU mounts, eliminate positions directly behind equipment listed in Table 2-3. (PDUs conflict with these units when mounted in the same space). Then decide the most convenient location. The PDU can be mounted vertically using the non-EIA mounting holes on the outer edges of the vertical columns. Or it can be mounted horizontally between the columns. When monitor and UPS units are present, the PDU can be horizontally mounted across the rack opening, behind one of these units. However, PDUs can also be mounted vertically on the opposite side of the rack from the door hinges. Table 2-3. PDU Placement is Not Recommended behind These Units HP Product Name HP NetServer LH 3000r and LC 2000r HP NetServer LXr 8000 and LXr 8500 HP NetServer LH 3r and LH 4r HP FiberChannel 30 HP NetServer Rack Storage/12 or /12FC Can PDU Be Mounted Behind?
