4 Starting Up
4.1 Power Up
The J1 power cable assembly, Telefonix PDT P/N E54-331, and DB-9 loop-back connector, Telefonix PDT
P/N E54-345, are required to be connected to the Cabin ACe-2 to turn on when power is applied.
WARNING!
The specified voltage input range is 97 to 134 VAC, 60 – 800 Hz, single-
phase power.
DO NOT connect to 220 VAC.
The power source must supply a minimum of 20W.
The power source must be switched off via AC power disconnect,
Telefonix PDTP/N E54-319, and must be easily accessible.
Ambient temperature must be above -20 °C for the CWAP to turn on.
Power is not switched internally and the unit will boot up as soon as
power is applied.
Properly connect Telefonix PDT P/N E54-331 to the CWAP J1 connector. The power source must be
switched off via AC Power disconnect, Telefonix PDT P/N E54-319, to make sure that no voltage is present
at the terminal during the connecting procedure. Plug the DB-9 loopback connector, Telefonix PDT P/N
E54-345, to the mating connector of J1, E54-331 cable assembly.
Connect the other end of the power cord to the power source (not provided). Switch on the power source
via the AC power disconnect.
4.2 Startup process
The CWAP needs two IP addresses for network connectivity, one for the access point and one for the
Signal Interface Board (SIB). The four discrete IP strapping pins in the J3 connector are set to HIGH (+5v
DC) by pull up resistors, and can be grounded to set static IP addresses, by default the CWAP is configured
as a DHCP client, and will request two IP address from the network DHCP server. If no DHCP server
responds to the request then auto configuration will assign an address to the AP on the 169.254.0.0
255.255.0.0 network (the SIB will continue to send DHCP requests).
Note: The IP strapping bits are read by the CWAP at power up and will over-write any static IP assignment
made in the Aruba GUI. This behavior persists even when interface J3 is not connected.

4.2.1 Boot Up
4.2.1.1 SIB Boot Up
The SIB runs both the bootloader and application firmware components upon powering on the unit. There
is a two (2) second delay before the firmware loads to allow the bootloader to check for the presence of a
SIB firmware upgrade.
During startup, the firmware performs a Power On Self-Test (POST), queries the discrete pins, and reads
the SIB configuration and manufacturing data from an internal EEPROM. After the boot process completes
there is a five (5) second window in which you may be asked to enter SIB command mode by your technical
service representative. The console output of the SIB boot process is shown in Figure 3, the [Boot
Complete] prompt indicates the beginning of the five (5) second delay.
Figure 3: Example Console Output of the SIB Boot Process

Revision Date | July 10, 2017 || Document Number | UM-E71-308-01 || Rev C
4.2.1.2 Access Point (AP) Boot
Following SIB boot, the firmware boots the Aruba AP. During startup, the AP provides an auto-boot
countdown prompt that allows you to interrupt the normal startup process and access apboot mode. The
SIB firmware uses this mode to set the IP address configuration as defined by the IP strapping pins, then
starts a ten (10) second inactivity counter to allow user access to apboot.
The console output of the AP boot process is shown in Figure 4, the apboot> prompt indicates the
beginning of the ten (10) second counter.

The IAP CLI becomes available after completion of the startup process, and requires administrator
credentials to start a session. The default credentials are:
User: admin
Password: admin
After login, the privileged command mode is enabled which provides access to show, clear, ping,
traceroute, and commit commands. The configuration commands are available in the configuration
(config) mode. To move from privileged mode to the configuration mode, enter the following command at
the command prompt:
(Cabin Ace) # configure terminal
The configure terminal command allows you to enter the basic configuration mode and the command
prompt is displayed as follows:
(Cabin Ace) (config) #
Some commands in configuration mode allow you to enter into a sub-mode to configure the commands
specific to that mode. When you are in a configuration sub-mode, the command prompt changes to indicate
the current sub-mode.
You can exit a sub-command mode and return to the basic configuration mode or the privileged Exec
(enable) mode at any time by executing the exit or end command.
You can use the question mark (?) to view the commands available for your current mode.
Refer to the Aruba Instant 6.4.4.4-4.2.3.0 CLI Reference Guide, for additional information on the IAP CLI.
4.5 Connecting using Web-based GUI
You can connect to the web-based GUI by entering the Aruba AP’s IP address in a web browser, and
entering the Username and Password when prompted as shown below in Figure 5. If the IP strapping pins
have not been set, you can use the show ip interface CLI command to display the IP address that was
assigned by your DHCP server
Note: The following subsections refer to the [Aruba] IAP, or AP which shall be used interchangeably with
the CWAP. The sections are summarized from Aruba Instant documentation and training materials. For
additional information refer to the Aruba Instant 6.4.4.4-4.2.3.0 User Guide.
Figure 5: Aruba Instant GUI Login Prompt
You may see a Certificate Error message, this is because the certificates issued to the AP do not match
the IP address used to connect to the GUI. It is recommended that you add a certificate issued by your
network, to ensure secure administrative communication.
The main GUI page is broken up into the following six sections. These sections are identified below in
Figure 6.
1. Networks – Show all the wireless networks associated with this cluster.
2. Access Points – Shows all the access points in the cluster, the * indicates the Virtual Controller.
3. Clients – Shows all the clients connected to access points in this cluster.
4. Instant AP information – Basic information on the Virtual Controller of this cluster.
5. RF Dashboard – Gives you a view of all clients RF signals and other issues.
6. Usage Trends – Shows all the clients and throughput generated by all the clients on this cluster.

