If your order for one or more S Series Nodes includes a rack, a Hitachi Universal V3 Rack is shipped to your site with a limited number of enclosures already installed in the rack:
- For a single S11 or S31 Node, one base enclosure and no more than two expansion enclosures are installed before the rack is shipped. Regardless of the number of S11 or S31 Nodes ordered, the maximum number of enclosures installed before the rack is shipped is three.
- For a single S32 Node, one base enclosure, one expansion enclosure, and no more than two additional expansion enclosures are installed before the rack is shipped
- For two S32 Nodes, two base enclosures, two expansion enclosures, and no more than one additional expansion enclosure are installed.
- For three S32 Nodes, three base enclosures and three expansion enclosures are installed.
If the total number of enclosures for the S Series Nodes included in the order exceeds the numbers cited above, each additional enclosure is packaged and shipped separately from the rack. These additional enclosures must be racked at your site.
If your order includes PDUs in addition to a rack, the PDUs are also installed in the rack before the rack is shipped.
If your order doesn't include a rack, you need to supply a Universal V3 Rack, a Universal V2B Rack, a Universal V2 Rack, or another rack that meets the rack requirements for one or more S Series Nodes. In this case, all the enclosures for the S Series Nodes included in the order must be racked at your site.
To accommodate the depth of the S Series Node enclosures, each rack included in your order is modified before any enclosures are mounted in that rack. The modifications include repositioning the front vertical mounting rails in the rack.
Customer-supplied Hitachi Universal Racks must be modified on site if they cannot already accommodate the depth of the S Series Node enclosures. Other customer-supplied racks may also need to be modified on site.
If an S Series Node includes one or more expansion enclosures, the base and expansion enclosures must be mounted in the same rack. The expansion enclosures must be mounted above the base enclosure. With an S11 or S31 Node, to allow for cable management, exactly one rack unit must be left empty between the base enclosure and the lowest expansion enclosure.
Multiple S Series Nodes can be installed in the same rack. However, to allow for future growth of an S31 or S32 Node, you can choose to install those models in their own racks.
S Series Nodes can be mounted in the same rack as components of other products, as long as the rack has enough available space, weight capacity, and power capacity to accommodate the S Series Node enclosures and the other mounted components. In this case, the S Series Node enclosures must be mounted at the bottom of the rack, with all components of other products mounted above them.
A customer-supplied Hitachi Universal Rack may already contain components of products other than S Series Nodes. Before any S Series Node enclosures can be mounted in the rack, those other components must be temporarily removed from the rack while the front vertical mounting rails in the rack are repositioned. Existing components must also be temporarily removed from other customer-supplied racks that require similar modification.
