Aruba 2540 24G/48G Switch Quick Setup Guide and
Safety/Regulatory Information
NOTE: The switch drawings in this document are for illustration only and may not match your
particular switch model.
NOTE: For switch and accessories installation information, browse to the manuals for your
switch model at www.hpe.com/networking/ResourceCenter.
Installation precautions
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:
•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” (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”
(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
•Console cable
•Accessory kit (installation hardware)
•Power cord
•Documentation kit
2. Prepare for installation.
CAUTION: To avoid personal injury or product damage, review the “Installation precautions”
(page 4) 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.

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:
•Rack mount
•Tabletop or desktop mount
IMPORTANT: Wall-mounting or under-table mounting Aruba 2540 24G and 48G switches is
not supported.
Two-post rack mounting option:
NOTE: 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.

3. Go to “Connecting the switch to the network” (page 8).
Tabletop or desktop mounting option
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” (page 8).
Mounting Aruba 2540 24-Port and 48-Port switches 7

Connecting the switch to the network
1. (Optional) Connect an RJ-45 console cable (included) and/or a micro-USB console cable
(not included) to a VT-100 terminal or a PC (running suitable terminal emulation software).
NOTE: 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

NOTE: To ensure proper operation of your switch, use only genuine HPE Aruba SFP/SFP+
transceivers supported by your switch. For more information on using transceivers, see
“SFP/SFP+ installation notes” (page 10).
3. Connect network cables.
Connecting the switch to the network 9

NOTE: 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 IP
address and other data for the directly connected Aruba 2540

switch (where port_# is the port used on the neighbor switch
to access the Aruba 2540 switch you are setting up).

SFP/SFP+ installation notes
NOTE: To ensure proper operation of your switch, use only the genuine HPE 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 HPE Aruba SFP/SFP+ transceivers
Non-HPE Aruba SFP/SFP+ transceivers are not supported. Use of genuine HPE Aruba products
ensures that your network maintains optimal performance and reliability. Should you require
additional transceivers, please contact an HPE Aruba sales representative or an authorized
reseller. For transceiver support information for your switch model, see the following two support
matrixes in the Hewlett Packard Enterprise Information Library at www.hpe.com/networking/
ResourceCenter:
•HPE Networking Legacy ProCurve Product Family Mini-GBIC and SFP Support Matrix
•HPE Networking Legacy ProCurve Product Family 10–GBE Transceiver Support Matrix
10 Aruba 2540 24G/48G Switch Quick Setup Guide and Safety/Regulatory Information

Hot Swapping SFP/SFP+ transceivers
Supported SFP/SFP+ transceivers that you can install in your HPE 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 port-specific 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.
