|MAC address table size||16000 entries|
|Dimensions (W x D x H)||44.3 x 33.02 x 4.45 cm (17.44 x 13.00 x 1.75 in) (1U height)|
|Weight||3.95 kg (8.7 lb)|
|Maximum heat dissipation||135 BTU/hr (142.42 kJ/hr), (switch only: 135 BTU/hr; combined switch + max. PoE devices: 843 BTU/hr)|
|Voltage||100 – 127 / 200 – 240 V ac|
|Idle power1||25.2 W|
|Maximum power rating2||247 W|
|PoE power||195 W|
|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.
