Checking final preparations

Before you begin

DANGER
HEAVY EQUIPMENT: PERSONAL INJURY OR EQUIPMENT DAMAGE MAY RESULT IF MISHANDLED (D006)

Procedure

  1. Verify that the customer has two ac power sources for each rack being installed.
  2. Verify the customer wall circuit breaker. The customer wall circuit breaker rating that protects each line cord depends on the voltage range as follows:
    • Single-phase (200 - 240 V) require wall circuit breakers that have a rating of 60 to 63 A.
    • Three-phase low-voltage (200 - 240 V) installations require wall circuit breakers that have a rating of 50 to 60 A.
    • Three-phase high-voltage (380 - 415 V) installations require wall circuit breakers that have a rating of 30 to 35 A.
  3. If the storage facility will be installed on a raised floor:
    1. The maximum rack weight exceeds 2500 pounds (1134 kilograms). Have the customer verify that their floor has adequate support.
      Note: For details on the rack weights, refer to the IBM DS8000 Introduction and Planning Guide for your model.
    2. To correctly cool a rack, place two floor tiles with air flow holes directly in the front of each rack.
    3. If the rack does not have features for overhead cable management of power or host cables, or both, place the appropriate floor cutouts under the rear tailgate.
    4. If the rack does have features for overhead cable management, floor cutouts are not required in the following cases.
    • Rack-1, Rack -2:
      • Rack has feature 1400 (top exit bracket for fibre cable), AND
      • Customer wants line cords routed through the top exit
    • Rack-3, Rack-4, or Rack-5:
      • Rack has feature 1400 (top exit bracket for fibre cable) (even though no fibre cables exit Rack 3, Rack 4, or Rack 5), AND
      • Customer wants line cords routed through the top exit.
  4. If the storage facility will not be installed on a raised floor, ensure the customer will provide adequate air flow and temperature around the storage facility.
    Notes:
    • For information about the temperature requirements of the operating environment, see the IBM DS8000 Introduction and Planning Guide for your model. The PDF is also available on the IBM® DS8000® series Service Documents CDROM.
    • The rack cooling airflow enters through the front cover and exits through the rear cover. The bottom of the DS8000 is sealed.
  5. Verify that the customer has ordered, supplied, and routed the following cables to the storage facility being installed.
    Note: Routing of the customer cables must not be billed against the installation. If the customer wants the service representative to route the cables, that activity must be coded or billed separately.
    1. Fibre-Channel host cables from the host to the storage facility host adapters.
    2. An Ethernet LAN signal cable. This cable is required to connect the management console to the customer LAN. A second cable is needed if two management consoles will be connected to the customer LAN.
