Vertiv Rpdu Switched Unit Level Monitoring EC 50A 208V Delta 14.4KW Vertical (12) - VP5N50A0

Vertiv VP5N50A0 Switched Vertical Rack PDU with Unit-Level Monitoring

Overview

The Vertiv VP5N50A0 is a switched, unit-level-monitored rack PDU built for high-density three-phase data center and critical-infrastructure deployments. Rated at 50A/208V Delta (14.4kW total capacity), this vertical 0U unit delivers 24 C13 outlets in a space-neutral profile that mounts flush against the rear of a standard cabinet — leaving every rack unit free for compute or networking gear. If you're running blade chassis, high-density 1U servers, or large UPS-backed rows in a co-location or enterprise machine room, the VP5N50A0 is sized to handle the load without leaving outlet headroom on the table.

Unlike basic metered PDUs, the VP5N50A0 supports switched control at the unit level, meaning you can remotely cycle power to the entire PDU without touching the cabinet — essential for lights-out facilities or branch-office IT closets where physical access is a managed event, not a quick walk.

Key Features

• 50A / 208V Three-Phase Delta Input, 14.4kW Capacity: Three-phase Delta wiring distributes load across phases rather than stacking it on a single leg — critical for keeping breaker margins safe on dense rows. At 14.4kW total, this PDU can absorb a full cabinet of dual-power-supply 1U servers without approaching the 80% derate threshold that good power-planning demands.
• 24 C13 Outlets: C13 connectors match the IEC standard power cords shipped with virtually every 1U/2U server, switch, and storage array. Twenty-four positions in a vertical 0U form factor means you're not burning rack-unit space on the PDU itself — the whole outlet strip lives in the cable management channel.
• Switched Unit-Level Control: Remote power cycling of the entire PDU through the web UI or SNMP eliminates the need for a KVM or on-site technician for hard-reboot scenarios. In lights-out co-location environments this alone justifies the switched-versus-monitored price step.
• Real-Time Monitoring — Current, Voltage, Power, Temperature: The VP5N50A0 tracks all four electrical and environmental parameters simultaneously. Watching current draw and voltage together lets you spot load imbalance before it trips a breaker; temperature monitoring at the PDU catches cooling problems before they become hardware failures.
• Dual RJ-45 Network Ports + Daisy Chain: Two Ethernet ports support daisy-chaining multiple PDUs on a single network drop, reducing IP address consumption and cable runs in large deployments. A single management connection can supervise an entire cabinet row.
• Enterprise Protocol Stack — SNMP v1/v2c/v3, HTTPS, SSH, LDAP, RADIUS, TACACS+, Modbus TCP: Every major NMS, DCIM platform, and security framework is covered. SNMP v3 delivers authenticated, encrypted traps — satisfying SOC 2 and ISO 27001 monitoring requirements without a separate protocol gateway. RADIUS and TACACS+ integration means PDU access follows your existing AAA infrastructure rather than a local username silo.
• IPv4 and IPv6 Dual-Stack: Future-proofing for environments migrating network addressing — no firmware upgrade required to operate in a pure IPv6 management network.
• LED Display + Reset Button: Local LED indicators provide at-a-glance status without requiring a laptop on the floor. The hardware reset button gives you a recovery path if firmware or network misconfiguration locks out remote access — useful during initial commissioning.
• 3-Meter Input Cord: The 3m (approximately 10 ft) input cable reaches from a vertical PDU position to a floor-level or overhead three-phase whip or PDU tap without requiring a cable extension — a practical detail that simplifies installation in standard 42U–48U cabinets.
• 200–240V Delta, 50/60Hz Input Range: Operates across the full international 200–240V Delta band at both 50Hz and 60Hz, making the VP5N50A0 deployable in US, European, and Asia-Pacific data centers without separate SKUs.
• USB Port: The onboard USB port supports firmware updates and configuration transfers via local media — reducing dependency on network connectivity during initial deployment or disaster recovery.
• Syslog, NTP, SMTP Alerting: Push power events and alarms directly to your SIEM or log aggregator via Syslog, synchronize timestamps across all PDUs via NTP, and get proactive email alerts via SMTP — all without a separate monitoring agent or collector appliance.

Integration & Compatibility

The VP5N50A0's protocol breadth — SNMP v1/v2c/v3, Modbus TCP, HTTP/HTTPS, and SSH — covers the major DCIM and building management platforms used in enterprise and co-location environments. SNMP MIB integration connects directly to tools like SolarWinds, PRTG, Nagios, and Vertiv's own Trellis DCIM. Modbus TCP extends compatibility to industrial BMS/SCADA systems common in manufacturing and utility environments.

