HP A5120-24G-PoE EI Switch (JE070A), 2x expansion slot, 20xGLAN, 4xSFP/GLAN

Ports 20 RJ-45 autosensing 10/100/1000 PoE ports (IEEE 802.3 Type 10Base-T, IEEE 802.3u Type 100Base-TX, IEEE 802.3ab Type 1000Base-T, IEEE 802.3af PoE); Duplex: 10Base-T/100Base-TX: half or full; 1000Base-T: full only 4 dual-personality ports; PoE auto-sensing 10/100/1000Base-T or SPF 2 port expansion module slots 1 RJ-45 serial console port Physical characteristics Dimensions 16.54(d) x 17.32(w) x 17.17(h) in. (42 x 44 x 43.6 cm) (1U height) Weight 15.43 lb. (7 kg) Memory and processor 128 MB SDRAM, 16 MB flash; packet buffer size: 2 MB Mounting Mounts in an EIA-standard 19 in. telco rack or equipment cabinet (hardware included) Performance 1000 Mb Latency < 3.2 µs 10 Gbps Latency < 2.6 µs Throughput 95.2 million pps Routing/Switching capacity 128 Gbps Routing table size 32 entries Environment Operating temperature 32°F to 113°F (0°C to 45°C) Operating relative humidity 10% to 90%, noncondensing Nonoperating/Storage temperature -40°F to 158°F (-40°C to 70°C) Nonoperating/Storage relative humidity 5% to 95%, noncondensing Electrical characteristics Maximum heat dissipation 1689 BTU/hr (1781.9 kJ/hr) Voltage 100-240 VAC DC Voltage -52 to -55 VDC Idle power 55 W Maximum power rating 495 W PoE power 370 W Frequency 50 / 60 Hz Notes Idle power is the actual power consumption of the device with no ports connected. 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 power supplied by the internal power supply; it is dependent on the type and quantity of power supplies and may be supplemented with the use of an External Power Supply (EPS).
