Management ports

Console Ports

There are two serial console port options on the switch, an RJ-45 or Micro USB. These ports are used to connect a console to the switch. You can use either an RJ-45 serial cable or a standard Micro USB cable. (Either option must be ordered separately). The Micro USB connector has precedence for input. If both cables are plugged in, the console output is echoed to both the RJ-45 and the Micro-USB ports. However, the input is only accepted from the Micro-USB port.

For more information on the console connection, see (Optional) Connect a management console on page

47. The console can be a PC or workstation running a VT-100 terminal emulator, or a VT-100 terminal.

LED mode select button and indicator LEDs

The state of the Mode LEDs is controlled by the LED Mode select button. The current view mode is indicated by the Mode LEDs next to the button. Press the button to step from one view mode to the next. See Table 6:

Front of switch status and mode LED behavior on page 12.

Reset and Clear buttons

The Reset and Clear buttons are recessed from the front panel. (This design protects them from being pushed accidentally.) The buttons are accessible through small holes on the top of the front panel. Use pointed objects, such as unbent paper clips, to push them.

The Reset and Clear buttons are used singly or in combination, as follows:

To accomplish this: Do this: This will happen:

Soft reset Press and release the Reset

button.

Hard reset Press and hold the Reset button

for more than 5 seconds (until all LEDs turn on), then release.

2. While continuing to press Clear, release Reset.

The switch operating system is cleared gracefully. (Items such as data transfer completion and temporary error conditions are cleared.) The switch then reboots and runs self-tests.

The switch reboots, similar to a power cycle. A hard reset is used, for example, when the switch CPU is in an unknown state or not responding.

Clears all passwords. Will ash Global Status Green LED, after 5 seconds has expired to indicate that passwords have cleared.

Clears the UID LED.

The switch removes all conguration changes, restores the factory default conguration, and runs self-test.

3. When the Global Status LED begins to fast ash orange (after approximately 5 seconds), release Clear.

NOTE: These buttons are provided for your convenience. If you are concerned with switch security, make sure that the switch is installed in a secure location, such as a locked wiring closet. You can also disable these buttons by using the front-panel-security command. For a description of that command, see the latest Access Security Guide for your switch at https://asp.arubanetworks.com/downloads.

Back of the switches

The back of all the 24-port and 48-port switches are the same. The back of both 8-port and 12-port switches are dierent.

Label Description

1 Ground point

2 AC power connector

3 Cable tie eyelet

5 AC power connector (JL693A)

DC power jack (JL258A and JL692A)

Power connector

The 2930F 12-port, 24-port and 48-port switches do not have a power switch; they are powered on when connected to an active AC power source. The switches automatically adjust to any voltage between 100-127 and 200-240 volts and either 50 or 60 Hz. There are no voltage range settings required.

The Aruba 2930F 8-port switches (JL258A) do not have a power switch; they are powered on when the external AC/DC power adapter is connected to the switch and to a power source. The external AC/DC power adapter supplies 54 volts DC to the switch and automatically adjusts to any AC voltage between 100-240 volts and either 50 or 60 Hz. No voltage range settings are required. Be sure to release the latch on the DC plug before removing the adapter power cord. (See Figure 31: Aruba 2930F 8G (JL258A, JL692A) switch

Switch features

The features of the 2930F switches include:

16 Aruba 2930F Switch Series Installation and Getting Started

Guide

• Combinations of xed 10/100/1000-T and SFP/SFP+ ports, as described under Network ports on page 8.

• Power over Ethernet (PoE+) operation (JL255A, JL256A, JL258A, JL692A, JL693A, JL261A, JL262A, JL263A, JL264A, JL557A, JL558A, JL559A)—The PoE+ switches are IEEE 802.3at standard compliant. They provide up to 30W per port to power IP phones, wireless access points, indoor web cameras, and more. For more information, see the latest version of the HPE Power over Ethernet (PoE/PoE+) Planning and Implementation Guide, available from https://asp.arubanetworks.com/downloads.

The switches support 802.3af and 802.3at standard devices and some prestandard PoE devices. For a list of these devices, see the FAQs (Frequently Asked Questions) for your switch model. PoE is enabled by default. (For more information, see the 2930F Management and Conguration Guide for your switch at https://asp.arubanetworks.com/downloads.

• Plug-and-play networking. All ports are enabled by default. Connect the network cables to active network devices and your switched network is operational.

• Auto MDI/MDI-X on all twisted-pair ports (10/100/1000Base-T), meaning that all connections can be made using straight-through twisted-pair cables. Cross-over cables are not required, although they will also work. The pin operation of each port is automatically adjusted for the attached device: if the switch detects that another switch or hub is connected to the port, it congures the port as MDI; if the switch detects that an end node device is connected to the port, it congures the port as MDI-X. See Cabling and technology information for recommended or required cabling.

• Automatic learning of the network addresses in the 64000-address forwarding table in each switch (with congurable address aging value).

• Automatically negotiated full-duplex operation for the 10/100/1000 RJ-45 ports when connected to other auto-negotiating devices. The SFP/SFP+ ports always operate at full duplex.

• Easy management of the switch through several available interfaces:

◦ Console interface: A full-featured, easy-to-use, VT-100 terminal interface for out-of-band or in-band

switch management.

◦ Web browser interface: An easy-to-use built-in graphical interface that can be accessed from

common web browsers.

