1 Introducing the 3810M switches
The Aruba 3810M are multiport switches that can be used to build high-performance switched
networks. These switches are store-and-forward devices offering low latency for high-speed
networking. The 3810M switches also support a field-replaceable Redundant Power Supply and
fan tray, Power over Ethernet (PoE/PoE+) technologies, full network management capabilities
and a flexible uplink port slot.
In addition, the 3810M switches support the FlexChassis Mesh feature for stacking the switches.
When 3810M Stacking Modules (JL084A) are installed in the switches, any combination of up
to ten 3810M switches can be stacked together via high-speed backplane cables to form a single
extended virtual switch. See Stacking Information and Topologies, and the HPE ArubaOS-Switch
Advanced Traffic Management Guide K/KA/KB.16.01 for more stacking information.
These switches are described in this manual:

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 either by using the RJ-45 serial cable supplied with the
switch, or a standard Micro USB cable (not supplied). The Micro USB connector has precedence
for input, so if both cables are plugged in, the console output is echoed to both the RJ and
Micro-USB ports. But, the input is only accepted from the Micro-USB.
For more information on the console connection, see “10. (Optional) Connect a Management
console” (page 44). The console can be a PC or workstation running a VT-100 terminal emulator,
or a VT-100 terminal.
Auxiliary (Aux) Port
An auxiliary port for processing a USB command file or downloading switch software code. This
port uses a USB Type A connector, but does not comply with all USB protocols and standards.

Looking at any member, you can see that there are 4 members defined in the stack configuration,
with member numbers 1, 2, 3, and 5 because these are the LEDs that are lit. The port 4 LED is
off, indicating that this member number is not defined in the stack.
On all members, Port 1 LED is fast flashing, indicating that member 1 is the commander of the
stack. Port 3 LED is on orange, indicating either that 3 is rebooting or not communicating because
of an unknown fault.
When looking at member 1, only Port 1 LED is fast flashing green. This indicates that this unit
is member 1 and is the commander.
When looking at member 2, the port 2 LED is slow flashing green, indicating that unit is member
number 2. Likewise on member 5, the port 5 LED is slow flashing green, indicating that unit is
member 5.
Member 3 will be going through the normal boot LED boot up sequence. When it has completed
booting and joined the stack, if you exit and re-enter USER mode, the members show the following

Stacking Notes:
• For 3810M switches that are in a stack, the Mode select button on every switch in the stack
controls the LED mode for all the switches in the stack. Using the Mode select button on
one switch in the stack changes the LED mode for the entire stack.
• If there is a combination of PoE/PoE+ switches and non-PoE switches in the stack, when
any of the Mode select buttons is pressed to put the stack into PoE mode, the non-PoE
switches indicate no PoE support by not illuminating any of the Mode indicator LEDs or any
of the port LEDs.
• If any of the switches in the stack are configured with the Save Power LED feature, then
the default LED Mode for the whole stack becomes the Save Power display (all LED Mode
indicator LEDs are off), but only the stack members on which that feature is configured
display the other characteristics of that feature (all LEDs Off except for the Power LED).
Reset and Clear Buttons
The Reset and Clear buttons are recessed from the front panel (to protect them from being
pushed accidentally) and 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:

Flex Port Slot and Module Support
The 3810M family of switches features a module slot(s) that allows the user to customize the
uplink ports on the switch. Depending on the switch model, the slot supports either 40Gbps or
80Gbps of maximum bandwidth and therefore, not all modules are supported in all slots. See
Switch Module/Support Matrix, for the switch module/support matrix.
NOTE: The unsupported modules are mechanically prevented from installing into unsupported
slots.

Power Supplies
There are three power supplies that can be installed into the 3810M switches:
• Aruba X371 12VDC 250W 100-240VAC Power Supply (JL085A)—A 250 watt power supply
for the non-PoE switches. This power supply does not provide any PoE power, and is keyed
so that it will not fit into the power supply slots of 3810M PoE+ switches.
• Aruba X372 54VDC 680W 100-240VAC Power Supply (JL086A)—A 680 watt power supply
for 3810M PoE+ supported switches. This power supply offers up to 370 watts of PoE+
power, and is keyed so that it does not fit into the power supply slots of non-PoE+ 3810M
switches.
• Aruba X372 54VDC 1050W 110-240VAC Power Supply (JL087A)—A 1050 watt power
supply for 3810M PoE+ supported switches. This power supply offers up to 740 watts of
PoE+ power, and is keyed so that it does not fit into the power supply slots of non-PoE+
3810M switches.
For more power supply information see 9. (Optional) Installing a Second Power Supply.
Power Connector
The 3810M switches do not have a power switch. They will power on when either one or both
power supplies are connected to an active AC power source.
Redundant Power Supply slot 25
Stacking Module Slot
Each of the 3810M switches has one module slot that can accept the 3810M Stacking Module

Switch Features
The features of the 3810M switches include:
• Combinations of fixed 10/100/1000-T, HPE SMART RATE and SFP/SFP+ ports, as described
under Network Ports.
• Selected switch models feature HPE SMART RATE ports and provide 1Gbps, 2.5Gbps,
5Gbps and 10Gbs connectivity. See the appendices for cabling recommendations and
requirements.
• All switch models feature either 1 or 2 Flex Port Module slots, that allow configuration with
either 10G SFP+ or 40G QSFP+ ports, as described in Flex Port Slot and Module Support.
• One module slot is provided in the back of the switches to support a stacking module to
provide connectivity to other 3810M switches with stacking modules. See Stacking
Information and Topologies, the HPE ArubaOS-Switch Advanced Traffic Management Guide
K/KA/KB.16.01 for more information about stacking.
• Power over Ethernet (PoE+) operation—Aruba 3810M 24G PoE+ 1-slot Switch (JL073A),
Aruba 3810M 48G PoE+ 1-slot Switch (JL074A) and Aruba 3810M 40G 8 HPE Smart Rate

