Eaton PDUB201U – Hot-Swap Bypass PDU, 120V, 1U Rack/Wall

Product Overview

The Eaton PDUB201U is a 120V, 20A single-phase hot-swap bypass PDU designed to keep mission-critical data center equipment powered during scheduled UPS maintenance. This rack PDU allows facilities staff to manually transfer connected equipment to utility power through the unit's bypass switch, enabling UPS maintenance or replacement without interrupting downstream servers or network gear. It's a purpose-built solution for data centers that cannot tolerate the downtime typically required for UPS upkeep.

Product Description

Working in conjunction with an existing UPS system, the PDUB201U lets facilities and IT staff manually transfer connected rack equipment to utility power via a bypass switch built into the PDU. This allows UPS maintenance, battery replacement, or full UPS swap-out to happen without powering down the servers and network devices relying on that circuit, keeping mission-critical infrastructure online 24/7/365. The unit provides six NEMA 5-20R outlets fed by two 5-20P inputs, giving flexibility in how upstream power sources are connected. Housed in a 1U form factor, the PDUB201U installs in a standard 19-inch rack or can be wall-mounted where rack space is limited, such as in smaller network closets or auxiliary equipment rooms. For data centers and server rooms running a single UPS per rack, this bypass PDU closes a common maintenance gap: the ability to service the UPS itself without a planned equipment outage.

Frequently Asked Questions

What is the purpose of the manual bypass switch?

The bypass switch lets you manually transfer connected equipment to utility power so the UPS feeding this PDU can be serviced, replaced, or maintained without interrupting power to downstream equipment.

Can this PDU be wall-mounted instead of rack-mounted?

Yes. The PDUB201U supports both 1U rack installation in a standard 19-inch rack and wall mounting for space-constrained network closets or equipment rooms.

Does this PDU work with any UPS, or only specific models?

The PDUB201U is designed to work in conjunction with a UPS system feeding its inputs; confirm your specific UPS output configuration is compatible with the unit's 5-20P input requirements before installation.

Is switching to bypass power automatic or does it require staff action?

Bypass transfer on this unit is manual, requiring facilities or IT staff to operate the bypass switch when UPS maintenance is being performed.

What warranty does Eaton provide on this unit?

Eaton backs this unit with its standard manufacturer warranty; contact Creation Networks for the current term and any extended coverage options.
