- Support for jumbo frames up to 9,216 bytes.
- Operating temperature ranges from 32° F to 113° F, with storage temperatures spanning from -40° F to 158° F.
- The operating altitude reaches up to 10,000 ft (3,049 m), and non-operating altitude up to 16,000 ft (4,877 m).
- Relative humidity levels during operation and non-operation vary from 10% to 85% and 0% to 95% (non-condensing), respectively.
- Supports high-density, multi-rate 10GbE environments.
- Equipped with advanced features for network optimization and security.
- Designed for reliability and easy management in dynamic network environments.
