Summary of the Setup Process

It is important that you verify the items listed under AP Pre-Installation Checklist before you attempt to set up and install an AP-105.

Successful setup of an AP-105 access point consists of five tasks, which must be performed in this order:

1. Verify pre-installation connectivity.
2. Identify the specific installation location for each AP.
3. Install each AP.
4. Verify post-installation connectivity.
5. Configure each AP.

Aruba Networks, Inc., in compliance with governmental requirements, has designed the AP-105 access points so that only authorized network administrators can change the settings. For more information about AP configuration, refer to the ArubaOS Quick Start Guide and ArubaOS User Guide.

Access points are radio transmission devices and as such are subject to governmental regulation. Network administrators responsible for the configuration and operation of access points must comply with local broadcast regulations. Specifically, access points must use channel assignments appropriate to the location in which the access point will be used.

Verifying Pre-Installation Connectivity

Before you install APs in a network environment, make sure that the APs are able to locate and connect to the controller after power on.

Specifically, you must verify the following conditions:

• When connected to the network, each AP is assigned a valid IP address
• APs are able to locate the controller

Refer to the ArubaOS Quick Start Guide for instructions on locating and connecting to the controller.

Identifying Specific Installation Locations

RF Radiation Exposure Statement: This equipment complies with FCC RF radiation exposure limits. This equipment should be installed and operated with a minimum distance of 13.78 inches (35 cm) between the radiator and your body for 2.4 GHz and 5 GHz operations. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. When operated in the 5.15 to 5.25 GHz frequency range, this device is restricted to indoor use to reduce the potential for harmful interference with co-channel Mobile Satellite Systems.

You can mount the AP-105 access point on a wall or on the ceiling. Use the AP placement map generated by Aruba's RF Plan software application to determine the proper installation location(s). Each location should be as close as possible to the center of the intended coverage area and should be free from obstructions or obvious sources of interference. These RF absorbers/reflectors/interference sources will impact RF propagation and should have been accounted for during the planning phase and adjusted for in RF plan.

Identifying Known RF Absorbers/Reflectors/Interference Sources

Identifying known RF absorbers, reflectors, and interference sources while in the field during the installation phase is critical. Make sure that these sources are taken into consideration when you attach an AP to its fixed location.

RF absorbers include:

• Cement/concrete—Old concrete has high levels of water dissipation, which dries out the concrete, allowing for potential RF propagation. New concrete has high levels of water concentration within the concrete, blocking RF signals.
• Natural Items—Fish tanks, water fountains, ponds, and trees
• Brick

RF reflectors include:

• Metal Objects—Metal pans between floors, rebar, fire doors, air conditioning/ heating ducts, mesh windows, blinds, chain link fences (depending on aperture size), refrigerators, racks, shelves, and filing cabinets
• Do not place an AP between two air conditioning/heating ducts. Make sure that APs are placed below ducts to avoid RF disturbances.

RF interference sources include:

• Microwave ovens and other 2.4 or 5 GHz objects (such as cordless phones)
• Cordless headset such as those used in call centers or lunch rooms

Installing the AP

Service to all Aruba Networks products should be performed by trained service personnel only.

Using the Integrated Wall-Mounting Slots

The keyhole-shaped slots on the back of the AP can be used to attach the device upright to an indoor wall or shelf. When you choose the mounting location, allow additional space at the right of the unit for cables.

1. Since the ports are on the back of the device, make sure that you mount the AP is such a way that there is a clear path to the Ethernet port, such as a predrilled hole in the mounting surface.
2. At the mounting location, install two screw on the wall or shelf, 1 7/8 inches (4.7 cm) apart. If you are attaching the device to drywall, Aruba recommends using appropriate wall anchors (not included).
3. Align the mounting slots on the rear of the AP over the screws and slide the unit into place (see Figure 4).

Using the Integrated Ceiling Tile Rail Slots

The snap-in tile rail slots on the rear of the AP can be used to securely attach the device directly to a 15/16" wide, standard ceiling tile rail.

Make sure the AP fits securely on the ceiling tile rail when hanging the device from the ceiling; poor installation could cause it to fall onto people or equipment.

1. Pull the necessary cables through a prepared hole in the ceiling tile near where the AP will be placed.
2. If necessary, connect the console cable to the console port on the back of the AP.

Hold the AP next to the ceiling tile rail with the ceiling tile rail mounting slots at approximately a 30-degree angle to the ceiling tile rail (see Figure 5). Make sure that any cable slack is above the ceiling tile.

3. Pushing toward the ceiling tile, rotate the AP clockwise until the device clicks into place on the ceiling tile rail.

Connecting Required Cables

Install cables in accordance with all applicable local and national regulations and practices.

Ethernet Ports

The RJ45 Ethernet port (ENET) supports 10/100/1000Base-T auto-sensing MDI/

MDX connections. Use these ports to connect the AP to a twisted pair Ethernet LAN segment or directly to an Aruba Controller. Use a 4- or 8-conductor, Category 5 UTP cable up to 100 m (325 feet) long.

The 10/100/1000 Mbps Ethernet port is on the back of the AP. The port has an RJ45 female connector with the pin-outs shown in Figure 6.

Figure 6 Gigabit Ethernet Port Pin-Out

Serial Console Port

The serial console port (Console) allows you to connect the AP to a serial terminal or a laptop for direct local management. This port is an RJ-45 female connector with the pinouts described in Figure 7. Connect this port in one of the following ways:

• Connect it directly to a terminal or terminal server using an Ethernet cable.
• Use a modular adapter to convert the RJ-45 (female) connector on the AP to a DB-9 (male) connector, and connect the adapter to a laptop using an RS-232 cable. See Figure 8 for connector details of the adapter.

Power Connection

The AP-105 has a single 12V DC power jack socket to support powering through an AC-to-DC power adapter.

If both POE and DC power are available, the AP uses POE even when there is not enough POE voltage available to power the AP.

Verifying Post-Installation Connectivity

The integrated LEDs on the AP can be used to verify that the AP is receiving power and initializing successfully (see Table 1). Refer to the ArubaOS Quick Start Guide for further details on verifying post-installation network connectivity.

Configuring the AP-105

AP Provisioning/Reprovisioning

Provisioning parameters are unique to each AP. These local AP parameters are initially configured on the controller which are then pushed out to the AP and stored on the AP itself. Aruba recommends that provisioning settings be configured via the ArubaOS Web UI only. Refer to the ArubaOS User Guide for complete details.

AP Configuration

Configuration parameters are network or controller specific and are configured and stored on the controller. Network configuration settings are pushed out to the AP(s) but remain stored on the controller.

Configuration settings can be configured via the ArubaOS Web UI, ArubaOS CLI, or Aruba MMS. Refer to their respective guides for further details: the ArubaOS User Guide or Aruba Mobility Management System User Guide.
