IntelliSlot RDU120 Network Card

The Vertiv Liebert IntelliSlot RDU120 Network Card provides a dedicated communications interface for compatible Liebert power and thermal management units. It enables remote monitoring and management over a standard 1Gb Ethernet connection. This adapter is designed for facility managers and IT administrators who need secure, network-accessible visibility into critical infrastructure status and alarms.

Sustained monitoring operation

The card supports continuous data polling and alert transmission through its Ethernet link without the throughput spikes seen in bulk-data applications. Its RS-485 and USB ports maintain persistent links to the host UPS or cooling device for configuration and firmware updates. Steady-state operation is oriented toward reliability and log integrity rather than peak bandwidth utilisation.

UL 2900-1 cybersecurity baseline

The adapter meets the UL 2900-1 cybersecurity certification, establishing a recognised security posture for network-connected industrial equipment. This standard governs the product's own attack surface and communication hardening. It does not extend security guarantees to the broader management network, attached devices, or upstream monitoring software.

Questions about this item

Does the RDU120 generate noticeable heat or noise during continuous operation?

The RDU120 is a compact network card with no moving parts, so it runs silently and adds negligible heat inside the Liebert enclosure.

What existing Liebert hardware must I already have to install this card?

You need a compatible Liebert UPS or power distribution unit that provides an IntelliSlot bay for the RDU120 to plug into.

Will the RDU120 integrate with legacy Liebert equipment that uses RS-485?

Yes, the card includes an RS-485 port so it can communicate with older Liebert devices that rely on that serial interface.
