Aruba 2540 24G/48G Switch Quick Setup Guide and Safety/Regulatory Information
The switch drawings in this document are for illustration only and may not match your particular
switch model.
For switch and accessories installation information, browse to the manuals for your switch model at
www.hpe.com/networking/ResourceCenter.
Installation precautions
• 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.
4 Aruba 2540 24G/48G Switch Quick Setup Guide and Safety/Regulatory Information
Page 5
• Do not ship any switch in a rack without checking for restrictions in the
Aruba 2540 Switches Installation and Getting Started Guide
. Otherwise, you may void the switch warranty.
• Ensure the power source circuits are properly grounded, then use the power cord supplied with
the switch to connect it to the power source.
• Use only approved power cords with your Aruba Networking Product. Please see the power cord
information in the section titled Power cords on page 11
of this guide for acceptable power cords that are appropriate for this product. Failure to use
approved power cords can result in personal injury and product damage, and may void your
product warranty.
• If your installation requires a different power cord than the one supplied with the switch, 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.
• Do not install the switch in an environment where the operating ambient temperature exceeds its
specification. See the section titled Aruba 2540 Switch Safety and Regulatory Information on
page 12
.
• 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.
• Ensure the air flow around the switch is not restricted. Leave at least 3 inches (7.6 cm) for cooling
on the sides and rear of the switch. For other available air flow information, see the
Aruba 2540 Switches Installation and Getting Started Guide
, located on the Hewlett Packard Enterprise Information Library at www.hpe.com/networking/
ResourceCenter
.
Prepare for installation
1. Unpack and check included parts:
• Switch
• Accessory kit (installation hardware)
• Power cord
• Documentation kit
2. Prepare for installation.

before beginning the installation.
3. Power on and verify that self-test completes normally. An Aruba 2540 24G or 48G switch does not contain a
power on/off switch. It is turned on by connecting the AC power cord to the switch and to an AC power source.
1 Port LEDs: Off after self-test unless a network cable is
connected and the port is receiving link beat.
2 Global Status LED: Green after self-test in default
configuration.
3 Locator/Unit-Identification LED: Off after self-test.
4 Speed Mode Selected LED: Off after self-test in default
configuration.
5 PoE Mode Selected LED (Only on Aruba 2540 models that
support PoE+ operation): Off after self-test in default
configuration.
6 User Mode Selected: Off after self-test in default configuration.
4. Remove the power cord from the switch and the power source.
Mounting Aruba 2540 24-Port and 48-Port switches
Supported mounting options for the Aruba 2540 24-Port and 48-Port switches include:

• Tabletop or desktop mount
Wall-mounting or under-table mounting Aruba 2540 24G and 48G switches is not supported.
Two-post rack mounting option:
For the four-post rack-mount option, see the Aruba 2540 Switches Installation and Getting Started
Guide at www.hpe.com/networking/ResourceCenter.
1. Use a #1 Phillips (cross-head) screwdriver to attach the accessory kit brackets to the switch using the eight 8–
mm M4 screws.
2. Use the four number 12–24 screws to secure the brackets to the rack.
3. Go to Connecting the switch to the network on page 8.
Tabletop or desktop mounting option
Procedure
1. Attach the four self-adhesive pads (included in the accessory kit) to the bottom corners of the switch, and
place the switch on a secure horizontal surface.

2. Go to Connecting the switch to the network on page 8.
Connecting the switch to the network
1. (Optional) Connect an RJ-45 console cable and/or a micro-USB console cable (not included) to a VT-100
terminal or a PC (running suitable terminal emulation software).
JL448A, Aruba X2C2 RJ45 to DB9 Console Cable, can be ordered as an accessory to your
switch.
If both cables are connected, input is accepted only from the Micro USB connector. For more
information, see the information on connecting a management console in the Aruba 2540
Switches Installation and Getting Started Guide at www.hpe.com/networking/ResourceCenter.
2. (Optional) Insert transceivers.
8 Aruba 2540 24G/48G Switch Quick Setup Guide and Safety/Regulatory Information
Page 9
To ensure proper operation of your switch, use only genuine Aruba SFP/SFP+ transceivers
supported by your switch. For more information on using transceivers, see SFP/SFP+
installation notes.
3. Connect network cables.
Chapter 1 Aruba 2540 24G/48G Switch Quick Setup Guide and Safety/Regulatory Information 9
Page 10
In the factory default configuration, the switch automatically obtains its IP network settings from a
DHCP or BootP server after connecting to the network. If you do not use direct console access to
initially determine the switch IP address, you can determine the assigned IP address by inspecting
your DHCP/BootP server or by querying LLDP information from another, directly connected neighbor
switch. CLI LLDP commands for an ArubaOS neighbor switch are listed below.
For the specified port on the neighbor switch, lists the

the neighbor switch to access the Aruba 2540 switch
you are setting up).
Lists IP address and other data on all active ports on
the neighbor switch.

SFP/SFP+ installation notes
To ensure proper operation of your switch, use only the genuine Aruba SFP/SFP+ transceivers
supported by your switch. When selecting a fiber SFP device, make sure it can function at a
temperature that is not less than the recommended maximum operational temperature of the
product. Use only approved Laser Class 1 SFP transceivers.
Use only genuine Aruba SFP/SFP+ transceivers
Non-Aruba SFP/SFP+ transceivers are not supported. Use of genuine Aruba products ensures that your network
maintains optimal performance and reliability. Should you require additional transceivers, please contact an Aruba
sales representative or an authorized reseller. For transceiver support information for your switch model, see the
support matrixes in the in ArubaOS-Switch Transceiver Guide on the Hewlett Packard Enterprise Information
Library at www.hpe.com/networking/ResourceCenter.
Hot Swapping SFP/SFP+ transceivers
Supported SFP/SFP+ transceivers that you can install in your Aruba switch can be “hot swapped” – removed and
installed while the switch is receiving power. However, you should disconnect the network cables from the
SFP/SFP+ transceivers before hot-swapping them.
When you replace an SFP/SFP+ transceiver with another of a different type, the switch may retain selected portspecific configuration settings that were configured for the replaced unit. Be sure to validate or reconfigure port
settings as required.
SFP/SFP+ connections to devices with fixed speed/duplex configurations
When connecting a device to your switch port that contains an SFP/SFP+ transceiver, the speed and duplex
settings of the switch port and the connected device must match. Otherwise, you may not get a link. For some
older network devices, including some older Hewlett Packard Enterprise devices, the default speed/duplex
settings may be predefined (for example, to 1000 Mbps/Full Duplex), or otherwise set differently from the default
configuration of your switch port. Because of these default speed/duplex considerations, you should make sure
that devices connected to your SFP/SFP+ ports are properly configured. At a minimum, make sure the
configurations match.
