Nortel NTRX51LE (telecommunications transmission and networking portfolio) Power Supply

The Nortel NTRX51LE is a hot-swap DC power supply module (field-replaceable unit) built for the Netra 240 platform that underpins Nortel’s Succession Communication Server hardware, cross-referenced against independent listings under the equivalent part numbers B0263268, 3001567-04 and AA22780. Succession CS 2000/2100 signalling and call-processing servers used Sun Netra 240 chassis as their compute platform, and this DC-input supply feeds that chassis in telecom environments where AC mains are not standard. As a hot-swap unit it can be pulled and replaced without powering down the host server, which keeps a redundant Netra 240 pair online through a failed-supply event. Genuine Succession-era spares such as this one remain a routine requirement for operators still running Nortel’s carrier voice-switching platforms, since new-build Netra 240 power modules are long out of production. Specifiers should confirm the exact chassis revision and DC voltage range before ordering. Tech-Star (UK-based, shipped worldwide) supplies Nortel Succession spares to support ongoing network maintenance projects.
