Connection to a Power CIM peer is through an external USB dongle (DSER-PWR-USB-G4 or DKX3-PWR-USB-G4) and the USB-A port.
USB-B is available for direct CLI connection. For Serial/CLI applications over RJ45, an external DSER-CLI-USB-G4 dongle is needed.

Using the PDU Link Port with a standard Cat5 connection, the Controller provides active redundant power to a second like-designed and versioned PDU controller, maintaining sensor connection and network visibility in case of an outage on the PDU infeed.

Link up to 8 PDUs where the Primary PDU has knowledge and power information from the attached Expansion PDUs. Redundant power from the first expansion unit ensures uptime even if the Primary PDU loses power.

Via the PDU Link Port, linking is the logical connectivity of devices using the PDU Link port within the same rack/cabinet. Where you can link a single Primary PDU with multiple Link PDUs for more efficient power management. Includes the ability to power share across linked units.

Physically cascade 32 PDUs under one ethernet port or 16 PDUs with USB using bridging mode, or additionally, save IP addresses using a single IP address with port forwarding.

Supported through the external DX2-WIFI-KIT, a USB Wi-Fi antenna that connects a USB-A port to a Wi-Fi network.

PDU to PDU cascading up to 32 devices, bulk configuration, webcams, console serial connection, and mobile interface support on tablets or smartphones.

Settings updates, bulk configuration, backup/restore, and firmware updates.
Local Connection: USB flash drive, PDView App (available on iOS or Android), and CLI.
Remote Management: TFTP Server, SSH / Command Line Interface (CLI), Web User Interface (HTTPS).

Compatible with the Sensor Port, the plug-and-play sensor bus allows up to 32 sensor functions or 12 sensor packages to attach to each PDU.

SmartSensors supported: temperature, humidity, airflow, differential air pressure, water/leaks, dust/particles, contact closures, dry contacts, proximity/motion, and vibration. Sensor hubs are also supported. (Accessories are sold separately.)

HTTP(S); SSH Command Line Interface; Telnet; SNMP v2/v3; SMTP (email); IPv6/IPv4; MODBUS/TCP.

Server Technology PRO4X Rack PDUs are IPv6 Ready — see our IPv6 Ready Gold Logo ID #02-C-002956 . Our PDUs also meet the USGv6-r1 capabilities for Core, SLAAC, Address Architecture, and IPv6-Only — see our USGv6 registry profile .

Receive alerts via SNMP TRAPs and INFORMs, email (SMTP), and Syslog when predefined thresholds are exceeded, among other power and environmental events. Identical SNMP MIBs across all PDU families.

Automate intelligent PDU functions with Redfish RESTful APIs, JSON-RPC, cURL support, and LUA scripting. SDKs are available in Perl, Python, JavaScript, and C#/.NET.

Configurable firewall (in/outbound traffic control).

Granular user/user group permissions.

Configurable strong passwords allow defining a minimal requirement for password length and complexity; a limited password history prevents reusing passwords, and password expiration ensures passwords are refreshed periodically.

A third-party consultant conducted a comprehensive VAPT (Vulnerability Assessment and Penetration Testing) and IoT device security assessment on PRO4X PDUs: testing results determined that they are secured in a manner consistent with industry best practices.

Configured with Secure Boot to protect against boot sector viruses, rootkits, and other malware that might try to interfere with the PDU's startup process.
