Power supplies

The Aruba 8320 switch does not have a power switch; it is powered on when at least one installed power supply is connected to an active AC power source. The power supplies 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.

Never insert or remove a power supply while the power cord is connected. Verify that cord has been disconnected from the power supply before installation or removal.

The Aruba 8320 switch power supplies adapt electrical power for use with the switch. The chassis has two slots that can hold individual power supplies to support load sharing, redundancy, and fault tolerance. One power supply is available for use with the Aruba 8320 switch:

Aruba X371 400W 100-240VAC Power Supply (JL480A)

12 Aruba 8320 Switch Installation and Getting Started Guide

The Aruba 8320 switch is shipped with two hot-swappable, field-replaceable, AC power supplies. Each power supply has a country-specific power cord for connection to an AC power outlet. The switch can operate with one active power supply.

On amber The power supply is in standby

mode with AC power connected. Or, if the Global Status LED is also flashing, indicates a failure.

Off AC power is not connected to

the power supply or it is in protection mode due to a voltage, current, thermal, or short-circuit condition.

Load Sharing

Load sharing occurs when two power supplies are installed in the switch and turned on. Load sharing divides the total power load of the switch among both power supplies. Since the power supplies work together, the effective power capacity of the switch is increased with the additional power supply.

Redundancy

With power redundancy, the Aruba 8320 switch can continue normal operation even when one power supply fails or is powered off. When two power supplies are installed, if one becomes unavailable (fails, or is powered off or removed) the remaining power supply provides full power for the device.

Hot Swapping

Hot swapping allows you to replace one failed power supply while the other provides full power. This makes it unnecessary to shut down the switch during the replacement procedure.

Fan Trays

The Aruba 8320 switch is equipped with five field-replaceable, hot-swappable fan trays. Each fan tray features individual fans that pull air through the chassis from the front through to the rear. The switch can tolerate the failure of a single fan tray while maintaining a safe operating temperature.

The Aruba 8320 switch is not compatible with fan trays from other Aruba hardware platforms.

Installation precautions

To avoid personal injury or product damage when installing your switch, read the installation precautions and guidelines below.

• Do not mount the switch on a wall, on or under a table, or on or under any other horizontal surface.

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

• To prevent the rack or cabinet from becoming unstable and/or falling over, ensure that it is adequately secured.

• Ensure the power source circuits are properly grounded. Then connect the switch to the power source by using the power cord supplied with the switch.

• If your installation requires a different power cord than the one supplied with the switch and power supply, be sure the cord is adequately sized for the switch’s current requirements. In addition, be sure to use a power cord displaying the mark of the safety agency that defines the regulations for power cords in your country. The mark is your assurance that the power cord can be used safely with the switch and power supply.

• When installing the switch, the AC outlet should be near the switch and be easily accessible in case the switch must be powered off.

• Do not install the switch in an environment where the operating ambient temperature exceeds its specification. (See the Environmental Operating Temperature

• 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 the ampere ratings of all devices installed on the same circuit as the switch. Then 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.

• Ensure that the air flow around the switch is not restricted. Leave at least 3 inches (7.6 cm) for cooling.

information.)

If a power supply must be removed, and then reinstalled, wait at least 5 seconds before reinstallation. Otherwise, damage to the switch may occur.

The power supply needs this time to bleed off any retained power.

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 will be reported.

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

Figure 10: Installing a transceiver

Removing transceivers:

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

• A plastic tab on the bottom of the transceiver

• A plastic collar around the transceiver

•A wire bail

22 Aruba 8320 Switch Installation and Getting Started Guide

To remove the transceivers that have the plastic tab or plastic collar, push the tab or collar toward the switch until the transceiver releases from the switch (it will move outward slightly), then pull it from the slot.

To remove the transceivers that have the wire bail, lower the bail until it is approximately horizontal, and then using the bail, pull the transceiver from the slot.

