Chapter 7. Planning worksheets (customer task)
Customers are responsible for completing the system planning worksheets.
The customer then provides the worksheets to the IBM SSR when they install and congure the system.
Completing the hardware location chart
Planning for the physical location of the system hardware includes documenting the rack locations of the
enclosures and other devices. To determine the rack location, review the requirements and specication
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. As you design your rack for your system,
use Table 23 on page 73 to record the physical conguration of the enclosures and other devices in your
system.
