This ensures continuous uptime and serviceability, which is critical for network infrastructures requiring high availability. The PWR-460AC-F includes two hot-swappable power supplies configured for 1+1 redundancy and four hot-swap fans arranged in an N+1 redundant setup. This redundancy architecture ensures that the system remains operational even if a component fails, minimizing the risk of downtime.
Another notable feature of the PWR-460AC-F is the reversible airflow option, which provides flexibility in different deployment scenarios, allowing for optimal airflow management within the rack. The typical power draw of this unit is 125W, with a maximum of 220W under full load conditions, highlighting its efficiency in energy consumption relative to its output.
- Hot-swappable components include 1+1 redundant power supplies and N+1 redundant fans, ensuring uninterrupted operation.
- Supports up to 16 10GbE ports per link aggregation group (LAG), enhancing connectivity and bandwidth.
- Designed with color-coded power supply units (PSUs) and fans, characteristic of Arista's 1RU devices, simplifying maintenance procedures.
In line with Arista's focus on software excellence, the PWR-460AC-F benefits from live software patching and a self-healing software framework featuring Stateful Fault Repair (SFR). These capabilities ensure that the system can recover from faults without impacting network performance, further enhancing the reliability of the hardware.
The device supports extensive networking capabilities, including multi-chassis LAG for active/active layer 2 multipathing, and 32-way ECMP routing for efficient load balancing and redundancy. It can handle a significant number of networking parameters such as 128,000 MAC addresses, multiple spanning tree protocol (STP) instances, and thousands of access control lists (ACLs), making it suitable for complex, high-density networking environments.
Environmental specifications indicate an operating temperature range of 0 to 40°C and a storage temperature range from -40°C to 70°C. The PWR-460AC-F can operate at up to 10,000 feet altitude, with a relative humidity tolerance of 5 to 95%, non-condensing. Its physical dimensions are 19 inches in width, 1.75 inches in height, and 16 inches in depth, standard for 1RU devices, ensuring compatibility with standard data center racks.
In summary, the Arista PWR-460AC-F power supply is engineered to deliver reliable, efficient power for critical network hardware. Its design emphasizes redundancy, serviceability, and flexibility, making it a suitable choice for data centers seeking to minimize downtime and optimize operational efficiency.