4. Connect the switch to a power source

1. If a power supply is not already installed in the switch, install at least one power supply. (See the Aruba Switch

Power Supply Quick Setup Guide and Safety/Regulatory Information document shipped with your power supply units.) The Aruba 8320 switch uses any of the following power supplies:

• Aruba X371 400W 100-240VAC Power Supply (JL480A)

2. Plug the included power cord into the power supply’s power connector and into a nearby AC power source.

Figure 11: Connecting a power cord to the switch

3. Check the LEDs. See Switch and port LEDs on the front of the switch

One power supply provides power to operate the switch. Installing a second power supply can provide power to the switch in case the initial power supply fails. If the power supplies are plugged into different AC power sources, redundant power can be supplied in case of loss of one of the AC power sources.

5. Connect a management console

The Aruba 8320 switch has a full-featured, easy to use console interface for performing switch management tasks, including the following:

• Enabling switch ports (ports are disabled by default).

• Monitoring switch and port status and observing network activity statistics.

• Modifying the switch’s configuration to optimize switch performance, enhancing network traffic control, and improving network security.

• Reading the event log and accessing diagnostic tools to help in troubleshooting.

• Downloading new software to the switch.

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

Chapter 2 Installing the switch 23

The console can be accessed through these methods:

• Out-of-band serial: Use a serial cable (not included) for connecting a workstation running suitable VT-100 terminal emulation software directly to the switch’s RJ-45 Console Port. A DB9-to-RJ-45 console cable can be ordered from HPE: JL448A, Aruba X2C2 RJ45 to DB9 Console Cable.

• Out-of-band network: Access the console using SSH from a PC or UNIX station on the network running suitable VT-100 terminal emulation software. For more information, see chapter 3, Getting started with switch configuration.

The switch can simultaneously support one console session through the Console Port and multiple network SSH sessions.

Terminal configuration

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

• A baud rate of 115200.

• 8 data bits, 1 stop bit, no parity, and flow control set to off.

• For the Windows Terminal program, also disable (uncheck) the “Use Function, Arrow, and C 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 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.

trl Keys for

Direct console access

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

1. Connect the PC or terminal to the switch’s Console Port using a console cable (JL448A; sold separately).

Figure 12: Connecting a console cable

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

3. Press [Enter] two or three times. When prompted to log in specify admin. When prompted for the password,

press [Enter]. (By default, no password is defined.)

You are placed into the manager command context, which is identified by the prompt: switch#. For example:

6. Connect the network cables

Connect the network cables, described under “Cabling Infrastructure” (1. Prepare the installation site), from the network devices or your patch panels to the RJ-45 out-of-band management port on the switch or to any transceivers you have installed in the switch.

Using the RJ-45 out-of-band management port

If you plan to manage the switch from a dedicated management network, connect an RJ-45 network cable from the management network to the Mgmt port. The Mgmt port supports 10, 100, and 1000 Mbps connections.

To connect: Push the RJ-45 plug into the RJ-45 port until the tab on the plug clicks into place. When power is on for the switch and for the connected device, the Link LED for the port should light to confirm a powered-on device (for example, an end node) is at the other end of the cable.

Chapter 2 Installing the switch 25

If the Link LED does not go on when the network cable is connected to the port, see Diagnosing with the LEDs chapter 5, “Troubleshooting”.

To disconnect: Press the small tab on the plug and pull the plug out of the port.

Figure 14: Connecting an RJ-45

Connecting cables to SFP/SFP+/QSFP+ transceivers

If you have any transceivers installed in the switch, the type of network connections you will need to use depends on the type of transceivers installed. See chapter 6, Cabling and technology information

For transceiver ports, and in general for all the switch ports, a network cable from an active network device is connected to the port. If the port LED does not come on half-bright when the network cable is connected to the port, see Diagnosing with the LEDs

