    Always follow these safety precautions to avoid injury and damage to Storage Center equipment. If equipment described in this section is used in a manner not specified by Dell, the protection provided by the equipment could be impaired. For your safety and protection, observe the rules described in the following sections.

  • Page 32: Electrical Safety Precautions

    Follow these guidelines to protect your equipment from ESD: • Dell recommends that you always use a static mat and static strap while working on components in the interior of the chassis. • Observe all conventional ESD precautions when handling plug-in modules and components.

  • Page 36: Connect The Front-End Cabling

    Front-end cabling refers to the connections between the storage system and external devices such as host servers or another Storage Center. Dell recommends connecting the storage system to host servers using the most redundant option available. In addition, make sure that the speed of the HBAs in the storage controller match the speed of the host server.

  • Page 37: Connecting To Host Servers With Fibre Channel Hbas

    When using Fibre Channel for front-end connectivity, zones must be established to ensure that storage is visible to the servers. Use the zoning concepts discussed in this section to plan the front-end connectivity before starting to cable the storage system. Dell recommends creating zones using a single initiator host port and multiple Storage Center ports. WWN Zoning Guidelines When WWN zoning is configured, a device may reside on any port, or change physical ports and still be visible, because the switch is seeking a WWN.
