Vertiv Rpdu Switched Outlet Level Monitoring EC 30A 120V 2.8KW Horizontal (12) NE - VP7N31A0

Vertiv VP7N31A0 Switched Outlet-Level Monitoring Rack PDU, 30A 120V 2.8kW Horizontal

Overview

The Vertiv VP7N31A0 is a horizontally-mounted, single-phase rack PDU designed for data center and IT closet deployments where per-outlet switching and real-time power monitoring are both required. Drawing from a 30A NEMA L5-30P input at 100–120V and delivering up to 2.8kW across 12 NEMA 5-20R outlets, the VP7N31A0 gives operations teams the ability to remotely reboot locked devices, isolate faulty loads, and track consumption per outlet — all without dispatching a technician to the rack. The onboard LCD provides at-a-glance current, voltage, and power readings; the RJ-45 Ethernet port handles all remote management. For enterprise-managed rack PDUs with this level of control granularity, this is a practical pick for density-sensitive deployments.

Key Features

• Per-Outlet Switching: Each of the 12 NEMA 5-20R outlets can be individually powered on, off, or cycled remotely. This matters in dense racks where a single hung server or network appliance would otherwise require a physical presence to reboot — outlets can be sequenced at startup to avoid inrush-current spikes as well.
• 30A / 120V / 2.8kW Input: The NEMA L5-30P twist-lock input draws up to 30A from a single-phase 100–120V circuit. At 2.8kW rated capacity, this unit comfortably handles a standard half-loaded 1U server rack without pushing the 80% continuous-load threshold. Size the upstream breaker accordingly — a dedicated 30A circuit is required.
• 12 NEMA 5-20R Outlets: The 20A-rated receptacles accept standard 5-15P and 5-20P plugs, which covers virtually all 1U/2U server and network gear with North American power supplies. No adapter pigtails needed for typical rack populations.
• Outlet-Level Current, Voltage, and Power Monitoring: Real-time monitoring at the outlet level — not just aggregate input — means you can track which device is drawing how much, flag anomalies, and generate per-tenant or per-service billing reports. This is the difference between knowing a rack is pulling 18A and knowing which six servers are responsible.
• Enterprise Protocol Stack: The VP7N31A0 supports SNMP v1/v2c/v3, HTTPS, SSH, LDAP, RADIUS, TACACS+, Syslog, SMTP, NTP, Modbus TCP, DHCP, IPv4, and IPv6. That's a complete enterprise management stack — SNMP v3 for encrypted polling, RADIUS/TACACS+ for centralized AAA, Syslog for SIEM integration, and Modbus TCP for BMS/DCIM platforms that prefer that protocol. Most competing units at this price point omit Modbus TCP or TACACS+.
• SSH and HTTPS Encryption: Remote CLI access over SSH and web UI over HTTPS means management traffic is encrypted in transit. Combined with RADIUS or TACACS+ authentication, this satisfies most enterprise security policies without additional appliances in the path.
• LCD Display: The front-panel LCD provides local readout of current, voltage, and power without requiring a laptop or network connection. Useful during initial commissioning or when network management is unavailable.
• 3m (10 ft) Input Cord: The 3-meter input cable provides enough reach from the rack to a floor-mounted PDU or overhead busway tap without needing a cord extension. Measure the drop to your power distribution point before ordering — 3m is generous for most standard 42U racks but may fall short in raised-floor deployments with long horizontal runs.
• Dual IP Stack (IPv4/IPv6): Native IPv6 support means the VP7N31A0 can be managed on modern dual-stack networks without NAT workarounds. Relevant for enterprise and government environments transitioning to IPv6-only management planes.
• USB and Serial Management Ports: One USB port and one serial port supplement the Ethernet management interface. The serial port provides out-of-band access when the network is unreachable — connect a console server or laptop directly for recovery without depending on the production network.
• LED Indicators: Visual status LEDs complement the LCD, giving a quick health check from across the aisle without having to walk up to the unit.
• 0U Horizontal Form Factor: The horizontal rack-mount profile occupies a defined number of rack units (verify with the physical datasheet for exact RU count) and fits standard 19-inch racks. Horizontal orientation simplifies cable management compared to vertical 0U PDUs, at the cost of consuming rack space — factor that into your rack layout.