26 Aruba 8320 Switch Installation and Getting Started Guide

Chapter 3

Getting started with switch configuration

This chapter is a guide for using the console CLI 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, see the Basic Operation Guide and the Management and Configuration Guide for your switch at www.hpe.com/support/manuals (Intelligent Management Center), contact your HPE/Aruba representative. For information on Aruba AirWave, go to

www.arubanetworks.com/products/networking/management/airwave

. For information on the HPE IMC

Recommended minimal configuration

In the factory default configuration, the switch is optimized for secure deployments. It has no IP (Internet Protocol) address and subnet mask, all network ports are administratively shut down, the OOBM port is shut down, remote management protocols are disabled, and there is a default admin user account with no password configured. To manage the switch via a networked connection attached to the out-of-band management port, you must first enable the port and configure the switch with an IP address and subnet mask compatible with your network You must also configure a Manager password before enabling remote access methods such as SSH and the Web browser interface.

All switch port interfaces are disabled by default, you first need to enable all switch ports that you intend to use for network connections.

Many other features can be configured through the switch’s console interface to optimize the switch’s performance, to enhance your control of the network traffic, and to improve network security. Once an IP address has been configured on the switch, these features can be accessed more conveniently through a remote SSH session, through the switch’s Web browser interface, and from an SNMP network management station running network management software. For a listing of switch features available with and without an IP address, refer to “How IP Addressing Affects Switch Operation” in the Management and Configuration Guide.

For more information on configuring IP addressing, refer to the Basic Operation Guide at www.hpe.com/support/ manuals.

By default, the switch is configured to acquire an IP address configuration 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 Management and Configuration Guide.

Using the console CLI

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 and start a console session.

1. Using the method described in Terminal configuration the switch console command line interface (CLI) prompt (the default display).

The CLI prompt appears, for example:

, connect a terminal device to the switch and display

switch#

2. Enter the command config to change to the global configuration context: switch (config)#. For example:

switch# config switch(config)#

Chapter 3 Getting started with switch configuration 27

3. Define a password for the default admin account with the command user admin password. The local account password can contain up to 32 alphanumeric characters within the printable ASCII character-set. Spaces are not allowed. ASCII characters from hex 21 to hex 7E [\x21-\x7E] are allowed.

For example:

switch(config)# user admin password Changing password for user admin Enter password:************ Confirm password:************

4. Save the switch configuration changes by using the copy command.

switch# copy running-config startup-config

Enabling out-of-band management on the management port

The management port is disabled by default. Once enabled, it uses SSH to authenticate user logins and provided a secure connection for remote management. You must assign a password to the default admin account to enable SSH.

1. Enable the out-of-band management port using the following commands:

switch# configure switch(config)# interface mgmt switch(config-if-mgmt)# no shutdown

2. Enable the SSH server on the management VRF (mgmt) with the command ssh server vrf mgmt. By default, the SSH server will authenticate logins using the locally defined user accounts.

For example:

switch(config)# ssh server vrf mgmt

3. By default, management interface is set to operate as a DHCP client. If you prefer to use static addressing, define an IP address, default gateway, and DNS server with the commands ip, default-gateway, and nameserver.

For example, these commands set the management IP to 192.168.1.10 with a mask of 24 bits, the default gateway to 192.168.1.100, and the DNS server to 192.168.1.99:

switch(config)# interface mgmt switch(config-if-mgmt)# ip static 192.168.1.10/24 switch(config-if-mgmt)# default-gateway 192.168.1.100 switch(config-if-mgmt)# nameserver 192.168.1.99

You can specify IPv6 addresses instead of IPV4 addresses if required by your network.

4. Log out of the switch with the commands end and exit.

5. Use an Ethernet cable to connect the management port to your network.

6. Use an Ethernet cable to connect your computer to the same network.

7. Start your SSH client software and configure a new session using the address assigned to the management

port in step 2. You should now be able to establish a connection to the management port using SSH client software. When prompted, login with the admin account.

8. The switch can also be managed through a web browser interface using the address assigned to the management port in step 2. Use the command https-server to enable the web server and set the access mode, and then establish a connection to the management port using a web browser.

switch(config)# https-server vrf mgmt switch(config)# https-server rest access-mode read-write

When prompted, login with the admin account.

