1 Introducing the Switch The HP ProCurve 2520G-PoE Switches are multiport switches that can be used to build high-performance switched workgroup networks. These switches are store-and-forward devices that offer low latency for high-speed networking. The 2520G-PoE switches also support Power over Ethernet (PoE) technologies. HP ProCurve 2520G-8-PoE Switch (J9298A) HP ProCurve 2520G-24-PoE Switch (J9299A) Throughout this manual, these switches will be referred to as the Switch 2520G-8-PoE and

Introducing the Switch Dual-personality ports use either the 10/100/1000Base-T RJ-45 connector, or a supported ProCurve mini-GBIC (Small Form Factor Pluggable (SFP)) for fiber-optic connection. By default, the RJ-45 connectors are enabled. These switches can be directly connected to computers, printers, and servers to provide dedicated bandwidth to those devices, and you can build a switched network infrastructure by connecting the switch to hubs, other switches, or routers. In addition, t

Introducing the Switch Front of the Switch LEDs On the 2520G-PoE switches, there are three groupings of LEDs: ■ switch status LEDs (Table 1-2) ■ port LEDs (Table 1-3) ■ Port LED Mode indicator LEDs (near the selector button) (Table 1-4) Table 1-2. Switch Status LEDs Switch LEDs State Meaning Power On The internal power supply is working properly. (green) Off No power connection. The switch is NOT receiving power. Fault Off The normal state; indicates there are no fault conditions on the switch.

Introducing the Switch Front of the Switch Switch LEDs State Meaning Test Off The normal operational state; the switch is not undergoing self test. (green/orange) 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 A component of the swit

Introducing the Switch Front of the Switch Port LEDs The port LEDs provide information about the individual switch ports. Table 1-3. Port LEDs Switch LEDs State Meaning Port LEDs 2 Link On The port is enabled and receiving a link indication from the connected device. In PoE mode, indicates that the port is configured to enable PoE (green) power delivery to the connected device.

Introducing the Switch Front of the Switch LED Mode Select Button and Indicator LEDs To optimize the amount of information that can be displayed for each of the switch ports in the limited space available, the 2520G-PoE switches use multiple-display LEDs for each port. Link LED Mode LED The 2520G-PoE switches, have two LEDs per port. The Link status is always shown by the Link LED. The operation of the Mode LED is controlled by the LED Mode select button, and the current setting is i
