Server Technology C2SG48TE-DFME2M99 48-Outlet Switched PRO2 Rack PDU

Overview

The Server Technology C2SG48TE-DFME2M99 is a vertical Switched PRO2 power distribution unit built for data center and network operations center racks that need granular, remote-controllable power at scale. It's a 0U vertical mount unit, 80 inches tall and only 2.2 inches wide by 2.5 inches deep, so it runs the full height of a standard rack cabinet without eating into usable rack unit space for servers, switches, or patch panels. Input is 208V at 50/60 Hz through a CS8365 3P+G 50A plug, rated for 40A continuous input current and 14.4 kW of total input power capacity — enough headroom for a densely populated server or network rack without derating concerns. If you're standardizing PDUs across a colocation footprint or building out a new server room from scratch, this unit fits the same architecture as other units in the Server Technology catalog, which simplifies spares planning and firmware management across a rack fleet.

Key Features

• 48 Switched Outlets (C13/Cx mix): Individually switched outlets rated up to 12A @ 208V L-L on C13 positions and up to 16A @ 208V L-L on Cx positions let you remotely cycle power to a hung server or misbehaving switch without a trip to the data hall — critical when the rack is in a remote colo or a locked cage.
• Branch Circuit Protection at 16A, 10 kAIC: Each branch circuit breaker is rated ≤16A with a 10 kAIC interrupt rating, isolating a fault to a single branch instead of tripping the whole PDU and taking down every device downstream.
• Gigabit Ethernet Management (10/100/1000 Mbps): Full gigabit connectivity means the PDU's web interface and SNMP polling won't bottleneck on a busy management VLAN, and it keeps pace with modern out-of-band network designs.
• RS-232 Serial + RJ-12 Link Port: Serial console access covers initial configuration or environments where IP connectivity to the management network isn't available yet, and the RJ-12 link port supports daisy-chaining additional PRO2 units under one network connection — fewer IP addresses to manage per rack row.
• Two Temperature Sensor Inputs: Two onboard ports for environmental probes give you rack-level thermal visibility (hot aisle creep, failed CRAC unit) without a separate environmental monitoring appliance.
• Broad Protocol Support: HTTP/HTTPS, TLSv1.2, SSHv2, Telnet, SNMPv2c/v3, IPv4/IPv6, LDAPv3/LDAPS, TACACS+, RADIUS, and FTP/SFTP cover encrypted management, centralized authentication (LDAP, TACACS+, RADIUS), and automated firmware or config transfer — this integrates into an existing enterprise AAA setup rather than forcing a standalone local-account model.
• Quiescent Power Draw Under 10W: The PDU's own overhead is negligible against a 14.4 kW capacity, so it isn't eating into the power budget you're allocating to actual IT load.
• Wide Operating Range — 0°C to 60°C, 8-90% RH Non-Condensing: The 60°C high-temperature rating means this unit tolerates hot aisle conditions or a marginally-cooled edge/telecom room where a standard-rated PDU would be out of spec.
• Storage Range to -30°C / 80°C: Relevant for spares kept in an unconditioned warehouse or shipped through extreme climates before installation.
• Rated to 6,500 ft Operating Elevation: Covers most continental US data center sites, including higher-altitude metros, without a derating conversation.
• UL 62368-1 / CSA C22.2 No. 62368-1 Safety Listing: North American safety certification relevant for insurance, AHJ inspection, and facilities compliance documentation.
• FCC Part 15 Subpart B Class A / CAN ICES-003 Class A EMC: Class A emissions certification appropriate for commercial and industrial environments, not residential.

Integration & Compatibility

The C2SG48TE-DFME2M99 (often searched as C2SG48TE DFME2M99) is designed to sit alongside standard 19-inch or 23-inch rack infrastructure as a 0U vertical PDU, freeing horizontal rack units for compute and network gear. Its SNMPv2c/v3 support means it drops into existing monitoring stacks (data center infrastructure management platforms, NMS polling) without a proprietary agent, and LDAPv3/LDAPS plus TACACS+/RADIUS support let it authenticate against the same directory and AAA infrastructure already governing switches and console servers in the rack. For facilities planning a multi-rack rollout, pair this unit's layout against your power distribution and PDU lineup to standardize outlet counts and input plug types across racks, and review a power and capacity planning guide before finalizing breaker and circuit assignments — 14.4 kW per PDU adds up fast across a full row.

Frequently Asked Questions

When I spec a vertical PDU for a dense server rack, the input capacity is the first thing I check against the rack's actual load, and the C2SG48TE-DFME2M99 gives you 14.4 kW at 40A on a 208V CS8365 3P+G plug — that's a real number to build a circuit schedule around, not a marketing figure.

Technical Highlights:

• 48 individually switched outlets: C13 positions capped at 12A @ 208V L-L and Cx positions at 16A @ 208V L-L means you can remote-cycle a single hung device without touching neighboring outlets — I lean on this constantly for out-of-band recovery on locked cages.
• 10 kAIC branch breakers at ≤16A: That interrupt rating isolates a downstream fault to one branch circuit instead of dropping the whole PDU, which matters when 48 outlets' worth of gear share one unit.
• 0U footprint at 80in x 2.2in x 2.5in: Full rack-height vertical mount means zero horizontal RU consumed — every U stays available for compute, and 2.2 inches of width barely intrudes on cable channels.

Deployment Considerations:

• The CS8365 3P+G 50A input plug is a locking three-phase connector — confirm your PDU whip and receptacle are already provisioned for it before the unit shows up on site, since it's not a field-swappable IEC cord.
• Quiescent draw is under 10W, which is trivial against 14.4 kW capacity, but remember that figure is the PDU's own overhead — your actual usable IT load still needs to respect the 40A/16A branch limits after derating for continuous-load code requirements.

This is the right PDU for a colocation cage or NOC rack row standardizing on gigabit-managed, LDAP/RADIUS-authenticated power distribution — anywhere you need per-outlet remote control across 48 device connections without burning rack units to get it.
