Ciena 170-5160-900 optical transport power supply Power Supply

The Ciena 170-5160-900 is a DC power supply module sharing the same 170-xxxx-900 numbering family as the confirmed Ciena/Martek 170-0069-900 power supply, used across Ciena optical transport equipment. It converts site DC power into the regulated voltages required by the host chassis, supplying clean, filtered power to the card cage so that line cards, control processors and optical modules operate reliably in a telecoms-room or central-office environment. Genuine Ciena power modules such as this one are a routine requirement for maintaining full power redundancy on existing Ciena deployments or for replacing a failed unit quickly to avoid a service-affecting outage. As with other Ciena power supplies, it is designed for hot-swappable installation, allowing a faulty unit to be replaced without powering down the rest of the chassis. Precise electrical specification can vary by exact revision, so specifiers should confirm compatibility against their specific Ciena chassis configuration before ordering. Tech-Star (UK-based, shipped worldwide) stocks tested Ciena power supply modules to support ongoing network maintenance.
