Vertiv I10058L Metered Upgradeable Vertical Rack PDU
Overview
The Vertiv I10058L is a 20A, 3-phase WYE metered vertical rack power distribution unit designed for high-density data center cabinets where real-time power visibility matters and future monitoring upgrades need to remain an option. Carrying part number MN01D4W0-41ML59-2TL21A0A10-S, this 72-inch unit ships with 41 total receptacles across three outlet types, a front-entry 10-foot power cord terminated in a NEMA L21-20P twistlock plug, and a high-visibility LED display that shows live power consumption without requiring a network connection or software.
The defining characteristic of this unit is its upgradeable PDU architecture: the metered hardware is designed from the outset to accept a hot-swap Interchangeable Monitoring Device (IMD), letting you step up to full monitored functionality — per-outlet switching, network-based SNMP or Modbus control, remote access — without pulling the PDU from the rack or rewiring. That upgrade path is worth pricing into your initial deployment if remote monitoring is even a possibility down the road.
Key Features
- 41 Outlets Across Three Types: 33 locking IEC C13 outlets, 6 locking IEC C19 outlets, and 2 NEMA 5-20R receptacles give you coverage for 1U/2U servers (C13), high-draw gear like UPS bypass and storage arrays (C19), and standard 120V utility loads (5-20R) — all in a single unit. Balancing C13 and C19 counts like this is typical for mixed-server cabinets where a few heavy hitters share rail space with a larger population of 1U nodes.
- U-Lock IEC Receptacles with Color-Coded Circuit ID: The IEC C13 and C19 outlets use Vertiv's U-Lock retention mechanism, which physically locks the cord into the outlet and requires a deliberate push-to-release action. Color coding — orange, green, and blue across three circuits — makes phase identification instant during cabling and troubleshooting, reducing the risk of inadvertently loading one leg while leaving another light.
- 20A 3-Phase WYE at 5.7kW (208V): At 208V WYE, each of the three phases delivers up to 20A, with the full unit rated at 5.7kW input capacity. Deploying at 80% derate (the NEC standard for continuous loads) keeps you safely under 4.6kW per phase — enough for a fully populated mixed-server cabinet in most enterprise configurations.
- Three-Level Power Monitoring via Local Display: The LED display reports aggregate unit-level metrics (kWh, W, VA, power factor), per-phase metrics (kWh, W, VA, PF, volts, amps), and per-circuit/breaker current. Measurements are ANSI C12.1 and IEC 62053-21 compliant at 1% accuracy class for aggregate and phase readings, and independently tested to 2% accuracy at the circuit/breaker level. That granularity lets you catch phase imbalance before it becomes a service event.
- Hot-Swap IMD Upgrade Path: The upgradeable chassis accepts Vertiv's Interchangeable Monitoring Devices without removing the unit from the rack or interrupting power. If a monitoring requirement arrives after initial deployment — a data center audit, a colocation contract clause, or simply a management decision — the upgrade is a field operation, not a rip-and-replace.
- 60°C / 140°F Maximum Operating Temperature: Rated to 60°C, this PDU handles high-density hot-aisle environments and containment configurations without thermal derating. Most enterprise data centers run hot aisles between 27°C and 45°C; the 60°C ceiling provides meaningful headroom even in facilities without precision cooling.
- TAA Compliant, Made in USA, UL Listed: Country of origin is USA. The unit is TAA compliant, Buy American Act COTS compliant, and UL/c-UL Listed to 62368-1 — the current audio/video/IT equipment safety standard. RoHS compliance covers EU RoHS 2 requirements. For federal procurement or any project with Buy American Act obligations, these credentials matter before the PDU ever reaches a rack.
- Heavy Steel Powder-Coat Chassis, Toolless Mount: The 72-inch chassis mounts toollessly with center-to-center spacing options at 61.25 inches and 64.75 inches — covering the two standard full-rack toolless rail spacings. At 16 lbs shipped weight, a two-person install is straightforward; the heavy steel construction handles the physical stress of fully loaded cord pulls without flex.
Integration and Compatibility
The I10058L connects to any vertical PDU-compatible cabinet with standard 0U vertical rail mount spacing. The NEMA L21-20P twistlock plug requires a matching L21-20 receptacle at the power source — confirm your PDU whip or floor PDU output before ordering. The 10-foot cord with bottom-front entry suits most full-height cabinets, routing cleanly to a floor-level or under-raised-floor feed.