◦ Aruba AirWave: A powerful and easy-to-use network operations system that manages wired and

Installation procedures

Procedure

1. Prepare the installation site on page 24.

Ensure the physical environment into which you will be installing the switch is properly prepared. This includes having the correct network cabling ready to connect to the switch and having an appropriate location for the switch. See Installation precautions on page 23 for some installation precautions.

2. Self-test.

Plug the switch into a power source and observe that the LEDs on the switch front panel indicate correct switch operation. When self-test is complete, unplug the switch.

3. Mount the switch on page 27.

The switch can be mounted in a 19-inch telco rack, in an equipment cabinet, or on a horizontal surface. The eight and twelve-port switches (JL258A, JL692A and JL693A) can also be mounted on a wall or under a table.

4. Install or remove SFP/SFP+ transceivers on page 43.

The switch has two or four slots for installing SFP/SFP+ transceivers. Depending on where you install the switch, it may be easier to install the transceivers rst. Transceivers can be hot-swapped—they can be installed or removed while the switch is powered on.

5. Connect the switch to a power source on page 45.

Once the switch is mounted, plug it into the main power source.

6. (Optional) Connect a management console on page 47.

22 Aruba 2930F Switch Series Installation and Getting Started

Guide

You may want to modify the switch conguration. For example, you may want to congure an IP address so it can be managed through a Telnet session or by using a web browser from an SNMP network management station. Conguration changes can be made by using the optionally ordered console cable to connect a PC to the switch console port.

7. Connect the network cables on page 49.

Using the appropriate network cables, connect the network devices to the switch ports.

At this point, your switch is fully installed. See the rest of this chapter if you need more detailed information on any of these installation steps.

Installation precautions

WARNING:

• The rack or cabinet must be adequately secured to prevent it from becoming unstable and/ or falling over.

• Mount devices installed in a rack or cabinet as low as possible, with the heaviest devices at the bottom, and progressively lighter devices installed above.

• For a wall-mounted Aruba 2930F 8G and 12G switches (JL258A, JL692A and JL693A), face the network ports up, that is, away from the oor. Do not wall-mount the switch with the network ports facing down (towards the oor).

Chapter 2 Installing the switch 23

CAUTION:

• When installing the switch, select an AC outlet near the switch to enable easy accessibility in case the switch must be powered o.

• Before connecting the switch to the power source, ensure that the power source circuits are properly grounded.

• Use only approved power cords with your Aruba Networking Product. See the power cord information in the section titled Included parts on page 19 “Included parts” (page 17) of this guide for acceptable power cords that are appropriate for this product. Failure to use approved power cords can result in personal injury and product damage, and may void your product warranty.

• Use only the AC/DC power adapter and power cord (if applicable), supplied with the switch. Use of other adapters or power cords, including those that came with other Aruba products, may result in damage to the equipment.

• If your installation requires a dierent power cord than the one supplied with the switch or power supply, be sure that the cord is adequately sized for the switch current requirements. In addition, be sure to use a power cord displaying the mark of the safety agency that denes the regulations for power cords in your country/region. The mark is your assurance that the power cord can be used safely with the switch and power supply.

• Ensure that the switch does not overload the power circuits, wiring, and over-current protection. To determine the possibility of overloading the supply circuits, add together the ampere ratings of all devices installed on the same circuit as the switch and compare the total with the rating limit for the circuit. The maximum ampere ratings are usually printed on the devices near the AC power connectors.

• Do not install the switch in an environment where the operating ambient temperature might exceed its specication. This caution includes a fully enclosed rack. Ensure the air ow around the sides and back of the switch is not restricted. Leave at least 3 inches (7.6 cm) for cooling for the 24- and 48-port switch models when installed in a fully-enclosed rack.

NOTE: Normal operating temperature for Aruba 2930F 8G and 12G switches (JL258A, JL692A and JL693A) require wider spacing minimums than described earlier for the 24– and 48–port switch models. For rack installation, maintain at least 1U space as a minimum above the product. Also, installing this switch in an enclosed, conned space such as a small bookshelf or unventilated cabinet, is not recommended.

Prepare the installation site

Cabling Infrastructure: Ensure that the cabling infrastructure meets the necessary network specications. See Cabling and technology information for more information.

Installation Location: Before installing the switch, plan its location and orientation relative to other devices

and equipment:

• In the front of the switch, leave at least 3 inches (7.6 cm) of space for the twisted-pair and beroptic cabling.

• In the back of the switch, leave at least 1 1/2 inches (3.8 cm) of space for the power cord.

• On the sides of the switch, leave at least 3 inches (7.6 cm) for cooling.

NOTE: The Aruba 2930F 8G switches (JL258A and JL692A) require more front and back space when used with the optional Aruba JL312A power adapter shelf and Aruba JL311A cable guard. (To attach the cable guard, see the printed instructions included with the cable guard unit.)

Guide

Verify that the switch passes self-test

Before mounting the switch in its network location, rst verify it is working properly by plugging it into a power source and verifying it passes its self-test.

1. For the Aruba 2930F 24-port and 48-port switches, connect the power cord supplied with the switch to the power connector on the back of the switch. Then plug the cord into a properly grounded electrical outlet.

For the Aruba 2930F 8G and 12G switches (JL258A, JL692A and JL693A), connect the AC/DC power cord to the power connector on the back of the switch, Then plug the AC/DC power cord into a nearby properly grounded electrical outlet.

