APC by Schneider Electric SMT2200R2X658 2200VA 2U Rack-Mount UPS
Overview
The APC by Schneider Electric SMT2200R2X658 is a 2200VA rack-mount uninterruptible power supply built for servers, network infrastructure, storage devices, and business-critical electronics. Occupying 2U of rack space in a 18.9 x 3.4 x 26.9 inch chassis, it fits standard 19-inch equipment racks without consuming disproportionate rack real estate — a practical consideration when rack density is already a constraint.
Input is via a NEMA 5-20P connector at 120 VAC, which means the circuit requirements are straightforward for most North American commercial installations: a dedicated 20A branch circuit handles this unit without special wiring. The lead-acid battery chemistry is field-proven for this class of UPS — replacement batteries are widely available, and the battery swap process on the Smart-UPS platform is designed to be tool-free and hot-swappable in most configurations, which matters when uptime is non-negotiable.
Key Features
- 2U Rack Form Factor: At 3.4 inches tall, the SMT2200R2X658 fits standard 2U rack slots. The 26.9-inch depth fits most mid-depth and full-depth equipment racks — verify your rack's usable depth before ordering, as shallow-depth racks under 24 inches will not accommodate this unit.
- NEMA 5-20P Input: The 20-amp plug requires a dedicated 20A/120V circuit. If your rack PDU or wall outlet is only 15A (NEMA 5-15), you will need a circuit upgrade or adapter — plan this during pre-installation.
- 120 VAC Input Voltage: Designed for standard North American single-phase power. This is not a 208V or international unit — confirm your facility power before specifying.
- Lead-Acid Battery Technology: Sealed lead-acid batteries offer predictable runtime behavior and a mature replacement ecosystem. Runtime figures of approximately 5 minutes at full load and approximately 15 minutes at reduced load give enough bridge time for graceful shutdowns or generator transfer in most data closet and IDF deployments.
- Broad Device Compatibility: Rated for servers, network gear, storage arrays, and general business electronics — covers the typical mixed load in an IDF or small server room without requiring separate UPS units per device class.
Installation Notes
The SMT2200R2X658 ships in a 2U rack-mount form factor. Plan for a dedicated 20A branch circuit at 120 VAC with a NEMA 5-20 receptacle at the rack location. Total chassis depth of 26.9 inches requires verification against your rack's internal usable depth. For UPS and power protection deployments in surveillance or network closets, pair with a managed PoE switch on the protected output to maintain camera uptime during outages.

Frequently Asked Questions
Q: What input plug does the SMT2200R2X658 use?
A: The SMT2200R2X658 uses a NEMA 5-20P input connector, requiring a dedicated 20-amp, 120V branch circuit.
Q: What is the rack space requirement for the SMT2200R2X658?
A: The unit occupies 2U of rack space and measures 18.9 x 3.4 x 26.9 inches (W x H x D). Confirm your rack has at least 26.9 inches of usable internal depth before installation.
Q: What is the approximate runtime of the SMT2200R2X658?
A: Based on available evidence, runtime is approximately 5 minutes at full load and approximately 15 minutes at a reduced load. Actual runtime depends on the connected load — lighter loads extend runtime proportionally.
Q: What battery type does the SMT2200R2X658 use?
A: It uses sealed lead-acid batteries, a field-proven chemistry with a wide replacement battery ecosystem. Replacement batteries for the Smart-UPS platform are widely available.
Q: Is the SMT2200R2X658 suitable for 208V or international installations?
A: No. This unit is rated for 120 VAC input and is designed for standard North American single-phase circuits. It is not appropriate for 208V, 240V, or international voltage environments.
The SMT2200R2X658 is a 2U rack-mount UPS that fits squarely in the IDF closet and small server room segment — the 26.9-inch chassis depth and NEMA 5-20P input are the two specs I look at first when specifying this unit, because a rack that's too shallow or a circuit that's only 15A will stop an installation cold before a single device is protected.
Technical Highlights:
- 2U / 18.9 x 3.4 x 26.9 in. chassis: Fits standard 19-inch racks but demands 26.9 inches of usable internal depth — measure your rack before ordering, not after.
- NEMA 5-20P input at 120 VAC: Requires a dedicated 20A branch circuit. This is a hard electrical requirement, not a recommendation — a 15A circuit will not support this unit.
- Dual runtime figures (5.10 min full load / 15.20 min reduced load): That 15-minute window at partial load is enough for an automated graceful shutdown sequence on most small server environments or a generator transfer in a surveillance head-end closet.
Deployment Considerations:
- Verify rack usable depth before procurement — 26.9 inches is longer than many wall-mount and shallow-depth open-frame racks. A site measurement takes two minutes; a wrong-depth return does not.
- The NEMA 5-20P plug is non-negotiable — if the nearest circuit is a standard NEMA 5-15 (15A) outlet, a circuit upgrade or a 20A PDU with appropriate feed is required before this unit can be installed safely.
This unit is well-positioned for IDF closets and surveillance head-end rooms running mixed loads of PoE switches, NVRs, and access control panels on a single 120V feed — where a 2U footprint and a predictable 15-minute bridge at partial load cover the shutdown and transfer window without over-engineering the power infrastructure.
