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.
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.

Installing a mini-GBIC (SFP) Removing the mini-GBICs Note You should disconnect the network cable from the mini-GBIC before removing it from the switch. Depending on when you purchased your ProCurve mini-GBIC, it may have either of three different release mechanisms: a plastic tab on the bottom of the mini-GBIC, a plastic collar around the mini-GBIC, or a wire bail.
Installing the Switch Installation Procedures For mini-GBIC ports, and in general for all the switch ports, when a network cable from an active network device is connected to the port, the port LED for that port should go on. If the port LED does not go on when the network cable is connected to the port, see “Diagnosing with the LEDs” in chapter 4, “Troubleshooting”. 7.
Installing the Switch Installation Procedures ■ for the Hilgraeve HyperTerminal program, select the “Terminal keys” option for the “Function, arrow, and ctrl keys act as” parameter If you want to operate the console using a different configuration, make sure you change the settings on both the terminal and on the switch so they are compatible. Change the switch settings first, then change the terminal settings, then reboot the switch and reestablish the console session.
Installing the Switch Sample Network Topologies Sample Network Topologies This section shows a few sample network topologies for implementing the 2520G-PoE switches. For more topology information, see the ProCurve networking products Web site, www.hp.com/go/procurve.
Installing the Switch Sample Network Topologies As shown in the above illustration, the IP telephones can be connected in line, that is, between the switch and the end device, in this case a PC. The IP telephones have two ports, one in and one out. Therefore the phone receives voice and power from the switch and the PC can send and receive data through the phone to the switch. The end node devices are connected to the switch by straight-through or crossover twisted-pair cables.
Installing the Switch Sample Network Topologies The 2520G-PoE switches also work well as segment switches. That is, with their high performance, they can be used for interconnecting network segments—simply connect the network devices that form those segments to the 2520G-PoE switches. In the illustration above, 2520G-PoE switches with PCs, printers, and local servers attached, are both connected to a non-PoE switch.
Installing the Switch Sample Network Topologies Stacking the Switch The 2520G-PoE switches can be connected together, through standard network connections, and managed through a single IP address. Up to 16 switches can be connected together in such a “virtual stack”. You identify a 2520G-PoE Switch as the “Commander” and give that switch an IP address. Up to 15 other switches in the network can then easily be configured as Members of the stack and managed through the Commander’s IP address.
3 Configuring the Switch This chapter is a guide for using the console Switch Setup screen to quickly assign an IP (Internet Protocol) address and subnet mask to the switch, set a Manager password, and, optionally, configure other basic features. For more information on using the switch console and the Web browser interface, please see the Management and Configuration Guide, which is on the ProCurve Web site at www.hp.com/go/procurve/manuals.
Configuring the Switch Recommended Minimal Configuration Using the Console Setup Screen The quickest and easiest way to minimally configure the switch for management and password protection in your network is to use a direct console connection to the switch, start a console session, and access the Switch Setup screen. 1. Using the method described in the preceding section, connect a terminal device to the switch and display the switch console command line interface (CLI) prompt (the default display).
Configuring the Switch Recommended Minimal Configuration Here is some information on the fields in the Setup screen.
Configuring the Switch Recommended Minimal Configuration To Recover from a Lost Manager Password: If you cannot start a console session at the manager level because of a lost Manager password, you can clear all passwords and user names by getting physical access to the switch and pressing and holding the Clear button for a full second.
Configuring the Switch Using the IP Address for Remote Switch Management Using the IP Address for Remote Switch Management With your switch, you can use the switch’s IP address to manage the switch from any PC that is on the same subnet as the switch. You can use either a Telnet session or a standard Web browser to manage the switch. Starting a Telnet Session To access the switch through a Telnet session, follow these steps: 1.
4 Troubleshooting This chapter describes how to troubleshoot your ProCurve 2520G-PoE Switches. This document describes troubleshooting mostly from a hardware perspective. You can perform more in-depth troubleshooting on these devices using the software tools available with the switches, including the fullfeatured console interface, the built-in Web browser interface, and ProCurve Manager, the SNMP-based network management tool.
Troubleshooting Basic Troubleshooting Tips Caution Because the 2520G-PoE switches behave in this way (in compliance with the IEEE 802.3 standard), if a device connected to the switch has a fixed configuration at full duplex, the device will not connect correctly to the switch. The result will be high error rates and very inefficient communications between the switch and the device.