Chapter 4

Replacing components

This chapter shows you how to remove and install the following components:

• Power supply

• Fan tray

The power supplies and fan trays are hot swappable. You do not need to power off the switch before installing or replacing a power supply or fan tray.

The Aruba 8320 switch and its components are sensitive to static discharge. Use an antistatic wrist strap and observe all static precautions when replacing components.

If a power supply must be removed and then reinstalled, wait at least 5 seconds before reinstallation. Otherwise, damage to the switch may occur. The power supply needs this time to bleed off any retained power.

Replacing a power supply

If the Aruba 8320 switch is configured with a redundant power supply, the switch will not suffer any loss of traffic or performance if a power supply fails. To maintain system redundancy, a failed power supply should be replaced as soon as possible. The PS1 or PS2 LED will be on amber and flash simultaneously with the switch Global Status LED indicating a power supply has failed.

One power supply is available for use with the switch: Aruba X371 400W 100-240VAC Power Supply (JL480A)

To remove a power supply:

1. Remove the AC power cable from the failed power supply’s connector.

2. Grasping the handle of the failed power supply, release the locking mechanism by squeezing the latch handle

while removing the failed power supply.

Figure 17: Replacing a failed power supply

Chapter 4 Replacing components 30

3. Insert the new power supply. Slide it in all the way in until the locking mechanism clicks into place.

4. Connect the AC power cable to the new power supply’s connector.

Replacing a fan tray

The Aruba 8320 switch is equipped with five field-replaceable, hot-swappable fan trays. The switch can tolerate the failure of a single fan tray while maintaining a safe operating temperature. To maintain system redundancy, a failed fan tray should be replaced as soon as possible. The Fan LED will be on amber and blink simultaneously with the switch Global Status LED indicating a fan tray has failed.

One fan tray is available for use with the switch: Aruba X721 Front-to-Back Fan (JL481A)

The Aruba 8320 switch is not compatible with fan trays from other Aruba hardware platforms.

To replace a fan tray:

1. Identify the failed fan tray by its status LED. The fan tray LED will be on amber.

2. Remove the new fan tray from its packaging, being careful to not touch any of the circuitry on the board.

3. Loosen the retaining screw on the fan tray.

4. Grasping the handle of the failed fan tray, pull it straight out to remove it from its slot.

5. Insert the new fan tray fully into the slot so that its face plate is flush with the back face of the switch. If the

switch is connected to an AC power source, the fan tray should immediately start running.

6. Engage the retaining screw and tighten it. Be sure to not over-tighten the screw.

Troubleshooting

This chapter describes how to troubleshoot your switch. 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 full-featured console interface, the built-in web browser interface, and IMC, the SNMP-based network management tool, or Aruba AirWave. For more information, see the chapter “Troubleshooting” in the Management and Configuration Guide, which is on the Hewlett Packard Enterprise website at www.hpe.com/support/manuals

This chapter describes the following:

• Basic troubleshooting tips (see Basic troubleshooting tips

• Diagnosing with the LEDs (see Diagnosing with the LEDs

• Hardware diagnostic tests (see Hardware diagnostic tests

• Restoring the factory default configuration (see Restoring the factory default configuration

• Downloading new software to the switch (see Downloading new switch software

• Hewlett Packard Enterprise Customer Support Services (see Hewlett Packard Enterprise Customer Support Services)

)

Basic troubleshooting tips

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

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

• Non-standard cables. Non-standard and miswired cables may cause network collisions and other network problems, and can seriously impair network performance. Use a new correctly-wired cable or compare your cable to the cable in chapter 7, Cabling and technology information category 5 cable tester is a recommended tool for every 100BASE-TX and 1000BASE-T network installation.

• Improper network topologies. It is important to make sure 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.

