Vertiv Rpdu Switched Outlet Level Monitoring EC 16A or 20A 120V or 208V or 230V 1.9 - VP7U21A0

Vertiv VP7U21A0 Switched Outlet-Level Monitoring PDU

Overview

The Vertiv VP7U21A0 is a 0U horizontal switched PDU engineered for dense rack environments where per-outlet power visibility and remote control aren't optional — they're operational requirements. Rated for 16A or 20A single-phase input at 100–240V (50/60 Hz), it accepts a wide voltage range that makes it equally deployable in North American 120V data closets or European 230V server rooms without a hardware swap. Twelve IEC C13 and C19 outlets give you the mix of standard and high-draw connections needed when a rack holds both 1U servers and higher-wattage storage or networking gear. The C20 inlet plug means you're connecting directly to a standard PDU-rated circuit — no adapters, no improvised wiring.

The 3-meter cable run keeps the unit positioned cleanly in a 0U vertical or horizontal mount without straining the cord to your panels, and the built-in LCD display lets you read current, voltage, and power readings locally without pulling up a browser or SSH session.

Key Features

• Switched outlet-level control: Each outlet can be individually switched on, off, or power-cycled remotely — critical for rebooting a hung device in a remote rack without dispatching a technician. In distributed edge deployments or colocation environments, that's the difference between a 5-minute remote fix and a 2-hour truck roll.
• Per-outlet current, voltage, and power monitoring: The VP7U21A0 tracks current, voltage, and real power at the outlet level, not just at the inlet. That granularity lets you spot a misbehaving UPS battery charger or a VM host drawing more than its provisioned load before it trips a breaker.
• 12 mixed C13/C19 outlets: C13 handles standard IEC server and switch loads; C19 supports higher-wattage devices up to 16A per outlet. A mixed outlet layout means you don't need a separate high-density PDU just because one device in the rack has a C20 power cord.
• 100–240V, 50/60 Hz universal input: The wide input range means this PDU ships and installs globally without voltage-specific SKUs. Useful for organizations standardizing equipment across multiple data center regions.
• 0U horizontal mount, 3m cable: Zero rack unit footprint preserves usable server space. The 3-meter factory cable provides enough reach in standard 42U–48U rack installations without extensions.
• LCD display with LED indicators: Local readout of live electrical parameters at the unit — useful during commissioning or when network access is unavailable. LED indicators flag alarm conditions without needing a management connection.
• SNMP v1/v2c/v3, HTTPS, SSH, Syslog, SMTP: Full enterprise protocol suite means this PDU integrates with DCIM platforms, SNMP-based NMS tools, and security information systems without middleware. SNMP v3 provides authenticated, encrypted polling for environments with strict network security policies.
• LDAP, RADIUS, TACACS+ authentication: Centralizes access control through your existing directory or AAA infrastructure — no managing local PDU credentials independently across dozens of units.
• IPv4/IPv6, DHCP, NTP support: Dual-stack networking future-proofs the deployment in IPv6 environments; NTP synchronizes alarm timestamps across all PDUs in a facility for accurate correlation in SIEM or DCIM logs.
• Modbus TCP: Enables integration with building management systems (BMS) and industrial SCADA platforms — relevant for edge deployments in manufacturing or utilities where the rack lives alongside process control infrastructure.
• Single RJ-45 Ethernet + USB + serial port: One network port for management traffic keeps the configuration clean. The USB and serial ports support local console access and firmware updates without network dependency.

Integration & Compatibility

The VP7U21A0 speaks a broad protocol stack — rack PDU management platforms that rely on SNMP v3 polling, Syslog forwarding, or SMTP alerting will integrate without custom drivers. LDAP and RADIUS support means this unit slots into enterprise authentication frameworks running Active Directory or FreeRADIUS. The Modbus TCP interface makes it accessible to building automation and Vertiv infrastructure management tools designed for mixed IT/OT environments. If you're running a managed network switch infrastructure with SNMP-based monitoring, the same NMS console that monitors your switches can poll outlet-level power data from this PDU with no separate tooling. For organizations evaluating rack power distribution at scale, the combination of outlet-level switching and per-outlet metering in a 0U footprint is the key differentiator over basic monitored-only units.

Frequently Asked Questions

Q: What is the input current rating for the VP7U21A0, and does it support both 120V and 230V environments?

A: The VP7U21A0 supports 16A or 20A single-phase input at 100–240V, 50/60 Hz. This universal input range makes it compatible with both 120V North American circuits and 208V or 230V international installations without requiring a separate model.

Q: Can I control individual outlets remotely on the VP7U21A0?

A: Yes. This is a switched PDU with outlet-level monitoring, meaning each outlet can be individually powered on, off, or power-cycled via the network management interface. This allows remote reboot of individual devices without affecting others in the rack.

Q: What outlet types does the VP7U21A0 provide?

A: The VP7U21A0 provides 12 IEC outlets in a mix of C13 (standard load) and C19 (high-current) types. The inlet uses a C20 coupler, compatible with standard 16A/20A PDU power whips.

Q: Which network management protocols does the VP7U21A0 support?

A: Supported protocols include SNMP v1/v2c/v3, HTTPS, HTTP, SSH, SMTP, Syslog, LDAP, RADIUS, TACACS+, DHCP, NTP, IPv4, IPv6, RSTP, and Modbus TCP. This covers integration with enterprise NMS platforms, DCIM tools, AAA authentication systems, and building management systems.

Q: Does the VP7U21A0 take up rack unit space?

A: No. The VP7U21A0 is a 0U PDU designed for horizontal mounting, meaning it does not consume usable rack unit space. The unit includes a 3-meter factory cable for installation flexibility.

Q: What power parameters can the VP7U21A0 monitor at the outlet level?

A: The VP7U21A0 monitors current, power, and voltage at the outlet level — not just at the inlet. This granular metering allows you to track per-device power consumption and detect anomalies before they cause a circuit fault.

Ted Perry

The VP7U21A0 stands out in the switched PDU category primarily because of its outlet-level metering — current, voltage, and power per outlet, not just inlet-level totals. That distinction matters when you're troubleshooting a rack where three different teams own different devices and you need to pinpoint which one is drawing anomalous load without pulling cables or guessing.

Technical Highlights:

• Universal 100–240V input: Eliminates the need for region-specific PDU inventory. A single model deploys across 120V US branch circuits and 230V EU or APAC installations — relevant for organizations managing distributed racks across multiple geographies.
• SNMP v3 with LDAP/RADIUS/TACACS+ auth: SNMP v3's authenticated encrypted polling means this PDU meets the same network security posture as your managed switches. Pairing that with centralized AAA authentication removes the credential management burden when you're running 20+ PDUs across a data center floor.
• Modbus TCP protocol support: Most switched PDUs stop at SNMP. The Modbus TCP stack on this unit opens a direct integration path to BMS and SCADA platforms — useful in edge deployments where the same rack might be monitored by both IT and facilities teams using different toolsets.

Deployment Considerations:

• The C20 inlet requires a matching power whip from your panel or UPS output — verify your UPS output receptacle type before ordering. Most enterprise UPS units ship with C19/C20 whips, but older installations may need an adapter or replacement whip.
• The 0U horizontal form factor assumes available horizontal cable management space in the rack. In fully populated 42U racks with dense patch panel runs, confirm there's a clean horizontal path for the 3-meter cord before committing to this mount orientation over a vertical 0U installation.

The VP7U21A0 is the right specification for colocation tenants or enterprise IT teams managing remote racks where outlet-level reboot capability and per-device power accountability — combined with SNMP v3 and AAA integration — are non-negotiable operational requirements rather than nice-to-haves.
