Vertiv Rpdu Switched Outlet Level Monitoring EC 35A 208V Delta 10.0KW Vertical (3 - VP7N40A1

Vertiv VP7N40A1 Switched Outlet-Level Monitoring PDU, 35A 208V 10kW Vertical

Overview

The Vertiv VP7N40A1 is a 0U vertical rack PDU built for data center managers and facilities engineers who need granular, outlet-by-outlet power control and real-time monitoring in a high-density cabinet. Drawing up to 35A at 200–240V (three-phase delta, 10.0kW), this switched PDU gives operators the ability to remotely cycle any of its 36 outlets without touching the physical rack — a practical necessity in co-location environments, remote edge deployments, or any situation where hands-on access is costly or slow. The VP7N40A1 ships in vertical form factor at 0U, so it occupies zero rack unit space while mounting flush to the inside rail of a standard cabinet.

Key Features

• 36 Switched Outlets (C13 + C19): The VP7N40A1 provides a mixed outlet bank — C13 couplers for 1U servers, switches, and 1U appliances; C19 couplers for high-draw PDU-fed devices and higher-wattage servers. Mixing both types on one PDU means you don't need a second unit to cover your high-current nodes, which keeps cable runs clean and reduces per-cabinet cost.
• 35A / 10.0kW Input at 208V Three-Phase Delta: Rated for 35A continuous at 200–240V, this PDU is engineered for dense compute cabinets running at or near full load. The 10kW ceiling covers most mid-density blade and 1U server deployments without requiring a second circuit, reducing your electrical infrastructure overhead per cabinet.
• Outlet-Level Switching: Each outlet can be toggled independently via network command — power-cycle a hung server, schedule a maintenance window reboot, or sequence startup after a power event, all without dispatching a technician. This is the key distinction over a monitored-only PDU: you get actuation, not just visibility.
• Current, Power, and Voltage Monitoring: Real-time per-outlet monitoring of current (A), power (W), and voltage (V) means you can identify which devices are drawing unexpectedly, catch load imbalances before a breaker trips, and generate accurate per-tenant power billing data in co-lo environments — none of which is possible with a basic non-monitored strip.
• SNMP v1/v2c/v3 + Modbus TCP + Full Protocol Suite: The VP7N40A1 speaks SNMP (all three versions), Modbus TCP, HTTPS, SSH, LDAP, RADIUS, TACACS+, NTP, and Syslog. This breadth of protocol support means it integrates with enterprise DCIM platforms, SIEM pipelines, and SNMP-based NMS tools without middleware or custom scripting. SNMPv3 with authentication and encryption is available for environments with strict security posture requirements.
• Dual RJ-45 Ethernet Ports with Daisy-Chaining: Two Ethernet ports allow daisy-chaining multiple PDUs on a single network drop — useful in high-density deployments where running individual network connections to every PDU in a row of cabinets is impractical. This topology reduces switch port consumption and simplifies cable management in the network overhead.
• LCD Display with LED Indicators: The onboard LCD provides local readout of critical parameters without requiring a laptop or network connection — useful during initial commissioning, physical inspections, or network-down scenarios. LED indicators give at-a-glance status without navigating a menu.
• 3-Meter Input Cable: The 3m power cord provides enough reach for standard cabinet placements without an extension, covering both top-of-cabinet and floor-level PDU panel connections typical in raised-floor data center environments.
• IPv6 Ready: Native IPv6 support future-proofs the PDU for data centers migrating away from IPv4-only management networks, including government and enterprise environments with mandated IPv6 adoption timelines.
• 0U Vertical Mounting: By mounting vertically inside the cabinet rail, the VP7N40A1 consumes no rack unit space — every U in the cabinet stays available for compute, storage, or networking gear. Vertical PDUs also position outlets closer to device power inputs, reducing internal cable clutter.

Integration and Compatibility

The VP7N40A1 is designed to slot into existing Vertiv power management infrastructure and third-party DCIM platforms alike. Its SNMP v3 and Modbus TCP support covers the two dominant protocols used by enterprise-grade rack PDU management and building management systems. LDAP and RADIUS/TACACS+ integration means user authentication ties directly into your existing directory or AAA infrastructure — no separate credential store to manage on the PDU itself. The dual-port daisy-chain topology is particularly well-suited to structured data center power distribution deployments where network cabling per PDU is constrained. For environments planning capacity expansion, the daisy-chain capability supports scaling outlet coverage within a row without adding switch ports. Pair this PDU with an appropriate UPS system upstream to complete a monitored and protected power chain from input to outlet.

