Ciena 170-0069-900 (Martek) telecom power supply Power Supply

The Ciena 170-0069-900 is a Martek-manufactured DC power supply module used across Ciena optical transport and telecom equipment, accepting a 20-60VDC input range typical of telecoms-room and central-office -48V power plants. 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. This wide DC input range gives it tolerance for the voltage variation commonly seen on battery-backed telecoms power feeds, making it a dependable choice for continuous, mission-critical operation in a central office or data-centre environment. As with most telecom power modules, it is designed for hot-swappable installation, allowing a faulty unit to be replaced without powering down the rest of the chassis, which is essential for maintaining uptime on live optical transport equipment. Genuine Ciena power supplies 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.
