Vertiv VP6N30A4 Monitored Outlet-Level Vertical PDU, 30A 3-Phase, 8.6kW
Overview
The Vertiv VP6N30A4 is a three-phase, outlet-level monitored power distribution unit designed for high-density vertical rack deployments where granular load visibility across every receptacle matters. Rated at 30A input via a NEMA L21-30P plug and capable of distributing up to 8.6kW across a mixed outlet bank of C13, C19, and NEMA 5-20R receptacles, this unit targets data center aisles, colocation deployments, and enterprise server rooms where per-outlet current monitoring translates directly into capacity planning accuracy and faster fault isolation. It occupies zero rack units — the vertical 0U form factor keeps all 42U of your rack available for revenue-generating gear.
Unlike branch-level or inlet-only PDUs, the VP6N30A4 delivers current, voltage, and power monitoring at the individual outlet level. That distinction matters in multi-tenant colo environments where you need to charge-back by rack position, or in any facility where a single overloaded circuit can cascade into unplanned downtime.
Key Features
- Outlet-Level Monitoring (Current, Voltage, Power): Visibility at every receptacle — not just at the inlet — means you can identify which specific device is pulling anomalous power without walking the floor or pulling cables. In a dense blade environment, this collapses troubleshooting time from hours to minutes.
- 30A / 8.6kW Three-Phase Input (NEMA L21-30P): The L21-30P plug connects to 120/208V WYE three-phase circuits, distributing load across all three legs. Balanced phase loading is the single biggest factor in avoiding nuisance breaker trips in high-density rows — this PDU gives you the data to achieve it.
- 24 Locking C13 Outlets: The lock-in receptacle design prevents accidental disconnection under vibration or cable pull — a meaningful safeguard in busy server rooms where cable management isn't always perfect. Locking connectors also simplify compliance audits by eliminating unintended plug removals.
- Mixed Outlet Bank (C13, C19, NEMA 5-20R): A combination of IEC C13 couplers for standard 1U servers, C19 couplers for high-draw PDUs and large UPS outputs, and NEMA 5-20R for legacy or KVM/console equipment means you're not forced to use adapters across a mixed fleet — adapters introduce additional failure points and clutter.
- Comprehensive Network Protocol Stack: SNMP v1/v2c/v3, Modbus TCP, LDAP, RADIUS, TACACS+, SSH, HTTPS, and Syslog support means the VP6N30A4 integrates into virtually any enterprise monitoring stack — from legacy SNMP trap receivers to modern DCIM platforms. TACACS+ and RADIUS enable centralized authentication, eliminating per-device credential management at scale.
- LED Display: The onboard LED indicator panel provides at-a-glance load status without requiring a network connection — useful during initial commissioning or in the event of a network outage when you still need local power confirmation.
- IPv4/IPv6 Dual-Stack Networking: Native IPv6 support future-proofs the management plane. As facilities migrate network infrastructure, you won't be stuck maintaining a separate VLAN or NAT policy just for PDU management traffic.
- Single RJ-45 Management Port + USB: One Ethernet management interface keeps network switch port consumption minimal. The USB port supports local configuration, firmware updates, or console access without requiring a laptop with a serial adapter.
- 3-Meter Power Cord: The 3m (approximately 10 ft) cord provides enough slack for overhead or underfloor routing to the distribution panel without requiring a cord extension — cord extensions in power paths introduce additional connectors and potential failure points.
- 100–120/200–240V Input Range at 50/60Hz: The wide input voltage window and dual-frequency support make this unit deployable in both North American 60Hz facilities and international 50Hz data centers without hardware modification.
Integration and Compatibility
The VP6N30A4 supports SNMP v1, v2c, and v3 natively, making it compatible with DCIM platforms, BMS systems, and general-purpose NMS tools including SolarWinds, PRTG, Nagios, and comparable enterprise monitoring environments. Modbus TCP extends compatibility to building automation controllers that don't speak SNMP. LDAP, RADIUS, and TACACS+ authentication integration fits Active Directory and TACACS server environments common in enterprise IT and colocation facilities.
