Vertiv VP4N30A0 Monitored Vertical PDU — 30A, 208V, 36-Outlet, 0U
Overview
The Vertiv VP4N30A0 is a single-phase, vertical 0U rack power distribution unit rated for 30A at 200–240V (4.9kW) — purpose-built for dense data center and IT closet deployments where you need real-time visibility into power draw at the unit level without consuming precious rack space. Mounting vertically in the rear channel of a standard rack, it delivers 36 locking IEC outlets — a mix of C13 and C19 — fed by a NEMA L6-30P plug on a 3-meter cord. The LED display and onboard monitoring engine track current, voltage, and power simultaneously, surfacing that data over your network via SNMP v3, HTTPS, or Modbus TCP.
For IT architects sizing UPS capacity or facilities managers enforcing per-rack power budgets, real-time monitoring at the PDU level closes the loop between what the UPS says and what equipment is actually drawing — before a breaker trips rather than after.
Key Features
- Vertical 0U Form Factor: Mounts in the rear vertical channel of a standard two-post or four-post rack, consuming zero rack units. This matters in fully-loaded 42U racks where every U is committed — you gain branch-circuit monitoring without sacrificing server or switch space.
- 30A / 208V Single-Phase Input (NEMA L6-30P): Sized to ride a single 30A branch circuit at 208V, delivering up to 4.9kW of usable power. The L6-30P plug mates natively to most modern PDU whips in purpose-built data centers; if your facility runs L6-30R receptacles, this lands without adapters.
- 36 Locking IEC Outlets — C13 and C19 Mix: The locking retention mechanism on each outlet prevents accidental disconnection from cable sag or rack vibration — relevant in high-density environments where dozens of power cords share a tight vertical run. C19 outlets handle high-draw servers and storage arrays; C13 covers networking gear and lighter compute.
- Unit-Level Monitoring — Current, Voltage, and Power: Real-time measurement of all three electrical parameters at the PDU unit level lets you spot overloads before they trip the upstream breaker. Catching a rack creeping from 18A to 26A over a weekend gives ops teams time to rebalance loads rather than respond to an outage.
- LED Display: Local readings without requiring a network hop or laptop — useful during physical installs and rack audits when you need to confirm load before plugging in the next device.
- Broad Protocol Support — SNMP v3, HTTPS, Modbus TCP, and More: The VP4N30A0 speaks SNMP v1/v2c/v3 (for NMS integration with Nagios, PRTG, SolarWinds, or similar), HTTPS for secure browser-based management, Modbus TCP for BMS/DCIM integration, plus LDAP, RADIUS, and TACACS+ for enterprise AAA. IPv4 and IPv6 are both supported, so it fits both legacy and modernized network addressing schemes without a conversion layer.
- SSH, Syslog, and SMTP Alerting: SSH for secure CLI access, Syslog for forwarding events to your SIEM or log aggregator, and SMTP for email-based threshold alerts. These aren't nice-to-haves in a compliant data center — they're audit requirements.
- 1x RJ-45 Ethernet, 1x USB, 1x Serial Port: The Ethernet port handles all network-based monitoring and management. The USB and serial ports provide out-of-band management paths and firmware update options — useful when you need to recover a misconfigured unit without touching the network interface.
- 3-Meter Input Cable: Long enough to route cleanly from the rear vertical position to overhead cable trays or under-floor whips in most standard rack layouts, reducing the need for extension whips that add failure points.
- 50/60 Hz Input Frequency Compatibility: Operates on both US (60 Hz) and international (50 Hz) power infrastructure, making the VP4N30A0 a viable choice for globally distributed deployments where rack standardization across regions matters.
Integration and Compatibility
The VP4N30A0's protocol stack is built for integration into existing data center management stacks. SNMP v3 with authentication and privacy means it will slot into enterprise NMS platforms without requiring a separate management VLAN exception for unencrypted v1/v2c traffic. Modbus TCP opens the door to DCIM and BMS platforms that aggregate power data across the facility — useful when facilities operations and IT operations share a single management pane. LDAP, RADIUS, and TACACS+ support means you can bind PDU access to your existing directory infrastructure rather than managing local credentials per device.