Figure 5: Connecting the power cord on Aruba 2830F switches

Figure 6: Connecting the power cord on Aruba 2930F 8-port switches (JL258A and JL692A)

Chapter 2 Installing the switch 25

NOTE: The 2930F 12-port, 24-port and 48-port switches do not have a power switch. They are powered on when the power cord is connected to the switch and to a power source. For safety, select a power outlet located near the switch installation.

The switch automatically adjusts to any voltage between 100-127 volts or 200-240 volts and either 50 Hz or 60 Hz. There are no voltage range settings required.

The Aruba 2930F 8-port (JL258A, JL692A) switches also have no power switch. They are powered on when the external AC/DC power adapter is connected to the switch and the power adapter cord to a power source. The external AC/DC power adapter automatically adjusts to any voltage between 100-240 volts and either 50 Hz or 60 Hz. Be sure to release the latch on the DC plug before removing the adapter power cord. (See Figure 31: Aruba

2930F 8G (JL258A, JL692A) switch power plug latch on page 46.)

2. Check the LEDs on the switch as described in this example.

Figure 7: Example of LEDs on the 2930F switches

Table 9: Example of LEDs on the 2930F switches labels and descriptions

Label Description

1 SFP/SFP+ port LEDs

2 RJ-45 port LEDs

3 Global Status and UID LEDs

4 Mode LEDs

When the switch is powered on, it performs its diagnostic self-test and initialization. This boot process, depending on switch model and conguration, takes approximately 1-2 minutes to complete.

LED behavior:

During the switch boot:

• The Global Status, UID, other status, and mode LEDs, will initially turn green, and bi-color LEDs will change to orange, then back to green.

• The Global Status LED will start blinking green, indicating that the switch is going through its self-test and will continue to blink green until the switch is fully booted.

• The port LEDs will initially turn green, then turn orange, turn back to green, and then may blink on and o during phases of the boot.

When the switch boots successfully, the following LEDs display:

• Global Status will be solid green.

• UID LED is o.

26 Aruba 2930F Switch Series Installation and Getting Started

Guide

• Other status LEDs may be on or o depending on the switch conguration and the hardware installed.

• The port LEDs go into their normal operational mode:

◦ If the ports are connected to active network devices, the port LED may be on and behaves according

to the LED mode selected. In the default LED mode (Activity/Link), the LED should show half-bright green to indicate link and be ickering full-bright green to show network trac.

◦ If the ports are not connected to active network devices, the port LED will stay o.

If the LED display is dierent than what is described above, especially if the Global Status LED continues to blink green for more than 120 seconds or blinks orange continually, the switch boot has not completed correctly. Refer to Troubleshooting on page 58 for diagnostic help.

Install or remove SFP/SFP+ transceivers

You can install or remove a transceiver from an SFP/SFP+ slot without having to power o the switch.

Chapter 2 Installing the switch 43

NOTE:

• The transceivers operate only at full duplex. Half duplex operation is not supported.

• Ensure the network cable is NOT connected when you install or remove a transceiver.

CAUTION: Use only supported genuine Aruba SFP/SFP+ transceivers with your switch. NonAruba SFP/SFP+ transceivers are not supported, and their use may result in product malfunction. Should you require additional transceivers, contact your Aruba sales representative or an authorized reseller.

Installing the transceivers

Hold the transceiver by its sides and gently insert it into either of the slots on the switch until it clicks into place. When a transceiver is inserted, the switch authenticates it. This can take 1-3 seconds, with the worst case being 5 seconds. If the transceiver is removed before the authentication completes, a self test failure is reported.

WARNING: The Aruba transceivers are Class 1 laser devices. Avoid direct eye exposure to the beam coming from the transmit port.

NOTE: Always disconnect the network cable from a transceiver before installing it in the switch.

Figure 29: Installing a transceiver

Removing the transceiver:

NOTE: Always disconnect the network cable from the transceiver before removing it from the

switch.

Depending on when the transceiver was purchased, it may have either of three dierent release mechanisms:

Guide

(Optional) Connect a management console

The switch has a full-featured, easy-to-use console interface for performing switch management tasks including:

• Monitor switch and port status and observe network activity statistics.

• Modify the switch conguration to optimize switch performance, enhance network trac control, and improve network security.

• Read the event log and access diagnostic tools to help in troubleshooting.

• Download new software to the switch.

• Add passwords to control access to the switch from the console, web browser interface, and network management stations.

The console can be accessed through these methods:

• Out of band: Connect an Aruba X2C2 RJ45 to DB9 Console Cable (sold separately: JL448A) to the switch’s RJ-45 Console Port and a workstation with terminal emulation software.

There is also the option of using a USB cable (not supplied) to connect the Micro USB Console Port on the switch to a PC. To use the USB Console Port, you must rst download a USB driver to the PC.

NOTE: USB Console Port Driver Download. When using the Micro USB Console Port, the connected PC rst requires “virtual COM port” USB drivers to be installed. USB drivers are available for Windows XP, Windows Vista, and Windows 7.

USB console drivers are available at https://asp.arubanetworks.com. Type a product name (e.g. 2930F) or product number in the Auto Search textbox. Select one of the switches from the drop-down list. Click the Display selected button. From the options that appear, select Software downloads (on the right-hand side). Download the “USB Console Port Drivers and Information.”

You cannot use both the RJ-45 Console Port and USB Console Port at the same time. When the USB Console Port is connected to a live PC, it has priority over the RJ-45 Console Port.

