Vertiv Rpdu Switched Unit Level Monitoring EC 35A 208V Delta 10.0KW Horizontal (1 - VP5N41A0

Vertiv VP5N41A0 Switched Three-Phase Horizontal Rack PDU

Overview

The Vertiv VP5N41A0 is a switched, three-phase horizontal rack PDU rated at 35A and 208V delta, delivering up to 10.0kW of managed power across 12 outlets in a 0U horizontal footprint. It's built for data center racks and colocation environments where administrators need remote outlet-level control — the ability to sequence power, hard-reboot hung servers, and cut individual circuits without touching the rack. If your ops team needs to manage power from a NOC or across a distributed campus, this is the class of PDU that makes that possible.

The VP5N41A0 ships with a 3-meter input cord, an LED display for at-a-glance load monitoring, and a network stack broad enough to drop into virtually any enterprise environment without friction.

Key Features

• Outlet-Level Switching (12 Outlets, C13 + C19 Mix): Each of the 12 outlets can be individually switched on, off, or sequenced remotely — critical for avoiding simultaneous inrush when powering up a dense rack. The mix of C13 and C19 receptacles covers both 1U servers and high-draw storage arrays or UPS bypass loads without adapter clutter.
• 35A / 208V Delta Three-Phase Input, 10.0kW: At 35A on a 208V delta three-phase feed, this unit handles up to 10.0kW of real load — enough for a fully populated high-density compute rack. Three-phase distribution also balances current across your branch circuits, reducing the risk of a single-phase panel overload in a mixed-server environment.
• Current, Power, and Voltage Monitoring at the Unit Level: Real-time monitoring of all three parameters means you can trend load over time, catch a circuit climbing toward capacity before it trips, and generate the billing-grade data that colocation operators need for per-tenant power reporting. This isn't just threshold alerting — it's continuous visibility.
• Comprehensive Protocol Stack — SNMP v1/v2c/v3, Modbus TCP, LDAP, TACACS+, RADIUS: SNMP v3 provides encrypted, authenticated polling so your NMS gets accurate data without exposing credentials. LDAP, TACACS+, and RADIUS integration means you can authenticate PDU management access against your existing directory — no separate credential silo to maintain. Modbus TCP opens a path to BMS and DCIM platforms that speak industrial protocols.
• IPv4 and IPv6 Dual-Stack Networking: Dual-stack support means you're not blocked by a legacy-only management network. Deploy today in an IPv4 environment and carry the PDU forward into a pure IPv6 infrastructure without a forklift swap.
• SSH, HTTPS, and Syslog for Secure Remote Management: SSH and HTTPS encrypt all management sessions in transit. Syslog integration funnels PDU events directly into your SIEM or log aggregator — outlet state changes, authentication events, and load alarms all land in the same audit trail as the rest of your infrastructure.
• NTP Time Synchronization: NTP-synced timestamps on all logged events mean your audit trail holds up under scrutiny. When a server loses power at 2:47 AM and you're tracing the cause six hours later, accurate event timestamps are non-negotiable.
• LED Display for Local Visibility: The front-panel LED display shows load at a glance without requiring a laptop or network connection — useful during physical installs, maintenance windows, or whenever the network path to the PDU is unavailable.
• 1x RJ-45 Ethernet, 1x USB, 1x Serial Port: The RJ-45 port handles primary network management. The USB port supports firmware updates or local config import/export without a serial console. The serial port provides an out-of-band management path when the network interface is unreachable.
• 3-Meter Input Cord: The 3m (approximately 9.8 ft) cord gives enough reach to connect to a floor-level power distribution panel or overhead bus without an extension — a practical detail that saves a service call during initial rack installation.
• 50/60 Hz Dual-Frequency Support: Compatible with both North American 60 Hz and international 50 Hz facility power, which matters for equipment that moves between data centers or for global deployments sourced from a single SKU.

