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.

Aruba 2540 24G/48G Switch Quick Setup Guide and Safety/Regulatory Information
4Aruba 2540 24G/48G Switch Quick Setup Guide and Safety/Regulatory Information

• 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.
Chapter 1 Aruba 2540 24G/48G Switch Quick Setup Guide and Safety/Regulatory Information 5

To avoid personal injury or product damage, review the Installation precautions on 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.

Chapter 1 Aruba 2540 24G/48G Switch Quick Setup Guide and Safety/Regulatory Information 7

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.
8Aruba 2540 24G/48G Switch Quick Setup Guide and Safety/Regulatory Information

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

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.
show lldp info remote port_#
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).
show lldp info remote all
Lists IP address and other data on all active ports on
the neighbor switch.
