• IEEE 802.11b/g operation as a wireless Air Monitor

• Compatible with IEEE 802.3af Power Over Ethernet (POE)

• Can be centrally managed, confi gured, and upgraded
through an Aruba Mobility Controller

BEFORE GETTING STARTED

Before installing your Aruba 40 wirless access point,
please ensure you have the following:

• 1 x Fast Ethernet cable of required length

• 1 x 802.3af compliant Power over Ethernet source
(PSE) - Aruba Mobility Controller or Midspan device

• 1 x Aruba Mobility Controller provisioned on the
network:

- with Layer 2/3 network connectivity your Aruba 40

- One of the following network services:

- Aruba Discovery Protocol (ADP)

- DNS server with an “A” record

(see section 1; Provisioning the Aruba 40)

- DHCP Server with vendor specifi c options

(see section 1; Provisioning the Aruba 40)
Optional:

• Mounting screws (not supplied)

The Aruba AP Setup Process

Setting up an Aruba AP typically consists of a
planning stage and three AP installation stages:

WLAN Planning — Determine how many Aruba access

points will be needed for your wireless network deployment
and where they will be installed. This can be easily accom­plished using Aruba’s automated RF Plan site-survey software
(available separately). This stage should have been completed
during the master Aruba Mobility Controller installation and
confi guration. In, typical Aruba installations, the mobility con­trollers are confi gured and installed prior to access points.

1 AP Provisioning — Provides each Aruba access point with

the initial setting required to locate the host Aruba Mobility
Controller.

Once the Aruba access point is associated to its host Mobility

Controller, device specifi c confi guration may be applied as
required (such as location code).

2 AP Installation — Once provisioned, the AP can be physi-

cally installed at its intended place of operation.

3 AP Confi guration — The administrator defi nes the opera-

tional behavior for each Aruba access point such as RF char­acteristics and security features. For specifi c access point
confi guration information, refer to the ArubaOS User Guide.

Provisioning the Aruba 40

Aruba Networks, in compliance with governmental requirements,
has designed the Aruba 40 such that only authorized network
administrators can change these settings. For more information
on Access Point confi guration, refer to the ArubaOS User Guide.

CAUTION:

Access Points are radio broadcast devices and as such are subject to
governmental regulation. Network administrators responsible for the
confi guration and operation of Access Points must comply with local
broadcast regulations. Specifi cally, Access Points must use channel
assignments appropriate to the location in which the Access Point
will be used.

Goal of Access Point Provisioning

Provisioning provides the Aruba access point with basic network
settings that allow it to locate the host Aruba Mobility Controller.
Initial provisioning may be achieved through a number of methods,
including:

- Aruba Discovery Protocol (ADP)

- DNS

- DHCP with Vendor Specifi c Options

Aruba Discovery Protocol (ADP)

This is the simplist method for AP provisioning. ADP allows Aruba
access pionts to be connected to the network (or directly to a
Aruba Mobility Controller) and brought into operation automatically.

ADP performs one key task:

Obtain the IP address of the host Aruba Mobility Control-

ler from which the Aruba access point will obtain its initial
software load and confi guration.

NOTE: Additionally, the access point software can be uploaded via a
standard TFTP server.

ADP with Directly / Layer 2 Connected Access Points

If your Aruba access point is directly connected to an active Ether­net interface on an Aruba Mobility Controller, then no confi guration
is required. You may proceed to the next step.

ADP with Layer 3 Connected Access Points

If your Aruba access point is NOT directly / Layer 2 connected to
an Aruba Mobility Controller, and IP multicast routing is enabled on
the host network, then ADP will multicast packets to locate a host
Aruba Mobility Controller’s IP address.

To ensure ADP is enabled, issue the following commands on the
Master Aruba Mobility Controller:

(A5000) (confi g) #adp discovery enable
(A5000) (confi g) #adp igmp-join enable

An IP helper address on the subnet’s default gateway, mapped to
the host Aruba Mobility Controller’s IP address can be also used to
facilitate the multicast / broadcast based aspect of this process.

