The HP ProCurve 2520G-PoE Switches are multiport switches designed for high-performance switched workgroup networks. They utilize store-and-forward technology for low latency and high-speed networking. These switches also support Power over Ethernet (PoE) technology, allowing IP phones, wireless access points, and other appliances to receive both power and data over standard LAN cabling. The switches offer features like auto-sensing 10/100/1000Base-T RJ-45 ports with Auto-MDIX, dual-personality uplink ports (RJ-45 or mini-GBIC), plug-and-play networking, and comprehensive management interfaces (console, web browser, SNMP). The 2520G-24-PoE can provide up to 195 watts of PoE power, while the 2520G-8-PoE provides 67 watts. Each port can supply up to 15.4 watts of PoE power.

Installation involves preparing the site, mounting the switch (rack, wall, or surface), connecting to a power source, and connecting network cables. Configuration can be done via a console port or a web browser interface.

Troubleshooting and error codes

Switch LEDs	State	Meaning
Power (green)	On	The internal power supply is working properly.
	Off	No power connection. The switch is NOT receiving power.
Fault (orange)	Off	The normal state; indicates there are no fault conditions on the switch.
	Flashing²	A fault has occurred with a component on the switch. The Status LED for the component with the fault will flash simultaneously.
Locator (blue)	On	On briefly after the switch is powered on or reset, at the beginning of switch self test. If this LED is on for a prolonged time, the switch has encountered a fatal hardware failure, or has failed its self test. See chapter 4, "Troubleshooting" for more information.
	Flashing	The Locator LED is used to locate a specific switch in an area full of switches. The LED can be set to be on solid or flash for a specified number of minutes (1-1440). The default is 30 minutes. Use the command "chassislocate".
	Off
PoE (green/orange)	On green	Normal operation. The switch is ready to supply PoE power
	Flashing orange²	One or more ports has experienced a fault condition for PoE delivery. The Fault LED will be flashing simultaneously. If it is a self test failure, the Test LED will be flashing simultaneously. When the switch is put in PoE LED Mode, the Mode LED for the port with the problem will also be flashing simultaneously.
Fan (green/orange) (Switch 2520G-24-PoE only)	On green	The cooling fan is operating normally.
	Flashing orange²	One or more ports has an alert condition for PoE delivery, for example, an oversubscription condition (not enough PoE power available). Only this LED will be flashing, the Fault LED is off. When the switch is put in PoE LED Mode, the Mode LEDs for the ports with the alert condition will also be flashing.
Test (green/orange)	Off	The normal operational state; the switch is not undergoing self test.
	On green	The switch self test and initialization are in progress after the switch has been power cycled or reset. The switch is not operational until this LED goes off. The Test LED also comes on briefly when you “hot swap" a mini-GBIC into the switch; the mini-GBIC is tested when it is hot swapped.
	Flashing orange²	A component of the switch has failed its self test. The switch Fault LED, Test LED, and the failed component LED will flash simultaneously.
