Vertiv VR Rack

Vertiv rates VR at 3,000 lb static, but its own installer guide says roll it only when empty

Vertiv VR Rack is one of 3 racks and enclosures tracked in the SecondWatt catalogue, each with specifications, lead times and indicative secondary-market pricing.

Cabinet density is what forces the cooling decision. Beyond about 40 kW a rack is no longer air-served, and the enclosure has to accommodate liquid cooling, either as rear-door and direct-to-chip manifolds or as a full immersion tank in place of the cabinet. The catalogue entries closest to that decision are Vertiv Liebert XDU Coolant Distribution Unit and CoolIT Systems DCLC Direct Liquid Cooling.

Vertiv VR Rack specs, static versus dynamic weight ratings, and pricing across 26 SKUs for buyers evaluating new or used 19-inch data center cabinets.

Vertiv markets this cabinet interchangeably as "Vertiv™ Rack" and "VR Rack," and its own current Selection Guide (SL-11367) lists 26 SKUs spanning three U heights (42U, 45U, 48U), two widths (600mm, 800mm), and two depths (1100mm, 1200mm), each offered in standard, shock-packaged ("SP"), and TAA-compliant variants. Every SKU shares one uniform weight rating: 3,000 lb static, 2,250 lb dynamic. "VR3350-003" and "VR3357-013," as printed on at least one distributor's own product pages, are not distinct Vertiv models — they are that distributor's own part-number formatting of the official VR3350 and VR3357 designations. That distinction matters because it is exactly the kind of artifact that creates duplicate catalog rows. VR is not a newer replacement for Vertiv's separate DCE Rack System — both are current products sold today. DCE still carries its pre-Vertiv Emerson Network Power / Liebert lineage, visible on distributor pages titled "Emerson DCE Rack," yet Vertiv's own DCE sell sheet is dated SL-11986 (06/25) and its Selection Guide is SL-11995, both live documents. Distributor listings for VR itself also carry "Liebert" as the stated manufacturer on at least one channel, so a used unit may plausibly show Liebert branding rather than "Vertiv" alone. VR has no OCP Open Rack variant of its own. Vertiv's Open Rack OCP product is a wholly separate frame built to OCP's 21-inch/533mm usable width and 48mm OpenU rather than EIA-310's 44.45mm U, rated 1,600 kg static and 1,400 kg dynamic, and it shares no SKUs with the VR line.

Why it matters

Vertiv rates every VR cabinet 3,000 lb static, but the number that governs a loaded move is 2,250 lb, a 25% cut confirmed identically across four independent sources with no disagreement between them. Vertiv's own installer guide goes further still, recommending that casters move the rack only when empty. Anyone planning to roll a populated cabinet into place needs that guidance and the 2,250 lb figure, not the 3,000 lb headline most marketing copy and reseller listings quote alone.

Who buys it

Enterprise, colocation, and edge data-center operators sourcing 19-inch EIA-310E cabinets for new or expanding IT rows, plus ITAD dealers and brokers pricing decommissioned VR units pulled from retired rows. A buyer needs the exact SKU — height, width, depth, and SP/TAA suffix — before quoting, since Vertiv treats standard, shock-packaged, and TAA-sourced units as genuinely different catalog numbers at the same shared weight rating, not cosmetic variants of one part.

Role in the data center

White-space IT cabinet housing rack-mount servers, network switches, and PDUs behind 77%-perforated front and rear doors, in enterprise server rooms, colocation suites, and edge sites depending on U height and width/depth configuration.

Key specifications

Technical summary

U height: 42U, 45U, or 48U across 26 current SKUs (VR3100 through VR3357TAA) External width: 600mm or 800mm; external depth: 1100mm or 1200mm Static weight rating: 3,000 lb (1,360 kg), uniform across every VR SKU Dynamic/rolling rating: 2,250 lb (1,022 kg); shock-pallet transit rating (SP models): 2,000 lb (907 kg) Door perforation: 77% open area, front 16-gauge steel, rear 18-gauge split doors Rail: 19-inch EIA, 14-gauge steel folded 5 times, depth-adjustable within 740mm (29.1in) rail spacing Lock: keyed to code 1333; side panels split, 20-gauge, single locking slam latch Cable entry: 4 points, rated to 2,000 Cat6 cables or a 60A PDU run Standards: EIA-310E, UL2416, RoHS, REACH; no seismic or OCP claim on any VR document checked Warranty: 3-year standard, extendable to 5-year with registration