Troubleshooting Basic Troubleshooting Tips ■ Check the port configuration. A port on your switch may not be operating as you expect because it has been put into a “blocking” state by Spanning Tree, GVRP (automatic VLANs), or LACP (automatic trunking). (Note that the normal operation of the Spanning Tree, GVRP, and LACP features may put the port in a blocking state.) Or, the port just may have been configured as disabled through software.
Troubleshooting Diagnosing with the LEDs Diagnosing with the LEDs Table 4-1 shows LED patterns on the switch that indicate problem conditions for general switch operation troubleshooting. Table 4-2 shows LED patterns that indicate problem conditions for PoE troubleshooting. LED patterns for General Switch Troubleshooting 1. Check in the table for the LED pattern you see on your switch. 2. Refer to the corresponding diagnostic tip on the next few pages. Table 4-1.
Troubleshooting Diagnosing with the LEDs Diagnostic Tips: Tip Problem Solution ➊ The switch is not plugged into an active AC power source, or the switch’s power supply may have failed. 1. Verify the power cord is plugged into an active power source and to the switch. Make sure these connections are snug. 2. Try power cycling the switch by unplugging and plugging the power cord back in. 3. If the Power LED is still not on, verify the AC power source works by plugging another device into the outlet.
Troubleshooting Diagnosing with the LEDs Tip Problem Solution ➏ The network connection is not working properly. Try the following procedures: • For the indicated port, verify that both ends of the cabling, at the switch and the connected device, are connected properly. • Verify the connected device and switch are both powered on and operating correctly.
Troubleshooting Diagnosing with the LEDs Tip Problem Solution ➐ The port may be improperly configured, or the port may be in a “blocking” state by the normal operation of the Spanning Tree, LACP, or IGMP features. Use the switch console to see if the port is part of a dynamic trunk (through the LACP feature) or to see if Spanning Tree is enabled on the switch, and to see if the port may have been put into a “blocking” state by those features.
Troubleshooting Diagnosing with the LEDs LED Patterns for PoE Troubleshooting If the PoE Status LED is flashing, that indicates a problem with the delivery of PoE power out one or more switch ports. Press the LED Mode button to put the switch into PoE mode and the port LEDs will show which ports are experiencing the problem. The following tables identify the specific problems that are shown by the LEDs. 1. Check in the table for the LED pattern you see on your switch. 2.
Troubleshooting Proactive Networking Proactive Networking The ProCurve 2520G-PoE Switches have built-in management capabilities that proactively help you manage your network including: ■ finding and helping you fix the most common network error conditions (for example, faulty network cabling, and non-standard network topologies) ■ informing you of the problem with clear, easy-to-understand messages ■ recommending network configuration changes to enhance the performance of your network The following i
Troubleshooting Hardware Diagnostic Tests Hardware Diagnostic Tests Testing the Switch by Resetting It If you believe the switch is not operating correctly, you can reset the switch to test its circuitry and operating code. To reset a switch, either: ■ unplug and plug in the power cord (power cycling) ■ press the Reset button on the front of the switch Power cycling the switch and pressing the Reset button both cause the switch to perform its power-on self test.
Troubleshooting Hardware Diagnostic Tests Testing Twisted-Pair Cabling Network cables that fail to provide a link or provide an unreliable link between the switch and the connected network device may not be compatible with the IEEE 802.3 Type 10Base-T, 100Base-TX, or 1000Base-T standards. The twistedpair cables attached to the switch must be compatible with the appropriate standards. To verify your cable is compatible with these standards, use a qualified cable test device.
Troubleshooting Restoring the Factory Default Configuration Restoring the Factory Default Configuration As part of your troubleshooting process on the Switch, it may become necessary to return the switch configuration to the factory default settings. This clears any passwords, clears the console event log, resets the network counters to zero, performs a complete self test, and reboots the switch into its factory default configuration including deleting the IP address, if one is configured.
Troubleshooting Downloading New Switch Software Downloading New Switch Software When product enhancements occur for the 2520G-PoE switches, new software can be downloaded to the switch through several methods, for product enhancements and new features. For more information, see the Management and Configuration Guide. The new switch software would be available on the ProCurve Web site, www.hp.com/go/procurve/software.
