Vertiv Rpdu Monitored Unit Level EC 30A 120/208V 5.7KW Vertical (20) IEC C13 (4) - VP4N30AH

Vertiv VP4N30AH Monitored Vertical PDU, 30A, 120/208V, 36-Outlet, 0U Rack Mount

Overview

The Vertiv VP4N30AH is a 0U vertical rack power distribution unit built for high-density data center and IT closet deployments where outlet-level monitoring and remote visibility into power consumption matter. Rated at 30A with a NEMA L14-30P input plug, it delivers 5.7kW across 36 outlets — covering mixed C13, C19, and NEMA 5-20R loads in a single vertical chassis that mounts in the rear of a standard rack without consuming a single rack unit. If you're managing cabinet power budgets across many racks, the VP4N30AH gives you per-outlet current and voltage readings without requiring a separate monitoring appliance.

Key Features

• 36 Mixed Outlets (20× IEC C13, 4× IEC C19, plus NEMA 5-20R): Handles the typical server/network mix out of the box — C13 for 1U servers and switches, C19 for high-draw devices like blade chassis PSUs or UPS bypasses, and NEMA 5-20R for equipment with standard North American plugs. You won't need adapters for most mixed-load racks.
• 30A / 5.7kW at 120/208V: The L14-30P input supports both 120V single-phase and 208V split-phase sources, making this unit deployable in NA data centers running either distribution voltage. At 5.7kW rated capacity, it handles a densely loaded 42U rack without running close to the breaker threshold.
• Monitored Unit-Level with LCD Display: The onboard LCD gives local technicians an immediate read on current, voltage, and power draw without logging into the network — useful during initial commissioning or when network access is disrupted. Remote monitoring via SNMP means your DCIM or NMS can poll live power data continuously.
• SNMP v1/v2c/v3 + HTTPS/SSH: All three SNMP versions are supported, so you can integrate with legacy NMS platforms while still enforcing encrypted v3 polling for new deployments. HTTPS and SSH ensure management traffic is encrypted in transit — important for compliance-sensitive environments.
• RADIUS, LDAP, and TACACS+ Authentication: Enterprise authentication protocols mean the VP4N30AH plugs into existing AAA infrastructure rather than maintaining local credentials. TACACS+ in particular is common in network-heavy environments where Cisco ISE or similar is already deployed — one less credentials silo to manage.
• IPv4/IPv6 Dual-Stack Networking: Full dual-stack support means the unit is deployable in modernized DC fabrics running IPv6 alongside legacy IPv4 without any workaround or NAT gymnastics.
• 3-Meter Input Cable: The 3m (approximately 10 ft) whip gives enough reach from the PDU's vertical mount position to the floor PDU or panel distribution point in most standard rack rows — avoids the cable-length shortfall that forces awkward routing in deep racks.
• Syslog, NTP, SMTP Alerting: Native Syslog export feeds directly into SIEM platforms. NTP synchronization keeps timestamps consistent across log sources. SMTP support enables direct email alerting on threshold breaches without requiring an external alerting proxy.
• Modbus TCP: Modbus TCP support is notable for environments with building management systems (BMS) or industrial energy monitoring infrastructure — this PDU can report power data to Schneider EcoStruxure, Siemens, or similar BMS platforms without a protocol gateway.
• USB and Serial Ports: One USB and one serial (RS-232) port provide local management access and firmware update paths that don't depend on network availability — relevant during initial setup or network outage recovery scenarios.

Integration and Compatibility

The VP4N30AH integrates natively with DCIM platforms and NMS tools via SNMP v1/v2c/v3. The Modbus TCP protocol extends compatibility to building automation and energy management systems that don't speak SNMP. For identity management, RADIUS, LDAP, and TACACS+ cover the major enterprise AAA stacks. The 1× RJ-45 Ethernet port is the sole network interface — plan your management VLAN accordingly if you're deploying multiple units across a shared out-of-band management network. The unit operates across a 100–240V input range at 50/60 Hz, meaning it can be deployed in international data center facilities without voltage adjustment.

Frequently Asked Questions

Q: What outlet types does the VP4N30AH provide?

A: The VP4N30AH includes 20× IEC C13 outlets, 4× IEC C19 outlets, and NEMA 5-20R outlets, for a total of 36 AC outlets. This mix covers standard 1U servers and switches (C13), high-draw equipment like blade chassis PSUs (C19), and North American-plug devices (5-20R).

Q: What is the input plug type and maximum current on the VP4N30AH?

A: The VP4N30AH uses a NEMA L14-30P input plug and is rated at 30A maximum current, delivering up to 5.7kW at 120/208V.

Q: Does the VP4N30AH support SNMP v3 and encrypted management?

A: Yes. The VP4N30AH supports SNMP v1, v2c, and v3, along with HTTPS and SSH for encrypted management access. Enterprise authentication via RADIUS, LDAP, and TACACS+ is also supported.

Q: Can the VP4N30AH integrate with building management systems?

A: Yes. The unit supports Modbus TCP, which is the protocol commonly used by building management systems and industrial energy monitoring platforms, enabling direct integration without a protocol gateway.

Q: How is the VP4N30AH mounted in a rack?

A: The VP4N30AH is a vertical 0U PDU, meaning it mounts vertically in the rear of a standard rack without occupying any rack unit space. This preserves all rack units for active equipment.

Q: What local monitoring does the VP4N30AH provide?

A: An onboard LCD display provides local visibility into current, voltage, and power draw without requiring network access. This is useful during commissioning and during network maintenance windows.

Jerry Tildsen

The VP4N30AH stands out in the monitored PDU category primarily because of its protocol depth — SNMP v3, Modbus TCP, RADIUS, LDAP, and TACACS+ on a 30A vertical unit is a spec stack you typically see on higher-tier intelligent PDUs. For data center teams running mixed BMS and IT monitoring infrastructure, that Modbus TCP support alone can eliminate a protocol gateway that would otherwise sit between the PDU and the building energy management system.

Technical Highlights:

• 36-Outlet Mixed Configuration: 20× C13, 4× C19, and NEMA 5-20R in one unit covers the realistic outlet mix of a high-density rack without requiring outlet adapters — C19 slots handle blade chassis and UPS input cords up to 16A per outlet.
• SNMP v1/v2c/v3 + HTTPS/SSH: v3 with HTTPS/SSH means this unit satisfies encrypted management requirements in compliance-driven environments (PCI, HIPAA adjacent) without a separate encryption proxy.
• NEMA L14-30P / 120–240V Input: The L14-30P plug and 100–240V input range make this unit deployable from standard 30A locking circuits in North American facilities running either 120V or 208V distribution — no rewiring, no step-down transformer.

Deployment Considerations:

• The unit has a single RJ-45 Ethernet port — if you're deploying multiple PDUs per rack on a dedicated out-of-band management network, plan your management switch port count and VLAN segmentation before racking. Daisy-chaining is not confirmed from available specs, so each unit needs its own port.
• The 3m input cable works in most standard rack rows, but in deep-row or end-of-row configurations where the panel is mounted more than 10 feet away, verify cable routing before ordering — extensions for L14-30P can introduce voltage drop on long runs at full 30A load.

Best fit for colocation operators, enterprise IT teams, or managed service providers deploying high-density compute racks where DCIM integration and BMS-level energy reporting are requirements, not nice-to-haves. The Modbus TCP and TACACS+ combination in particular makes this the right call for facilities already running industrial energy monitoring or Cisco ISE-based AAA.