By default, the RJ-45 console port is active (accepts input). To activate the USB console port, connect it to a live PC. If the USB console session closes because of the inactivity timer, the RJ-45 console port becomes active again to allow remote access through a terminal server. To reactivate the USB console port, unplug it, then reconnect it to a live PC.

• In-Band: Access the console using Telnet from a PC or UNIX station on the network, and a VT-100 terminal emulator. This method requires that you rst congure the switch with an IP address and subnet mask by using either out-of-band console access or through DHCP/Bootp. For more information on IP addressing and on starting a Telnet session, see Getting started with switch conguration on page 53. The switches can simultaneously support one out-of-band console session through a Console Port and in-band Telnet console sessions.

The switches can simultaneously support one out-of-band console session through a Console Port and inband Telnet console sessions.

Terminal conguration

To connect a console to the switch, congure the PC terminal emulator as a DEC VT-100 (ANSI) terminal or use a VT-100 terminal, and congure either one to operate with these settings:

Chapter 2 Installing the switch 47

• Any baud rate from 1200 to 115200 (the switch senses the speed).

• Eight data bits, one stop bit, no parity, and ow control set to o.

• For the Windows Terminal program, also disable (clear) the “Use Function, Arrow, and Ctrl Keys for Windows” option.

• 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 dierent conguration, change the settings on both the terminal and on the switch so they are compatible. Change the switch settings rst, then change the terminal settings, then reboot the switch and re-establish the console session.

Direct console access

To connect a console to the switch, follow these steps:

1. Connect the PC or terminal to the switch Console Port using the console cable included with the switch. (If your PC or terminal has a 25-pin serial connector, rst attach a 9-pin to 25-pin straight-through adapter at one end of the console cable.)

Alternatively, connect the PC to the switch Micro USB Console Port using a USB cable (not supplied). Use a USB 2.0 high-speed cable with male type A (4-pin) to male micro-B (5-pin) connectors. The maximum allowable length is 5 meters.

To use the USB Console Port, you must rst download a USB driver to the PC.

Figure 33: Connecting a console cable

2. Turn on the terminal or PC power and, if using a PC, start the PC terminal program.

3. Press [Enter] two or three times and you will see the copyright page and the message “Press any key to

continue”. Press a key, and you will then see the switch console command (CLI) prompt, for example:

Sample network topologies

This section shows some sample network topologies in which the switch is implemented.

As a desktop switch implementing PoE

The switch is designed to be used primarily as a desktop switch to which end nodes, printers, and other peripherals and servers are directly connected, as shown in the following illustration. 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 IEEE Auto MDI/MDI-X features on the switch.

Figure 37: Basic desktop conguration

This illustration is an example of the switch being congured to supply PoE/PoE+ power to end devices such as IP telephones and wireless access points (WAPs).

As shown in this gure, 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 in this illustration 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. Either cable type can be used because of the IEEE Auto MDI/MDI-X features on the switch.

Chapter 2 Installing the switch 51

As a segment switch implementing PoE

Figure 38: Segment network conguration with PoE switches

The switch also works well as a segment switch. That is, with its high performance, it can be used for interconnecting network segments. Simply connect the network devices that form those segments to the switch or you can also connect other switches.

In the illustration above, two 2930F PoE+ switches with PCs, printers, and local servers attached, are both connected to a switch. The devices attached to the two 2930F PoE+ switches can now communicate with each other through the non-PoE switch. They can also all communicate with the server that is connected to a 1000Base-T port on the switch.

As shown in the illustration above, the IP telephones have been inserted in between the 2930F PoE+ switch and the PCs, and a wireless access point (WAP) has been connected to the 2930F PoE+ switch. Only devices directly connected to PoE switches can receive PoE power. Devices connected to the non-PoE switch cannot receive PoE power.

Because the 2930F switches have the Auto-MDIX feature, the connections between the switches and end nodes or servers can be through category 5 straight-through or crossover twisted-pair cable. If the connection is 10 Mbps only, then Category 3 or 4 cable can also be used. In all cases, the device ports must be congured to auto negotiate the link characteristics for this feature to work.

The switch, in turn, can be connected to a network backbone through ber-optic cabling connected to a Gigabit or 10 Gigabit transceiver installed in the switch. Now, all the devices on these network segments can access other network resources that are connected elsewhere on the network backbone.

Chapter 3

Getting started with switch conguration

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. You can also set a Manager password and, optionally, congure other basic features.

For more information on using the switch console, see the Basic Operation Guide and the Management and Conguration Guide for your switch model at https://asp.arubanetworks.com/downloads.

For information on the Aruba IMC (Intelligent Management Center), contact your Aruba representative.

Recommended minimal conguration

In the factory default conguration, the switch has no IP (Internet Protocol) address and subnet mask, and no passwords. In this state, it can be managed only through a direct console connection. To manage the switch through in-band (networked) access, congure the switch with an IP address and subnet mask compatible with your network.

Also, congure a Manager password to control access privileges from the console and web browser interface. Other parameters in the Switch Setup screen can be left at either their default settings or settings you manually enter.

Many other features can be congured through the switch console interface to optimize performance, to enhance your control of the network trac, and to improve network security. Once an IP address has been congured on the switch, these features can be accessed more conveniently through a remote Telnet session, through the switch web browser interface, and from an SNMP network management station running a network management program. For a list of switch features available with and without an IP address, see the latest version of the Aruba Basic Operation Guide for ArubaOS-Switch at https://

asp.arubanetworks.com/downloads.

