Server Technology C3W36RL-DCJE2MT3 0U Switched PDU

Overview

The Server Technology C3W36RL-DCJE2MT3 is a 0U Switched PRO3X rack PDU built for data center and network operations centers that need per-outlet control and metering across a dense 36-outlet load. It runs on a 208V input at 50/60 Hz through a NEMA L15-30P plug rated 30A (24A continuous), delivering 8.6kW of usable input power capacity. The mixed outlet bank — 18 C13 receptacles and 18 HDOT Cx outlets — covers both standard IEC power cords and Server Technology's locking High Density Outlet Technology connectors, so a single strip can serve a rack of mixed server and switch gear without adapter cables working loose during maintenance.

Key Features

• 36 RamLock HDOT Outlets (18 C13 + 18 Cx): HDOT Cx receptacles physically lock standard C14/C20 cords in place, which matters on a fully populated 0U strip where vibration or accidental cord tugs during rack service can otherwise knock a server offline.
• 8.6kW Input Power Capacity at 208V: With a 30A NEMA L15-30P input plug and 24A rated continuous draw, the C3W36RL-DCJE2MT3 covers a mid-to-high density rack without tripping into overload territory — check your actual server nameplate load against the 24A continuous rating before populating all 36 outlets.
• Per-Outlet Switching and Metering: As a Switched model, individual outlets can be power-cycled remotely — useful for rebooting a hung server or network appliance without a site visit, and for staggering inrush current on a cold-start of the whole rack.
• Three 2-Pole 20A Branch Circuit Breakers, 10kAIC: Splitting the 36-outlet load across three independently protected branches means a single overloaded branch trips its own breaker instead of dropping the entire PDU, and the 10kAIC interrupt rating gives the breakers headroom against short-circuit fault currents in a data center environment.
• Gigabit Ethernet Management (10/100/1000 Mbps): Full-speed network management keeps the PDU responsive on management VLANs handling SNMP polling, syslog, and web UI sessions from monitoring platforms without becoming a bottleneck.
• HTTP(S), SSH, Telnet, SNMP, FTP/SFTP, SMTP, Syslog, LDAP(S), RS-232: This protocol set lets the PDU slot into existing data center management stacks — LDAP(S) for centralized authentication, SNMP and Syslog for monitoring integration, and RS-232 console access for out-of-band configuration when the network path is down.
• 2 Sensor Ports, 1 Aux Port: Environmental sensor inputs (temperature/humidity probes) let a single PDU report rack-level conditions alongside power data, consolidating monitoring hardware in the cabinet.
• 2 USB Ports and 1 Console Port: Local USB and serial console access covers initial commissioning and firmware recovery scenarios where network access isn't yet configured.
• Unloaded Power Draw Under 10W: The PDU's own management electronics sip under 10W, so its overhead barely registers against the 8.6kW capacity budget you're allocating to actual IT load.
• 0U Vertical Form Factor, 70.0in x 2.2in x 2.5in: The 0U profile mounts in the rear channel of the rack rather than consuming horizontal U-space, preserving every rack unit for servers, switches, and storage.
• Operating Range 0°C to 60°C, 8-90% RH Non-Condensing: The extended thermal range supports deployment in hot-aisle-adjacent PDU mounting positions or less climate-controlled network closets, not just tightly conditioned data halls.

Integration & Compatibility

The C3W36RL-DCJE2MT3 (often searched as C3W36RL DCJE2MT3) is built to slot into standard rack power management workflows. Its SNMP and HTTP(S) management interfaces integrate with common data center infrastructure management (DCIM) platforms, and LDAP(S) support lets IT teams tie outlet-level access control into existing directory services rather than maintaining a separate local user database. The RS-232 console and USB ports give administrators an out-of-band path for firmware updates and configuration recovery independent of the production network — a detail worth planning around policies covered in a broader power and PoE planning guide when this PDU sits in a rack alongside PoE switches feeding IP cameras. For sites building out full power redundancy, pairing this switched PDU with a second unit on an independent circuit is a common configuration; browse the broader power distribution category for compatible redundant PDU options. This unit carries UL 62368-1, CSA C22.2 No. 62368-1, FCC Part 15 Class A, and CAN ICES-003 Class A certification, relevant for data centers with formal equipment compliance requirements.

Frequently Asked Questions

Q: What input plug does the C3W36RL-DCJE2MT3 use?

A: It terminates in a NEMA L15-30P plug rated for 30A at 208V, with a 24A continuous input current rating.

Q: How many outlets does the C3W36RL-DCJE2MT3 have and what type?

A: 36 total outlets: 18 C13 receptacles rated up to 12A each at 208V L-L (15A peak), and 18 HDOT Cx locking outlets rated up to 16A each at 208V L-L (20A peak).

Q: Is the C3W36RL-DCJE2MT3 a switched PDU?

A: Yes, this is a Switched PRO3X model, meaning individual outlets can be controlled and power-cycled remotely rather than only monitored.

Q: What is the warranty on the C3W36RL-DCJE2MT3?

A: It carries a 2-year limited manufacturer warranty.

Q: What network protocols does the C3W36RL-DCJE2MT3 support for remote management?

A: HTTP(S), SSH, Telnet, SNMP, FTP/SFTP, SMTP, Syslog, LDAP(S), and RS-232 console access, over a 10/100/1000 Mbps Ethernet port.

Q: What operating temperature range is the C3W36RL-DCJE2MT3 rated for?

A: 0°C to 60°C with 8%RH to 90%RH non-condensing humidity, and it stores between -30°C and 80°C.

I spec a lot of 0U vertical PDUs for cabinet builds, and the thing that stands out on the C3W36RL-DCJE2MT3 is the 18 HDOT Cx outlet count on top of the 18 standard C13s — that's a deliberate design for racks mixing legacy IEC power cords with gear that benefits from a locking connection. At 8.6kW capacity on a 24A continuous / 30A input through the NEMA L15-30P, this is sized for a real mid-density rack, not a token power strip.

Technical Highlights:

• Three 20A branch circuit breakers, 10kAIC: Splitting 36 outlets across three independently protected 2-pole branches means one overloaded blade server doesn't take down every outlet on the strip — and 10kAIC gives real fault-current margin in a data center electrical environment.
• Per-outlet switching: Being a Switched (not just Metered) PRO3X model, you get remote power-cycling per outlet — I use this constantly for hung iLO/iDRAC-less devices where a truck roll would otherwise be the only fix.
• Sub-10W unloaded draw: The PDU's own overhead barely dents your 8.6kW budget, so nearly all of your capacity planning maps directly to actual IT load.

Deployment Considerations:

• Check your rack's actual continuous load against the 24A rating before populating all 36 outlets — the C13 outlets cap at 12A each and the Cx outlets at 16A each, but the branch breakers and the 24A input rating are the real ceiling.
• The 70-inch vertical length needs a full-height 0U rear channel; confirm cabinet depth and rear rail clearance before ordering, especially in shallower network cabinets versus full-depth server racks.

This is the right call for a data center or NOC rack running mixed C13 and locking-connector gear where remote outlet cycling and per-branch circuit protection both matter — think colo cage builds or remote network closets where a truck roll to power-cycle a hung device isn't an option. The C3W36RL-DCJE2MT3's 8.6kW capacity fits a moderate-density server or network rack rather than a full high-density GPU compute cabinet.
