Vertiv Rpdu Rack Transfer Switch Switched Outlet Level Monitoring 30A 208V 4.9KW H - VA7N31A0

Vertiv VA7N31A0 Switched Monitored Rack PDU 30A 208V Horizontal

Overview

The Vertiv VA7N31A0 is a 0U horizontal rack PDU designed for data center and server room deployments where both per-outlet switching control and real-time power monitoring belong on the same unit. Running at 30A/208V with a 4.9kW capacity, the VA7N31A0 fits directly into 19-inch rack infrastructure via a NEMA L6-30P plug — the standard input on 208V PDU circuits in enterprise and colocation environments. If you're managing mixed C13/C19 device populations and need remote reboot, load visibility, and multi-protocol integration in a single horizontal form factor, this is the model to evaluate.

The rack power distribution segment is crowded, but the VA7N31A0 earns consideration specifically for deployments where outlet-level switching is non-negotiable — think remote hands replacement in colo, or staged power sequencing for dense compute rows. The horizontal 0U mounting keeps all rack-unit space available for revenue-generating hardware.

Key Features

• 30A / 208V / 4.9kW Input via NEMA L6-30P: Matches the most common 208V single-phase breaker allocation in enterprise data centers. At 4.9kW, you can fully populate the six outlets without flirting with the 80% continuous-load rule — just stay under 24A aggregate to stay code-compliant. No derating gymnastics required on a properly provisioned 30A circuit.
• Six Switched Outlets (C13 + C19 Mix): Both C13 (standard 1U/2U server IEC) and C19 (higher-draw PDUs, GPU servers, large UPS loads) outlet types are available. Per-outlet switching means you can remotely cycle a hung server without touching adjacent gear — critical when physical access means a datacenter ticket and a 4-hour SLA.
• Current, Voltage, and Power Monitoring: Real-time metering at the input level lets you trend load over time and catch a circuit creeping toward its limit before it trips. Pair this with SNMP traps and you get proactive alerting rather than reactive firefighting when a rack fills up unexpectedly.
• LCD Display: Local readout means technicians walking the floor can read current draw without logging into a management interface. Useful during commissioning, audits, and any time the network itself is the thing that's broken.
• SNMP v1/v2c/v3 + Full Protocol Stack: SNMP v3 provides authenticated, encrypted polling — the baseline requirement for most enterprise NOC environments. The protocol list also covers HTTPS, SSH, RADIUS, TACACS+, LDAP, and Modbus TCP. That last one matters if you're integrating PDU data into a BMS or DCIM platform that speaks Modbus rather than SNMP.
• IPv4/IPv6 Dual-Stack with DHCP/NTP/Syslog: Native IPv6 support future-proofs the management plane as enterprise networks continue transitioning. Syslog integration routes power events into your existing log aggregation infrastructure — no separate DCIM required for event correlation.
• Single RJ-45 Management Port + USB + Serial: The RJ-45 Ethernet port handles all IP-based management. The USB and serial ports provide out-of-band access options — serial console is particularly useful for initial provisioning or recovery when the network path is unavailable.
• 3-Meter Power Cord: The 3m cord gives enough reach to connect to a PDU whip or panel without requiring an extension — standard for most mid-depth and full-depth rack layouts. Verify your cabinet's PDU-to-panel distance before assuming sufficiency in very deep or remote-mounted configurations.
• 50/60 Hz Input, 200–240V Range: Accepts both North American 60Hz and international 50Hz supply frequencies. The 200–240V voltage window accommodates regional variation in nominal 208V or 230V feeds without manual reconfiguration.
• Horizontal 0U Mounting: Mounts at the top or bottom of the rack without consuming rack units. In fully populated 42U or 48U cabinets, this matters — every 1U saved is another switch, server, or patch panel you can deploy.

