Vertiv Rpdu Monitored Outlet Level EC 50A 208V Delta 14.4KW Vertical (48) Combina - VP6N50A4

Vertiv VP6N50A4 Monitored Outlet-Level PDU, 50A/208V, 48-Outlet Vertical 0U

Overview

The Vertiv VP6N50A4 is a 0U vertical rack PDU built for high-density data center cabinets and server rooms where outlet-level current visibility is non-negotiable. At 50A/208V with 14.4kW capacity and 48 combined C13/C19 outlets, it handles mixed server, storage, and networking loads in a single vertical unit — no wasted rack units, no compromising on monitoring depth. If your team tracks per-outlet power consumption for chargeback, capacity planning, or anomaly detection, the VP6N50A4 belongs on your shortlist of rack PDUs.

This unit ships as part of Vertiv's monitored outlet-level EC line, which sits above basic metered PDUs by providing granular per-outlet current and power readings — not just branch-level aggregates. Pair it with a UPS upstream and you have a complete power chain with visibility from the source to each individual cord.

Key Features

• 48 Outlets — C13 and C19 Mix: The combination of C13 and C19 receptacles means you can connect standard 1U servers alongside high-draw storage arrays and dual-corded UPS bypass loads without adapters. In practice, this eliminates the adapter-chain clutter that creates hot-spots and increases failure points in dense cabinets.
• 50A / 208V Delta Input — 14.4kW Usable Capacity: At 208V delta, the VP6N50A4 draws from three-phase distribution common in raised-floor and colocation environments. 14.4kW of usable capacity is enough to saturate a modern 42U cabinet running mid-density blade or 2U compute — without splitting load across two PDUs.
• Outlet-Level Current, Voltage, and Power Monitoring: Most metered PDUs report a single aggregate number per branch. This unit tracks current, voltage, and power at every outlet — so you know exactly which device is drawing 2.3A at 3 AM, not just that branch B is at 80% load. That granularity is what makes capacity planning and incident triage faster.
• Dual RJ-45 Ethernet with Daisy-Chain Support: Two Ethernet ports let you daisy-chain multiple PDUs on a single network drop, reducing cable runs and switch port consumption in large deployments. A single IP per PDU chain keeps your DCIM or NMS from being flooded with endpoint registrations.
• LCD Display: The onboard LCD gives local technicians immediate visibility into load status without logging into a web UI — useful during physical installs and cable hot-swap procedures where a laptop isn't always at hand.
• Protocol Stack — SNMP v1/v2c/v3, Modbus TCP, LDAP, RADIUS, TACACS+: SNMP v3 support means encrypted, authenticated polling — not cleartext SNMP v1 traps that most security auditors flag. LDAP, RADIUS, and TACACS+ integration lets you tie PDU access into your existing AAA infrastructure instead of managing local credentials on 40 devices. Modbus TCP extends compatibility to BMS and SCADA systems common in larger facilities.
• IPv4 and IPv6 Dual-Stack: Native IPv6 support means the VP6N50A4 doesn't become a migration blocker if your data center networking team is pushing v6 adoption. No NAT workarounds, no legacy addressing exceptions.
• 0U Vertical Mounting — 3m Cable: Vertical 0U form factor installs in the side channel of standard open-frame or enclosed racks, preserving every rack unit for compute. The 3-meter input cord gives enough reach for floor-to-cabinet runs in most raised-floor arrangements without extension cords.
• RSTP Network Redundancy: Rapid Spanning Tree Protocol support on the network interface means the PDU participates properly in redundant network topologies — no loops, no broadcast storms if your OOB network has redundant paths.
• Reset Button and LED Indicators: Hardware reset and per-outlet LED status indicators reduce remote troubleshooting time. When an LED goes amber or red, you know which outlet to investigate before opening a console session.

Integration and Compatibility

The VP6N50A4 integrates with any DCIM, NMS, or BMS platform that supports SNMP v1/v2c/v3 or Modbus TCP — which covers Vertiv's own Trellis platform, as well as third-party tools like Nlyte, Sunbird dcTrack, and most SNMP-capable monitoring stacks. SMTP and Syslog support mean alerts route directly to your ticketing system or SIEM without requiring a custom integration. HTTP/HTTPS access provides a browser-based management interface for environments where SNMP polling isn't the primary workflow. NTP synchronization ensures log timestamps align with the rest of your infrastructure — a small detail that matters when you're correlating power events with application logs during a post-incident review. For network infrastructure teams managing OOB access, the dual-port daisy-chain architecture keeps PDU management off your primary production network segments.

