Universal Electric Corporation — 2 prefixes (MA-L)

Universal Electric Corporation holds two IEEE MA-L blocks — D8:24:77 and 58:2F:42 — both registered to the identical string "Universal Electric Corporation" at 168 Georgetown Road, Canonsburg, PA 15317, US. That Canonsburg-area registry address, together with the network-hardware nature of an OUI assignment, points to the Universal Electric Corporation (UEC) that makes the Starline brand of overhead track busway and data-center power distribution/monitoring systems — the company acquired by Legrand, North and Central America in 2019 and now run under Legrand's Data, Power and Control division. The devices that plausibly carry these MACs are network-attached power-monitoring appliances such as the Starline Critical Power Monitor (CPM/M70), an Ethernet/serial meter that exposes a web UI plus SNMP, BACnet, and Modbus TCP/RTU on data-center management networks. Two important cautions apply. First, do not confuse this company with "Universal Electronics, Inc." (Santa Ana, CA), a different similarly named firm that holds its own separate OUI blocks (e.g. E8:0F:C8, 48:D0:CF). Second, a firm also named "Universal Electric Corporation" operates as an unrelated electrical-contracting business at universalelectriccorp.com; name alone cannot decide which entity holds these prefixes, though a busway/monitoring manufacturer is by far the more likely OUI registrant. IEEE publishes no assignment date for MA-L blocks, so none is recorded here.

IEEE assignment

2 prefixes → Universal Electric Corporation, registered Canonsburg, PA, US [Confirmed] — IEEE MA-L (lines 25640, 27729)

Registry / block size

MA-L (24-bit OUI); 2 prefixes. Verified only in the IEEE MA-L registry — no matching entries for this org in the IEEE MA-M registry (MA-M) or the IEEE MA-S registry (MA-S). [Confirmed] — IEEE MA-L (the IEEE MA-M registry, the IEEE MA-S registry). NOTE: IEEE public OUI data publishes NO assignment/registration date; any "date registered" on third-party tools is a database artifact, not an IEEE fact.

Device types

network-attached power distribution / metering hardware; notably the Starline Critical Power Monitor (CPM, model M70), an Ethernet/serial meter with web UI, SNMP, BACnet, Modbus TCP/RTU (some deployments add 802.11n Wi-Fi) [Likely] — https://www.legrand.us/critical-power-and-infrastructure/track-busway/critical-power-monitor , http://www.packetpower.com/blog/Wireless-Data-Center-Monitoring-Now-Available-on-Starline-Products

Notable products

Starline Track Busway, Starline Critical Power Monitor (CPM/M70) [Likely] — https://starlinepower.com/

Security context

No CVE or public vulnerability disclosure was found naming Universal Electric, Starline, or the CPM/M70 in this pass (absence of findings, not proof of none). This is a network-attached OT/monitoring device class (webUI + SNMP + Modbus + BACnet) — a general OT-security risk class for default-credential and legacy-protocol exposure, not a documented finding about this product.

Disambiguation

NOT "Universal Electronics, Inc." (Santa Ana, CA), which holds its own separate OUIs (e.g. E8:0F:C8, 48:D0:CF). Also distinct from the identically named electrical-contracting firm at universalelectriccorp.com; OUI registrant match is the Canonsburg, PA "Universal Electric Corporation" string.

[Confirmed] — IEEE MA-L

IANA Reference

not applicable — OUI/MAC vendor entries have no IANA Reference column [Confirmed] — IEEE MA-L

Analyst note

The company identity (Starline/UEC/Legrand) is inferred from the Canonsburg registry address and the network-device nature of the assignment; it is not confirmed against an IEEE registrant record beyond the org-name string, hence [Likely]. Registry facts (prefixes, org string, address) are [Confirmed].