Integration and Compatibility

The VP5N41A0 integrates with rack PDU management platforms via SNMP v1/v2c/v3 — compatible with leading DCIM tools, NMS platforms, and BMS systems through Modbus TCP. LDAP, RADIUS, and TACACS+ authentication hooks align with enterprise AAA infrastructure. HTTP and HTTPS access supports browser-based management without a dedicated client application. The unit's RSTP support enables resilient network topologies where the management network itself has redundant paths. Pair this PDU with a compatible UPS from the Vertiv power management line for a fully monitored power chain from utility input to individual outlet. For high-density compute deployments, review the rack PDU selection guide to match inlet configuration and current rating to your panel's branch circuit capacity before ordering. Three-phase delta input at 208V requires a compatible three-phase panel or RPP — confirm your facility's wiring configuration against the VP5N41A0's inlet spec before installation.

Frequently Asked Questions

Q: What input voltage and phase configuration does the VP5N41A0 require?

A: The VP5N41A0 requires a 208V delta three-phase input rated at 35A. It supports 50/60 Hz and is not compatible with single-phase panel feeds. Confirm your facility's branch circuit and panel configuration before installation.

Q: Can I switch individual outlets remotely on the VP5N41A0?

A: Yes. The VP5N41A0 is a switched PDU with outlet-level control across all 12 receptacles (C13 and C19 mix). Each outlet can be turned on, off, or sequenced independently via the network management interface.

Q: What network protocols does the VP5N41A0 support for management?

A: The VP5N41A0 supports SNMP v1/v2c/v3, HTTP, HTTPS, SSH, DHCP, NTP, SMTP, Syslog, LDAP, RADIUS, TACACS+, Modbus TCP, RSTP, and both IPv4 and IPv6.

Q: Does the VP5N41A0 support enterprise authentication (LDAP, RADIUS, TACACS+)?

A: Yes. All three enterprise AAA protocols — LDAP, RADIUS, and TACACS+ — are supported natively, allowing management access to be authenticated against your existing directory infrastructure.

Q: What does the VP5N41A0 monitor at the unit level?

A: The unit monitors current (amps), power (watts/kW), and voltage continuously. This data is accessible via SNMP, the web interface, and the front-panel LED display.

Q: What is the rack mounting orientation of the VP5N41A0?

A: The VP5N41A0 is a horizontal (0U footprint in standard horizontal orientation) mount PDU designed for installation in a standard 19-inch equipment rack.

James Everett

The VP5N41A0 is a unit I'd spec without hesitation into a high-density colocation bay or a managed hosting rack where the ops team needs hard power-cycle capability without a hands-and-eyes dispatch. The 35A three-phase delta input at 208V means you're drawing balanced current across all three legs — that's what keeps your branch circuit breakers from nuisance-tripping in a dense compute environment, and 10.0kW of usable capacity covers a fully populated 42U rack of modern 1U/2U servers without headroom anxiety.

Technical Highlights:

• SNMP v3 with LDAP/TACACS+/RADIUS: Encrypted SNMP polling plus directory-integrated authentication closes the two most common PDU security gaps simultaneously — no cleartext credentials in transit, no orphaned local accounts when staff turns over.
• Modbus TCP Support: Opens direct integration with DCIM and BMS platforms that speak industrial protocols. If your facilities team runs a building management system alongside your IT infrastructure, this is the protocol that bridges them without a middleware translator.
• 12 Switched Outlets — C13 + C19 Mix: Outlet-level switching on a mixed C13/C19 strip means you can sequence power-up order across mixed-density loads (1U servers on C13, storage heads on C19) in a single PDU pass, rather than managing two separate PDUs.

Deployment Considerations:

• The 208V delta three-phase input is a hard facility prerequisite — confirm your RPP or panel delivers delta (not wye) at 208V before racking this unit. A wye-configured panel at 208V line-to-neutral is not the same circuit, and the inlet spec is not forgiving on this point.
• The 3-meter cord is fixed length — measure your rack-to-panel distance before installation. In overhead busway deployments or floor PDU configs where the panel is more than ~9 feet away, you'll need to account for cord routing rather than assuming it reaches.

The VP5N41A0 is the right call for managed colocation operators, enterprise data center teams, and hosting providers who need per-outlet control, DCIM-ready monitoring, and AAA-integrated security in a single horizontal PDU — and who are running a three-phase 208V delta infrastructure to support it.
