Vertiv Rpdu Monitored Outlet Level EC 20A 120/208V WYE 5.7KW Vertical (24) Lockin - VP6N20A0

Vertiv VP6N20A0 Monitored Outlet-Level Vertical PDU — 20A, 3-Phase, 24-Outlet

Overview

The Vertiv VP6N20A0 is a 0U vertical rack PDU engineered for high-density data center and server room deployments where outlet-level monitoring matters. Running on a three-phase 100–120/200–240V WYE input with a NEMA L21-20P plug, it delivers up to 5.7kW across 24 C13 lock-in outlets — giving rack managers per-outlet current, voltage, power, and temperature visibility without relying on branch-level estimates. If you're managing a dense compute row or mixed-load rack environment, the VP6N20A0 gives you the granularity to catch runaway loads before they trip a breaker.

The vertical, zero-rack-unit mounting profile keeps all 1U and 2U compute slots available — the PDU mounts to the side rails or the rear of the rack without consuming any horizontal shelf space. The black aluminum chassis and LED status indicators make state checks fast from the aisle without logging into a management console.

Key Features

• Outlet-Level Monitoring (Current, Voltage, Power, Temperature): Unlike branch-monitored PDUs that give you one reading per 8-outlet group, the VP6N20A0 tracks each of its 24 outlets individually. That means you can pinpoint exactly which server in a fully populated rack is drawing abnormally — essential for accurate chargeback reporting and capacity planning in multi-tenant environments.
• 24 x C13 Lock-In Outlets: The lock-in C13 retention mechanism prevents accidental cable pull — a real operational risk in high-density racks during maintenance windows. With 24 outlets on a single 0U unit, you can service a fully loaded 42U rack without a secondary PDU on many configurations.
• Three-Phase Input, NEMA L21-20P Plug: The three-phase WYE input distributes load across all three legs, reducing the risk of phase imbalance in mixed-load racks. The L21-20P twist-lock plug pairs with standard three-phase 20A branch circuits — no special panel work required if your facility already runs three-phase distribution.
• Dual Ethernet (RJ-45) Ports with Daisy Chain Support: Two RJ-45 management ports support daisy-chaining multiple PDUs under a single IP address, reducing the number of DHCP leases or static IPs needed across a multi-PDU row. That's a meaningful operational simplification in large deployments where IP address management overhead adds up.
• SNMP v1/v2c/v3 with Full Protocol Stack: The supported protocol list — DHCP, HTTP, HTTPS, LDAP, NTP, RADIUS, RSTP, SSH, SMTP, SNMP (all three versions), Syslog, TACACS+, Modbus TCP, IPv4/IPv6 — covers virtually every enterprise integration pattern. RADIUS and TACACS+ support means PDU access control can be folded into your existing AAA infrastructure rather than managed as a separate credential silo.
• Modbus TCP: Modbus TCP support is the integration path for building management systems (BMS) and DCIM platforms. If your facility runs Schneider EcoStruxure, Vertiv Trellis, or a third-party DCIM that speaks Modbus, the VP6N20A0 surfaces outlet-level telemetry directly into that dashboard without a separate polling agent.
• LED Display with Reset Button: The onboard LED indicators and hardware reset button support local triage without needing a laptop or console cable. In a lights-out data center environment, fast physical state confirmation during an incident matters — aisle-visible LED status reduces mean-time-to-identify.
• 3-Meter Power Cord: The 3m (approximately 10 ft) cord length accommodates standard rack-to-floor PDU routing without extension cords, reaching most overhead or underfloor distribution panels in a typical hot-aisle/cold-aisle row layout.
• USB Port: The single USB port supports firmware updates and local configuration loading without requiring network connectivity — useful during initial commissioning or after a network misconfiguration that locks out remote management.

Integration and Compatibility

The VP6N20A0 integrates with DCIM and BMS platforms via rack PDU standard protocols. SNMP v3 delivers encrypted, authenticated polling to any NMS that supports trap reception — Nagios, PRTG, SolarWinds, and Vertiv's own Trellis platform all qualify. The Modbus TCP interface provides native integration with building automation layers. LDAP and RADIUS/TACACS+ authentication means PDU user management can be delegated to Active Directory or a RADIUS server, enforcing role-based access without local account sprawl.