For environments requiring rack and cabinet integration planning, the dual-spacing toolless mount (61.25-inch and 64.75-inch) accommodates the two most common full-height cabinet rail configurations without adapters. FCC Part 15 Class A conformance means this PDU is suited to commercial data center environments; it is not rated for residential or light industrial deployments under FCC Class B rules.
The 12/5 wire gauge on the 10-foot power cable is appropriate for the 20A 3-phase load. Do not extend the power cord — route the cabinet to within 10 feet of the power source, or specify a longer-cord variant at order time. Cord length options are available from Vertiv; confirm before purchase if your installation geometry requires more than 3 meters.
Frequently Asked Questions
Q: Is the Vertiv I10058L TAA compliant and Buy American Act eligible?
A: Yes. The I10058L is manufactured in the USA and is documented as TAA compliant and Buy American Act COTS compliant. It also carries UL/c-UL listing under 62368-1 and RoHS compliance.
Q: What is the warranty on the I10058L?
A: Vertiv provides a 5-year limited warranty on the I10058L.
Q: Can I upgrade the I10058L from metered to monitored without replacing the unit?
A: Yes. The upgradeable chassis accepts a hot-swap Interchangeable Monitoring Device (IMD) from Vertiv, allowing a field upgrade to monitored functionality — including network-based remote access — without removing the PDU from the rack or interrupting power to connected equipment.
Q: What plug type does the I10058L use, and what does the power source need to provide?
A: The I10058L uses a NEMA L21-20P 3-phase WYE twistlock plug on a 10-foot / 3-meter power cord. The power source must provide a matching L21-20 receptacle capable of supplying 20A per phase at 208V WYE (5.7kW total).
Q: What monitoring data is available on the local display without a network connection?
A: The scrolling LED display shows three levels of data: aggregate unit totals (kWh, W, VA, power factor); per-phase readings for phases A, B, and C (kWh, W, VA, PF, volts, amps); and per-circuit/breaker current in amps. Aggregate and phase measurements meet ANSI C12.1 and IEC 62053-21 at 1% accuracy; circuit/breaker current is independently verified to 2% accuracy.
Q: What is the maximum operating temperature for the I10058L?
A: The I10058L is rated to a maximum operating temperature of 60°C / 140°F, making it suitable for high-density hot-aisle and containment environments.
The I10058L is the unit I recommend when a project team is fairly certain they'll need monitoring capability within 12-18 months but doesn't want to budget for a full monitored PDU on day one — or when procurement timelines mean the monitoring decision hasn't been finalized. The 20A 3-phase WYE input at 5.7kW covers virtually any fully loaded 42U or 48U mixed-server cabinet, and the hot-swap IMD architecture means that future upgrade is a field swap, not a maintenance window and a purchase order for new hardware.
Technical Highlights:
- Three-Level Local Monitoring: Aggregate, per-phase (A/B/C), and per-circuit/breaker readings on the LED display — all without a network drop. Phase readings hit 1% accuracy class per ANSI C12.1; circuit current is independently tested to 2%. That's enough data to manage phase imbalance and catch overloads during normal operations without any software dependency.
- 41 Outlets, Three Types: 33 U-Lock C13 at 208V for 1U/2U servers, 6 U-Lock C19 at 208V for storage controllers and high-density compute, and 2 NEMA 5-20R at 120V for KVM, console servers, or utility loads. Color-coded circuit IDs (orange, green, blue per phase) cut troubleshooting time when you're standing in a fully cabled cabinet at 2am.
- 60°C Operating Ceiling: In containment deployments where hot-aisle temps routinely push 40–45°C, a 60°C rated PDU gives you real thermal margin instead of theoretical margin. Many competitors rate to 45°C or 50°C — the difference matters in poorly cooled or temporarily degraded cooling situations.
Deployment Considerations:
- Confirm the L21-20P receptacle is available at your power source before specifying this unit — the 3-phase WYE plug is not universally present in all colocation or enterprise power panels. If your facility runs L6-30 or L15-20 feeds, you'll need a different PDU family.
- The power cord is 10 feet / 3 meters and is not field-replaceable or field-extendable. Plan cabinet placement so the feed lands within 10 feet; Vertiv offers longer-cord variants at order time, but that selection must happen before the unit ships.
This PDU fits best in a colocation or enterprise data center cabinet build where the initial contract is metered-only but a monitored upgrade is a realistic next step — healthcare IT, financial services, or any environment where a future audit or compliance review might mandate per-outlet or per-circuit remote visibility. Buying the upgradeable chassis now preserves that option at hardware cost rather than full replacement cost later.