Provisioning using DNS

If Layer 3 network connected, the Aruba 40 can use network
based DNS to resolve a factory confi gured default host name
“aruba-master” to derive the host Mobility Controller IP address.
To enable this, a record for “aruba-master” must be created on
the network DNS server.

Provisioning using DHCP with
Vendor Specific Options

A standards compliant DHCP server can be confi gured to
return the host Aruba Mobility Controller’s IP address through
Vendor Specifi c Options (option 43) in the DHCP reply. If the
host Mobility Controller’s IP address is obtained via DHCP, it
will be used for uploading the Aruba access point’s software
image and confi guration.

NOTE: If you have location-specifi c confi gurations for your Access Points, you will need
to apply this confi guration information using AP Reprovisioning.

AP Reprovisioning

Once an AP is associated to an Aruba Mobility Controller, it is
capable of being Reprovisioned if necessary. AP Reprovisioning
is the process by which APs are assigned unique confi guration
characteristics, for example, location codes. Location codes are
important for recalibration and triangulation. For details on AP
Reprovisioning, see the ArubaOS User Guide.

AP Provisioning

Recommended only in instances where APs require to be
pre-staged or provisioned in advance of shipment and fi nal
network installation (suchas as Remote Access Point (RAP)
deployments), in AP programming mode, AP confi guration
parameters are defi ned on the Aruba Mobility Controller via
command line interface or web interface, where they can
then be uploaded to individual access points as required.

Installing the Aruba 40

Select a location as close as possible to the center of the intend­ed coverage area. The service location should be free from
obstructions or obvious sources of interference. Normally, the
higher you place an access point or air monitor, the better its per­formance.

The Aruba 40 can be mounted on a wall using the mounting
slots on the bottom of the unit.

NOTE: For dimensions, see “Product Specifi cations”. Allow 5 cm (2”) additional space
on the right-hand side for cables and ensure enough space for antenna articulation.

Using the Built-In Mounting Slots

The keyhole-shaped slots on the back of the Aruba 40 can be
used to attach the device upright to an indoor wall or shelf.

CAUTION: Do not use the mounting slots to hang the Aruba 40 from the ceiling,
sideways, or in any place where it could fall on people or equipment. For more secure
installation, use one of the optional mounting kits.

To hang the Aruba 40 upright using the mounting slots,
perform the following steps:

1 Install two screws in the wall or

shelf. If attaching the device to
drywall, we recommend using
appropriate wall anchors (not
included).

2 Align the Aruba 40 mount-

ing slots to capture the surface
screws.

3 Orient the antenna. For best per-

formance, swivel the antenna so
that it is oriented vertically.

Connecting Required Cables

NOTE: Aruba 40 Access Points are intended only for installation in Environment A as
defi ned in IEEE 802.3.af, Power over Ethernet. All interconnected equipment must be
contained within the same building, including the interconnected equipment’s associ­ated LAN connections.

The 10/100 Mbps Ethernet (FE) port is used to connect the AP
to a 10Base-T/100Base-TX (twisted-pair) Ethernet LAN segment.
Use a 4- or 8-conductor, Category 5 UTP, straight-through FE
cable.X and automatically adjusts for straight-through or cross­over cables. The maximum length for FE cables is 100 meters
(325 feet). Install cables in accordance with all applicable local
and national regulations and practices.

Connecting Cables & Power

1 Connect one end of the FE cable directly to the Aruba 40

FE port

2 Connect the other end of the FE cable to one of the

following:

- To a network port on the Mobility Controller, or

- To a network mid-span device that supports 802.3af
compliant port

FE Port Specifi cations

The 10/100 Mbps Ethernet (FE) port is located on the right-hand
side of the Aruba 40 and has an RJ-45 female connector. The
port pin-outs are shown in Figure 0-2:
