Completing the hardware location chart

Planning for the physical location includes documenting the rack locations of the enclosures and other devices that are based on the requirements of each device.

The hardware location chart represents the rack into which the enclosures are installed. Each row of the chart represents one Electronic Industries Alliance (EIA) 19-inch wide by 1.75-inch tall rack space or unit, each of which is commonly referred to as 1U of the rack.

Hardware location planning chart

As you design the rack for your system, use Table 1 to record the physical configuration of the control enclosures, expansion enclosures, and other devices in your system.
