Step 4. Check the Power Source
This system can be equipped with two power supplies. When two power supplies are installed, the power
source to the system unit should be provided on two separate power circuits. If the power is supplied this
way, when there is an interruption on one circuit, the system will keep running on the other circuit.
Step 5. Are All of the Internal Options Installed?
These instructions are for systems that have internal options (such as adapters, disk drives, or memory
upgrades) already installed.
If you have internal options that are not installed, install them now. Refer to Chapter 3, “Installing Options”,
on page 23, and then return here.
Step 6. Position the System Unit and Display
Position the system unit and display (optional) at or near their installed location.
Observe the following guidelines when you are positioning the system unit:
v
The system unit weighs between 34 kg (75 pounds) and 41 kg (90 pounds). Do not try to lift the system
unit by yourself.
v Displays and ASCII terminals can weigh as much as 35 kg (77 pounds). Use caution when lifting or
moving the display or ASCII terminal.
v Leave enough space around the system unit to safely and easily complete the setup procedures.
v Observe standard ergonomic guidelines while arranging your system unit so that you can work
comfortably and safely. For more information on arranging your workstation, visit the Healthy Computing
Web address at: http://www.pc.ibm.com/us/healthycomputing.
v Be sure to maintain at least 51 mm (2 inches) of space on the sides of the system unit and 152 mm (6
inches) at the rear of the system unit to allow the system unit to cool properly. The front of the system
requires a minimum of 76 mm (3 inches) of space. Blocking the air vents can cause overheating, which
might result in a malfunction or permanent damage to the system unit.
v
Place the system unit in a location where it can safely and easily reach any necessary power outlets
and network connections.
v Place the display or ASCII terminal in a stable and sturdy location.