NOTE: By default, the switch is congured to acquire an IP address conguration from a DHCP

or Bootp server. To use DHCP/Bootp instead of the manual method described in this chapter, see “DHCP/Bootp Operation” in the latest version of the Aruba Basic Operation Guide for

ArubaOS-Switch at https://asp.arubanetworks.com/downloads.

Using the console setup screen

The quickest and easiest way to minimally congure 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.

Procedure

1. Using the method described in Terminal conguration on page 47, connect a terminal device to the

switch and display the switch console command line interface (CLI) prompt (the default display).

The CLI prompt appears, for example:

Aruba-2930F-24G-4SFPP#

2. At the prompt, enter the setup command to display the Switch Setup screen.

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 more than 5 seconds. See Reset and Clear buttons on page 15.

Using the IP address for remote switch management

The IP address of a switch can be used to manage the switch from any PC on the same or on a subnet as the switch. In a networked connection, you can use a Telnet session or a standard web browser to manage the switch.

dierent

Starting a Telnet session

To access the switch through a Telnet session, follow these steps:

Procedure

1. Make sure the switch is congured with an IP address and that the switch is reachable from the PC that is

running the Telnet session (for example, by using a Ping command to the switch’s IP address).

2. Start the Telnet program on a PC that is on the same subnet as the switch and connect to the switch’s IP address.

3. You will see the copyright page and the message “Press any key to continue”. Press a key, and you will then see the switch console command (CLI) prompt, for example: Aruba-2930F-24G-4SFPP# Enter help or ? to see a list of commands that can be executed at the prompt.

Troubleshooting

This chapter describes how to troubleshoot your switch, primarily from a hardware perspective. You can perform more in-depth troubleshooting on the switch using the software tools available with the switch. Included are the console interface and the built-in web browser interface. Other tools include AirWave and the Intelligent Management Center (IMC, which is the SNMP-based network management tool). For more information, see the “Troubleshooting” chapter in the latest version of the Aruba 2930F / 2930M Management and Conguration Guide for ArubaOS-Switch, available on the https://asp.arubanetworks.com/downloads website.

This chapter describes the following:

• Basic troubleshooting tips

• Diagnosing with the LEDs

• Proactive networking

• Hardware diagnostic tests

• Restoring the factory default conguration

• Downloading new switch software

Basic troubleshooting tips

Most problems are caused by the following situations. Check for these items rst when starting your troubleshooting:

• Connecting to devices that have a xed full-duplex conguration: The RJ-45 ports are congured as “Auto”. That is, when connecting to attached devices, the switch operates in either half duplex or full duplex to determine the link speed and the communication mode:

◦ If the connected device is also congured to Auto, the switch will automatically negotiate both link

speed and communication mode.

◦ If the connected device has a xed conguration, for example 100 Mbps, at half or full duplex, the

switch will automatically sense the link speed, but will default to a communication mode of half duplex.

Because the switch behaves in this way (in compliance with the IEEE 802.3 standard), if a device connected to the switch has a xed conguration at full duplex, the device will not connect correctly to the switch. The result will be high error rates and inecient communications between the switch and the device.

Make sure that all the devices connected to the switch are congured to auto negotiate, or are congured to speed and duplex settings matching the settings congured on the corresponding switch port.

• Improper network topologies: It is important to make sure that you have a valid network topology. Common topology faults include excessive cable length and excessive repeater delays between end nodes. If you have network problems after recent changes to the network, change back to the previous topology. If you no longer experience the problems, the new topology is probably at fault. Sample topologies are shown at the end of chapter 2 in this book.

58 Aruba 2930F Switch Series Installation and Getting Started

Guide

In addition, make sure that your network topology contains no data path loops. Between any two end nodes, only one active cabling path is allowed at any time. Data path loops can cause broadcast storms that will severely impact your network performance.

For your switch, if you want to build redundant paths between important nodes in your network to provide some fault tolerance, enable Spanning Tree Protocol support on the switch. This support ensures that only one of the redundant paths is active at any time, thus avoiding data path loops. Spanning Tree can be enabled through the switch console or the web browser interface. For more information on Spanning Tree, see the Advanced Trac Management Guide for your switch at https:// asp.arubanetworks.com/downloads.

The switch also supports Trunking, which allows multiple network cables to be used for a single network connection without causing a data path loop. For more on Trunking, see the Management and Conguration Guide, also at https://asp.arubanetworks.com/downloads.

• Faulty or loose cables: Look for loose or faulty connections. If they appear to be OK, make sure that the connections are snug. If that does not correct the problem, try a dierent cable.

• Nonstandard cables: Nonstandard and incorrectly wired cables may cause network collisions and other network problems, and can seriously impair network performance. A category 5 or greater cable tester is a recommended tool for every 100Base-TX and 1000Base-T network installation.

• Check the port conguration: A port on your switch may not be operating as expected because it is administratively disabled in the conguration. It may also be placed into a “blocking” state by a protocol operating on the port (dynamic VLANs), or LACP (dynamic trunking). For example, the normal operation of the spanning tree, GVRP, LACP, and other features may put the port in a blocking state.

Use the switch console to determine the port conguration and verify that there is not an improper or undesired conguration of any of the switch features that may be aecting the port. For more information, see the Management and Conguration Guide for your switch at https://

asp.arubanetworks.com/downloads.

Tip Problem Solution

1 The switch is not plugged into an active AC power

source, or the switch power supply may have failed.

2 A switch hardware failure has occurred. All the

LEDs will stay on indenitely.

