Mounting options are versatile, with the capability to install the switch in a standard 19-inch telco rack, on a horizontal surface, or mounted on a wall, catering to various deployment scenarios. Its compact dimensions, measuring 44.2 cm in width, 32.26 cm in depth, and 4.45 cm in height, conform to the 1U standard, ensuring it fits seamlessly into any network infrastructure without consuming excessive space.
The switch's weight is 4.58 kg, making it relatively lightweight and easy to handle during installation. It operates within a power budget that includes an idle power consumption of 37.5 W and a maximum power rating of 441 W. The PoE power capacity is 382 W, enabling the delivery of sufficient power to connected PoE devices.
- Maximum heat dissipation stands at 170 BTU/hr for the switch alone, and 1505 BTU/hr when operating at full capacity with PoE devices connected.
- The operational environment specifications indicate a working temperature range from 0° to 45°C and a relative humidity tolerance from 15% to 95% at 40°C, non-condensing.
- Performance metrics include a 1000 Mb latency of less than 2.2 µs and a 100 Mb latency of less than 6.6 µs, with a throughput capability of up to 13 million packets per second for 64-byte packets, ensuring efficient data handling and minimal delay.
