If onsite installation is selected or required, one Entry-Level/Midrange Site Charge (SAABB-NSSC-000x) must be ordered per site, per visit. The single Entry-Level/Midrange Site Charge will apply to ALL Entry-Level/Midrange products (for which installation has been purchased) being installed during the same onsite visit. If multiple onsite visits are required, order one Entry-Level/Midrange Site Charge per visit. Entry-Level/Midrange Site Charge is not applicable when one or more enterprise systems are being installed at the same location along with entry-level/midrange systems during the same site visit. For example, when installation is ordered for installation at the same site and same visit for two Scalar i3 (entry-level), one Scalar i500 (midrange), and one DXi9100 (enterprise), order one Enterprise Site Charge (SAABB-NSSE-000x) for the four systems.