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

for pinouts and correct cable wiring. A

For your switch, if you want to build redundant paths between important nodes in your network to provide some fault tolerance, you should enable Spanning Tree Protocol support on the switch. This 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 Traffic Management Guide for your switch at www.hpe.com/support/manuals

Chapter 5 Troubleshooting 32

Diagnosing with the LEDs

Table 14 shows LED patterns on the switch that indicate problem conditions for general switch operation

Diagnostic tips:

Tip Problem Solution

1 The switch is not

plugged into an active AC power source, or the switch’s power supply may have failed.

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

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

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

Diagnostic Tip

If the power source and power cord are OK and this condition persists, the switch power supply may have failed. Call your Hewlett Packard Enterpriseauthorized network reseller, or use the electronic support services from Hewlett Packard Enterprise to get assistance.

2 A switch hardware

failure has occurred. All the LEDs will stay on indefinitely.

Chapter 5 Troubleshooting 33

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

Tip Problem Solution

3 The switch has

experienced a software failure during self test, or one of the switch cooling fans may have failed.

4 The network port for

which the LED is flashing has experienced a self test or initialization failure.

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

If the fault indication reoccurs, attach a console to the switch (as indicated in chapter 2) and configure it to operate at 115200 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 typing “Show events” 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, the failed fan tray should be replaced.

If necessary to resolve the problem, contact your Hewlett Packard Enterpriseauthorized network reseller, or use the electronic support services from Hewlett Packard Enterprise to get assistance.

If the port is an SFP/SFP+/QSFP+ transceiver, verify that it is one of the transceivers supported by the switch. Unsupported transceivers will be identified with this fault condition. The supported transceivers are listed in Chapter 1, Introducing the Aruba 8320 Switch tested when they are “hot-swapped”—installed or changed while the switch is powered on.

To verify the port has failed, remove and reinstall the transceiver without powering off the switch. If the port fault indication reoccurs, check the event log to see why the transceiver failed. You may have to replace the transceiver. Try power cycling the switch. Call your Hewlett Packard Enterprise-authorized network reseller, or use the electronic support services from Hewlett Packard Enterprise to get assistance.

. The transceivers are also

34 Aruba 8320 Switch Installation and Getting Started Guide

Tip Problem Solution

5 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.

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

For fiber-optic connections, verify 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.

The cable verification process must include all patch cables from any end devices, including the switch, to any patch panels in the cabling path.

Verify the port has not been disabled through a switch configuration change. You can use the console interface, or, if you have configured an IP address on the switch, use the Web browser interface to determine the state of the port and re-enable the port if necessary.

Verify the switch port configuration matches the configuration of the attached device. For example, if the switch port is configured as “Full-duplex”, the port on the attached device also MUST be configured as “Full-duplex”. If the configurations don’t match, the results could be a very unreliable connection, or no link at all.

If the other procedures don’t resolve the problem, try using a different port or a different cable.

6 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. The show lacp interfaces command displays the port status for the LACP feature; the show spanning-tree command displays the port status for Spanning Tree.

Also check the Port Status screen using the show interfaces command to see if the port has been configured as “disabled”.

Other switch features that may affect the port operation include VLANs and IGMP. Use the switch console to see how the port is configured for these features.

For software troubleshooting tips, see the chapter “Troubleshooting” in the Management and Configuration Guide, which is on the Hewlett Packard Enterprise website at www.hpe.com/support/manuals

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.

Chapter 5 Troubleshooting 35

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

• 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 reset. These reset processes

also cause any network traffic 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 for information on interpreting the LED patterns.

Checking console messages

Useful diagnostic messages may be displayed on the console screen when the switch is reset. As described in chapter 2 under step 6, connect a PC running a VT-100 terminal emulator program to the switch’s Console Port and configure it to run at 115200 baud, and with the other terminal communication settings shown in Terminal configuration. Then, 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 events command.

Testing switch-to-device network communications

You can perform the following communication tests to verify 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 identified by its MAC address

• Ping Test—a network layer test used on IP networks that sends test packets to any device identified by its IP address

These tests can be performed through the switch console interface from a terminal connected to the switch or through a Telnet connection, or from the switch’s web browser interface. For more information, see the Basic Operation Guide, which is on the Hewlett Packard Enterprise website at www.hpe.com/support/manuals

Testing end-to-end network communications

Both the switch and the cabling can be tested by running an end-to-end communications test—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.

