HP ProCurve 2520-8-PoE Ethernet Switch J9137A#ABA 63
This review is from : HP Procurve 2520-8 Poe Switch
PoE Switch for security cams . I bought this switch to power three Vivotek (one outdoor 8361 and two indoor 8161) security cameras. One 8161 camera is on twenty feet of cable, the 8361 is on 75 feet and the other 8161 is at the end of about 150 feet. The cable is Cat 6, 23 AWG solid conductor with core separator to keep the pairs separated. For a short while, I had the 8361 at the end of 150 feet and it has the IR LEDs and internal heater. It drew somewhere around 7.4 Watts (47.4 Volts at 160mA). Without the LEDs, the 8361 pulls about 3.9 Watts (84mA) while the other two pull about 4.1 Watts (92-94mA), all at 47.4 to 47.5 Volts which makes sense since they're probably on the same Voltage rail inside the switch. In any case, I've never had to reboot the switch for any reason. The PoE power control on each port reliably switches power to a port on and off through the web browser interface control. I use one Gigabit uplink to talk directly to the gigabit my security camera server computer and the second to connect to my LAN, I can see how much power any one camera is pulling. I cannot see how much power each port is pulling on the PoE status screen which shows a list of all the ports and the PoE configuration status. I have to double-click a port to see its PoE electrical status. It updates this screen every few seconds.
Unfortunately, I haven't tested switch specific features such as VLANs tagged and untagged, QoS. I have tested the software for VLANs on the non PoE version of this switch to some extent. I was able to configure VLANs and tag them appropriately on ports that shared several VLANs but was unable to configure the connected Linux PC because its on-board NIC seemed to be unresponsive to configuring tagged VLANs even though it accepted the commands.
I'm very happy with this switch. I've had it on line non-stop since I bought it and it hasn't failed me yet and it's just warm to the touch in a 75 degree environment. The reliance and functionality of a network appliance is my concern so it gets 5 stars.
