Server Technology C2S42CE-YQME2M00 42-Outlet 3-Phase Smart PDU

Overview

The Server Technology C2S42CE-YQME2M00 is a PRO2 HDOT Smart PDU built for data center racks that need dense outlet counts without giving up per-inlet visibility. It's a 208V 3-phase Wye unit rated for 17.3kW input capacity, delivering power through 42 IEC 60320/C13 outlets in a slim 2.2in wide, 2.5in deep, 70in tall vertical rack-mount chassis. If you're standardizing a cabinet fleet on 3-phase, high-density PDUs with network-based monitoring, the C2S42CE-YQME2M00 covers a full rack's worth of C13-terminated server and switch gear off a single 60A IEC 60309 3P+N+G feed.

Key Features

• 17.3kW Input Power Capacity at 208V: A 60A input (48A rated continuous) on a 208V Wye 3P+N+G IEC 60309 plug gives a single PDU enough headroom for a fully loaded compute or switch rack, cutting the number of circuits an electrician has to run to the cabinet.
• 42 x IEC 60320/C13 Outlets via HDOT: High Density Outlet Technology packs 42 outlets into a 2.2in-wide rail — the point of this spec is fitting more servers and PDUs-worth of cordage per rack unit without outlets that back out under cable weight, since HDOT outlets carry higher native retention and a UL94V-0 flame rating.
• Alternating-Phase Outlet Layout: Outlets alternate phases down the rail, so load balancing across the three phases doesn't require hunting for the right receptacle or running longer power cords across the rack — shorter cords also mean better airflow behind the gear.
• Per-Inlet Power Sensing (PIPS): Each inlet reports current (A), voltage (V), watts, VA, crest factor, power factor, and energy — the data you need to right-size UPS and generator capacity instead of guessing at nameplate ratings.
• Branch Circuit Protection, UL489 2-Pole Breakers: Six branch circuits are each protected by UL489-compliant 20A-trip, 10kAIC breakers rated to 16A continuous, so a single overloaded branch trips locally instead of taking down the whole PDU.
• Branch Current Monitoring with SNMP Alerts: Current is tracked at each breaker branch with SNMP-based alerts before a branch trips — useful for catching a slow creep toward an overload before it becomes a 2 a.m. outage call.
• Hot-Swap Network Card with Star Multi-Linking: Up to four power circuits link under one IP address, and if the primary unit loses power, the linked expansion unit keeps the network card alive — you don't lose remote visibility into the rest of the row just because one PDU dropped input power.
• Auto-Flip Current Display: An onboard LED display cycles per-phase current readings at the rack, so a tech doing manual load balancing doesn't need a laptop or browser session open just to see if a phase is close to its limit.
• Temperature/Humidity Monitoring, 2 x 4P4C Probe Inputs: Two 10ft external T/H probe inputs feed SNMP alerts and email notifications, giving you environmental monitoring for the cabinet without a separate sensor appliance.
• Wide Operating Envelope: Rated 0°C to 60°C at 8%RH to 90%RH non-condensing up to 6,500ft elevation — this PDU tolerates hot-aisle exhaust temperatures and higher-elevation data centers without derating concerns typical of consumer-grade power strips.
• Measurement Accuracy — Input +/-1%, Branch +/-3%: Input current, voltage, and power are measured to +/-1% (0.01A/0.1V/1W resolution); branch current to +/-3% (0.01A resolution) — accurate enough to trust for capacity planning and billback in colocation environments.

Integration & Compatibility

Network connectivity runs over 10/100/1000 Mbps Ethernet (RJ-45) plus an RS-232 serial RJ-45 port, with an RJ-12 link port for daisy-chaining linked units under Star Multi-Linking. Protocol support spans HTTP(S), SSH, Telnet, SNMP, (S)FTP, SMTP, Syslog, LDAP(S), and RS-232 — enough to fold the C2S42CE-YQME2M00 into an existing DCIM stack or SNMP monitoring pipeline without a proprietary management layer. It carries UL 62368-1, CSA C22.2 No. 62368-1, FCC Part 15 Class A, and CAN ICES-003 Class A certification. The C2S42CE-YQME2M00 (often searched as C2S42CE YQME2M00) fits into a broader rack power strategy alongside network video recorders and other continuously-powered rack gear where per-branch monitoring and alternating-phase load balancing matter as much as raw outlet count. For guidance on sizing PDU capacity against actual rack load, see the PoE and power planning guide. Pair it with rack mounting accessories when configuring a new cabinet, and review the full Server Technology PDU catalog for lower-outlet-count or single-phase variants. Buyers standardizing an entire row should also look at the power distribution units category for compatible linked expansion models.

Frequently Asked Questions

Q: How many outlets does the C2S42CE-YQME2M00 have?

A: 42 IEC 60320/C13 outlets, each rated <= 12A @ 208V L-L (15A peak), arranged in an alternating-phase HDOT layout.

Q: What input power does the C2S42CE-YQME2M00 require?

A: A 208V Wye 3-phase feed via a 60A IEC 60309 3P+N+G plug, rated 48A continuous with 17.3kW total input capacity.

Q: Does the C2S42CE-YQME2M00 support remote monitoring?

A: Yes. It connects over 10/100/1000 Mbps Ethernet and RS-232 serial and supports HTTP(S), SSH, Telnet, SNMP, (S)FTP, SMTP, Syslog, and LDAP(S) for remote power and environmental monitoring.

Q: Can the C2S42CE-YQME2M00 monitor temperature and humidity?

A: Yes, it has two 4P4C inputs for external temperature/humidity probes with SNMP-based alerting and email notifications.

Q: What happens if the primary unit loses power in a linked configuration?

A: With Star Multi-Linking, the hot-swap network card stays powered by the linked expansion unit, so network access and monitoring continue even if the primary unit loses input power.

Q: What is the branch circuit protection on this PDU?

A: Six branch circuits, each protected by UL489-compliant 2-pole, 20A-trip circuit breakers rated <= 16A with 10kAIC interrupt capacity.

The C2S42CE-YQME2M00 is one of the denser PRO2 PDUs I spec for 3-phase cabinets — 42 C13 outlets off a single 60A/208V Wye feed is a lot of terminated gear on one PDU, and the per-inlet metering means you're not flying blind on any of it.

Technical Highlights:

• Per-Inlet Power Sensing (PIPS): current, voltage, power, VA, crest factor, power factor and energy per inlet, measured to +/-1% on current/voltage/power — accurate enough for real capacity planning, not just an alarm trigger.
• 60A Input, 17.3kW Capacity: the 48A-rated continuous draw on a 208V 3P+N+G feed means you're sizing upstream breakers and UPS output around a real number, not a nameplate guess.
• Six UL489 Branch Breakers at 16A/10kAIC: branch-level protection with SNMP alerting on current means a single overloaded branch trips locally and alerts before it takes the rack down.

Deployment Considerations:

• This is a 70in tall, 2.2in wide vertical PDU — confirm 0U rack rail clearance before ordering, especially in cabinets already running cable managers on both sides.
• Outlets are C13-only at <= 12A each — anything drawing a C19-class load needs a different PRO2 configuration, so check your PDU/server inlet types before standardizing an entire row on this SKU.

This is the PDU I reach for on a 3-phase colocation cabinet build where the customer wants full per-branch visibility and SNMP alerting wired into their DCIM before the rack ever goes live, not retrofitted after the first overload trip.