to 30W per port to power IP phones, wireless access points, indoor web cameras, and more.
For more information, see the HPE Power over Ethernet (PoE/PoE+) Planning and
Implementation Guide, available from http://www.hpe.com/networking/support.
The switches support 802.3af and 802.3at standard devices and some pre-standard PoE
devices. For a list of these devices, see the FAQs (Frequently Asked Questions) for your
switch model. PoE is enabled by default. (For instructions, see the 3810M Management and
Configuration Guide for your switch at http://www.hpe.com/networking/support.
• The option to have one or two internal power supplies.
A second power supply supports redundant system power and/or redundant/additional PoE
power. If one of the internal power supplies fails, the second power supply immediately
provides the power necessary to keep the switch running, including PoE+ power on an
allocated basis.
If maximum PoE+ power is used on the 48 port PoE+ switch, the second power supply is
needed for PoE+ power but there is no PoE power redundancy. However, system power is
always maintained. On a power supply failure, the system drops the PoE power on ports
based on user priority, to maintain system power. For more information on Power Supplies,
see Power Supplies.
• Plug-and-play networking—all ports are enabled by default—just connect the network cables
to active network devices and your switched network is operational.
• Auto MDI/MDI-X on all twisted-pair ports (10/100/1000 and 10GBase-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 configures the port as MDI; if the switch detects that an end-node device is
connected to the port, it configures the port as MDI-X. (See the appendices for recommended
or required cabling.)
• Automatic learning of the network addresses in each switch’s 64000-address forwarding
table, (with configurable 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.
◦ IMC—An SNMP-based, graphical network management tool that you can use to manage
your entire network.
• Support for the Spanning Tree Protocol to eliminate network loops.
• Support for up to 4096 IEEE 802.1Q-compliant VLANs so you can divide the attached end
nodes into logical groupings that fit your business needs.
• Support for many advanced features to enhance network performance—for a description,
see the 3810M Management and Configuration Guide at http://www.hpe.com/networking/
support.
• Ability to update the switch software. Software updates are routinely available from Hewlett
Packard Enterprise.
26 Introducing the 3810M switches
Page 27
• An auxiliary port (USB Type A connector) for processing a USB command file and updating
switch software.
• Low power operation:
◦ Ports on a switch or stack member may be set to operate at reduced power.
◦ Port status LEDs may be turned off.
◦ RJ-45 ports will operate at reduced power if the port is not connected (link partner is
not detected).
Switch Features 27

Summary
1. Prepare the installation site (“ 1. Prepare the Installation Site” (page 31)). Ensure the
physical environment is properly prepared, including having the correct network cabling
ready to connect to the switch and having an appropriate location for the switch. See “
Installation Precautions:” (page 31) for some installation precautions.
NOTE: For steps 2 and 3 below, if an 3810M switch is powered on for the first time without
a stacking module installed, stacking will be disabled and that will be saved in the switch's
running configuration. For more information, see Stacking Information and Topologies.
Installation Procedures 29
Page 30
2. Verify the switch passes self test ( “ 2. Verify the Switch Boots Correctly” (page 32) ).
Plug the switch into a power source and observe that the LEDs on the switch’s front panel
indicate correct switch operation. When self test is complete, unplug the switch.
3. (Optional) Install the stacking module ( 3. (Optional) Install the Stacking Module).
4. (Optional) Install the Flex Port module (4. Installing the Flex Port Module).
5. Mount the switch ( “5. Mount the Switch” (page 37) ). The Switch can be mounted in the
19-inch telco rack, in an equipment cabinet, or on a horizontal surface.
6. (Optional) Install the stacking cables ( 6. (Optional) Installing the Stacking Cables). If
you have installed the module, you can now install up to four stacking cables and connect
them to other switches in the desired stacking topology.
7. (Optional) Install or remove SFP transceivers (mini-GBICs) (7. (Optional) Installing
Transceivers). Depending on the switch model purchased and optional Flex Port module
configuration, the switch can support SFP/SFP+ or QSFP+ transceivers. Depending on
where the switch is mounted, it may be easier to install the transceivers first. All transceiver
types can be installed or removed while the switch is powered on.
8. Connect the switch to a power source ( 8. Connect the Switch to a Power Source).
Once the switch is mounted, plug it into the nearby main power source.
9. (Optional) Install a second power supply ( 9. (Optional) Installing a Second Power
Supply). You may wish to use a second power supply with the switch to provide redundant
power or added PoE+ power.
10. (Optional) Connect a Management console (10. (Optional) Connect a Management
console). You may wish to modify the switch’s configuration, for example, to configure an
IP address so it can be managed using a web browser, from an SNMP network management
station, or through a Telnet session. Configuration changes can be made easily by using
the included console cable to connect a PC to the switch’s console port.
11. Connect the network cables (“ 11. Connect the Network Cables” (page 46)). Using the
appropriate network cables, connect the network devices to the switch ports.
At this point, the switch is fully installed. See the rest of this chapter if you need more detailed
information on any of these installation steps.

Installation Precautions:
Follow these precautions when installing the 3810M switches.
WARNING!
• The rack or cabinet should be adequately secured to prevent it from becoming unstable
and/or falling over.
• Devices installed in a rack or cabinet should be mounted as low as possible, with the
heaviest devices at the bottom and progressively lighter devices installed above.
CAUTION:
• If the switch is to be shipped in a rack, it can be mounted and shipped in a Hewlett Packard
Enterprise 10K rack using the HPE X410 Universal Rack Mounting Kit (J9583A). Additionally,
it can be mounted in many 4-post racks using the HPE X410 Universal Rack Mounting Kit
(J9583A).
• Ensure the power source circuits are properly grounded, then use the power cord supplied
with the switch to connect it to the power source.
• 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 should be easily
accessible in case the switch must be powered off.
• Ensure 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.
• For safe operation, proper switch cooling, and reduction of electromagnetic emissions,
ensure that a slot cover is installed on any unused module or power supply slot.
• Do not install the switch in an environment where the operating ambient temperature might
exceed 45°C (113°F).
• Ensure the air flow around the sides and back of the switch is not restricted.
1. Prepare the Installation Site
Cabling Infrastructure - Ensure the cabling infrastructure meets the necessary network
specifications. See Cabling and Technology Information in the appendices 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 7.6 cm (3 inches) of space for the twisted-pair and
fiber-optic cabling.
• In the back of the switch, leave at least 3.8 cm (1 1/2 inches) of space for the power cord.
If you are stacking the switches, you will need 20 to 23 cm (approximately 8 to 9 inches),
depending on the lengths of the stacking cables being used.
• On the sides of the switch, leave at least 7.6 cm (3 inches) for cooling, except if the switch
is installed in an open EIA/TIA rack.

