1000 Mb latency
< 2.3 µs (LIFO 64-byte packets) 100 Mb Latency < 7.4 µs (LIFO 64-byte packets) Throughput Up to 77.3 million pps (64-byte packets) Switching capacity 104 Gb/s MAC address table size 16000 entries Physical specifications Dimensions (W x D x H) 44.3 x 32.26 x 4.45 cm (17.44 x 13.00 x 1.75 in) (1U height) Weight 4.72 kg (10.4 lb) Electrical specifications Maximum heat dissipation 236 BTU/hr (248.98 kJ/hr), (switch only: 236 BTU/hr; combined switch + max. PoE devices: 1624 BTU/hr) Voltage 100 - 127 / 200 - 240 V ac Current 5.8/2.9 A Idle power1 40.1 W Maximum power rating2 476 W PoE power 382 W Frequency 50/60 Hz NOTE: 1: Idle power is the actual power consumption of the device with no ports connected. 2: Maximum power rating and maximum heat dissipation are the worst-case theoretical maximum numbers provided for planning the infrastructure with fully loaded PoE (if equipped), 100% traffic, all ports plugged in, and all modules populated. PoE power is the total power budget available to all PoE ports.
