Server Technology C4W36RA-ENBE2FE2 Switched Rack PDU with Outlet-Level Control

The C4W36RA-ENBE2FE2 is a 3.6kW switched rack PDU built for data center cabinets that need remote outlet control without guessing at circuit loading. It runs on a 230V, 16A IEC 60309 2P+PE 6-hour input plug and spreads that capacity across 36 total outlets — 12 C13 and 24 Cx — so a single vertical unit can feed a mixed rack of servers, switches, and storage nodes without a second PDU or a scramble for adapters. This is a zero-U vertical form factor at 1778mm x 56mm x 64mm, sized to mount in the rear channel of a standard rack without eating into usable U space.

Overview

This unit belongs to Server Technology's switched PDU line, positioned for environments where remote reboot capability and per-outlet visibility matter more than raw outlet count alone. The C4W36RA-ENBE2FE2 pairs a hot-swappable controller with per-inlet power sensing, so the electrical intelligence of the unit is separated from the outlet bar itself — a design detail that affects how you plan maintenance windows, covered below.

Key Features

• HDOT Cx Outlets (24x): Each Cx outlet is a UL-tested hybrid accepting both C14 and C20 plugs, so you're not stuck ordering the wrong PDU because a server ships with a C20 cord instead of C14 — one outlet type handles both without an adapter.
• 12x C13 Outlets rated <= 10A @ 230V L-N: Standard C13 landing points for switches, KVMs, and lower-draw devices, keeping your higher-current Cx outlets free for servers that actually need them.
• 45-Degree Angled Infeed: The angled infeed reduces bend radius pressure on the 60A-rated input cord and improves rear-of-rack accessibility — a real factor when you're working in a 4-inch cable channel with three other PDUs already mounted.
• Per-Inlet Power Sensing (PIPS): Monitors current (A), voltage (V), watts, apparent power (VA), crest factor, power factor, and energy at the inlet, with input measurement accuracy of +/-0.2% on both voltage and current — tight enough to trust for capacity planning instead of estimating headroom.
• Branch Circuit Protection: UL489-compliant 2-pole, 20A trip circuit breakers rated at 10kAIC interrupt capacity, meeting UL and IEC 62368-1 branch circuit protection requirements — this is what keeps a single outlet fault from taking down the whole PDU.
• Network Monitoring: HTTP(S), SSH, Telnet, SNMP, (S)FTP, SMTP, Syslog, LDAP(S), and RS-232 serial access, all over a 10/100/1000 Mbps Ethernet interface — fast enough to pull waveform captures or bulk SNMP polling without the PDU's network stack becoming the bottleneck.
• Multi-Unit Linking & Cascading: Daisy-chain up to 16 PDUs from a single primary unit over one IP address, cutting the number of management IPs and switch ports you need to provision per rack row.
• Hot-Swappable Controller: The controller houses the compute, display, and connectivity for the PDU and can be replaced without de-energizing the outlet bar — meaning a controller fault doesn't force a load-shedding outage to fix.
• Power Quality Measurements & Waveform Capture: Tracks harmonics, voltage dips/swells, and crest factor, with automatic or on-demand waveform capture — useful for diagnosing intermittent load issues before they become a support ticket to the utility or generator vendor.
• Environmental Monitoring: Supports up to 12 daisy-chained DX2-series SmartSensors with SNMP alerting and email notifications, letting you extend monitoring to rack-level temperature and humidity from the same management plane as the PDU.
• Multi-Color LCD & RGB Outlet LEDs: Local LCD shows power usage, alerts, and alarms at the rack, while per-outlet RGB LEDs flag on/off state and threshold or measurement irregularities — a technician standing at the rack doesn't need a laptop to see which outlet tripped.
• Operating Range 0°C to 60°C, 5-90% RH non-condensing: Covers standard data center halls as well as warmer edge or colocation spaces run at higher intake temperatures for efficiency.

Integration & Compatibility

The C4W36RA-ENBE2FE2 (often searched as C4W36RA ENBE2FE2) reports over SNMP and standard serial/network protocols, so it integrates with existing DCIM platforms rather than requiring a proprietary management console. If you're standardizing PDU management across a row or a whole hall, review these units alongside other power distribution units in the same switched-PDU family to keep firmware and outlet configuration consistent across racks. Pair it with rack-mount options from the broader Server Technology catalog when specifying a new cabinet build, and consult a power and PoE planning guide before finalizing branch circuit sizing across multiple PDUs on the same panel. For racks running IP video or access control gear off the same power plan, cross-reference against your network video recorder power budget so the PDU's 3.6kW input capacity isn't oversubscribed. Complementary rack accessories such as cable management arms are worth specifying alongside a vertical zero-U unit of this length.

Frequently Asked Questions

Q: What input plug does the C4W36RA-ENBE2FE2 use?

A: It uses an IEC 230V/16A 2P+PE 6-hour plug, rated for 16A input current and 3.6kW input power capacity.

Q: How many outlets does the C4W36RA-ENBE2FE2 have?

A: It has 36 total outlets: 12 C13 outlets rated <= 10A @ 230V L-N and 24 HDOT Cx outlets rated <= 16A @ 230V L-N.

Q: Can I daisy-chain multiple C4W36RA-ENBE2FE2 units together?

A: Yes. Up to 16 PDUs can be linked and cascaded from a single primary unit over one IP address via USB or Ethernet.

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

A: UL489-compliant 2-pole, 20A trip circuit breakers with a 10kAIC interrupt rating.

Q: What network protocols does the C4W36RA-ENBE2FE2 support for monitoring?

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

Q: What operating temperature range is the unit rated for?

A: 0°C to 60°C with 5% to 90% RH non-condensing humidity.

James Everett

What stands out on the C4W36RA-ENBE2FE2 is the outlet mix — 12 C13 plus 24 HDOT Cx on a single 230V/16A infeed. That Cx outlet accepting both C14 and C20 plugs solves a real ordering headache when a rack has mixed server cord types.

Technical Highlights:

• Per-Inlet Power Sensing: +/-0.2% accuracy on inlet voltage and current means the load numbers you pull for capacity planning are precise enough to actually size the next rack against, not just ballpark.
• 10kAIC Branch Circuit Breakers: UL489-compliant 2-pole 20A breakers give you per-branch fault isolation — one shorted outlet trips its own breaker instead of the whole PDU's 16A input.
• 16-Unit Daisy Chain: Cascading over a single IP address cuts management-port overhead significantly in a row of racks, which matters when your switch's management VLAN is already tight on ports.

Deployment Considerations:

• The hot-swappable controller separates intelligence from the outlet bar, so a controller replacement doesn't require de-energizing connected servers — plan controller spares accordingly rather than treating the whole PDU as one field-replaceable unit.
• Watch the outlet current ceilings: C13 outlets cap at 10A @ 230V L-N while Cx outlets cap at 16A — don't assume every outlet on this PDU shares the same per-outlet limit when load-balancing a rack.

This is the PDU to spec for a colocation cabinet running a mixed fleet of C14 and C20-corded servers where remote outlet cycling and inlet-level power quality data are part of the operational requirement, not an afterthought.