36 Aruba 8320 Switch Installation and Getting Started Guide

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, and reboots the switch into its factory default configuration including deleting the IP address, if one is configured.

This process removes all switch configuration changes that you have made from the factory default settings. This includes, for example, configuration of VLANs, Spanning Tree, and LAGs. Returning the configuration of these features to their factory default settings (usually disabling them) may result in network connectivity issues.

If the switch has a valid configuration, and you are restoring the factory default settings for a reason other than configuration problems, you should save the switch configuration prior to performing the factory default reset. Then, after the reset and resolution of the original problem, you can restore the saved configuration to the switch.

You can restore the factory default configuration either on the switch itself, or through the switch console.

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

1. Using a pointed object, press the Reset button on the front of the switch.

2. When the Global Status LED begins to fast flash orange (after approximately 5 seconds), release the Reset

button.

The switch will then begin operating with its configuration restored to the factory default settings.

To restore the factory default configuration using the console, execute the erase startup-config command from the console command prompt.

Downloading new switch software

Software Updates can be downloaded to the switch through several methods. See Accessing updates.

Cabling and technology information

This chapter includes switch connector information and network cable information for cables that should be used with the Hewlett Packard Enterprise switches.

Incorrectly wired cabling is a common cause of problems for LAN communications. Hewlett Packard Enterprise recommends that you work with a qualified LAN cable installer for assistance with your cabling requirements.

Cabling specifications

below, and

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 specifications, 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

Chapter 7 Cabling and technology information 41

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.

Note on 10GBASE-T cable requirements

The Category 6 networking cables that work for 1000BASE-T connections may work for 10GBASE-T, as long as the distance is less than 55m and the cable installation has been tested for compliance to IEEE requirements. But, for the most robust connections, you should use cabling that complies with the Category 6A or Category 7 specifications, as described in the TIA-568-C (ANSI/TIA-568-C.2) and ISO/IEC 11801 standards. 10GBASE-T is a sophisticated technology that relies upon high quality cable installations. It is sensitive to Alien Near End

Crosstalk (ANEXT) which can arrive upon the cable due to cables placed in close proximity to the data cables. It is recommended that cable dressing be done carefully and in compliance with recommendations in the TIA TSB155A.

Like 1000BASE-T, 10GBASE-T requires testing of all the crosstalk and return loss parameters described above, and also ANEXT.

In addition to ANEXT, 10GBASE-T is more sensitive to external electrical noise in the environment. It is recommended that radio transmitters and other sources of high frequency continuous wave radio frequency be kept away from LAN cables.

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. For 10GBASE-T, Category 6 patch cables are sensitive to movement once link has been established, and could cause link to drop if moved. Therefore, Hewlett Packard Enterprise recommends using Category 6A patch cables, or using cable management options to tie down (dress) the Category 6 patch cables so they cannot move.

For Conducted and Radiated Immunity in accordance with EN55024, the Aruba switch is limited to Performance Criteria A with shielded cables (CAT6/6A).

Mode conditioning patch cord

The following information applies to installations in which multimode fiber-optic cables are connected to a GigabitLX port. Multimode cable has a design characteristic called “Differential 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 Gigabit-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 fiber-optic port in your switch and your multimode fiber-optic network cabling, at both ends of the network link.

The patch cord consists of a short length of single mode fiber cable coupled to graded-index multimode fiber cable on the transmit side, and only multimode cable on the receive side. The section of single mode fiber is connected in such a way that it minimizes the effects of the differential mode delay in the multimode cable.

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

Installing the patch cord

As shown in the illustration below, connect the patch cord to the transceiver with the section of single mode fiber 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 fiber.

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.

Make sure you purchase a patch cord that has appropriate connectors on each end, and has multimode fibers that match the characteristics of the multimode fiber 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).