2. Verify the Switch Boots Correctly
NOTE: For steps 2 and 3, if an 3810M switch is powered on for the first time without a stacking
module installed, stacking will be disabled and that will be saved in the switch's running
configuration. For more information, see Stacking Information and Topologies.
Before installing the switch in its network location, you should first verify it is working properly by
plugging it into a power source and verifying that it boots correctly.
32 Installing the Switch
Page 33
1. Connect the power cord supplied with the switch to the power connector on the back of the
switch, and then into a properly grounded electrical outlet.
Figure 10 Connecting the Power cord
NOTE: The 3810M 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, the power outlet
should be located near the switch installation.
The switch automatically adjusts to any voltage between 100-240 (110–240 for JL087A
power supply) and either 50 or 60 Hz. No voltage range settings are required.
If your installation requires a different power cord than the one supplied with the switch, be
sure to use a power cord displaying the mark of the safety agency that defines the regulations
for power cords in your country. The mark is your assurance that the power cord can be
used safely with the switch.
2. Check the LEDs on the switch as described below.

Switch Port LEDs1
Mode LEDs2
When the switch is powered on, it performs its diagnostic self test and initialization. This boot
process, depending on switch model and configuration, 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 on green and
bi-color LEDs will change to orange, then back to green.
• The Global Status LED will start blinking green, indicating the switch is going thru its self-test
and will continue to blink green until the switch if fully booted.
• The Port LEDs will come on green, turn orange, turn back to green, and then may blink on
and off during phases of the boot.
When the switch boots successfully, the LEDs display:
• Global Status and Back LEDs will be on solid green.
• Locator LED is off.
3
Back LED
Global Status and UID LEDs4
• Other status LEDs may be on or off depending on the switch configuration 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 flickering full-bright green
to show network traffic.
◦ If the ports are not connected to active network devices, the port LED will stay off.
If the LED display is different than what is described above, especially if the Global Status LED
continues to blink green for more than 120 seconds or blinks orange continually, then the switch
boot has not completed correctly. Refer to “ Troubleshooting” (page 68) for diagnostic help.
3. (Optional) Install the Stacking Module
NOTE: Hot swapping the Stacking Module is not supported. If a module is installed with the
switch powered on, self-test of the module will not occur, the Back LED on the front of the switch
and the Module Status LED on the module will blink orange. The switch must be reset or power
cycled for the module to function. Only insert or remove a module during scheduled downtime
with the switch powered off.
1. Remove the cover plate.
2. Insert the module aligning with the guides in the slot.
3. Once the contacts have engaged, use the extractor handles to seat the module completely.

5. Mount the Switch
After the switch passes self test, the switch is ready to be mounted in a stable location. The
3810M switches can be mounted in these ways:
• in a rack or cabinet
• on a horizontal surface
For other mounting options contact your local Hewlett Packard Enterprise authorized network
reseller or Hewlett Packard Enterprise representative.
Rack or Cabinet Mounting
These switches are designed to be mounted in any EIA-standard 2-post 19-inch telco rack or
4-post communication equipment cabinet.
WARNING! For safe operation, please read the mounting precautions on“ Installation
Precautions:” (page 31), before mounting a switch.
Equipment Cabinet Note:
The 12-24 screws supplied with the switch are the correct threading for standard EIA/TIA open
19-inch racks. If you are installing the switch in an equipment cabinet such as a server cabinet,
use the clips and screws that came with the cabinet in place of the 12-24 screws that are supplied
with the switch.
Complete step 1, and plan which four holes you will be using in the cabinet and install all four
clips. Then proceed to step 2.
Installation Procedures 37
Page 38
Rack Mounting the 3810M switch in a 2-post rack
1. Use a #1 Phillips (cross-head) screwdriver and attach the mounting brackets to the switch
with the included 8-mm M4 screws.
Figure 15 Attaching the mounting brackets to the switch
NOTE: The mounting brackets have multiple mounting holes and can be rotated allowing
for a wide variety of mounting options. These include mounting the switch so its front face
is flush with the face of the rack as shown in the illustration, or mounting it in a more balanced
position.
2. Hold the switch with attached brackets up to the rack and move it vertically until rack holes
line up with the bracket holes, then insert and tighten the four number 12-24 screws holding
the brackets to the rack.