Integration and Compatibility

The VA7N31A0 integrates with Vertiv's broader power management ecosystem and is accessible via standard SNMP MIBs for third-party DCIM tools including platforms from Schneider, Nlyte, and similar. RADIUS and TACACS+ support means PDU authentication plugs into your existing AAA infrastructure rather than requiring local credential management per device. Modbus TCP opens a path to building automation systems that already poll environmental and power data from non-IT equipment. For network infrastructure racks where per-outlet control is needed alongside standard monitoring, this PDU operates without proprietary agents on the managed servers — SNMP polling requires only a management VLAN and appropriate community strings or v3 credentials.

Frequently Asked Questions

Q: What input plug does the VA7N31A0 use, and what circuit does it require?

A: The VA7N31A0 uses a NEMA L6-30P input plug and requires a dedicated 30A, 208V single-phase circuit. For continuous loads, plan to keep aggregate draw at or below 24A (80% of rated capacity) to comply with NEC and most facility electrical standards.

Q: Does the VA7N31A0 support SNMP v3 with encryption?

A: Yes. The VA7N31A0 supports SNMP v1, v2c, and v3. SNMP v3 provides authentication and encryption, meeting the baseline security requirement for most enterprise NOC and DCIM integrations.

Q: Can I control each outlet independently, or is it all-or-nothing switching?

A: The VA7N31A0 provides switched outlet-level control across all six outlets. Each outlet can be switched on, off, or power-cycled independently via the management interface — critical for remote server reboots without affecting adjacent devices.

Q: What outlet types are on the VA7N31A0?

A: The VA7N31A0 provides a mix of C13 and C19 IEC outlets. C13 handles standard 1U/2U server power cords; C19 accommodates higher-draw devices such as GPU servers, large UPS units, or high-density PDUs. Check your device power cord types before deploying.

Q: Does the VA7N31A0 work with Modbus TCP for BMS or DCIM integration?

A: Yes. Modbus TCP is listed among the supported network protocols, making the VA7N31A0 compatible with building management systems and DCIM platforms that use Modbus as their primary polling protocol alongside or instead of SNMP.

Q: Is the VA7N31A0 compatible with both 50Hz and 60Hz power supplies?

A: Yes. The unit accepts 50/60 Hz input across a 200–240V voltage range, making it suitable for both North American (208V/60Hz) and international (230V/50Hz) data center environments without reconfiguration.

James Everett

The detail that stood out to me on the VA7N31A0 is the Modbus TCP support alongside SNMP v3 — that combination is still uncommon enough in rack PDUs at this price point that it's worth calling out explicitly. In facilities where a BMS is already polling HVAC and environmental sensors via Modbus, being able to include PDU load data in the same polling loop without a separate gateway is a real integration win. The 30A/208V input via NEMA L6-30P puts this squarely in the enterprise single-phase tier, and the horizontal 0U form factor means it won't cost you a rack unit in a densely populated cabinet.

Technical Highlights:

• Per-Outlet Switching (6 Outlets): Independent C13 and C19 outlet control enables remote power cycling of individual servers — eliminates truck rolls for hung-device reboots in colo or remote edge deployments.
• SNMP v3 + TACACS+/RADIUS: Authenticated, encrypted SNMP polling plus AAA integration means PDU credentials are managed by your existing identity infrastructure, not a local password list on each unit.
• Modbus TCP Protocol Support: Allows direct integration with DCIM and BMS platforms that use Modbus as the native polling protocol — a significant deployment advantage in mixed-infrastructure facilities.

Deployment Considerations:

• The 3-meter cord is adequate for most standard-depth racks connecting to a nearby PDU whip, but verify actual panel-to-rack distance in your specific cabinet layout before assuming it reaches without an extension.
• With six outlets total across a 30A feed, you're capacity-constrained relative to higher-outlet-count PDUs — this unit fits best in focused deployments (a single compute row or a few high-draw devices) rather than serving as a shared-rack PDU for diverse mixed loads.

This PDU is the right fit for a colocation or enterprise edge cabinet where remote outlet-level control, SNMP v3 compliance, and BMS integration via Modbus TCP are all required in a horizontal mount — not a general-purpose PDU for every rack in the building, but a strong match for racks where those specific capabilities are non-negotiable.
