USB Port
This port is used to connect the AP to a host computer to support application
specific functionality and for future applications in the RF environment such as
RFID tracking or spectrum analysis.
DC Power Socket
This socket is used to connect the optional AC power adapter (not included). If
POE supplying power to the Aruba 2E, the power adapter is not necessary.
Kensington Security Slot
This slot is compatible with a Kensington MicroSaver Security Cable (not
included) which can be used to prevent the unauthorized removal of the Aruba 2E
from its installed location. To secure the Aruba 2E, wrap a security cable around
an immovable object, insert the cable’s lock into the Kensington Security Slot,
and turn the key.
To use the Kensington Security Slot while the Aruba 2E is mounted by the
mounting slots, the fold-out panel must be open.
See Appendix A, “Port Specifications” for port and cable specifications.

Connecting the Console Terminal
Manual provisioning requires this procedure. You must use the serial console
breakout adapter cable to access the serial console interface to the Aruba 2E
while allowing the device to be powered by the AC adapter or POE (from an
Aruba Mobility Controller).

3. Connect the adapter’s “To Network” RJ-45 connector to the LAN.
The LAN connection is optional unless POE is being used to power the AP.
For convenience, the adapter kit includes an FE coupler to connect RJ-45
cable ends together.
4. Connect power to the Aruba 2E.
The Aruba 2E can receive electrical power using the following options:
POE–If connecting the Aruba 2E to a device that supplies IEEE 802.3af
compliant POE, no additional power connection is necessary.
Power Outlet
N
OTE: When the Aruba 2E is installed in an air-handling space, as described
in NEC (2002) Article 300.22(C), POE must be used instead of a
power outlet.
If local regulations and practices permit, connect the optional AC power
adapter (not included) to the DC power socket on the rear panel of the Aruba
2E and plug it into an appropriate power outlet.
N
OTE: The indicator LEDs on the Aruba 2E will remain dark during this
procedure.
5. Set your local terminal to use the following communications:
6. Establish console communication.
Press <Enter> a few times to establish communication between the Aruba 2 E
and terminal.
CAUTION: Be sure to comply with electrical grounding standards
during all phases of installation and operation of the AP.
Do not allow the Aruba 2E or optional power adapter (if
used) to be connected to or make contact with metal or
power outlets on a different electrical ground than the
device to which it is connected. Also, never connect the
AP to external storm grounding sources.
CAUTION: To prevent personal injury or damage to equipment,
use only the AC power adapter certified for this device
in the country where it is used.

7. From the Aruba 2E console, access the apboot prompt.
Depending on the Aruba 2E status, one of the following screens appears:
Autoboot countdown—The countdown prompt allows you to interrupt the
normal startup process and access the apboot prompt where provisioning is
performed.
To access the apboot prompt, press any key (such as <Enter>) before the timer
expires. If the countdown expires before you can interrupt it, turn the device
off and then back on.
TFTP time out—If the Aruba 2E cannot locate an Aruba Mobility Controller on
its network port, the following type of output is repeatedly displayed:
Press <Control-C> to interrupt this process and access the apboot prompt.
When the apboot prompt displays, perform provisioning (see next section).

Setting Aruba 2E Parameters
1. From the apboot prompt, configure the host information, if necessary.
In order to provide centralized management of the APs, each Aruba AP
downloads its software image and configuration files from a master Mobility
Controller.
Setting the correct host information depends on the following:
Does your network use direct IP addresses or DNS with host names?
If using host names, is aruba-master acceptable for the master Mobility
Controller, or do you need to define a different name?
Depending on your answers, select one of the following steps:
z My network uses DNS and the aruba-master host name is acceptable.
This is the default. It requires your DNS to be configured to resolve
“aruba-master” to the IP address of the master Mobility Controller. Unless
your system has been previously configured for different settings, you
can skip to Step 2.
Otherwise, if your system was previously configured for a different
setup, manually set the servername environment variable to the default
host name:
N
OTE: The master and serverip environment variables also affect how AP
source files are selected and should be cleared when using this
approach. To clear a variable, enter the setenv variable command with
no host name or address value:
apboot> setenv master
apboot> setenv serverip
When finished, proceed to Step 2.
z My network uses DNS, but I will use a different host name for the
Mobility Controller.
This requires that the servername variable be configured with your chosen
host name for the master Mobility Controller. It also requires that your
DNS be configured to resolve the specified host name to the IP address
of the master Mobility Controller.
To manually set the host name, use the following command:
apboot> setenv servername aru ba-master
apboot> setenv servername
<Mobility Controller host name>