1. Verify that the power cord is plugged into an active power source and to the switch. Make sure that these connections are snug.

2. Try power cycling the switch by unplugging and plugging the power cord back in.

3. If the Global Status LED is still not on, verify that the AC power source works by plugging another device into the outlet. Or try plugging the switch into a dierent outlet or try a dierent power cord.

If the power source and power cord are OK and this condition persists, the switch power supply may have failed. To get assistance, call your Aruba authorized network reseller, or use the electronic support services from Aruba to get assistance.

Try power cycling the switch. If the fault indication reoccurs, the switch may have failed. To get assistance, either call your Aruba authorized network reseller, or use the electronic support services from Aruba.

3 The switch has experienced a software failure

during self-test, or one of the switch cooling fans may have failed.

1. Try resetting the switch by pressing the Reset button on the front of the switch, or by power cycling the switch.

2. If the fault indication reoccurs, attach a console to the switch and congure it to operate at 9600 baud. Then, reset the switch. Messages should appear on the console screen and in the console log identifying the error condition. You can view the console log at that point by selecting it from the console Main Menu or by typing show log at the Manager command prompt (#).

The error may indicate that one of the fans has failed. In switches with multiple fans, the switch may continue to operate under this condition if the ambient temperature does not exceed normal room temperature, but for best operation, replace the switch.

If necessary to resolve the problem, contact your Aruba authorized network reseller, or use the electronic support services from Aruba to get assistance.

4 The network port for which the LED is blinking

has experienced a self-test or initialization failure.

Try power cycling the switch. If the fault indication reoccurs, the switch port may have failed. Call your Aruba authorized network reseller, or use the electronic support services from Aruba to get assistance.

If the port is an SFP, verify it is one of the SFPs supported by the switch. Unsupported SFPs will be identied with this fault condition. The SFPs are also tested when they are “hot-swapped”— installed or changed while the switch is powered on.

To verify that the port has failed, try removing and reinstalling the SFP without powering o the switch. If the port fault indication reoccurs, you will have to replace the SFP. Check the event log to see why the SFP failed.

Tip Problem Solution

5 The network connection is not working properly.

Try the following procedures:

• For the indicated port, verify 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.

• Verify that you have used the correct cable type for the connection:

◦ For twisted-pair connections to the xed

10/100/1000 ports, if the port is congured to “Auto” (auto negotiate), either straightthrough or crossover cables can be used because of the switch “Auto-MDIX” feature and the Auto MDI/MDI-X feature of the 10/100/1000-T port.

NOTE: If the switch port conguration is changed to one of the xed conguration options (for example, 100 Mbps/Full Duplex), then the port operates as MDI-X only and you must use the correct type of cable for the connection. In general, for connecting an end node (MDI port) to the switch, use straight-through cable; for connecting to MDI-X ports on hubs, other switches, and routers, use crossover cable.

◦ For ber-optic connections, verify that the

transmit port on the switch is connected to the receive port on the connected device, and the switch receive port is connected to the transmit port on the connected device.

• For 1000Base-T connections, verify that the network cabling complies with the IEEE

802.3ab standard. Install the cable according to the ANSI/TIA/EIA-568-A-5 specications. Ensure that the cable testing complies with the stated limitations for Attenuation, NearEnd Crosstalk, Far-End Crosstalk, Equal-Level Far-End Crosstalk (ELFEXT), Multiple Disturber ELFEXT, and Return Loss.

The cable verication process must include all patch cables from any end devices, including

Guide

Tip Problem Solution

the switch, to any patch panels in the cabling path.

• Verify that the port has not been disabled through a switch conguration change.

You can use the console interface, or, if you have congured an IP address on the switch, use the web browser interface or IMC (Intelligent Management Center) network management software to determine the state of the port and re-enable the port if necessary.

• Verify that the switch port conguration matches the conguration of the attached device. For example, if the switch port is congured as “Auto”, the port on the attached device also MUST be congured as “Auto”. Depending on the port type, twisted-pair or ber-optic, if the congurations don’t match, the results could be a very unreliable connection, or no link at all.

• If the other procedures do not resolve the problem, try using a dierent port or a dierent cable.

6 The port or remote link partner may be

improperly congured, or the port may be in a “blocking” state by the normal operation of protocols, such as Spanning Tree, LACP, or GVRP features.

• You must ensure that the device at the other end of the connection indicates a good link to the switch. If it does not, the problem may be with the cabling between the devices, the connectors on the cable, or the conguration of the device on the remote end of the cable.

• 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. The show lacp command displays the port status for the LACP feature; the show Spanning Tree command displays the port status for Spanning Tree.

Check the Port Status using the show interfaces command to conrm whether the port is congured as “disabled”.

Other switch features that may aect the port operation include VLANs and IGMP. Use the switch console to see how the port is congured for these features.

Ensure also, that the device at the other end of the connection is indicating a good link to the switch. If it is not, the problem may be with the cabling between the devices or the connectors on the cable.

LED patterns for PoE troubleshooting

If the PoE Status LED is ashing, 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 specic problems that are shown by the LEDs.

1. Check in the table for the LED pattern you see on your switch.

Proactive networking

The 2930F switches have built-in management capabilities that proactively help you manage your network, they include:

64 Aruba 2930F Switch Series Installation and Getting Started

Guide

• Finding and helping you x the most common network error conditions (for example, faulty network cabling, and nonstandard network topologies).

• Informing you of the problem with clear, easy-to-understand messages.

• Recommending network conguration changes to enhance the performance of your network.