4. Securing the switch in rack after installation.
Figure 20 Secure the switch
Horizontal Surface Mounting
Place the switch on a table or other horizontal surface. The switch comes with rubber feet in the
accessory kit that can be used to help keep the switch from sliding on the surface.
Attach the rubber feet to the four corners on the bottom of the switch within the embossed angled
lines. Use a sturdy surface in an uncluttered area. You may want to secure the networking cables
and switch power cord to the table leg or other part of the surface structure to help prevent tripping
over the cords.
CAUTION: Make sure the air flow is not restricted around the sides and back of the switch.
40 Installing the Switch
Page 41
6. (Optional) Installing the Stacking Cables
NOTE: Hot swapping stacking cables is supported. You can install or remove a stacking cable
with the switch powered on.
a. Slide in the stacking cable connector until it clicks into place. Pull on the cable connector (not
the tab) to make sure that it is fully latched.
Figure 21 Installing a stacking cable
b. Connect the other end of the cable to a Stacking Module in another 3810M switch. See
Stacking Information and Topologies for connectivity.
NOTE: When switch power is on and one end of the stacking cable is inserted, the Link and
Module Status LEDs on the module, and the Back LED on the front of the switch blinks orange
until the other end is connected to another switch stacking module. The LEDs turn solid green
when the cable is fully seated at both ends and a link is established.
To remove the stacking cable pull the tab on the stacking cable connector straight out.
7. (Optional) Installing Transceivers
You can install or remove transceivers from the slots on the front of the switch without having to
power off the switch.
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.
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
Installation Procedures 41
Page 42
seconds, with the worst case being 5 seconds. If the transceiver is removed before the
authentication completes a self test failure will be reported.
WARNING! The Hewlett Packard Enterprise transceivers are Class 1 laser devices. Avoid
direct eye exposure to the beam coming from the transmit port.
Figure 22 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 different release
mechanisms: a plastic tab on the bottom of the transceiver, a plastic collar around the transceiver,
or a wire bail.
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.
8. Connect the Switch to a Power Source
1. Plug the included power cord into the switch’s power connector and into a nearby AC power
source.
2. Re-check the LEDs during self test. See “LED Behavior” on LED Behavior:.
42 Installing the Switch
Page 43
Stacking Note:
If you are stacking your 3810M switches, then the first switch you should power on is the switch
that you want to be the stack Commander. The second switch that you power on should be the
one that you want to be the stack Standby. For the other switches in the stack, their member ID
will be determined by the order in which they are booted. For more information, see Stacking
Information and Topologies.
9. (Optional) Installing a Second Power Supply
There are three types of power supplies that can be installed:
• Aruba 250W Power Supply, (JL085A, Aruba X371 250W 100-240VAC to 12VDC PS) is
used with the non-PoE switches and is keyed so that it cannot be used in the PoE/PoE+
switches.
The 250W 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, then redundant power can be supplied
in case of loss of one of the AC power sources.
• Aruba 680W PoE+ Power Supply, (JL086A, Aruba X372 680W 100-240VAC to 54VDC
PS) used with the PoE/PoE+ switches and is keyed so that it cannot be used in the non-PoE
switches.
• Aruba 1050W PoE+ Power Supply, (JL087A, Aruba X372 1050W 100-240VAC to 54VDC
PS) is used with the PoE/PoE+ switches and is keyed so that it cannot be used in the non-PoE
switches.
The 680W and 1050W power supplies provide two types of power to the PoE/PoE+ switches:
• The 680W and 1050W power supplies provide 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, then redundant power
can be supplied in case of loss of one of the AC power sources.
• Power-over-Ethernet (PoE/PoE+) power. The power supplies, supply PoE/PoE+ power to
the switch. Should one of the power supplies fail, the second power supply will supply the
needed PoE/PoE+ power to continue PoE operation. For the 48 port switches, the second
power supply’s PoE/PoE+ power is additional power made available to the switch’s ports.
For further information regarding the power supply’s PoE/PoE+ capabilities, see the HPE
Power over Ethernet (PoE/PoE+) Planning and Implementation Guide, on the Hewlett
Packard Enterprise website at http://www.hpe.com/networking/support.
PoE/PoE+ Operation
It is important to understand the PoE/PoE+ power requirements of the switches because if the
PoE/PoE+ power is not planned and implemented correctly the end devices connected to the
switch ports may not receive power if an internal switch PoE/PoE+ power supply should fail.
For further information regarding the PoE/PoE+ capabilities, see the HPE Power over Ethernet
(PoE/PoE+) Planning and Implementation Guide, on the Hewlett Packard Enterprise website at
http://www.hpe.com/networking/support.
Installation Procedures 43
Page 44
10. (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’s configuration to optimize switch performance, enhance network traffic
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.
After you install and power up the Switch, you must use the console port connection to minimally
configure the switch with an IP address and subnet mask before you can use a networked (in-band
or out-of-band) connection to manage the switch. The minimal switch configuration is described
in “Minimal Configuration Through the Out-of-Band Console Connection” on Minimal Configuration
Through the Console Port Connection.
To connect a console to the switch, use the console cable shipped with the switch and connect
a PC or VT-100 terminal to the Console serial port. The PC or terminal then functions as a
management console connected directly to the switch.
You can use the Console port only for out-of-band management; it cannot be used for a Telnet
connection.
Configuring the Management Console
To set up a console to manage the switch through the Console port connection:
1. Configure the PC terminal emulator as a DEC VT-100 (ANSI) terminal or use a VT-100
terminal.
2. Configure the terminal with the following settings:
• A baud rate from 1200 to 115200 (the switch senses the speed)
• 8 data bits, 1 stop bit, no parity, and flow control set to Xon/Xoff
• For the Windows Terminal program, disable (uncheck) the “Use Function, Arrow, and
Ctrl Keys for Windows” option.
If you use a management console with different configuration settings, be sure to reconfigure
the settings on both the terminal and the switch in the following order so that both configurations
are compatible:
1. Reconfigure the switch and save the new settings.
2. Reconfigure the terminal and save the new settings.
3. Reboot the switch and re-establish the console session.
Setting Up a Console Connection
To access the Switch through a Console port (out-of-band) connection, connect an RJ-45 or
micro-USB console cable.
44 Installing the Switch
Page 45
IMPORTANT: You must use the out-of-band console connection to minimally configure the
switch with an IP address and subnet mask before you can use an in-band or out-of-band
networked connection to manage the switch. Continue with Minimal Configuration Through the
Console Port Connection for more information.
Console Cable Pinouts
The console cable has an RJ-45 plug on one end and a DB-9 female connector on the other
end. Mapping of RJ-45 to DB-9 describes the mapping of the RJ-45 to DB-9 pins.

To connect:
Push the RJ-45 plug into the
RJ-45 jack until the tab on the plug
clicks into place. When power is
on for the switch and for the
connected device, the port LED
should come on half-bright to
indicate link is established. If the
port LED does not come on when
the network cable is connected,
see “ Diagnosing with the LEDs”
(page 69), in chapter 5,
“Troubleshooting”. To disconnect:
Press the small tab on the plug
and pull the plug out of the jack
Connecting Cables to 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.
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” (page 69) in chapter 5,
“Troubleshooting”.
(Optional) Insert transceivers.
Stacking Information and Topologies
The 3810M switches support the FlexChassis Mesh feature for stacking the switches. When
3810M Stacking Modules (JL084A) are installed in the switches, any combination of up to ten
3810M switches can be stacked together via high-speed backplane cables to form a single
Stacking Information and Topologies 47
Page 48
extended virtual switch. The stacking topologies supported depend on the number of switches
being stacked.
The stacking cables and connections operate independently of any layer 2 or layer 3 network
protocols and features, including Spanning Tree. When multiple switches are stacked, they
behave as a single, virtual switch with additional network ports being supplied by the stack
members.
NOTE: If an 3810M switch is powered on for the first time without a stacking module installed,
stacking will be disabled and that will be saved in the switch's running configuration. Subsequently,
after a stacking module has been installed, stacking must be enabled through the console (CLI)
command stacking enable.
To set up a stack of 3810M switches, you should:
1. Power off all switches that are going to be stacked.
2. Install Stacking Modules in the switches, and connect the stacking cables to create your
stacking topology.
3. Power-on each switch, one at a time. The first switch that you should power on is the one
that you want to be the Commander of the stack. The second one will become the stack
Standby. For the other stack members, their Member ID is determined by the sequence in
which they are booted.
There are additional methods for creating your 3810M stack. For configuration options and other
information on stacking, see “Stack Management” chapter in the HPE ArubaOS-Switch Advanced
Traffic Management Guide K/KA/KB.16.01.
The supported stacking topologies include the following:
• Chain
• Ring
• Mesh
Chain Topologies
Up to 10 switches may be stacked in an open-ended chain with single cables between each pair
of switches.
NOTE: Chain topologies are not recommended because a single failure (switch, stacking
module, or cable) will cause switch-to-switch communication failures between switches that are
located on opposite sides of the failure. Unless the failure is the switch or stacking module at the
very end of the chain, two stack fragments are formed as a result. One of the fragments becomes
inactive to make sure that network topology and protocol rules are not violated by the creation
of two virtual switches. For the inactive fragment, the switches remain powered on and create a
separate stack, but all of network ports on the switches in the inactive fragment become disabled
and do not pass network traffic.
For more information and recovery procedures, see the “Stack Management” chapter in the HPE
ArubaOS-Switch Advanced Traffic Management Guide K/KA/KB.16.01.
A typical chain topology is illustrated in Figure 25.

