This connection is described under “Connect a Console to the Switch” in chapter 2, “Installing the Switch”. The console can be a PC or workstation running a VT-100 terminal emulator, or a VT-100 terminal.
■ HP Auto-MDIX on all 10/100 twisted-pair ports, and IEEE 802.3ab Auto MDI /MDI-X on all 10/100/1000 twisted-pair ports, meaning that all connections can be made using straight-through twisted-pair cables.
Installing the Switch 2650 The HP Switch 2650 is easy to install. It comes with an accessory kit that includes the brackets for mounting the switch in a standard 19-inch telco rack, in an equipment cabinet, or on a wall, and with rubber feet that can be attached so the switch can be securely located on a horizontal surface.
If your installation requires a different power cord than the one supplied ■ with the switch, be sure to use a power cord displaying the mark of the safety agency that defines the regulations for power cords in your country.
5 cable. The 10/100-Base-TX ports on the Switch 2650 include the “HP Auto-MDIX” feature, which allows you to use either straight-through or crossover twisted-pair cables for connecting to any network devices including end nodes, such as computers, or to other switches, hubs, and routers.
■ orientation relative to other devices and equipment: • In the front of the switch, leave at least 7.6 cm (3 inches) of space for the twisted-pair and fiber-optic cabling. • In the back of the switch, leave at least 3.8 cm (1 1/2 inches) of space for the power cord.
■ HP Procurve Gigabit-LH-LC mini-GBIC (J4860A) C a u t i o n The HP Procurve mini-GBICs are Class 1 laser devices. Avoid direct eye exposure to the beam coming from the transmit port. Installing the mini-GBICs: Hold the mini-GBIC by its sides and gently insert it into either of the slots on the switch until the mini-GBIC clicks into place.
You should disconnect the network cable from the mini-GBIC before removing it from the switch. Depending on when you purchased your HP 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.
Console N o t e The Switch 2650 does not have a power switch. It is powered on when the power cord is connected to the switch and to a power source. For safety, the power outlet should be located near the switch installation.
LED Behavior: During the self test: • Initially, all the switch and port LEDs are on and stay on for most of the duration of the self test. • Most of the LEDs go off and then may come on again during phases of the self test.
Installing the Switch 2650 Installation Procedures 4. Mount the Switch After you have verified that the switch passes self test, you are ready to mount the switch in a stable location. The Switch 2650 can be mounted in these ways: ■...

Horizontal Surface Mounting Place the switch on a table or other horizontal surface. The switch comes with rubber feet in the accessory kit that can be used to help keep the switch from sliding on the surface. Attach the rubber feet to the four corners on the bottom of the switch within the embossed angled lines.
See the table on page 2-5, and appendix B, “Switch Ports and Network Cables”, for the mini-GBIC cabling information. For mini-GBICs 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.
Out-of-band: The Switch 2650 comes with a serial cable for connecting ■ a PC or VT-100 terminal, to be used as a console, directly to the switch. ■ In-Band: Access the console using Telnet from a PC or UNIX station on the network, and a VT-100 terminal emulator.
(CLI) prompt, for example: HP Procurve Switch 2650# If you want to continue with console management of the switch at this time, see chapter 3, “Getting Started With Switch Configuration” for some basic configuration steps. For more detailed information, refer to the Management and Configuration Guide, which is on the Documentation CD-ROM that came with your switch.
Notice that the end node devices are connected to the switch by “straight-through” or “crossover” twisted-pair cables. Either cable type can be used because of the “HP Auto-MDIX” and “IEEE Auto MDI/MDI-X” features on the Switch 2650.
They can also all communicate with the server that is connected to a 1000Base-T port on the switch. Because the Switch 2650 has the “HP Auto-MDIX” and “IEEE Auto MDI/ MDI-X” features, the connections between the switch and the hubs, and between the switch and end nodes or servers can be through category 5 “straight-through”...
The simpler desktop and segment networks shown in the previous two examples can easily be combined and expanded. For example, you could use an HP Procurve Switch 8000M to interconnect each of your smaller switched workgroups to form a larger switched network. All the devices in this network can communicate with each other.
IP address. Up to 16 switches can be connected together in such a “virtual stack”. You identify the 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.
Telnet session, through the switch’s web browser interface, and from an SNMP network management station running a network management program, such as HP TopTools for Hubs & Switches. For a listing of switch features available with and without an IP address, refer to “How IP Addressing Affects Switch Operation”...
The quickest and easiest way to minimally configure the switch for manage- ment 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. Using the method described in the preceding section, connect a terminal device to the switch and display the switch console command (CLI) prompt (the default display).
Recommended; If you set IP Config to Manual, then enter an IP address Note: The IP address and subnet mask assigned for the switch must be compatible with the IP addressing used in your network. For more information on IP addressing, see the Management and Configuration Guide, which is on the Documentation CD-ROM that came with your switch.
PC equipped with Telnet, a web browser interface, or from an SNMP-based network management station using a tool such as HP TopTools for Hubs & Switches. Some basic information on managing your switch is included in the next section.
With your Switch 2650, 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.
HP TopTools for Hubs & Switches needs to be installed on a network management station that is on the subnet.
Troubleshooting This chapter describes how to troubleshoot your HP Procurve Switch 2650. Note that this document describes troubleshooting mostly from a hardware perspective. You can perform more in-depth troubleshooting on the Switch 2650 using the software tools available with the switch, including the full-featured console interface, the built-in web browser interface, and HP TopTools for Hubs &...

Equal-Level Far-End Crosstalk (ELFEXT) and Return Loss. When testing your cabling, be sure to include the patch cables that connect the switch and other end devices to the patch panels on your site. The patch cables are frequently overlooked when testing cable and they must also comply with the cabling standards.
If you experience a high number of transmission errors on the Gigabit-LX ports, usually CRC or FCS errors, you may need to install one of these patch cords between the Gigabit-LX port in your switch and your multimode fiber- optic network cabling, and between the Gigabit-LX transmission device and the network cabling at the other end of the multimode fiber-optic cable run.
Recommended Patch Cords Hewlett-Packard maintains a list of recommended Mode Conditioning Patch Cords that have been tested and verified to operate correctly with the HP Procurve Gigabit-LX Transceiver and HP Procurve Gigabit-LX LC mini-GBIC. The list is on the HP Procurve web site, http://www.hp.com/go/hpprocurve, in the Technical Support section.
Twisted-Pair Cable/Connector Pin-Outs The HP Auto-MDIX Feature: In the default configuration, “Auto”, the fixed 10/100Base-TX ports on the Switch 2650 all automatically detect the type of port on the connected device and operate as either an MDI or MDI-X port, whichever is appropriate.