Compatibility and dependencies

Rail depth adjustment is shared across the line at 740mm (29.1in) of usable rail spacing, so accessories rated to that spacing carry across VR's 42U/45U/48U SKUs. The lock cylinder is keyed to a single code, 1333, across the catalog, and a replacement combination lock handle (VRA6023) is available through at least one marketplace reseller at $230.33. Perforated replacement doors are stocked by independent resellers in eight standard sizes, which is what makes reassembling a stripped used unit realistic rather than a full-cabinet write-off.

Pricing and availability

Trend: flat Warranty, new: 3 years standard, extendable to 5 years with registration, confirmed on Vertiv's own VR Rack Selection Guide (SL-11367)..

Lifecycle and maintenance

Vertiv rates VR at a 3-year standard warranty, extendable to 5 years with registration. The enclosure carries no active components beyond doors, hinges, casters, and locks, so service life tracks wear on those parts rather than a defined overhaul interval; Vertiv's installer guide calls for periodic dry-cloth cleaning only, with no scheduled overhaul. A genuine VR-specific parts aftermarket supports reassembling a stripped unit: independent resellers stock VR-branded perforated doors in eight standard sizes and a combination lock handle, VRA6023, priced at $230.33 through one marketplace reseller.

Common failure points

• Caster wheels/bearings — Flat-spotted or seized wheels, uneven roll
• Leveling feet threads — Feet will not extend or retract with the T30 Torx or 14mm wrench
• Side panels or doors missing — Unit listed or received "no sides," "no doors," or "doors only"
• Ground bonding hardware — Star washers missing or factory paint left un-pierced at ground terminals
• Perforated door panels — Bent, dented, or cracked sections of the 77% open-area grid
• Lock cylinders — Cylinder missing, rekeyed, or supplied with no working key
• Weight-rating nameplate — Plate faded, painted over, or inconsistent with the visible model number

Inspection checklist

Weight rating plate — verify legible static (3,000 lb) and dynamic (2,250 lb) figures match the actual model number, not a mismatched or swapped panel. Caster wheels and axles — check for flat spots or bearing play; Vertiv's own installer guide recommends casters move the rack only when empty, so wear here can flag loaded rolling beyond the 2,250 lb rating. Leveling feet — confirm all 4 extend and retract through their full range with a T30 Torx or 14mm wrench, with no stripped threads. Protective-earth ground terminal — verify bonding hardware is torqued to 10 N-m (90 lb-in) and not daisy-chained between adjacent units per NFPA 70 Article 250. Door perforation panels — inspect the rated 77% open-area doors (16-gauge front, 18-gauge rear) for bent or cracked sections that locally choke airflow. Rail depth adjustment — slide both 19-inch rail pairs through their full range within the 740mm (29.1in) usable rail spacing, checking for stripped adjustment screws. Side panels — confirm both split panels are present and the single locking slam latch on each engages fully. Lock cylinders — test that doors and panels turn on the stated key code 1333, and confirm a working key is included. Cable entry grommets — verify all 4 top/bottom entry points are intact and clear; the design is rated for up to 2,000 Cat6 cables or a 60A PDU run. Frame welds and corner posts — inspect near the caster mounting points for cracks or field repair welds, since these bear the full static-plus-dynamic load path. Top panel — confirm it still supports its rated 150 lb static load without visible deflection at the mounting points. Shock-pallet history on SP units — ask whether the unit was ever moved loaded above its 2,000 lb transit rating, since SP packaging governs shipping only, not in-service rolling. Rack unit position labels — verify the color-contrasting RU markings remain legible on both rails for accurate equipment placement. Warranty registration status — confirm whether the unit's 5-year extended term was ever registered, versus defaulting to the 3-year standard term. Paint and finish condition — check doors and side panels for corrosion or heavy scuffing at handling points, since resale value in this category tracks cosmetic condition closely.
