Vertiv VP7N30AJ Switched 3-Phase Vertical PDU with Outlet-Level Monitoring
Overview
The Vertiv VP7N30AJ is a 0U vertical rack PDU built for high-density three-phase deployments where granular power visibility matters at the individual outlet level. Rated at 30A / 17.2kW on a 200–240V / 346–415V WYE input, it delivers 48 C13 outlets in a vertical form factor that mounts inside the rack cabinet without consuming a single rack unit. If your data center, server room, or edge deployment demands per-outlet switching, real-time monitoring of current, power, voltage, and temperature, and a full enterprise protocol stack, this is the unit to evaluate.

Key Features
- 48 C13 Switched Outlets: Every outlet can be individually switched on, off, or power-cycled remotely — a critical capability when you need to reboot a hung server in a remote cage without dispatching a technician. That's a real operational cost reduction at scale.
- 17.2kW / 30A Three-Phase Input: A NEMA L22-30P plug feeds a 200–240V / 346–415V WYE circuit. Three-phase distribution means balanced load across phases and higher usable power per PDU compared to single-phase units at equivalent amperage — fewer PDUs per high-density rack.
- Outlet-Level Monitoring — Current, Power, Voltage, Temperature: You get granular telemetry at each outlet, not just at the PDU input. That means you can track per-server power draw, identify capacity headroom, and respond to anomalies before they become incidents. Temperature monitoring at the unit adds a basic environmental check without separate sensors.
- Dual RJ-45 Ethernet Ports: Two network interfaces support daisy-chaining or redundant network connectivity. Daisy-chaining multiple PDUs through a single IP address simplifies network infrastructure in rows with several units — fewer switch ports consumed, one management endpoint per row.
- Enterprise Protocol Stack: SNMP v1/v2c/v3, HTTPS, SSH, RADIUS, LDAP, TACACS+, Modbus TCP, IPv4/IPv6, Syslog, SMTP, and NTP are all supported. This isn't a stripped-down managed PDU — it integrates cleanly with DCIM platforms, SIEM tools, and multi-vendor monitoring stacks without protocol compromises.
- 0U Vertical Mounting: The vertical form factor installs in the side channel of a standard two-post or four-post rack, preserving all 42U for revenue-generating equipment. The 3-meter cable provides enough reach to position the PDU cleanly without strained cable management.
- USB + Reset Button: The onboard USB port supports local firmware updates or configuration without network access. A dedicated reset button lets you recover from a misconfigured network stack without a factory reset — a small but meaningful operational detail in locked-down cages.
- Daisy Chain Support: Linking multiple VP7N30AJ units through the dual Ethernet ports reduces IP address consumption and simplifies SNMP polling. In a dense row of 10+ PDUs, that consolidation is meaningful for both switch port budgets and monitoring agent overhead.
- LED Indicators + LED Display: Local status is readable at the PDU without logging into the management interface. Useful during physical audits, initial commissioning, and any scenario where network access is unavailable.
Integration & Compatibility
The VP7N30AJ's protocol breadth makes it compatible with most enterprise DCIM and monitoring platforms. SNMP v3 with authentication and encryption is the right choice for security-conscious environments — pair it with your existing NMS or DCIM tool via the three-phase PDU category for full environmental and power management integration. RADIUS, LDAP, and TACACS+ support means user authentication routes through your existing directory infrastructure rather than requiring local account management on each PDU. Modbus TCP extends compatibility to building management systems (BMS) and industrial monitoring platforms. For environments running IPv6-only or dual-stack networks, native IPv6 support means no NAT workarounds. See UPS and battery backup options for upstream power protection that pairs with this PDU, and consider rack enclosures compatible with vertical 0U mounting.
Frequently Asked Questions
Q: What input plug does the VP7N30AJ use, and what circuit is required?
A: The VP7N30AJ uses a NEMA L22-30P plug, which requires a 30A three-phase WYE circuit operating at 200–240V or 346–415V. Confirm your facility's three-phase circuit type before ordering — a single-phase circuit will not work with this PDU.
Q: Does the VP7N30AJ support per-outlet power switching, or only monitoring?
A: It supports both. Each of the 48 C13 outlets can be individually switched on, off, or power-cycled remotely through the network management interface. This is a switched PDU, not a monitored-only unit.
Q: How many PDUs can be daisy-chained together on one IP address?
A: The VP7N30AJ supports daisy chaining via its dual RJ-45 Ethernet ports. Consult the Vertiv firmware documentation for the maximum chain length supported by the current firmware version, as this can vary by release.
Q: What authentication protocols are supported for user access?
A: The VP7N30AJ supports RADIUS, LDAP, and TACACS+ for centralized authentication, in addition to local accounts. SNMP v3 provides authenticated and encrypted SNMP access for monitoring integrations.
Q: What outlet type does this PDU provide?
A: All 48 outlets are IEC 60320 C13 couplers, suitable for standard C14 server and networking equipment power cords. This PDU does not include C19 outlets — verify your equipment's power cord requirements before deploying.
Q: Can this PDU be used in a horizontal rack mount configuration?
A: The VP7N30AJ is designed as a vertical 0U PDU for side-channel installation inside rack cabinets. It is not intended for horizontal rack-unit mounting.
The VP7N30AJ sits in a specific but important category: high-density three-phase PDUs where you need to do more than just distribute power. The 48 C13 switched outlets with per-outlet monitoring of current, power, and voltage is the spec that separates this unit from basic metered PDUs. If you're managing 40+ servers in a dense row and need to track per-device power consumption or remotely reboot a hung node, that granularity is not optional.
Technical Highlights:
- 17.2kW / 30A Three-Phase Input: WYE topology at 200–240V / 346–415V allows this single PDU to feed 48 C13 loads at meaningful capacity — suitable for mixed server and switching equipment rows where single-phase PDUs would require two or three units to cover the same load.
- SNMP v3 + TACACS+ + LDAP: The authentication and monitoring protocol stack is enterprise-complete. You're not bolting on a workaround to get this into a monitored, directory-authenticated environment — it integrates natively with the tooling already running in the data center.
- Dual RJ-45 + Daisy Chain: Chaining multiple VP7N30AJ units reduces network port consumption per row. In a high-density deployment with 6–8 PDUs per row, consolidating to 1–2 switch ports rather than 6–8 is a meaningful infrastructure simplification.
Deployment Considerations:
- The NEMA L22-30P plug requires a dedicated 30A three-phase WYE circuit — confirm your facility's panel and whip configuration before racking this unit. Mismatched plug types are the most common commissioning delay on three-phase PDUs.
- All 48 outlets are C13 only — no C19 outlets are included. If you have high-draw devices (redundant power supplies pulling 16A+) that require C19 connections, this PDU will not accommodate them without adapters, which introduce a failure point.
The VP7N30AJ is best positioned in purpose-built colocation rows or enterprise data center aisles where per-server power accountability, remote outlet switching, and DCIM integration are operational requirements — not in small server closets or edge deployments where a single-phase metered PDU would be over-specified and simpler to manage.
