2 HP System Racks The HP System Racks conform to the IEC and EIA standards for 19" (482.6 mm) racks. Any HP, or non-HP, equipment that conforms to these standards can be installed in one of these racks. The 1.1 meter and 1.6 meter system racks are measured in EIA (Electronic Industries Association) units. One EIA unit equals 44.45 mm (1.75 inches). The 1.1 meter rack provides 21 EIA units of usable rack height and the 1.6 meter rack provides 32 EIA units of rack space. All racks are 905 mm deep with 851 mm of usable depth. When ordering a stand-alone computer rack, order rack-mount kits for each component that you plan to install in the rack. You may also need to order filler panels for the empty space remaining in the computer rack. The 1.1 meter stand-alone computer rack comes with 3 filler panels and the 1.6 meter stand-alone computer rack comes with 2 filler panels. When ordering a stand-alone computer rack, you have options for 120 V to 240 V power distribution in North America and 230 V in Europe. The 240 V option is recommended in the US for the 1.6 meter computer rack to prevent current overloads. This is based on the common 20 amp limit of most US building codes. Equipment uses half the current at 240 V that it would use at 120 V, so a 240 V Power Distribution Unit (PDU) allows more equipment to be run off a single PDU and off a single wiring circuit in your building. European computer racks all have 230 V power distribution units. Users in Asia Pacific and South America should order the power option appropriate for the power supply in their country. 3

HP System Racks
The HP System Racks conform to the IEC and EIA standards for
19” (482.6 mm) racks. Any HP, or non-HP, equipment that conforms to these
standards can be installed in one of these racks.
The 1.1 meter and 1.6 meter system racks are measured in EIA (Electronic
Industries Association) units. One EIA unit equals 44.45 mm (1.75 inches).
The 1.1 meter rack provides 21 EIA units of usable rack height and the 1.6
meter rack provides 32 EIA units of rack space. All racks are 905 mm deep
with 851 mm of usable depth.
When ordering a stand-alone computer rack, order rack-mount kits for each
component that you plan to install in the rack. You may also need to order
filler panels for the empty space remaining in the computer rack.
The 1.1 meter stand-alone computer rack comes with 3 filler panels and the
1.6 meter stand-alone computer rack comes with 2 filler panels.
When ordering a stand-alone computer rack, you have options for 120 V to
240 V power distribution in North America and 230 V in Europe.
The 240 V option is recommended in the US for the 1.6 meter computer rack
to prevent current overloads. This is based on the common 20 amp limit of