Table 20 Cable Connection for Chain Topologies Label and Description
Ring Topologies
Up to 10 switches may also be connected in closed ring topologies. Ring topologies afford some
protection from a single failure because communication between the switches continues, in a
direction away from the failure.
A typical ring topology is illustrated in Figure 27 (page 50).

Mesh Topologies
Two to five switches may be stacked using mesh topologies.
In mesh topologies, every switch in the stack is connected to every other switch in the stack.
Hence, with four stacking ports on the Stacking Module, the maximum number of switches that
can be meshed together is limited to five.
Mesh topologies provide the most protection from stacking failures because communications
can be rerouted through multiple paths.
Typical mesh topologies are illustrated in Figure 29 (page 52).

more topology information, visit the product’s website at http://www.hpe.com/networking/support.
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 31 Example as a Desktop Switch Implementing PoE/PoE+
This illustration is an example of the switch being configured to supply PoE/PoE+ power to end
devices such as IP telephones and wireless access points (WAPs).
As shown in Example as a Desktop Switch Implementing PoE/PoE+, 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.
54 Installing the Switch
Page 55
Figure 32 Example as a Segment Switch
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 hubs that form those
segments to the switch, or you can also connect other switches.
In the illustration above, two “Fast” Ethernet hubs with PCs, printers, and local servers attached,
are both connected to a Switch. The devices attached to the two hubs can now communicate
with each other through the switch. They can also all communicate with the server that is
connected to a 1000Base-T port on the switch.
Because the Switch has the “IEEE Auto MDI/MDI-X” features, the connections between the
switch and the hubs, and between the switch and end nodes or servers can be through category
5 straight-through or crossover twisted-pair cable.
Category 3 or 4 cable can also be used if the connection is 10 Mbps only. In all cases, the device
ports must be configured to auto negotiate the link characteristics for this feature to work.
The switch, in turn, can be connected to a network backbone through fiber-optic cabling connected
to a Gigabit-SX, -LX, or -LH 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.
Sample Network Topologies 55

Figure 33 Example as a Segment Switch Implementing PoE/PoE+
As shown in Example as a Segment Switch Implementing PoE/PoE+, the IP telephones have
been inserted in between the 3810M-PoE+ switch and the PCs, and a WAP has been connected
to the 3810M-PoE+ switch. Only devices directly connected to the PoE+ switches can receive
PoE/PoE+ power. Devices connected to a non-PoE+ switch cannot receive PoE/PoE+ power.
56 Installing the Switch
Page 57
Figure 34 Example of connecting to a Backbone Switch
For example, you can use an Aruba 5406R zl Switch to interconnect each of your smaller switched
workgroups to form a larger switched network. All the devices in this network can communicate
with each other. For example, with 8port 1G/10GbE SFP+ v3 zl2 Modules and associated
SFP/SFP+ transceivers in the Aruba 5406R zl switch, the entire switched topology can be
connected to a campus backbone as shown in Example of connecting to a Backbone Switch.
NOTE: In the Backbone Switch illustration, the fiber-optic connection between the 3810M
Switch and the 5406R zl Switch is by way of an Aruba 3810M 4SFP+ Module installed in the
3810M Switch, and connected to an 8port 1G/10GbE SFP+ v3 zl2 Module in the 5406R zl Switch.
The appropriate SFP+ transceivers are installed into each module.

3 Getting Started With Switch Configuration
This chapter is intended as a guide for using the console Switch Setup screen to quickly assign
an IP (Internet Protocol) address and subnet mask to the switch, set a Manager password, and,
optionally, configure other basic features.
For more information on using the switch console and the other switch management interfaces:
the web browser interface and the SNMP management tool, Aruba IMC, see the Management
and Configuration Guide, which is on the Hewlett Packard Enterprise website at http://
www.hpe.com/networking/support.
Recommended Minimal Configuration
In the factory default configuration, 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 a networked (in-band data port or out-of-band management port)
connection, you must first configure the switch with an IP address and subnet mask compatible
with your network.
Also, you should configure 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 their
default settings or you can configure them with new values.
You can configure many other switch features through the switch’s console interface to:
• Optimize switch performance
• Enhance control of network traffic
• Improve network security
• Enable stacking
After you configure an IP address on the switch, you can manage these features more conveniently
in any of the following ways:
• A remote Telnet session
• A web browser interface
• An SNMP network management station running a network management program, like IMC.
For a list of switch features available with and without an IP address, refer to “How IP Addressing
Affects Switch Operation” in the Management and Configuration Guide on the Hewlett Packard
Enterprise website.
For more information on IP addressing, refer to “IP Configuration” in the Management and
Configuration Guide.
NOTE: 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 configuration method described in
“Minimal Configuration Through the Console Port Connection”, see “DHCP/Bootp Operation” in
the Management and Configuration Guide on the Hewlett Packard Enterprise website.
Minimal Configuration Through the Console Port Connection
The quickest and easiest way to minimally configure the switch for networked management and
password protection is to use the direct (out-of-band) connection through the console port to
start a console session and access the Switch Setup screen.
1. Configure a management console as described in “ Configuring the Management Console”
(page 44).
58 Getting Started With Switch Configuration
Page 59
2. Set up a console connection through the Console port by following the procedure described
in Setting Up a Console Connection. The 3810M command-line prompt should be displayed
on the console screen, typically with the switch model number; for example: Aruba 3810M#
3. At the prompt, enter the setup command to display the Switch Setup screen. The following
illustration shows the Setup screen with the default settings.
Figure 35 Example CLI switch setup screen
4. Use the Tab key to select the Manager Password field and enter a manager password.
5. Tab to the IP Config (DHCP/Bootp) field and use the Space bar to select the Manual option.
6. Tab to the IP Address field and enter the IP address that is compatible with your network.
7. Tab to the Subnet Mask field and enter the subnet mask for your network.
8. Press Enter, then S (for Save).
The following fields are displayed in the Setup screen. For more information on these fields, see