The following interfaces provide tests, indicators, and an event log that can be used to monitor the switch and its network connections:

• Aruba AirWave: A powerful and easy-to-use network operations system that manages wired and wireless infrastructures.

• IMC (Intelligent Management Center): an SNMP-based network management tool that is included with your switch. Free trials of IMC (Intelligent Management Center) can be downloaded at http:// www.hpe.com/networking/imc.

• A graphical web browser interface that you can use to manage your switch from a PC running a supported web browser such as Microsoft Internet Explorer or Firefox.

• A full-featured console interface. To access the interface, connect a standard terminal or PC running a terminal emulator to the switch console port. Use an Aruba X2C2 RJ45 to DB9 Console Cable (JL448A) (sold separately). The console command line interface is also accessible through a Telnet or SSH connection.

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, try any of the following:

• Unplug and plug in the power cord (power cycling).

• Press the Reset button on the front of the switch.

• Reboot the switch via the management console’s boot system command.

Power cycling the switch and pressing the Reset button both cause the switch to perform its power-on self test, which almost always will resolve any temporary operational problems. These reset processes also cause any network

trac counters to be reset to zero, and cause the System Up Time timer to reset to zero.

Checking the switch LEDs

See Diagnosing with the LEDs on page 59 for information on interpreting the LED patterns and LED behaviors.

Checking console messages

Useful diagnostic messages may be displayed on the console screen when you reset a switch. Connect a PC running a VT-100 terminal emulator program or a standard VT-100 terminal to the switch’s console port and congure it to run at 9600 baud, and with the other terminal communication settings shown in Terminal conguration on page 47.

When you reset the switch, note the messages that are displayed. Additionally, you can check the switch event log, which can be accessed from the console using the show log command, or from the console main menu.

Chapter 4 Troubleshooting 65

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 twisted-pair cables attached to the switch must be compatible with the appropriate standards. To verify your cable is compatible with these standards, use a

qualied cable test device.

Testing switch-to-device network communications

The following communication tests can verify that the network is operating correctly between the switch and any connected device that can respond correctly to the communication test.

• Link Test: A physical layer test that sends IEEE 802.2 test packets to any device identied by its MAC address.

• Ping Test: A network layer test used on IP networks that sends test packets to any device identied by its IP address.

These tests can be performed through the switch console interface. Use a terminal connected directly to the switch or through a Telnet connection, or from the switch web browser interface. For more information, see the Management and Conguration Guide for your switch at http://www.hpe.com/support/manuals.

These tests can also be performed from an SNMP network management station running a program that can manage the switch. Examples include IMC (Intelligent Management Center) and AirWave.

Testing end-to-end network communications

Both the switch and the cabling can be tested by running an end-to-end communications test. This is a test that sends known data from one network device to another through the switch. For example, if you have two PCs on the network that have LAN adapters between which you can run a link-level test or Ping test through the switch, you can use this test to verify that the entire communication path between the two PCs is functioning correctly. See your LAN adapter documentation for more information on running a link test or Ping test.

Restoring the factory default conguration

As part of your troubleshooting process on the switch, it may become necessary to return the switch conguration to the factory default settings. This process momentarily interrupts the switch operation, 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 conguration, including deleting the IP address, if one is congured.

NOTE: This process removes all switch conguration changes made from the factory default settings. This operation includes, for example, conguration of VLANs, spanning tree, trunks, and stacking. Returning the conguration of these features to their factory default settings (usually disabling them) may result in network connectivity issues.

If the switch has a valid conguration, and you are restoring the factory default settings for a reason other than conguration problems, save the switch conguration prior to performing the factory default reset. After the reset and resolution of the original problem, you can restore the saved conguration to the switch. For information on saving and restoring the

conguration, see the latest edition of the Basic Operation Guide for your switch at https:// asp.arubanetworks.com/downloads.

You can restore the factory default conguration either on the switch console or on the switch itself.

66 Aruba 2930F Switch Series Installation and Getting Started

Guide

To restore the factory default conguration using the console, execute the erase startup-config command from the console command prompt. For stacked switches, reset stacking congurations to factory defaults by executing the stacking factory-reset command.

To execute the factory default reset on the switch, perform these steps:

Procedure

1. Using pointed objects, simultaneously press both the Reset and Clear buttons on the front of the switch.

2. Continue to press the Clear button while releasing the Reset button.

3. When the Global Status LED begins to fast ash orange (after approximately 5 seconds), release the Clear

button.

The switch will then complete its boot process and begin operating with its conguration restored to the factory default settings.

Multimode ber 62.5/125 μm or 50/125 μm (core/

cladding) diameter, low metal content, graded index ber-optic cables, complying with the ITU-T G.651 and ISO/IEC 793-2 Type A1b or A1a standards respectively.

Single mode ber 9/125 μm (core/cladding)

diameter, low metal content ber- optic cables, complying with the ITU-T G.652 and ISO/IEC 793-2 Type B1 standards.

A mode conditioning patch cord may be needed for some Gigabit-LX and 10-Gigabit LRM installations.

Note on 1000BASE-T cable requirements

The Category 5 networking cables that work for 100BASE-TX connections should also work for 1000BASE-T, as long as all four-pairs are connected. But, for the most robust connections, you should use cabling that complies with the Category 5e specications, as described in Addendum 5 to the TIA-568-A standard (ANSI/TIA/EIA-568-A-5).