Frequently Asked Questions

Q: What outlet types does the VP7N40A1 provide, and how many of each?

A: The VP7N40A1 has 36 total AC outlets in a mix of C13 and C19 coupler types. C13 outlets handle standard 1U server and networking gear; C19 outlets support higher-current devices. The exact C13/C19 split should be confirmed with the product datasheet or Vertiv configuration guide for this SKU.

Q: Can the VP7N40A1 be managed remotely, and what protocols does it support?

A: Yes. The VP7N40A1 supports remote management via SNMP (v1, v2c, and v3), HTTPS, SSH, Modbus TCP, and Syslog. It also integrates with LDAP, RADIUS, and TACACS+ for enterprise authentication. Both IPv4 and IPv6 are supported.

Q: What is the maximum power capacity of the VP7N40A1?

A: The VP7N40A1 is rated at 35A maximum current with a 10.0kW power capacity at 208V (three-phase delta, 200–240V input range, 50/60 Hz).

Q: Does the VP7N40A1 support daisy-chaining multiple PDUs?

A: Yes. It includes two RJ-45 Ethernet ports specifically to support daisy-chaining — connecting multiple PDUs in sequence over a single network drop, reducing switch port consumption in row-based cabinet deployments.

Q: Does the VP7N40A1 take up rack unit space?

A: No. The VP7N40A1 is a 0U vertical PDU. It mounts inside the cabinet rail vertically, occupying no rack units and leaving all U-space available for compute and networking equipment.

Q: What monitoring parameters are available at the outlet level?

A: The VP7N40A1 monitors current (amps), power (watts), and voltage (volts) — enabling per-outlet load visibility, capacity planning, and power usage reporting for individual devices or tenants.

Karl Wilson

The VP7N40A1 addresses a specific operational pain point I see repeatedly in co-location and enterprise data center deployments: you need per-outlet switching at 35A three-phase, not just monitoring, and you need it without burning a single rack unit. Vertiv's vertical 0U form factor here is genuinely useful — in a fully loaded 42U cabinet, every U counts, and a switched PDU that disappears into the rail rather than occupying 1–2U of prime real estate is the right engineering call.

Technical Highlights:

• SNMPv3 with LDAP/RADIUS/TACACS+: Most operators stop at SNMP v2c. Having v3 with authentication and encryption, combined with directory-integrated user auth via LDAP or RADIUS/TACACS+, means the PDU fits inside a Zero Trust network access model without carving out exceptions — important for FedRAMP-adjacent and enterprise security programs.
• 35A / 10kW at 208V Three-Phase: This PDU is correctly sized for mid-density compute rows — think 10–15 1U servers plus a few storage nodes per cabinet. At 35A, you're drawing close to the practical continuous load ceiling for a 208V three-phase 40A circuit (80% rule), so no headroom is wasted on oversized infrastructure.
• Dual RJ-45 Daisy-Chain: Two Ethernet ports aren't just redundancy — they're a topology feature. In a 10-cabinet row, you can run one network drop to the first PDU and daisy-chain the rest, saving 9 switch ports. At scale across multiple rows, that's meaningful switch infrastructure reduction.

Deployment Considerations:

• The 3m input cable is sufficient for most raised-floor environments where the PDU panel is at the base of the cabinet, but verify your panel-to-cabinet distance before ordering — a short cable in a custom build-out forces an expensive field fix.
• The C13/C19 outlet mix is the right call for most compute deployments, but confirm the exact per-type count from the Vertiv configuration guide before committing this unit to a build with a specific high-C19-count device mix (e.g., all high-draw GPU nodes).

The VP7N40A1 is the correct specification for co-location providers deploying metered, switched power in a customer cabinet environment — outlet-level monitoring feeds per-tenant billing, outlet-level switching enables remote troubleshooting without dispatch, and the 0U form factor preserves every sellable rack unit in the cabinet.