Stacking
Stacking is enabled by default, but if the switch was powered on for the first time and a stacking
module is not installed, it becomes disabled and that configuration change is saved in the switch’s
running configuration. In that case, for the stacking feature to operate, stacking must first be enabled.
From the config context in the CLI, enter the command stacking enable.
Set to Manual unless a DHCP/Bootp server is used on your network to
configure IP addressing.
Recommended; If you set IP Config to Manual, then enter an IP address
compatible with your network.
Where to Go From Here: Networked Connections
After the Switch is configured with a Manager password, IP address, and subnet mask, you can
manage the switch from a networked connection, such as:
• PC equipped with Telnet (see “Starting a Telnet Session” on Starting a Telnet Session).
• Web browser interface (see “Starting a Web Browser Session on Starting a Web Browser
Session).
• SNMP-based network management station using a tool like IMC.
For more information on these management interfaces and all the features that you can configure
on the switch, refer to the Management and Configuration Guide for your switch on the Hewlett
Packard Enterprise website.
60 Getting Started With Switch Configuration
Page 61
The following types of networked connections are supported on a 3810M Switch:
• Out-of-band networked connection through the dedicated Management port
To use: Connect an RJ-45 network cable to the Mgmt port to manage a 3810M Switch
through Telnet from a remote PC or UNIX workstation.
To use this port, the switch must have an IP address. IP settings can be configured through
a Console port connection (see Minimal Configuration Through the Console Port Connection)
or automatically from a DHCP/Bootp server.
A networked out-of-band connection through the Mgmt port allows you to manage data
network switches from a physically and logically separate management network.
For more information, refer to the “Network Out-of-Band Management (OOBM)” appendix
in the Management and Configuration Guide at http://www.hpe.com/networking/support.
• In-band networked connection through a data port on the switch
To use: Connect a PC or UNIX workstation with a VT-100 terminal emulator directly to a
switch data port. Then access the switch via Telnet from the workstation
To use Telnet, the switch must have an IP address. IP settings can be configured through
a Console port connection (see Minimal Configuration Through the Console Port Connection)
or automatically from a DHCP/Bootp server.
For more information on in-band and out-of-band networked connections for switch
management, refer to Using the IP Address for Remote Switch Management and the
Management and Configuration Guide for your switch at http://www.hpe.com/networking/
support.
NOTE: A 3810M switch can simultaneously support one out-of-band serial console session
through the console port and up to six in-band Telnet/TCP (networked) sessions through the
dedicated Management port or data ports on the switch.
Using the IP Address for Remote Switch Management
The switch’s IP address can be used to manage the switch from any PC on the same or on a
different subnet as the switch. In a networked (in-band or out-of-band) connection, you can use
a Telnet session or a standard web browser to manage the switch.
Starting a Telnet Session
To access the switch through a Telnet session, follow these steps:
1. Make sure the switch is configured 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 3810M#
Enter help or ? to see a list of commands that can be executed at the prompt. Entering any
command followed by help provides more detailed context help information about the command.
Entering any command followed by ? displays a list of options that are available at that point in
the command entry.
Starting a Web Browser Session
The 3810M Switch can be managed through a graphical interface that you can access from any
PC or workstation on the network by running a web browser and typing in the switch’s IP address
Using the IP Address for Remote Switch Management 61
Page 62
as the URL. No additional software installation is required to make this interface available; it is
included in the switch’s onboard software.
The following illustration shows a typical web browser interface screen.
Figure 36 Web browser interface screen
For more information on using the web browser interface, see the Management and Configuration
Guide, which is on the Hewlett Packard Enterprise website at http://www.hpe.com/networking/
support.
An extensive help system is also available for the web browser interface. To access the help
system, the subnet on which the switch is installed must have access to the Internet, or IMC
needs to be installed on a network management station that is on the subnet.

4 Replacing Components
This chapter shows you how to remove and install the following components:
• Fan tray (see Replacing the Fan Tray)
• Power Supply (see Replacing the Power Supply)
• Stacking Module (see Replacing the Stacking Module)
• Flex Port Module (see Replacing the Flex Port Module)
CAUTION: The 3810M switches and its components are sensitive to static discharge. Use an
antistatic wrist strap and observe all static precautions when replacing components.
CAUTION: 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.
Hot Swapping:
• The fan tray can be hot swapped. The switch does not need to be powered off to replace
the fan tray. However, it needs to be done quickly before the switch shuts down (within 2
minutes).
• The stacking module is not hot swappable. The switch must be powered off before installing
or replacing the module.
Replacing the Fan Tray
The fan tray is hot swappable. Replacing the fan try can be done with the switch powered on.
When a fan fails the Fan Status LED on the switch will blink simultaneously with the switch Fault
LED. In this case, the entire fan tray needs to be replaced. Individual fans cannot be replaced.
To replace a fan tray:
1. Remove the new fan tray assembly from it’s packaging.
2. Unscrew the retaining screw of the failed fan tray.
3. Holding the handle, pull the failed fan tray assembly straight out.
4. Insert the new fan tray assembly fully. The face plate of the fan tray will be flush with the
back face of the switch.
5. Engage the retaining screw and tighten. Be sure to not over tighten the screw.

