Server Technology C2X48TE-5PAE2M99/C Switched Expansion PDU, 48-Outlet 415V 3-Phase

Overview

The Server Technology C2X48TE-5PAE2M99/C is a switched expansion PDU from the PRO2 series, built for data center racks that need outlet-level power control across 48 receptacles on a 415V 3-phase Wye feed. As an expansion unit, it's designed to pair with a PRO2 primary unit to extend outlet-level switching to a second rack or an adjacent zone without adding a second network management point — useful when you're scaling rack density without scaling your management overhead. C2X48TE-5PAE2M99/C (often searched as C2X48TE 5PAE2M99/C) fits environments where per-outlet remote power cycling matters: colocation cages, NOC racks, and any deployment where a hung server shouldn't require a physical dispatch to power-cycle.

Key Features

• Switched outlet control: Every one of the 48 outlets can be turned on, off, or cycled independently over the network — so a locked-up server or switch gets power-cycled remotely instead of waiting on a hands-on-glass visit to the cage.
• 48 HDOT outlets: High-density outlet technology packs 48 receptacles into the PDU's rack footprint, which matters when you're powering dense 1U/2U server counts and don't want to run out of outlets before you run out of rack space.
• Configurable alternating phase layout: Outlets alternate across phases by design, which helps balance load across the three phases automatically as you populate the rack — reduces the manual math (and the risk of an unbalanced phase tripping a breaker) during rack-out.
• 415V 3-phase Wye input: Wye topology delivers both phase-to-phase and phase-to-neutral voltage from a single feed, giving you flexibility in how downstream equipment is wired without a separate transformer.
• 30A input current: Rated input draw sized for high-density rack loads — confirm your upstream breaker and whip are provisioned for 30A continuous before commissioning.
• 6-breaker configuration: Outlets are split across 6 branch breakers, so a single overloaded branch trips in isolation instead of taking the whole PDU's outlet bank down — a fault on one branch doesn't cascade into a rack-wide outage.
• PRO2 series expansion architecture: As an expansion unit in the PRO2 family, this model extends switched outlet capacity from a primary PRO2 unit, letting you scale outlet count across multiple PDUs under one logical management scheme instead of standing up redundant network endpoints.

Integration & Compatibility

The C2X48TE-5PAE2M99/C is built to expand a PRO2 primary switched PDU deployment, extending the same outlet-level switching and monitoring model across additional PDU units in a rack or row. This is a fit for facilities already standardized on the Server Technology PDU line looking to add outlet capacity without introducing a second management platform. Before ordering, confirm your upstream distribution matches the 415V 3-phase Wye, 30A input spec — mismatched service voltage is the single most common PDU commissioning delay. For broader rack power planning, including how to size branch circuits and balance phases across a row, see the PDU and power distribution planning guide. Pair this expansion unit with the correct rack power supplies and whips for your facility's electrical service, and review network video recorders and switch racks in the same row if you're standardizing power delivery across a mixed compute and surveillance environment. For structured cabling and rack layout planning alongside PDU installs, the rack mount accessories category covers cable management and PDU mounting brackets.

Frequently Asked Questions

Q: Is the C2X48TE-5PAE2M99/C a standalone PDU or does it require a primary unit?

A: It's an expansion unit in the PRO2 series, designed to extend switched outlet capacity from a PRO2 primary unit rather than operate as a fully standalone network-managed PDU.

Q: How many outlets does the C2X48TE-5PAE2M99/C have?

A: 48 HDOT (high-density outlet technology) receptacles, configured with alternating phase assignment across 6 branch breakers.

Q: What input voltage and current does the C2X48TE-5PAE2M99/C require?

A: 415V 3-phase Wye at 30A input current.

Q: Can outlets on the C2X48TE-5PAE2M99/C be switched individually?

A: Yes, this is a switched PDU — each of the 48 outlets supports independent on/off/cycle control.

Q: How many branch breakers does the C2X48TE-5PAE2M99/C use?

A: Six branch breakers split the outlet load, isolating faults to a single branch rather than the full outlet bank.

Jerry Tildsen

The C2X48TE-5PAE2M99/C is one I'd spec for a rack row that's already running PRO2 primaries and just needs more switched outlet count without adding another IP address to manage. 48 HDOT outlets on a single expansion chassis is a lot of density, and the configurable alternating phase layout does real work balancing that 415V 3-phase Wye feed as you populate it.

Technical Highlights:

• 48 HDOT outlets: high-density receptacle layout keeps outlet count high relative to rack unit footprint — important when 1U server counts climb and outlet scarcity becomes the bottleneck before power capacity does.
• 6-breaker branch configuration: isolates a branch-level fault to roughly 8 outlets instead of the full 48-outlet bank, which limits blast radius on a breaker trip.
• 415V 3-phase Wye at 30A input: matches European and international 3-phase service standards directly — confirm your facility's distribution voltage before ordering since this isn't a 208V domestic Delta unit.

Deployment Considerations:

• This is an expansion unit, not a standalone — it needs a PRO2 primary switched PDU in the same logical group to provide network management; don't order it expecting an independent IP-addressable controller.
• Verify upstream whip and breaker sizing against the 30A input rating before rack-in — undersizing the feed circuit is the most common install delay on high-density 3-phase PDUs.

This is the right call for a colocation or enterprise data center row already standardized on PRO2 primaries that needs to add a second fully-switched 48-outlet rack without doubling the management footprint — not a fit for a single-rack deployment that has no primary PRO2 unit to expand from.
