Product Description

The PWR-2700-AC is housed in a 5RU (8.75-in.) chassis and supports an AC Power supply with power requirements ranging from 110 to 240 VAC and –48 to –60 VDC. It is designed for durability with a Mean Time Between Failure (MTBF) of 7 years for system configuration, operating effectively within a temperature range of 32°F (0°C) to 104°F (40°C) and a storage temperature range from –4°F (–20°C) to 149°F (65°C). The device maintains operational integrity in environments with 10% to 85% noncondensing relative humidity during operation and 5% to 95% noncondensing relative humidity during storage.

  • What is the significance of the MTBF rating?
    The MTBF rating of 7 years indicates the expected operational lifespan of the system configuration under normal conditions.

Product Review

The Cisco PWR-2700-AC power supply supports a wide range of input voltages (110 to 240 VAC and –48 to –60 VDC), making it versatile across various power infrastructures. With a mean time between failure (MTBF) of 7 years, it promises reliability in system configurations. However, its operating temperature range is limited to 32 °F to 104 °F, which may restrict its use in environments with extreme temperatures.


The Cisco PWR-2700-AC is designed to meet the power needs of demanding network environments. This power supply unit (PSU) is compatible with a 5RU (8.75-inch) chassis, ensuring it fits into a variety of networking cabinets and racks with ease. Its flexibility is further demonstrated by its ability to operate on both AC power, with requirements ranging from 110 to 240 VAC, and DC power, accepting input voltages from –48 to –60 VDC. This versatility makes the PWR-2700-AC an ideal choice for a wide range of network infrastructures, accommodating various global electrical standards and providing uninterrupted service across different power sources. Durability and reliability are key aspects of the PWR-2700-AC, with a mean time between failure (MTBF) of seven years for system configurations. This statistic underscores the unit's reliability in continuous operation, reducing the likelihood of downtime and the need for frequent replacements. The PSU is designed to perform optimally within a broad range of environmental conditions. It operates efficiently at temperatures as low as 32 °F (0 °C) and as high as 104°F (40°C), ensuring stability in both cooler and warmer climates. Storage temperature tolerances are also wide, ranging from –4 °F (–20°C) to 149°F (65°C), which guarantees the PSU's integrity and performance even when stored in extreme conditions. Humidity levels can significantly affect electronic equipment. The Cisco PWR-2700-AC is engineered to withstand a wide range of humidity levels, ensuring reliable performance through varying atmospheric conditions. When operating, it can handle relative humidity levels from 10% noncondensing to 85% noncondensing. While in storage, its tolerance expands further, accommodating humidity levels from 5% noncondensing to 95% noncondensing. These specifications indicate the PSU's resilience against moisture, contributing to its long-term reliability and reducing the risk of damage due to environmental factors. Key features of the Cisco PWR-2700-AC include: -
  • Compatibility with 5RU (8.75-inch) chassis, ensuring a good fit in standard network racks and cabinets.
  • Dual AC and DC power input capability, offering flexibility in various power environments (110 to 240 VAC and –48 to –60 VDC).
  • A strong MTBF of seven years, indicating reliable, long-term operation within system configurations.
In summary, the Cisco PWR-2700-AC is a versatile and reliable power supply unit that caters to a wide range of network environments. With its broad compatibility, flexible power input options, and robust environmental tolerances, it represents a strategic investment for organizations seeking to minimize downtime and ensure consistent network performance. Whether deployed in data centers, communication closets, or industrial settings, the PWR-2700-AC stands out as a resilient component in supporting critical network operations.