5 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 the
switch using the software tools available with the switch, including the full-featured console
interface, the built-in web browser interface, and IMC, the SNMP-based network management
tool. For more information, see the chapter “Troubleshooting” in the 3810M Management and
Configuration Guide, which is on the Hewlett Packard Enterprise website at http://www.hpe.com/
networking/support. You may want to bookmark this Web page for easy access in the future.
This chapter describes the following:
• Basic Troubleshooting Tips (see “ Basic Troubleshooting Tips” (page 68))
• Diagnosing with the LEDs (see “ Diagnosing with the LEDs” (page 69))
• Proactive Networking Tools (see “ Proactive Networking” (page 76))
• Hardware Diagnostic Tests (see “ Hardware Diagnostic Tests” (page 77))
• Restoring the Factory Default Configuration (see “ Restoring the Factory Default
Configuration” (page 78))
• Downloading New Switch Software (see “ Downloading New Switch Software” (page 79))
• Hewlett Packard Enterprise Customer Support Services (see “Hewlett Packard Enterprise
Customer Support Services” (page 79))
Basic Troubleshooting Tips
Most problems are caused by the following situations. Check for these items first when starting
your troubleshooting:
• Connecting to devices that have a fixed full-duplex configuration. The RJ-45 ports are
configured as “Auto”. That is, when connecting to attached devices, the switch will operate
in one of two ways to determine the link speed and the communication mode (half duplex
or full duplex):
◦ If the connected device is also configured to Auto, the switch will automatically negotiate
both link speed and communication mode.
◦ If the connected device has a fixed configuration, 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 fixed configuration at full duplex, the device will not connect correctly
to the switch. The result will be high error rates and very inefficient communications between the
switch and the device.
Make sure that all the devices connected to the switch are configured to auto negotiate, or are
configured to speed and duplex settings matching those configured on the corresponding switch
port.
• Faulty or loose cables. Look for loose or obviously faulty connections. If they 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 appendix B, “Cables and
68 Troubleshooting
Page 69
Connectors” for pinouts and correct cable wiring. A category 5 or greater cable tester is a
recommended tool for every 100Base-TX and 1000Base-T network installation.
• Check the port configuration. A port on your switch may not be operating as expected
because it is administratively disabled in the configuration. 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’s configuration and verify that there is not an
improper or undesired configuration of any of the switch features that may be affecting the
port. For more information, see Management and Configuration Guide for your switch at
http://www.hpe.com/networking/support.
Diagnosing with the LEDs
• Switch LED Error Indicators shows LED patterns on the switch that indicate switch problem
conditions.
• Stacked Switch and Stacking Module LED Error Indicators shows LED patterns on the
switches and on stacking modules in a stack that indicate stack-related problem conditions.
1. Check in the tables for the LED pattern you see on your switch and stacking module.
2. Refer to the corresponding diagnostic tip on the next few pages.

If the port is a pluggable SFP/SFP+ unit, verify it is one
of the pluggables supported by the switch. Unsupported
pluggables will be identified with this fault condition.
Caution: Use only supported genuine Hewlett Packard
Enterprise transceivers with your switch.
To verify the port has failed, try removing and
reinstalling the SFP/SFP+. You can do that without
having to power off the switch. If the port fault indication
reoccurs, you will have to replace the SFP/SFP+ unit.
Try the following procedures:The network connection is not working properly.6
• 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 you have used the correct cable type for the
connection:
◦ For twisted-pair connections to the fixed 10/100
or 10/100/1000 ports, if the port is configured to
“Auto” (auto negotiate), either straight-through or
crossover cables can be used because of the
switch’s “Aruba Auto-MDIX” feature and the Auto
MDI/MDI-X feature of the 10/100/1000-T port.
Diagnosing with the LEDs 71
Page 72
SolutionProblemTip
NOTE: If the switch port configuration is
changed to one of the fixed configuration
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 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.
• For 1000Base-T connections, verify that the network
cabling complies with the IEEE 802.3ab standard.
the cable should be installed according to the
ANSI/TIA/EIA-568-A-5 specifications. Cable testing
should comply with the stated limitations for
Attenuation, Near-End Crosstalk, Far-End Crosstalk,
Equal-Level Far-End Crosstalk (ELFEXT), Multiple
Disturber ELFEXT, and Return Loss.
The cable verification process must include all patch
cables from any end devices, including the switch,
to any patch panels in the cabling path.
The port or remote link partner may be improperly
7
configured, or the port may be in a “blocking” state by
• 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, or IMC network management
software 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 “Auto”, the port on
the attached device also MUST be configured as
“Auto”. Depending on the port type, twisted-pair or
fiber-optic, 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.
• You must ensure that the device at the other end of
the connection indicates a good link to the switch.

Tree, LACP, or GVRP features.
A redundant power supply has experienced a fault.8
If it does not, the problem may be with the cabling
between the devices, the connectors on the cable,
or the configuration of the device on the remote end
of the cable.
• Use the switch console to check the port’s
configuration to confirm whether the port is
administratively disabled or placed in a “blocking”
state by the normal operation of one or more
protocols.
◦ Check the Port Status using the show interfaces
command to confirm whether the port is
configured as “disabled”.
◦ Review the switch configuration to confirm which
protocols are operating on the port. Use the
appropriate feature show commands to confirm
whether the port is put into a “blocking” state.
• For software troubleshooting tips, see the chapter
“Troubleshooting” in the Management and
Configuration Guide for your switch at http://
www.hpe.com/networking/support.
At least one power supply must be operating properly.
Check the power supply to make sure it is plugged in
to an active power source. If this is ok but the LEDs are
still blinking, the power supply may have failed. Unplug
the power supply, wait for 5 seconds for residual charge
to dissipate, and then plug the power supply. If the fault
light is still blinking, replace the power supply.
The switch has overheated.9
The port may have an internal hardware failure. The
10
port may be denied PoE power. The port may be
detecting an external PD fault.
A redundant power supply is not connected to an
11
active AC power source.
Check to ensure the fans are functioning correctly. See
Environmental for more information.
Check the port for a hardware failure, this may require
a reboot of the switch. Check the port for correct PoE
configuration and allocation. Also check the external
PD for a fault.
(At least one power supply must be operating properly.)
Connect the unplugged power supply to an AC power
source, using a supported power cord for your
country/region.

