    Site and equipment preparation

    The following items must be available at the site to install the storage system:

    • Tools: Slotted or Phillips screwdriver, ESD protection kit, and a mechanical lift (optional).
      Note:   A Slotted or Phillips screwdriver with a six inch or longer magnetic head is recommended for the 12-drive disk processor enclosure.
    • Management console: A Windows-based computer to run the initialization, maintenance, and management tools with:
      • At least 100 MB of free space
      • Connection on same LAN subnet as your storage system (recommended)
      • Web browser (Internet Explorer, Mozilla Firefox, Google Chrome)
        Note:  Refer to the Unity Support Matrix on the support website for compatibility and interoperability information related to the Web browsers.
    • Space: Cabinet vertical space of 2U (3.5 inches, 8.9 cm) for the disk processor enclosure (DPE, 25-drive or 12-drive) and, if applicable, cabinet vertical space of 2U for each optional 25-drive disk-array enclosure (DAE) or 3U (5.75 inches, 14.6 cm) for each optional 15-drive DAE.
    • Network connections:
      • Two 1-gigabit Ethernet management connections
      • Four CNA ports (two per SP) that can be set, if applicable, either at manufacturing time or, if not, during installation or later to:
        • 2 x 10GbE or 1GbE ports, or

        • The default gateway address of the LAN to which the system is connected
        • Passwords for system users admin and service
      • If you are setting up the system on a network with DHCP servers, DNS servers, and Dynamic DNS services, you need:
        • System serial number
        • Domain information

    Hardware acclimation times

    Systems and components must acclimate to the operating environment before applying power. This requires the unpackaged system or component to reside in the operating environment for up to 16 hours in order to thermally stabilize and prevent condensation.

    Table 1 helps you determine the precise amount of stabilization time required.

    Table 1. Hardware acclimation times (systems and components)
    If the last 24 hours of the TRANSIT/STORAGE environment was this:
    …and the OPERATING environment is this:
    …then let the system or component acclimate in the new environment this many hours:
    Nominal 68-72°F (20-22°C)
    Nominal 40-55% RH
    Nominal 68-72°F (20-22°C) 40-55% RH
    0-1 hour
    Cold <68°F (20°C)
    Dry <30% RH
    <86°F (30°C)
    4 hours
    Cold <68°F (20°C)
    Damp ≥30% RH
    <86°F (30°C)
    4 hours
    Hot >72°F (22°C)
    Dry <30% RH
    <86°F (30°C)
    4 hours
    Hot >72°F (22°C)
    Humid 30-45% RH
    <86°F (30°C)
    4 hours
    Humid 45-60% RH
    <86°F (30°C)
    8 hours
    Humid ≥60% RH
    <86°F (30°C)
    16 hours
    <86°F (30°C)
    16 hours
    • If there are signs of condensation after the recommended acclimation time has passed, allow an additional eight (8) hours to stabilize.
    • Systems and components must not experience changes in temperature and humidity that are likely to cause condensation to form on or in that system or component. Do not exceed the shipping and storage temperature gradient of 45°F/hr (25°C/hr).
    • Do NOT apply power to the system for at least the number of hours specified in Table 1. If the last 24 hours of the transit/storage environment is unknown, then you must allow the system or component 16 hours to stabilize in the new environment.

    Avoiding electrostatic discharge (ESD) damage

    When replacing or installing hardware units, you can inadvertently damage the sensitive electronic circuits in the equipment by simply touching them.

    Electrostatic charge that has accumulated on your body discharges through the circuits. If the air in the work area is very dry, run a humidifier in the work area to help decrease the risk of ESD damage.

    Follow these procedures to prevent equipment damage:

    • Provide enough room to work on the equipment.
    • Clear the work site of any unnecessary materials or materials that naturally build up electrostatic charge, such as foam packaging, foam cups, cellophane wrappers, and similar items.
    • Do not remove replacement or upgrade units from their antistatic packaging until you are ready to install them.
    • Before you begin service, gather together the ESD kit and all other materials you will need.
    • Once servicing begins, avoid moving away from the work site; otherwise, you may build up an electrostatic charge.
    • Use ESD anti-static gloves or an ESD wristband (with strap).

      If using an ESD wristband with a strap:

      • Attach the clip of the ESD wristband to the ESD bracket or bare metal on a cabinet/rack or enclosure.
      • Wrap the ESD wristband around your wrist with the metal button against your skin.
      • If a tester is available, test the wristband.
    • If an emergency arises and the ESD kit is not available, follow the procedures in Emergency Procedures (without an ESD kit).

    Emergency procedures (without an ESD kit)

    In an emergency when an ESD kit is not available, use the following precautions to reduce the possibility of an electrostatic discharge by ensuring that your body and the subassembly are at the same electrostatic potential.

    NOTICE  These precautions are not a substitute for the use of an ESD kit. Follow them only in the event of an emergency.
    • Before touching any unit, touch a bare (unpainted) metal surface of the cabinet/rack or enclosure.
    • Before removing any unit from its antistatic bag, place one hand firmly on a bare metal surface of the cabinet/rack or enclosure, and at the same time, pick up the unit while it is still sealed in the antistatic bag. Once you have done this, do not move around the room or touch other furnishings, personnel, or surfaces until you have installed the unit.
    • When you remove a unit from the antistatic bag, avoid touching any electronic components and circuits on it.
    • If you must move around the room or touch other surfaces before installing a unit, first place the unit back in the antistatic bag. When you are ready again to install the unit, repeat these procedures.