Authentication delegates cleanly to existing infrastructure: LDAP for directory-based user management, RADIUS and TACACS+ for network-policy-enforced access control, and RSTP at the network layer for loop prevention in redundant management network topologies. IPv6 dual-stack means no NAT workarounds in environments that have deprecated IPv4 on management VLANs.

For large cabinet deployments, the daisy-chain capability on the dual RJ-45 ports allows multiple VP5N50A0 units to share a single network uplink, minimizing management switch port consumption. This is particularly useful in co-location cage environments where management port counts are licensed or physically constrained.

Frequently Asked Questions

Q: What input plug/connector does the VP5N50A0 use?

A: The VP5N50A0 is rated for 50A / 208V Delta three-phase input with a 3-meter input cord. The exact plug type should be confirmed with your facilities or electrical team based on your three-phase whip configuration — hardwire and specific plug options vary by installation. Check the Vertiv product page or your distributor's configurator for the specific inlet connector on this SKU.

Q: Can the VP5N50A0 switch individual outlets, or only the whole PDU?

A: Based on the product classification, the VP5N50A0 provides unit-level monitoring and switching — meaning the switched control operates at the PDU level, not per individual outlet. If per-outlet switching is required, consider a Vertiv outlet-switched PDU variant in the same family.

Q: How many PDUs can be daisy-chained together?

A: The VP5N50A0 includes dual RJ-45 ports and daisy-chain support. The maximum chain depth should be confirmed from the Vertiv installation guide for this model, as chain limits vary by firmware version and network topology.

Q: Does the VP5N50A0 support SNMP v3 with encryption?

A: Yes. The VP5N50A0 supports SNMP v1, v2c, and v3. SNMP v3 includes authentication and privacy (encryption) options, satisfying requirements for encrypted management traffic in security-conscious environments.

Q: Is the VP5N50A0 compatible with third-party DCIM platforms?

A: The VP5N50A0 supports SNMP v1/v2c/v3 and Modbus TCP, which are the primary protocols used by major DCIM platforms including SolarWinds, PRTG, Nagios, and Vertiv Trellis. Confirm specific MIB file availability with Vertiv support for your DCIM version.

Q: What environmental monitoring does the VP5N50A0 include built-in?

A: The VP5N50A0 monitors current, voltage, power, and temperature natively. External environmental sensor support (humidity, door contact) depends on available sensor ports — consult the Vertiv spec sheet for sensor port details on this SKU.

When I spec a switched PDU for a lights-out co-location row or a remote branch IDF, the first thing I check is the protocol stack — and the VP5N50A0 covers the full enterprise stack: SNMP v3 with encryption, HTTPS, SSH, RADIUS, TACACS+, and LDAP. That's not common at every price point. At 50A / 208V Delta three-phase with 14.4kW capacity, this unit is sized for blade-dense or GPU-heavy cabinets where you need both load headroom and authenticated remote control.

Technical Highlights:

• Three-Phase Delta, 50A / 14.4kW: Three-phase distribution keeps individual phase loads balanced — at 50A input, you have meaningful overhead before hitting the 80% derate threshold on most facility circuits. That headroom matters when cabinets have uneven power-supply load distributions across dual-corded servers.
• SNMP v3 + RADIUS/TACACS+ + Modbus TCP: SNMP v3 satisfies encrypted-management requirements for SOC 2 and ISO 27001 audits without an add-on gateway. RADIUS and TACACS+ tie PDU authentication directly into your AAA policy — no separate local account sprawl across 20 PDUs in a cage. Modbus TCP extends reach into BMS/SCADA systems common in industrial and utility deployments.
• Dual RJ-45 with Daisy Chain: Two network ports let you chain multiple PDUs on a single management uplink. In co-location environments where management switch ports are metered or physically limited, this directly reduces operational overhead and port licensing costs.

Deployment Considerations:

• Unit-level switching means the remote power-cycle operates on the whole PDU, not individual outlets — if your use case requires per-outlet reboot control (e.g., cycling a single server without affecting the rest of the cabinet), spec the outlet-switched variant in the Vertiv Geist family instead.
• The 200–240V Delta input range covers international deployments, but confirm your facility's three-phase whip and inlet connector type before ordering — the 3m input cord is fixed-length and the inlet configuration varies by region/SKU within this family.

The VP5N50A0 is the right call for enterprise co-location rows, dense compute cabinets, and remote IDF closets where you need authenticated, encrypted PDU management and three-phase load distribution — particularly in environments where your DCIM or NMS already speaks SNMP v3 or Modbus TCP.
