    Remote Earths: To prevent electrical shock, connect all local (individual office) computers and computer support equipment to the same electrical circuit of the building wiring. If you are unsure, check the building wiring to avoid remote earth conditions. Earth Bonding: For safe operation, only connect the equipment to a building supply that is in accordance with current wiring regulations in your country.

  • Page 20: Environmental Conditions

    In areas where strong waves are generated or where a high-frequency device is installed on the same floor as the server, radio frequency can affect the functionality of the system. Magnetic Fields (MF) - Normally, there is no need to worry about the effect of magnetic fields on computer operations.

  • Page 21: Floor Construction

    Floor Construction Aspects of floor construction, such as load capacity and construction materials, must be considered when installing one or more rack systems. Note: The rack supports up to 551.2 lbs. (250 kg). Use Table 2-1 to calculate the load that each rack of your system configuration places on the floor.
  • Page 22 If you do not know the load capacity of your flooring, consult your building manager or an architect. In many instances the equipment is installed directly on the existing floor and interconnecting power cables are protected by cable covers. In other instances, raised floors – that form a double floor – are used. Some advantages of raised floors are: Interconnecting cables can be routed under the raised floor.

  • Page 23: System Rack Placement

    System Rack Placement The system rack comes equipped with a front stabilizer that: steadies the rack when you extend equipment for servicing, and prevents creeping due to vibration. The stabilizer is predrilled to allow you to secure the system rack to the floor. Note: If preparing the area prior to the arrival of the system, review the power cable restrictions given in “Electrical Facilities”...
  • Page 24 Figure 2-2. Distance Between Stabilizer Anchors If the rack is installed on a concrete floor, you can bolt the rack to the floor using 3/8" concrete drop-in anchors and 1½"-16 bolts. If you are installing your rack in an area with a raised floor, you can use concrete drop-in anchors and 3/8"-16 threaded rod with washers and nuts to secure the rack to the concrete beneath the raised floor.

  • Page 25: Air Conditioning

    Air Conditioning A properly sized air conditioning system ensures stable and reliable operation of your servers by performing the following tasks: cooling the system preventing the generation of static charges preventing the formation of corrosion causing condensation within the system. The system rack’s temperature and humidity requirements are listed in Table 2-2.

  • Page 26: Electrical Facilities

    The air conditioner’s capacity must be larger than the sum of the above items. Use Table 2-3 to calculate calorific values – in BTUs. Table 2-3. Calculating Total Calorific Values Component Basic System Unit (typical) Disk Expansion Unit (typical) Monitor 8-Port Concentrator Total Electrical Facilities...

  • Page 27: Grounding Requirements

    For safety reasons, ground connections are necessary for both power distribution systems and air conditioners. If it happens that the ground to the server and the safety ground must be shared, branch it near the grounding electrode. If a building structure such as a steel frame is used as a grounding electrode, use the main structural member closest to the building foundation.

  • Page 30: Cabling Constraints

    When planning your system configuration you must consider the length of the cables that interconnect system components. If a Server without any additional options meets all of your current computing needs, you will only have to concern yourself with connections to your keyboard, mouse, monitor and your LAN.

    Configuration Guidelines When you configure a system, you should check your configuration to ensure compliance with the following guidelines: 1. To improve rack stability when servicing system components, mount heavier items such as servers in the bottom of the rack. If your rack is a stand-alone unit and the rack is more than 75% filled with components, consider installing the optional side stabilizer kit.

  • Page 60: Installing A Power Distribution Unit

    Installing a Power Distribution Unit If you are not using an Uninterruptible Power Source (UPS), AC power is distributed to system components through a Power Distribution Unit (PDU). See Figure 5-9. The PDU comes equipped with a 15-foot power cord and can be installed either in the bottom of the rack, or when rack space is at a premium, directly behind your keyboard tray.

  • Page 61: Installing A Keyboard Tray

    To install your PDU: 1. Place two cage-nuts (Figure 5-9,A) on each rail at the location you have chosen to mount your PDU. 2. Secure the PDU to the rails using the black plastic washers and plated-finish screws (Figure 5-9, C). 3.