Because of the increased speed provided by 1000BASE-T (Gigabit-T), network cable quality is more important than for either 10BASE-T or 100BASE-TX. Cabling plants being used to carry 1000BASE-T networking must comply with the IEEE 802.3ab standards. In particular, the cabling must pass tests for Attenuation, Near-End Crosstalk (NEXT), and Far-End Crosstalk (FEXT). Additionally, unlike the cables for 100BASE-TX, the 1000BASET cables must pass tests for 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.

Mode conditioning patch cord

The following information applies to installations in which multimode ber-optic cables are connected to a Gigabit-LX port. Multimode cable has a design characteristic called “Dierential Mode Delay”, which requires the transmission signals be “conditioned” to compensate for the cable design and thus prevent resulting transmission errors.

Under certain circumstances, depending on the cable used and the lengths of the cable runs, an external Mode Conditioning Patch Cord may need to be installed between the Gigait-LX transmitting device and the multimode network cable to provide the transmission conditioning. If you experience a high number of transmission errors on those ports, usually CRC or FCS errors, you may need to install one of these patch cords between the ber-optic port in your switch and your multimode ber-optic network cabling, at both ends of the network link.

The patch cord consists of a short length of single mode ber cable coupled to graded-index multimode

ber cable on the transmit side, and only multimode cable on the receive side. The section of single mode ber is connected in such a way that it minimizes the eects of the dierential mode delay in the multimode

cable.

NOTE: Most of the time, if you are using good quality graded-index multimode ber cable that adheres to the standards listed in this section, there should not be a need to use mode conditioning patch cords in your network. This is especially true if the ber runs in your network are relatively short.

Installing the patch cord

As shown in the illustration below, connect the patch cord to the Hewlett Packard Enterprise transceiver with the section of single mode ber plugged in to the Tx (transmit) port. Then, connect the other end of the patch cord to your network cabling patch panel, or directly to the network multimode ber.

74 Aruba 2930F Switch Series Installation and Getting Started

Guide

If you connect the patch cord directly to the network cabling, you may need to install a female-to-female adapter to allow the cables to be connected together.

Figure 40: Connecting a mode conditioning patch cord for Gigabit-LX

Be sure to purchase a patch cord that has appropriate connectors on each end, and has multimode bers that match the characteristics of the multimode ber in your network. Most important, the core diameter of the multimode patch cord must match the core diameter of the multimode cable infrastructure (either 50 or

62.5 microns).

Twisted-pair cable/connector pinouts

Auto-MDIX feature

In the default conguration, “Auto”, the xed 10/100/1000BASE-T ports on the Aruba 2930F Switches all automatically detect the type of port on the connected device and operate as either an MDI or MDI-X port, whichever is appropriate. So for any connection, a straight-through twisted-pair cable can be used. You no longer have to use crossover cables, although crossover cables can also be used for any of the connections. (The 10/100/1000-T ports support the IEEE 802.3ab standard, which includes the “Auto-MDIX” feature.)

If you connect a 2930F switch twisted-pair port to another switch or hub, which typically have MDI-X ports, the 2930F port automatically operates as an MDI port. If you connect it to an end node, such as a server or PC, which typically have MDI ports, the 2930F switch port operates as an MDI-X port. In all cases, you can use standard straight-through cables or crossover cables.

If you use a correctly-wired crossover cable, though, the switch will still be able to automatically detect the MDI/MDI-X operation and link correctly to the connected device.

NOTE: Using xed congurations

If the port conguration is changed to any of the xed congurations though, for example 100 Mbps/full duplex, the port operates as MDI-X only and the correct cable type must be used: for connections to MDI ports, such as end nodes, use a straight-through cable; for connections to MDI-X ports, such as on hubs and other switches, use a crossover cable.

Chapter 6 Cabling and technology information 75

Other wiring rules

• All twisted-pair wires used for 10 Mbps, and 100 Mbps operation must be twisted through the entire length of the cable. The wiring sequence must conform to EIA/TIA 568-B (not USOC).

• For 1000BASE-T connections, all four pairs of wires in the cable must be available for data transmission.

• For 10 Mbps connections to the ports, you can use Category 3, 4, or 5 unshielded twisted-pair cable, as supported by the IEEE 802.3 Type 10Base-T standard.

• For 100 Mbps connections to the ports, use 100-ohm Category 5 UTP or STP cable only, as supported by the IEEE 802.3u Type 100BASE-TX standard.

• For 1000 Mbps connections, 100-ohm Category 5e or better cabling is recommended.

• To provide Power over Ethernet to the access point, all 4 pairs must be connected for any network cable attached to this port; the cable must meet ISO/DIS 11801 Class D requirements and IEEE 802.3af requirements.

Straight-through twisted-pair cable for 10 Mbps or 100 Mbps network connections

Because of the Aruba Auto-MDIX operation of the 10/100 ports on the switch, for all network connections, to PCs, servers or other end nodes, or to hubs or other switches, you can use straight-through cables.

If any of these ports are given a MDI-X ports, and straight-through cables must be then used for connections to PC NICs and other MDI ports.

Crossover twisted-pair cable for 10 Mbps or 100 Mbps network connection

The Auto-MDIX operation of the 10/100 ports on the switch also allows you to use crossover cables for all network connections, to PCs, servers or other end nodes, or to hubs or other switches.

If any of these ports are given a xed conguration, for example 100 Mbps/Full Duplex, the ports operate as MDI-X ports, and crossover cables must be then used for connections to hubs or switches or other MDI-X network devices.
