The Vertiv VR3157SP is a 48U floor-standing networking rack from the Vertiv VR Rack family, measuring approximately 800 mm wide, 1100 mm deep and 2266 mm high. VR Rack frames are engineered for quick deployment in high-density server rooms and data centres and give roughly 2.5 in. (about 63 mm) more usable depth than comparable 19-inch cabinets, leaving more room behind long servers for power cords and cabling. The 800 mm width creates generous side channels for vertical cable management and patching, which makes this model a strong fit for switching and network aggregation.

Every VR Rack ships with a single 77% perforated locking front door and split 77% perforated locking rear doors - both can be hinged on either side - plus two pairs of split, locking side panels with slam latches for easy removal. A high-density cable entry top cover handles up to about 2,000 Cat 6 cables, and two full-height, depth-adjustable brackets in the zero-U space serve as toolless mounting points for rack PDUs and cable management.

The frame carries 1361 kg (3,000 lb) static and 1134 kg (2,500 lb) dynamic load. Two sets of 19-inch EIA rails are fully depth-adjustable, and accessories such as shelves, blanking panels and cable managers install without tools. The 48U frame maximises rack space per floor tile for dense deployments. Cabinets can be bayed externally on metric spacing or on 24 in. centres.

The SP version is delivered on shock packaging rated for 2,000 lb (907 kg), so the rack can be fully integrated with equipment off-site and shipped to its destination as a ready-to-run system.
