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. If both cables are plugged in, the console output is echoed to both the RJ-45 and the
Micro-USB ports, but the input is only accepted from the Micro-USB port.
For more information on the console connection, see “6. (Optional) Connect a management
console” (page 23). The console can be a PC or workstation running a VT-100 terminal emulator,
or a VT-100 terminal.

Power connector
The 2540 switches do not have a power switch; they are powered on when connected to an active
AC power source. The switches automatically adjust to any voltage between 100-127 and 200-240
volts and either 50 or 60 Hz. There are no voltage range settings required.
Switch features
The features of the 2540 Switches include:
• Combinations of fixed 10/100/1000-T and SFP+ ports, as described under “Network
ports” (page 7).
• Power over Ethernet (PoE+) operation (JL356A, JL357A)—The PoE+ switches are IEEE
802.3at standard compliant and provide up 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 www.hpe.com/
networking/ResourceCenter.
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 more information, see the 2540 Management and
Configuration Guide for your switch at www.hpe.com/networking/ResourceCenter
• 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 (10/100/1000Base-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 “Cabling and technology information” (page 43) 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+ 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.
◦ Aruba AirWave—A powerful and easy-to-use network operations system that manages
wired and wireless infrastructures. For more information, go to www.arubanetworks.com/
products/networking/management/airwave.
◦ IMC (Intelligent Management Center)—An SNMP-based, graphical network management
tool that you can use to manage your entire network. Free trials of IMC can be downloaded
at http://www.hpe.com/networking/imc
.
• 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 2540 Management and Configuration Guide at www.hpe.com/networking/ResourceCenter

◦ To view and update your entitlements, and to link your contracts and warranties with your
profile, go to the Hewlett Packard Enterprise Support Center More Information on Access
to Support Materials page: www.hpe.com/support/AccessToSupportMaterials
• Low power operation:
◦ Ports on a switch may be set to operate at reduced power.
◦ Port status LEDs may be turned off.
◦ RJ-45 ports operate at reduced power if they are not connected (link partner is not
detected).

2 Installing the switch
This chapter shows how to install the switch. The Aruba 2540 switches come with an accessory kit
that includes the brackets for mounting the switch in a standard 19-inch telco rack, in an equipment
cabinet, and with rubber feet that can be attached so the switch can be securely located on a
horizontal surface. The brackets are designed to allow mounting the switch in a variety of locations
and orientations. For other mounting options contact your local Hewlett Packard Enterprise
authorized network reseller or Hewlett Packard Enterprise representative.

3. Mount the switch (“3. Mount the switch” (page 19)). The switch can be mounted in a 19-inch telco rack, in an equipment cabinet, or on a horizontal surface.
4. (Optional) Install SFP/SFP+ transceivers (“4. Installing or removing SFP/SFP+
transceivers” (page 21)). The switch has two or four slots for installing SFP/SFP+ transceivers.
Depending on where you install the switch, it may be easier to install the transceivers first.
Transceivers can be hot swapped—they can be installed or removed while the switch is
powered on.
5. Connect power to the switch (“5. Connect the switch to a power source” (page 22)). Once the switch is mounted, plug it into the main power source.
6. (Optional) Connect a management console to the switch (“6. (Optional) Connect a
management console” (page 23)). You may want 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 by using the included console cable to connect a PC to the switch’s console port.
7. Connect the network devices (“7. Connect the network cables” (page 26)). Using the appropriate network cables, connect the network devices to the switch ports.
At this point, your switch is fully installed. See the rest of this chapter if you need more detailed
information on any of these installation steps.
16 Installing the switch
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:
• 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 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 “Included parts” (page 15) 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.
• Use only the AC/DC power adapter and power cord (if applicable), supplied with the switch.
Use of other adapters or power cords, including those that came with other Hewlett Packard
Enterprise products, may result in damage to the equipment.
• 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.
• Do not install the switch in an environment where the operating ambient temperature might
exceed its specification. This includes a fully-enclosed rack. Ensure the air flow around the
sides and back of the switch is not restricted. Leave at least 3 inches (7.6 cm) for cooling for
the switches when installed in a fully-enclosed rack.
1. Prepare the installation site
Cabling Infrastructure - Ensure the cabling infrastructure meets the necessary network
specifications. See appendix A, “Cabling and technology information” (page 43) 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 3 inches (7.6 cm) of space for the twisted-pair and fiberoptic cabling.
• In the back of the switch, leave at least 1 1/2 inches (3.8 cm) of space for the power cord.
• On the sides of the switch, leave at least 3 inches (7.6 cm) for cooling.