Review the full Vertiv power distribution line for companion units including higher-amperage variants, switched PDU options, and metered-only alternatives where outlet-level granularity isn't required. For rack infrastructure planning, pair this unit with compatible server racks and enclosures that support 0U vertical PDU mounting rails. If your deployment requires remote outlet switching in addition to monitoring, evaluate a switched variant in the same Vertiv family before finalizing your PDU specification — the VP6N20A0 provides monitoring but not remote outlet on/off control.

Frequently Asked Questions

Q: What input plug does the VP6N20A0 use, and what circuit does it require?

A: The VP6N20A0 uses a NEMA L21-20P twist-lock plug. It requires a three-phase 20A WYE circuit at 100–120V or 200–240V. Verify your facility's panel has an available three-phase 20A branch circuit before ordering.

Q: Can the VP6N20A0 control (switch on/off) individual outlets remotely?

A: No. The VP6N20A0 is a monitored PDU, not a switched PDU. It provides outlet-level monitoring of current, voltage, power, and temperature but does not offer remote outlet switching. If you need remote power cycling capability, evaluate a switched PDU variant in the Vertiv lineup.

Q: How many PDUs can be daisy-chained together using the dual RJ-45 ports?

A: The VP6N20A0 supports daisy chaining via its two Ethernet ports, allowing multiple PDUs to share a single network connection. Consult Vertiv's daisy chain specifications for the maximum number of units supported per chain on this model.

Q: What rack space does the VP6N20A0 consume?

A: Zero rack units (0U). The VP6N20A0 mounts vertically in the rack — typically to the side rails or rear of the enclosure — leaving all horizontal 1U and 2U slots available for compute and networking equipment.

Q: Which management protocols does the VP6N20A0 support for DCIM or NMS integration?

A: The VP6N20A0 supports SNMP v1/v2c/v3, Modbus TCP, HTTP, HTTPS, SSH, SMTP, Syslog, DHCP, NTP, LDAP, RADIUS, TACACS+, RSTP, and both IPv4 and IPv6. This covers integration with most enterprise NMS platforms, DCIM tools, and building management systems.

Q: What outlet type is used on the VP6N20A0?

A: All 24 outlets are IEC C13 with a lock-in retention mechanism, which prevents accidental cord disconnection during maintenance. Standard IEC C14 server power cables connect directly without adapters.

The VP6N20A0 sits in a specific but important segment of the PDU market: three-phase monitored units with outlet-level granularity. Most facilities deploying mixed compute loads — a blend of 1U servers, GPU nodes, and storage — eventually discover that branch-level metering leaves too much ambiguity when a phase starts trending toward its limit. The 24 C13 lock-in outlets on this Vertiv unit, paired with per-outlet current and power telemetry, let you map load distribution across a rack before you have a problem, not after.

Technical Highlights:

• Dual Ethernet with Daisy Chain: Two RJ-45 ports allow IP consolidation across multiple PDUs in a row — in a 10-rack deployment with two PDUs per rack, that could reduce management IPs from 20 to as few as two or three, depending on chain depth.
• SNMP v3 + TACACS+/RADIUS: Encrypted SNMP polling and AAA-server authentication integration means the VP6N20A0 fits cleanly into enterprise security policy — no plaintext credentials, no local-only account management.
• Modbus TCP: Modbus TCP is the interface your BMS or DCIM platform most likely already speaks. This is what makes outlet-level telemetry available to facility-layer dashboards without custom middleware.

Deployment Considerations:

• The NEMA L21-20P plug is not a common residential or light-commercial connector — confirm your branch circuit panel has three-phase 20A capacity and the correct receptacle before the unit ships. Retrofitting a panel after delivery adds lead time.
• The VP6N20A0 is monitored-only. If any rack in your deployment needs remote outlet reboot capability — for hung network gear or unresponsive servers — you'll need a switched PDU alongside or instead. Plan the PDU mix before finalizing your rack BOM.

This unit is a strong fit for high-density colocation or enterprise compute rows where accurate chargeback reporting, phase-load balancing, and DCIM integration are operational requirements — not for edge closets or light-load environments where a basic metered PDU covers the need at lower cost.
