Server Technology C2S42CE-YCMFAM00/C Smart PRO2 42-Outlet Rack PDU

Overview

The Server Technology C2S42CE-YCMFAM00/C is a Smart PRO2-series rack power distribution unit built around a 45-outlet configuration: 42 x AC power outlets plus 3 x NEMA 5-20R receptacles, fed by a 30A input through a NEMA L21-30P plug on 208V service. This is a high-density outlet count aimed at server racks and network closets where a single PDU needs to power dozens of discrete devices without daisy-chaining multiple strips. C2S42CE-YCMFAM00/C is classified by the manufacturer as a PDU in the Smart Product Series PRO2 line, and it's built to sit in the power layer behind your compute, storage, and networking gear rather than as a customer-facing device — but the outlet math still has to work for your rack before you buy it.

Key Features

• 42 x AC Power Outlets: a high outlet density means one PDU can cover a fully populated rack of switches, servers, and small appliances without splitting the load across two or three units — fewer PDUs to mount, wire, and track in your power documentation.
• 3 x NEMA 5-20R Receptacles: standard 5-20R outlets on the same chassis give you drop-in compatibility for standard NEMA 5-15/5-20 plugs on peripheral gear (KVMs, monitors, laptops) without needing a separate adapter strip mounted elsewhere in the rack.
• 30A Input Current: a 30A circuit gives real headroom for a densely populated rack pulling steady load across 42 outlets — undersizing input current on a high-outlet-count PDU is a common way to trip a breaker at the worst possible time, so this rating matters when you're planning circuit assignments.
• NEMA L21-30P Plug/Connector: a locking twist-lock plug rated for 30A keeps the PDU seated under vibration or accidental cable snags — standard on 208V three-phase and split-phase distribution in data center and telecom environments, so confirm your upstream receptacle matches before ordering.
• 208V Operation: running at 208V rather than 120V lets the same current rating deliver more usable wattage to the rack, which is why 208V PDUs are the default in most commercial server rooms and colocation cages rather than a 120V equivalent.
• Smart PRO2 Product Family: Server Technology's PRO2 line is positioned as its core managed/monitored PDU family — worth confirming metering and network-management options with the specific SKU configuration before you standardize a rack design around it.

Integration & Compatibility

Because the C2S42CE-YCMFAM00/C terminates in a NEMA L21-30P locking plug, it's built for facilities already wired with L21-30 receptacles or whip circuits at 208V — check your existing PDU whips or panel schedule before ordering rather than assuming compatibility with a standard 120V duplex outlet. The mixed outlet configuration (42 AC power outlets plus 3 NEMA 5-20R) means it can feed both bulk rack-mount equipment and a handful of standard-plug peripherals from one chassis, which simplifies cable management in racks that would otherwise need a secondary small-format strip. If you're standardizing rack power across a data hall, this model is worth evaluating alongside Server Technology's broader power and rack equipment line and the rest of the Server Technology catalog to confirm outlet count and input current against your actual rack load before committing to a SKU. For planning circuit assignments and headroom across a row of racks, a power and PoE planning guide is useful background before finalizing your PDU order, and pairing this PDU with properly rated rack-mount enclosures keeps cable runs clean once it's installed.

Frequently Asked Questions

Q: What input current does the C2S42CE-YCMFAM00/C require?

A: It's rated for 30A input at 208V, delivered through a NEMA L21-30P locking plug.

Q: How many outlets does the C2S42CE-YCMFAM00/C have?

A: It has 42 AC power outlets plus 3 NEMA 5-20R receptacles, for a total of 45 outlets on one chassis.

Q: What plug type does this PDU use to connect to building power?

A: A NEMA L21-30P twist-lock plug, which requires a matching L21-30 receptacle or whip on your 208V circuit.

Q: Is the C2S42CE-YCMFAM00/C part of a specific Server Technology product line?

A: Yes, it's part of the Smart Product Series PRO2 line from Server Technology.

Q: Can I plug standard NEMA 5-15 or 5-20 devices into this PDU?

A: Yes, the 3 onboard NEMA 5-20R receptacles accept standard 5-15P and 5-20P plugs directly.

The C2S42CE-YCMFAM00/C is one of the higher outlet-density PDUs I spec for full-height racks — 42 AC outlets plus 3 NEMA 5-20R on a single 30A/208V feed covers most fully loaded server or network racks without needing a second strip.

Technical Highlights:

• 30A Input at 208V: gives enough headroom to run 42 outlets under real load without tripping the upstream breaker — undersizing the feed circuit is the most common mistake I see on high-density PDU installs.
• NEMA L21-30P Locking Plug: the twist-lock design won't walk out of the receptacle from cable strain or vibration, which matters in racks with dense cable management in front of the PDU.
• Mixed Outlet Configuration (42 AC + 3 NEMA 5-20R): the 5-20R outlets let you plug in a KVM console or laptop directly without hunting for an adapter, while the 42-outlet bank handles the bulk rack-mount load.

Deployment Considerations:

• Confirm your rack's whip or receptacle is already terminated for NEMA L21-30 before ordering — this is a locking twist-lock connector, not a standard duplex plug, so it won't work on a generic 120V circuit.
• At 45 total outlets on one 30A circuit, plan your load distribution carefully across the bank rather than clustering high-draw devices on one side of the PDU.

This is the right call for a data closet or colocation cage standardizing on 208V, high-density rack power where you want one PDU per rack instead of stacking multiple lower-outlet-count strips.
