CyberPower 200-240V 42 Outlet Hubbell CS8365C - PDU33108

CyberPower PDU33108 Three-Phase Monitored 0U Rack PDU, 42 Outlets, 200–240V

Overview

The CyberPower PDU33108 is a three-phase, 200–240V monitored rack PDU delivering 42 AC outlets in a 0U vertical form factor — the configuration to reach for when a dense server or network rack needs granular power visibility without sacrificing a single rack unit to the unit itself. Unlike basic strip PDUs, the PDU33108 provides real-time monitoring via a built-in LCD display and a dual-port Ethernet management interface, giving operations teams per-unit current draw data and remote visibility over the full CyberPower power management line.

The Hubbell CS8365C input plug (rated for three-phase 200–240V feeds) anchors the PDU33108 to the type of facility power distribution found in data centers, enterprise server rooms, and high-density compute environments where single-phase capacity simply isn't enough. The 3-meter cable gives integrators enough slack to route cleanly from overhead busway or floor PDU panels without stressing the inlet.

Key Features

• 42 AC Outlets (IEC 320 receptacles): Forty-two individually accessible IEC 320 outlets cover a fully populated 42U rack with room for redundant power connections on dual-PSU servers — no sharing required. IEC 320 compatibility supports the C13 and C19 receptacle mix standard in enterprise equipment without adapter proliferation.
• Three-Phase Input, 200–240V / 50–60Hz: Three-phase distribution balances load across phases, reducing neutral current and associated heat in the power chain. The 50–60Hz input range means this unit works on both North American and international facility power without derating.
• 0U Vertical Form Factor (Metal Housing): The 0U rack mount profile installs vertically in the rear channel of a standard rack, preserving every rack unit for revenue-generating equipment. The all-metal housing resists deformation under the weight of dense cabling and provides a ground path without relying solely on the rack rail.
• Dual Ethernet (RJ-45) Management Ports: Two RJ-45 ports support daisy-chaining or dual-NIC network attachment for management redundancy. Remote monitoring, alert configuration, and protocol access are available without touching the data-plane network if needed.
• LCD Display: The front-panel LCD provides at-a-glance input current, voltage, and power readings without requiring a laptop or a network connection — useful during initial commissioning or troubleshooting when the management network isn't yet live.
• SNMPv1/v3, SSH, TLS, HTTPS, LDAP(S), RADIUS: The full enterprise protocol stack means the PDU33108 slots into existing NMS infrastructure (SolarWinds, PRTG, Nagios, or any SNMP-capable platform) without forcing a parallel management silo. SNMPv3 provides authenticated and encrypted polling. SSH and HTTPS secure CLI and web-UI sessions. LDAP(S) and RADIUS allow centralized credential management — no local account sprawl on 20 PDUs.
• IPv4/IPv6 Dual-Stack: Native IPv6 support means the PDU33108 won't become a blocker when facility networks complete their IPv6 transition. Configure it on IPv4 today; assign an IPv6 address without hardware changes later.
• Windows AD Integration: Active Directory integration via LDAP(S) lets security teams enforce role-based access control on PDU management using the same directory they manage server access through — a non-trivial operational simplification in environments with compliance requirements.
• USB Firmware Upgrade: Firmware updates apply via the USB port using a standard flash drive — no TFTP server, no network-accessible management station required. Field updates are straightforward even in air-gapped environments.
• Syslog and SMTP Alerting: Syslog output integrates with centralized log aggregation (Splunk, Graylog, etc.). SMTP alerting sends threshold-breach notifications directly to operations mailboxes without requiring a separate monitoring agent on each PDU.
• NTP Time Synchronization: NTP keeps PDU event timestamps accurate and correlated with server and network logs — critical for root-cause analysis when a power anomaly triggers a cascade of alerts across infrastructure systems.

Integration & Compatibility

The PDU33108 supports SNMPv1/v3 polling and integrates with any NMS platform capable of importing a standard MIB file. The dual RJ-45 ports and support for UDP, Syslog, CLI, and Windows AD make it straightforward to fit into existing enterprise monitoring and access-control frameworks. The Hubbell CS8365C plug requires a matching three-phase receptacle on the facility power panel — confirm the local power infrastructure supports three-phase 200–240V before ordering. The IEC 320 outlet bank accommodates standard C13/C19 locking or non-locking cords used by server and networking equipment from major manufacturers.

For environments running parallel UPS systems, the PDU33108 can be fed from a three-phase UPS output, providing both conditioning and monitored distribution in a single rack footprint. The 3-meter input cable is long enough for most overhead or underfloor routing scenarios; measure the panel-to-rack distance before installation to confirm no extension is needed.

Frequently Asked Questions

Q: What input plug does the PDU33108 use?

A: The PDU33108 ships with a Hubbell CS8365C input plug, designed for three-phase 200–240V facility power. Confirm your power panel has a matching CS8365C receptacle before installation.

Q: Does the PDU33108 occupy rack unit space?

A: No. The PDU33108 is a 0U device that mounts vertically in the rear cable channel of a standard rack, preserving all usable rack units for active equipment.

Q: What management protocols does the PDU33108 support?

A: The PDU33108 supports SNMPv1, SNMPv3, HTTP, HTTPS, TLS, SSH, Telnet, FTP, SMTP, NTP, DNS, DHCP, LDAP(S), RADIUS, TCP/IP, IPv4, and IPv6 — covering the full enterprise NMS and access-management stack.

Q: Can firmware be updated remotely or does it require physical access?

A: Firmware can be upgraded via the USB port using a standard flash drive. Physical access to the PDU is required for this method; check with CyberPower for any available network-based update options.

Q: How many network ports does the PDU33108 have?

A: Two RJ-45 Ethernet ports are included, enabling daisy-chain management of multiple PDUs or dual-path network attachment for management redundancy.

Q: What outlet type does the PDU33108 use?

A: The PDU33108 provides 42 IEC 320 receptacles, compatible with standard C13 and C19 power cords used by the majority of rack-mount servers, switches, and networking equipment.
