Vertiv VA7U11A0 Switched Rack PDU with Transfer Switch and Outlet-Level Monitoring

Overview

The Vertiv VA7U11A0 is a 0U vertical rack PDU that combines switched outlet control with a rack transfer switch and outlet-level current, voltage, and power monitoring in a single zero-rack-unit footprint. Designed for dense data center and network closet environments where horizontal rack space is at a premium, it mounts vertically along the rear rail and keeps every kilowatt-hour visible and every outlet individually controllable from the network. If you're managing power for critical IT loads — servers, storage arrays, network gear — and you need both the ability to reboot remotely and verified confidence that each outlet is drawing what it should, the VA7U11A0 is the unit to evaluate.

Key Features

• Switched Outlet Control (6 x C13): Each of the six C13 outlets can be independently switched on, off, or power-cycled via the network interface. That means a hung server can be rebooted without dispatching a technician — critical in remote or lights-out deployments where a truck roll costs more than the PDU itself.
• Rack Transfer Switch Built-In: The VA7U11A0 integrates a rack-level automatic transfer switch function, allowing the unit to source power from a primary feed and shift to a secondary feed on loss of input. For single-corded equipment in a dual-feed rack, this eliminates the need for a separate ATS device and reduces per-rack hardware count.
• Outlet-Level Current, Voltage, and Power Monitoring: Monitoring granularity goes to the individual outlet — not just the inlet. This matters when you need to prove that a specific device is within its power envelope, track load trends per server, or generate per-tenant power reports in colocation environments.
• 0U Vertical Form Factor: At zero rack units consumed, the VA7U11A0 preserves every U for revenue-generating equipment. Horizontal mounting is supported where needed, but the 0U profile is the real operational advantage in high-density deployments.
• 100–240V / 50–60Hz Input via C14 Coupler: The wide input voltage range (100–240 V) and universal frequency support (50/60 Hz) mean this unit installs identically in North American, European, and Asian data center environments — no regional SKU juggling.
• LED Display for Local Visibility: The onboard LED display gives local technicians an at-a-glance readout without needing network access. Useful during commissioning or when troubleshooting a network outage that takes the management interface offline.
• 3-Meter Cord: The 3 m (approximately 9.8 ft) power cord gives enough slack to reach PDPs or UPS units at the bottom of a standard rack without extension or cable management headaches.
• Comprehensive Protocol Stack: The VA7U11A0 speaks SNMP v1/v2c/v3, HTTPS, SSH, RADIUS, TACACS+, LDAP, Modbus TCP, Syslog, SMTP, NTP, DHCP, IPv4, IPv6, and RSTP. In practice, this means it plugs directly into enterprise DCIM platforms, SNMP-based NMS tools, and SIEM pipelines without middleware shims or protocol converters.
• SNMP v3 and TACACS+ for Enterprise Security: SNMP v3 provides authenticated and encrypted OID polling — a requirement in hardened environments where v1/v2c community strings are explicitly prohibited. TACACS+ enables centralized AAA for technician access, tying PDU logins into the same directory as switches and routers.
• Dual-Stack IPv4/IPv6: Native IPv6 support future-proofs the management interface for operators already running dual-stack or pure IPv6 management networks — no NAT kludges required.
• Single Serial Port + RJ-45 Ethernet + USB: The 1 x serial port supports console-level access or sensor/environmental probe attachment (check Vertiv compatibility list). The single RJ-45 Ethernet port handles all IP management traffic. The USB port supports firmware updates or local configuration without network connectivity.

Integration and Compatibility

The rack PDU management interface supports SNMP v1/v2c/v3 MIBs compatible with major DCIM and NMS platforms. Modbus TCP extends integration to building management systems (BMS) and industrial automation controllers that speak the Modbus register map natively. LDAP and RADIUS integration allow the VA7U11A0 to authenticate operator logins against Active Directory or FreeRADIUS — the same credential store used for the rest of the data center infrastructure. Review the Vertiv rPDU catalog for compatible environmental sensors and accessories that attach via the serial port. For dual-feed architectures, pair this unit with a compatible UPS or power distribution solution to complete the redundancy chain. Operators running DCIM platforms should verify MIB file availability from Vertiv's support portal before deployment.

Frequently Asked Questions

Q: What outlet type does the VA7U11A0 use, and what devices can plug into it?

A: The VA7U11A0 provides six IEC C13 output outlets. Any device with a standard C14 power inlet — including most 1U/2U rack servers, switches, and storage arrays — connects directly. C13 is the most common rack equipment connector in data centers worldwide.

Q: Can individual outlets be switched independently, or only the entire PDU?

A: Each of the six C13 outlets can be switched, power-cycled, or monitored independently via the network management interface. You are not limited to an all-or-nothing PDU-wide switch operation.

Q: What network protocols does the VA7U11A0 support for management?

A: The supported protocol list includes SNMP v1/v2c/v3, HTTP, HTTPS, SSH, LDAP, RADIUS, TACACS+, Modbus TCP, SMTP, NTP, Syslog, DHCP, IPv4, IPv6, and RSTP — covering the full range of enterprise NMS, DCIM, and security integration requirements.

Q: Does the VA7U11A0 require any rack unit space?

A: No. The VA7U11A0 is a 0U device designed for vertical mounting along the rear rail of a rack enclosure, consuming zero rack units of usable equipment space.

Q: What input voltage and frequency ranges are supported?

A: The VA7U11A0 accepts 100–240V AC input at 50 or 60 Hz, making it compatible with power infrastructure in North America, Europe, and Asia without requiring a region-specific model.

Q: Is SNMP v3 supported for encrypted and authenticated polling?

A: Yes. The VA7U11A0 supports SNMP v1, v2c, and v3. SNMP v3 provides authentication and encryption, satisfying requirements in hardened enterprise environments where v1/v2c community strings are not permitted.

Jerry Tildsen

The VA7U11A0 is one of those units I recommend when a customer is trying to consolidate two devices — a separate ATS and a switched PDU — into one vertical slot. The built-in rack transfer switch function combined with per-outlet switching and monitoring across all six C13 outlets is a meaningful reduction in per-rack hardware for single-corded gear in dual-feed racks. The 100–240V wide-input and 3-meter cord make it practical across North American and international data center builds without sourcing region-specific models.

Technical Highlights:

• Per-Outlet Monitoring: Current, voltage, and power tracked at each of the six outlets individually — not just at the PDU inlet. This granularity is the difference between knowing a rack is drawing 8A and knowing which specific outlet is drawing 3A of that 8A.
• SNMP v3 + TACACS+: Both authenticated/encrypted SNMP polling and centralized AAA via TACACS+ are supported natively. No wrapper appliance or proxy needed to meet enterprise security baselines for OOB management access.
• Modbus TCP: Often overlooked on PDUs, Modbus TCP integration means this unit can report directly into BMS or industrial SCADA systems without a protocol gateway — relevant in colocation facilities or hybrid IT/OT environments.

Deployment Considerations:

• The C14 coupler input means you need a C13-to-C14 whip or a C14-terminated UPS/ePDU output — verify your upstream power source has matching C14 outlet availability before ordering, especially in retrofits where C19/C20 or NEMA L6-20 dominate.
• With only six outlets, this unit is best suited for small-footprint racks or targeted critical-device rows. High-density deployments with 20+ devices per rack will need a higher-outlet-count model in the Vertiv rPDU line.

The VA7U11A0 is best positioned for edge data closets, branch server rooms, and colocation cage deployments where you need ATS functionality, remote outlet switching, and full DCIM-compatible monitoring without dedicating 1U or more to power management hardware.