The NTP protocol support ensures timestamped event logs and syslog entries align with your facility's time source — critical for correlating power events with server logs during incident post-mortems. SMTP support enables direct email alerting without requiring a separate alerting middleware layer.
The vertical 0U mounting profile is compatible with standard 19-inch two-post and four-post open-frame racks as well as enclosed cabinets with side-mount PDU channels. Verify your cabinet's vertical PDU mounting rail spacing before ordering — not all enclosed rack models include side-channel PDU mounting hardware.
Frequently Asked Questions
Q: What plug type does the VP6N30A4 use, and what panel circuit does it require?
A: The VP6N30A4 uses a NEMA L21-30P plug and requires a 30A three-phase 120/208V WYE circuit. This is a standard three-phase locking plug found on most data center and colocation PDU branch circuits rated for high-density rows.
Q: Does the VP6N30A4 monitor at the outlet level or only at the inlet?
A: Outlet-level monitoring. The VP6N30A4 tracks current, voltage, and power at each individual receptacle — not just at the PDU inlet. This enables per-device load visibility, charge-back metering by rack position, and faster fault isolation without physical inspection.
Q: What outlet types are included, and how many?
A: The unit provides a mix of IEC C13 couplers (including 24 with locking retention), IEC C19 couplers, and NEMA 5-20R receptacles for a total of 36 AC outlets. The locking C13 connectors prevent accidental disconnection in high-traffic environments.
Q: Which network management protocols does the VP6N30A4 support?
A: SNMP v1/v2c/v3, Modbus TCP, LDAP, RADIUS, TACACS+, SSH, HTTPS, HTTP, DHCP, IPv4, IPv6, NTP, RSTP, SMTP, and Syslog. This covers integration with DCIM platforms, building automation systems, SNMP-based NMS tools, and enterprise AAA authentication servers.
Q: Can this PDU be deployed in international (non-US) data centers?
A: The input accepts 100–120V and 200–240V at both 50Hz and 60Hz, which covers North American and most international facility voltages. Verify local three-phase distribution and plug compatibility — the NEMA L21-30P is a North American standard and may require a local adapter or panel modification in other regions.
Q: What mounting orientation does the VP6N30A4 use?
A: Vertical, 0U. It mounts in the vertical side channel of a standard 19-inch rack or cabinet, consuming no horizontal rack unit space. Confirm your rack or cabinet has vertical PDU mounting rails or brackets before installation.
The VP6N30A4 is the unit I reach for when a client needs true per-outlet accountability in a high-density three-phase row — not just inlet metering dressed up as monitoring. The combination of outlet-level current, voltage, and power tracking across 36 receptacles on a single 30A L21-30P feed is what separates this from basic monitored PDUs that only tell you what's happening at the breaker, not at the device.
Technical Highlights:
- SNMP v3 + TACACS+ + RADIUS: These three together mean the PDU slots into enterprise AAA infrastructure without exceptions or workarounds — no shared SNMP community strings sitting in plain text, no local-only credentials creating audit gaps.
- 36 Mixed Outlets (C13/C19/NEMA 5-20R): Real mixed fleets — 1U servers, GPU nodes, KVM switches, legacy console servers — don't standardize on a single connector. The outlet mix here covers most deployments without an adapter chain that eats into your safety margin.
- 8.6kW / 30A Three-Phase Input: At 208V WYE, balanced three-phase loading across a 30A feed is the right design point for a fully-loaded half-rack of 1U servers. Push past ~80% sustained and you're triggering breakers — the per-outlet visibility on this unit is what lets you stay under that threshold confidently.
Deployment Considerations:
- Vertical 0U mounting requires your cabinet to have a dedicated PDU side-mount channel or vertical rail bracket — not all enclosed racks include this hardware. Confirm before the unit arrives on site.
- The 3m cord is adequate for most overhead panel drops, but in deep cabinets with underfloor routing you may land short. Measure your panel-to-PDU run before assuming the cord reaches.
For a colocation facility managing multi-tenant rows where each rack position needs independent power accountability and the management plane has to integrate with existing RADIUS or TACACS+ AAA — the VP6N30A4 is a direct fit. It's not the unit for a small single-tenant closet where a basic metered PDU covers the use case.