Frequently Asked Questions

Q: What outlet types does the VP6N50A4 provide, and how many of each?

A: The VP6N50A4 provides 48 total AC outlets combining C13 and C19 coupler types. The exact split between C13 and C19 receptacles is not specified in available documentation — confirm with the manufacturer or your distributor if the precise ratio matters for your load mix.

Q: Does the VP6N50A4 support three-phase 208V input?

A: Yes. The VP6N50A4 is rated for 208V delta input at 50A, which is consistent with three-phase distribution common in data center and colocation environments. Input frequency is 50/60 Hz for compatibility with both North American and international power infrastructure.

Q: Can multiple VP6N50A4 units be managed from a single IP address?

A: Yes. The unit includes dual RJ-45 Ethernet ports with daisy-chain support, allowing multiple PDUs to be networked together and managed under a reduced number of IP addresses — useful for minimizing switch port consumption and simplifying DCIM registration in large cabinet deployments.

Q: What network protocols does the VP6N50A4 support for monitoring and management?

A: The VP6N50A4 supports SNMP (v1, v2c, and v3), Modbus TCP, HTTP, HTTPS, LDAP, RADIUS, TACACS+, SMTP, Syslog, NTP, DHCP, IPv4, IPv6, SSH, and RSTP. This covers integration with most enterprise DCIM, NMS, BMS, and SIEM platforms without requiring custom protocol adapters.

Q: Does the VP6N50A4 require a dedicated rack unit?

A: No. The VP6N50A4 is a 0U vertical PDU designed to mount in the side channel of a standard rack, leaving all rack units available for compute, storage, and networking equipment. It ships with a 3-meter input cord.

Q: What is monitored at the outlet level on the VP6N50A4?

A: Each outlet is individually monitored for current, power, and voltage — not just aggregate branch-level readings. This per-outlet visibility supports chargeback accounting, capacity planning, and per-device anomaly detection without requiring external current measurement hardware.

Karl Wilson

The VP6N50A4's outlet-level monitoring is the spec that separates it from basic metered PDUs in high-density environments. When you're running 48 outlets across a mixed C13/C19 load at up to 50A and 14.4kW, knowing that branch B is at 78% capacity tells you nothing actionable — but knowing which specific outlet is drawing 4.2A and trending upward gives you the data to act before a breaker trips or a thermal event develops.

Technical Highlights:

• 14.4kW at 208V Delta: Three-phase 208V delta input is the standard in raised-floor colo and purpose-built data halls — this unit fits directly into that infrastructure at 50A without step-down transformers or input adapters, keeping the power chain clean.
• SNMP v3 + TACACS+ + LDAP: SNMP v3 gives you encrypted, authenticated polling — not the cleartext v1 traps that trigger findings on most security audits. LDAP and TACACS+ mean PDU credentials live in your directory, not in 40 separate local admin accounts that nobody rotates.
• Dual RJ-45 Daisy-Chain: In a 10-cabinet row, daisy-chaining VP6N50A4 units cuts your OOB switch port requirement significantly and simplifies IP allocation — one IP per chain rather than one per PDU is a real operational simplification at scale.

Deployment Considerations:

• The 3-meter input cord works for most standard cabinet heights, but verify your floor-to-cabinet run before ordering — in deep under-floor cable vaults or non-standard rack positions, you may need a cord extension or alternative whip length.
• The outlet-level monitoring generates substantially more SNMP polling data than branch-level PDUs — size your NMS polling intervals and database retention accordingly, especially if you're managing 20+ PDUs in a single DCIM instance.

The VP6N50A4 is the right PDU for colocation deployments and enterprise data halls where facility teams need per-tenant chargeback data and ops teams need per-device load visibility in the same unit — the protocol depth (Modbus TCP for BMS, SNMP v3 for NMS, LDAP/TACACS+ for AAA) means it integrates cleanly into a multi-team operational model without compromise.
