The customer, with the advice of the Teradata representative, is responsible for performing the environmental stabilization.

If temperature and humidity changes have been extreme during transit, cabinets and components may develop condensation. Before installing or powering on the system:
  • The on-site installation environment must meet the operational requirements specified in Environmental Requirements.
  • Cabinets and components must be free of condensation.
  1. After moving the cabinets to the installation location, use the guidelines in the following table to determine the appropriate stabilization time.
    Condition Stabilization Period
    • No extreme temperature and humidity changes during transit and between the customer’s receiving area and on-site destination
    • Desiccant is present
    • No condensation is present on the cabinets or components
    None
    • Extreme temperature and humidity changes during transit and between the customer’s receiving area and on-site destination
    • Desiccant is present
    • Condensation is present on the cabinets or components
    4 hours
    • Extreme temperature and humidity changes during transit and between the customer’s receiving area and on-site destination
    • Plastic bag is missing
    • Desiccant is missing
    • Condensation is present on the cabinets or components
    8 hours
  2. After the stabilization period, remove and discard the plastic bags and desiccant.
    Check the inside and top of each cabinet for desiccant.
  3. Before and during installation, periodically inspect the surfaces of the cabinets and components for condensation:
    1. If condensation is present, allow an additional stabilization period of two hours.
    2. Repeat the two-hour period until there are no signs of condensation.