Integration and Compatibility

The VP7N31A0 integrates with Vertiv's Geist management ecosystem and with third-party DCIM and BMS platforms via SNMP v3 and Modbus TCP. LDAP integration connects the PDU to Active Directory or OpenLDAP for role-based access, eliminating local account sprawl across large PDU fleets. The SMTP alerting capability can push threshold alerts directly to ticketing systems or on-call tools without a separate monitoring proxy. For facilities-side integration, Modbus TCP allows the PDU to report to building management systems alongside HVAC and cooling units. IPv6 dual-stack ensures the unit fits into both legacy and modern management VLANs. Pair with managed network switches that support 802.1X port authentication if your security policy requires device-level network admission control — the PDU's Ethernet port supports standard 802.1X environments. See the PDU selection guide for help matching input plug, amperage, and outlet count to your specific rack load profile.

Frequently Asked Questions

Q: What input plug does the VP7N31A0 use, and what circuit does it require?

A: The VP7N31A0 uses a NEMA L5-30P twist-lock input plug and requires a dedicated single-phase 30A, 100–120V circuit. Per NEC best practice, continuous loads should not exceed 80% of breaker capacity — plan for no more than 24A sustained draw.

Q: What types of devices can plug into the VP7N31A0's outlets?

A: The 12 outlets are NEMA 5-20R receptacles, which accept both standard 5-15P (15A) and 5-20P (20A) plugs. This covers the vast majority of 1U/2U servers, network switches, and storage gear with North American power supplies.

Q: Can I control individual outlets remotely on the VP7N31A0?

A: Yes. The VP7N31A0 is a switched outlet-level PDU, meaning each of the 12 outlets can be independently powered on, off, or cycled via the web UI, SSH CLI, or SNMP. This allows remote reboot of unresponsive devices without dispatching a technician.

Q: What authentication methods does the VP7N31A0 support for remote management?

A: The unit supports RADIUS, TACACS+, and LDAP for centralized authentication and role-based access control, in addition to local accounts. HTTPS and SSH encrypt management sessions in transit.

Q: Does the VP7N31A0 support Modbus TCP for DCIM or BMS integration?

A: Yes. Modbus TCP is listed in the supported protocol stack alongside SNMP v1/v2c/v3, allowing the PDU to report power data to building management systems and DCIM platforms that prefer Modbus over SNMP.

Q: Does the VP7N31A0 support IPv6?

A: Yes. The unit supports both IPv4 and IPv6, making it compatible with dual-stack enterprise networks and government environments that require IPv6-capable management endpoints.

The VP7N31A0 is one of the cleaner choices in the 30A switched-outlet PDU segment specifically because of its protocol depth. Most units at this capacity give you SNMP and HTTPS and call it done — the VP7N31A0 layers in TACACS+, LDAP, Modbus TCP, and dual IPv4/IPv6, which makes a real difference when you're integrating into an enterprise environment with strict AAA policies or a facilities team running a BMS that speaks Modbus. That combination in a horizontal 30A unit is less common than it should be.

Technical Highlights:

• SNMP v3 with TACACS+ / RADIUS: Encrypted SNMP polling plus centralized AAA means you can fold PDU management into the same access-control policy as your switches and routers — no separate local account maintenance across a large fleet.
• Modbus TCP: Direct BMS and DCIM integration without a protocol translator. If your facilities team monitors cooling and power in the same dashboard, the VP7N31A0 participates natively rather than requiring a gateway appliance.
• 12 × NEMA 5-20R switched outlets at 30A / 2.8kW: The outlet count supports a reasonably dense 1U server population; the 20A-rated receptacles handle dual-corded servers with standard C19/C20 adapters or direct 5-20P connections without adapter risk.

Deployment Considerations:

• The 3m input cord is fixed — measure the distance from your rack's PDU mounting position to the nearest 30A L5-30P receptacle or busway tap before committing. Short runs in overhead busway installations have caught teams off guard.
• The unit is rated for 100–120V only. If there's any chance the deployment will migrate to a 208V environment, this unit is not compatible — you'd need a separate 208V PDU family. Confirm the facility voltage before ordering.

For colocation providers managing multi-tenant racks, or enterprise IT teams consolidating PDU management into an existing DCIM or SIEM platform, the VP7N31A0's protocol stack and per-outlet switching capability justify the step up from a basic metered PDU. It's particularly well-suited to racks housing equipment that requires periodic forced reboots — edge compute nodes, remote access servers, or embedded management controllers that can't always recover on their own.