Proactive Networking
The 3810M switches have built-in management capabilities that proactively help you manage
your network, they include:
• finding and helping you fix the most common network error conditions (for example, faulty
network cabling, and non-standard network topologies)
• informing you of the problem with clear, easy-to-understand messages
• recommending network configuration changes to enhance the performance of your network

Page 77
The following interfaces provide tests, indicators, and an event log that can be used to monitor
the switch and its network connections and to help you take advantage of these proactive
networking features:
• IMC - an SNMP-based network management tool that is included with your switch.
• A graphical web browser interface that you can use to manage your switch from a PC running
a supported web browser, for example Microsoft Internet Explorer, and Netscape
Communicator.
• A full-featured easy-to-use console interface that you can access by connecting a standard
terminal or PC running a terminal emulator to the switch’s console port. The cable to make
that connection is provided with your switch. The console interface is also accessible through
a Telnet connection.
For more information on using these software tools to diagnose and manage your switch, see
the “Troubleshooting” chapter in the Management and Configuration Guide for your switch at
http://www.hpe.com/networking/support.
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 perform its
power-on self test, which almost always will resolve any temporary operational problems. 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” on “ Diagnosing with the LEDs” (page 69) for information on
interpreting the LED patterns and LED behaviors in chapter one.
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 7, “Connect a Console to the Switch”, connect a PC running
a VT-100 terminal emulator program or a standard VT-100 terminal to the switch’s Console Port
and configure it to run at 9600 baud, and with the other terminal communication settings shown
on “ Configuring the Management Console” (page 44). 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 log command, or from the console Main Menu.
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 qualified cable test device.
Hardware Diagnostic Tests 77
Page 78
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 Management and Configuration Guide for your switch at http://
www.hpe.com/networking/support.
These tests can also be performed from an SNMP network management station running a
program that can manage the switch, for example, IMC.
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.
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 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 configuration
including deleting the IP address, if one is configured.
NOTE: This process removes all switch configuration changes you have made from the factory
default settings. This includes, for example, configuration of VLANs, Spanning Tree, trunks, and
stacking. 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. For information on saving and restoring
the configuration, see the Management and Configuration Guide for your switch at http://
www.hpe.com/networking/support.
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 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 flash orange (after approximately 5 seconds),
release the Clear button.
The switch will then complete its boot process and begin operating with its configuration
restored to the factory default settings.
78 Troubleshooting
Page 79
To restore the factory default configuration using the console, execute the erase startup-config
command from the console command prompt.
For stacked switches, reset stacking configurations to factory defaults by executing the stacking
factory-reset command.
Downloading New Switch Software
Software Updates can be downloaded to the switch through several methods. See “Support and

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 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 Crosstalk (NEXT), and Far-End Crosstalk (FEXT).
Additionally, unlike the cables for 100BASE-TX, the 1000BASE-T 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.
Note on HP Smart Rate 2.5 Gb/s Cable Requirements
The 2.5 Gb/s Smart Rate operates on cable installations that are designed to support 1000BASE-T
operation. The cabling installation must meet the 1000BASE-T link segment characteristics
described in IEEE 802.3-2012 and additionally the Category 5e or Class D limits described in
the ANSI/TIA/EIA 568-C.2 and ISO/IEC 11801 standards, respectively.
Note on HP Smart Rate 5Gb/s Cable Requirements
The 5 Gb/s Smart Rate operates on the majority of Category 5e and Category 6 cable installations.
Category 5e or Class D installations must meet the ANSI/TIA/EIA 568-C.2 or ISO/IEC 11801
transmission parameter limits extended to 200MHz. Category 6 or Class E installations must
meet their respective transmission parameter limits as described in ANSI/TIA/EIA 568-C.2 or
ISO/IEC 11801.
Also, to transmission performance, 5 Gb/s Smart Rate can be sensitive to alien noise from other
cables in close proximity or background noise from the environment. Therefore, cabling must
additionally be tested for Alien Near-End Crosstalk (ANEXT) and Alien Equal-Level-Far-End
Crosstalk (AELFEXT). Depending on the cabling installation, the magnitude of alien crosstalk
may further limit the maximum supported cabling distance.
It is recommended that cable dressing be done carefully and in compliance with recommendations
in the TIA TSB-155-A and ISO/IEC TR-24750.
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
86 Cabling and Technology Information
Page 87
the data cables. It is recommended that cable dressing be done carefully and in compliance with
recommendations in the TIA TSB-155A.
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 3810M switches
are limited to Performance Criteria A with shielded cables (CAT6/6A).

Cat 5e cabling requires testing to 200 MHz operation and additionally for ANEXT and AELFEXT. The maximum
supported distances may be reduced depending on alien crosstalk levels. The support for untested cable installations
is best-effort.
2
Cat 6 cabling requires testing for ANEXT and AELFEXT. The maximum supported distances may be reduced
depending on alien crosstalk levels.
3
Cat 6 cabling requires TIA TSB-155A testing for 500 MHz operation and ANEXT.

For distances less than 20km, a 10dB attenuator must be used. For distances between 20km and 40km, a 5dB
attenuator must be used. Attenuators can be purchased from most cable vendors.
Mode Conditioning Patch Cord
The following information applies to installations in which multimode fiber-optic cables are
connected to a Gigabit-LX port or a 10-Gigabit LRM 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 Gigait-LX or
10-Gigabit LRM 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.
88 Cabling and Technology Information
Page 89
NOTE: Most of the time, if you are using good quality graded-index multimode fiber cable that
adheres to the standards listed in Cabling Specifications, 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.
For 10-Gigabit LRM using OM3 cable (50 μm multimode @ 1500/500 MHz*km), a mode
conditioning patch cord is not required. Other multimode cables may require mode conditioning
patch cords to achieve the LRM maximum distances.
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 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.
Figure 41 Connecting a Mode Conditioning Patch Cord for Gigabit-LX
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).
Twisted-Pair Cable/Connector Pin-Outs
Auto-MDIX Feature:
The 10/100/1000-T ports support the IEEE 802.3ab standard, which includes the “Auto MDI/MDI-X”
feature. In the default configuration, “Auto”, the ports on the Switch 3810M 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.
If you connect a 3810M switch twisted-pair port to another switch or hub, which typically have
MDI-X ports, the 3810M 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 3810M switch port operates
as an MDI-X port. In all cases, you can use standard straight-through cables or crossover cables.
Installing the Patch Cord 89
Page 90
If you happen to 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.
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). See “Pin Assignments” later in this appendix for a listing of the signals used on each
pin.
• For 1000Base-T connections, all four pairs of wires in the cable must be available for data
transmission. See Note on 1000BASE-T Cable Requirements for more information on
1000Base-T cabling.
• 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.
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 fixed configuration, for example 100 Mbps/Full Duplex, the ports
operate as 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 fixed configuration, 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.
