Pdu

47U rack

Mounting the PDUs in the 1U configuration requires an additional 3U of vertical space in the rack. Three PDUs must be mounted facing the front of the rack and three PDUs must be mounted facing the back of the rack (Figure 12). This provides 42U of vertical space for the servers and power enclosures and 3U additional space for the PDU mounting. This configuration must be assembled onsite, as it is not available through Factory Express.

800-mm-wide 42U rack

The 800-mm-wide rack ships standard with vertical blanking panels that block air recirculation back to the front of the rack. Each side of the rack provides 100mm (approximately 4 inches) of space on either side of the rack for access to the 0U space. Access to the PDUs from the front of the rack can be gained by removing the three screws that secure the vertical blanking panels. This configuration must be assembled onsite, as it is not available through Factory Express.