For teams running power distribution and UPS infrastructure, pairing this PDU with upstream UPS capacity monitoring closes the loop on rack-level power accounting. Review the Vertiv product line for compatible UPS and power conditioning equipment designed around the same management ecosystem. If you are specifying rack infrastructure from scratch, consult a rack enclosures and accessories category for compatible vertical cable management panels that co-mount with 0U vertical PDUs.
Frequently Asked Questions
Q: What plug type does the VP4N30A0 use, and what receptacle does it require at the rack?
A: The VP4N30A0 uses a NEMA L6-30P twist-lock plug on a 3-meter input cord. It requires a NEMA L6-30R receptacle at the branch circuit — standard on most purpose-built data center PDU whips and some floor-mounted power strips. Verify your facility's branch circuit receptacle type before ordering.
Q: How many outlets does the VP4N30A0 provide, and what types?
A: The VP4N30A0 provides 36 total IEC outlets — a combination of locking C13 and C19 receptacles. C19 outlets support higher-draw equipment; C13 serves standard 1U servers, switches, and networking gear. All outlets use a locking retention mechanism to prevent accidental disconnection.
Q: Does the VP4N30A0 support SNMP v3 for secure NMS integration?
A: Yes. The VP4N30A0 supports SNMP v1, v2c, and v3. SNMP v3 includes authentication and privacy options, making it suitable for enterprise environments with NMS security policies that prohibit unencrypted v1/v2c polling.
Q: What does the VP4N30A0 actually monitor — is it per-outlet or at the unit level?
A: The VP4N30A0 provides unit-level monitoring of current, voltage, and power. This gives you visibility into the total load on the PDU and upstream branch circuit. Per-outlet switching or per-outlet metering is not listed in the specification for this model — if per-outlet granularity is required, evaluate a switched or outlet-metered variant in the Vertiv Geist PDU family.
Q: Can the VP4N30A0 integrate with enterprise authentication systems like LDAP or RADIUS?
A: Yes. The VP4N30A0 supports LDAP, RADIUS, and TACACS+ for authentication, allowing you to bind PDU management access to your existing directory or AAA infrastructure rather than managing standalone local credentials on each unit.
Q: Does the VP4N30A0 work on 50 Hz power infrastructure?
A: Yes. The input accepts 50/60 Hz, so the VP4N30A0 operates on both North American (60 Hz) and international (50 Hz) power systems. Input voltage range is 200–240V, compatible with 208V and 230V single-phase infrastructure.
The VP4N30A0 is a well-scoped unit for data center operators who need network-visible power monitoring on a 30A/208V branch circuit without giving up rack real estate. The 0U vertical form factor is the key differentiator here — in a fully-loaded 42U cabinet, you simply cannot afford to burn rack units on power infrastructure, and the rear-channel vertical mount solves that cleanly. The 36-outlet count with locking IEC connectors is appropriate for high-density mixed compute/networking racks where cable pull-out is a real operational risk.
Technical Highlights:
- Unit-Level Monitoring (Current, Voltage, Power): Simultaneous measurement of all three parameters gives you a complete power profile of the rack at any point in time — useful for both capacity planning and incident response when a circuit trips.
- SNMP v3 + Modbus TCP: SNMP v3 with auth/privacy satisfies most enterprise NMS security policies without exception requests; Modbus TCP bridges the IT/facilities gap, letting DCIM platforms pull rack power data alongside mechanical systems data.
- LDAP / RADIUS / TACACS+ AAA: Three enterprise authentication protocols on a PDU is unusual at this price tier — it means you can enforce role-based access to PDU management through your existing directory infrastructure rather than tracking per-device passwords in a spreadsheet.
Deployment Considerations:
- The NEMA L6-30P input requires a dedicated L6-30R branch circuit. Confirm your facility's PDU whip termination type before installation — a missing adapter on day one delays commissioning.
- Monitoring in the VP4N30A0 is at the unit level, not per-outlet. If your SLA requires per-outlet load visibility or the ability to remotely cycle individual outlets, you need a switched/outlet-metered variant — this model does not provide that capability.
The VP4N30A0 is the right specification for a mid-density co-location cage or enterprise IDF/MDF closet where a 30A/208V circuit is already provisioned, rack space is at a premium, and the operations team needs SNMP-visible power data without deploying a separate power monitoring appliance.