4.6 Virtual Controller Architecture
The Aruba IAPs use a Virtual Controller architecture for ease of deployment and centralized wireless
network management. IAPs in the same subnet will form a cluster, in each cluster a virtual controller is
elected. Normally the first IAP in the subnet will become the virtual controller. If the IAP running the virtual
controller should fail, then another IAP will elect itself as the virtual controller.
All configuration is done on the virtual controller and pushed down to all the IAPs in the cluster. All the IAPs
in the cluster will advertise the same SSIDs. Zones can be created within a cluster to specify specific SSIDs
on specific IAPs.
Entering the IP address of any access point in the cluster will redirect you to the virtual controller. You can
set the name of the virtual controller along with the virtual controller static address from the General tab of
the System dialog box, as show in Figure 8 below. The name and the IP address of the virtual controller
will always be static information no matter which IAP becomes the virtual controller.

4.6.1 IAP Configuration
On the main GUI page you can select one of the IAPs and then select edit. You should give each of your
IAPs a relevant name for easy identification. You can also select which IAP will be the preferred master.
Whichever IAP is configured as the preferred master will also become the virtual controller. If you configure
two IAPs as the preferred master then they will split the network, this is not recommended.

4.7 WLAN Setup
There are four steps to creating an SSID.
1. Select the type of SSID you want to create. The Employee and Voice selections will lead you to
802.1X and PSK authentication. The Guest option will lead you to Captive Portal
authentication.
2. Configure the Vlan and client IP assignment.
3. The
security
stage depends on your wireless LAN setting
selections.
Enterprise will give you 802.1x
selections, personal will give you PSK or WEP selections. If you select guest you will receive
captive portal options.
4. The last stage is the settings for the firewall with the user rights.
These stages are shown below in Figure 10.
Figure 10: The Four Stages to Creating an SSID
Step 1
You create SSIDs using the WLAN Wizard. You launch the WLAN Wizard by selecting New from the
Networks section on the main GUI page. This will bring up the WLAN Settings tab of the New WLAN dialog
box. The WLAN Settings tab is where you select the type of SSID you want to create, and name the SSID,
as shown below in Figure 11.

Revision Date | July 10, 2017 || Document Number | UM-E71-308-01 || Rev C
Step 2
The VLAN Tab is where you configure the VLAN assignment, and client IP assignment. There available
VLAN and client IP assignment options are shown below in Figure 12.
Figure 12: The VLAN Tab of the New WLAN Dialog Box
The two client IP assignment options are virtual controller Managed, and Network assigned.
Virtual controller managed
The client will associate and authenticate to the access point. The access point will act as a relay agent to
the virtual controller, and the virtual controller will provide and act as the DHCP server.
•
The access points will be providing DHCP for any wireless clients that connect to this SSID.
•
The SSID and IAPs will source NAT all client traffic onto the wire.
Network assigned
The client will associate and authenticate to the access point. The access points will act as a bridge and
pass the traffic without modifying the original payload. DHCP will be provided by the DHCP server on the
LAN. The APs will bridge the client traffic onto the wire without manipulating, or modifying the packets.
•
The AP will bridge the client traffic on to the wire
•
The AP turns the wireless frame into an Ethernet frame

Step 3
The Security tab is where you set the security level. There are three levels, Open, Personal, and Enterprise.
Selecting the Enterprise level allows you to configure an external RADIUS authentication server, as show
below in Figure 13.
Figure 13: Configuring an External RADIUS Server from the Security Tab of the New WLAN Dialog Box
Step 4
The Access tab is where you configure the firewall rules and user rights. The Access tab allows you to
create Network-Based rules and Role-Based rules. You also have the option to leave the SSID
Unrestricted. Figure 14 shows an example of creating a rule that denies all DNS traffic except to the DNS
server with the IP address of 192.168.10.1.

The Cabin ACe™ E71-308-01 antenna testing was performed with only one antenna transmitting for a total
of one spatial stream.
Each of the antennas was measured independently with gain readings collected for every degree.
The data from the four antennas is combined by averaging the linear gains.
Qualcomm QSPR software with Aruba supplied test settings was used to perform the antenna pattern
testing.
Tx power level was set at 15 dBm.
Test setup Horizontal plane.

7.2.7 Product Identification
The Part Number Identification Label for each CWAP LRU is located on the rear panel and contains the
following information as shown in Figure 25.
7.2.8 Finish and Color
The paint color of the CWAP is medium texture black. The bottom surface of the mounting plate is unpainted
and contains a clear, RoHS compliant coating per MIL-DTL-5541, Type II, Class 3. The unpainted surface
is provided for bonding of the CWAP enclosure to the aircraft airframe.
7.2.9 Materials
All materials used in the construction of the CWAP are inherently non-nutrient to fungus and do not support
combustion. The materials are of the best commercial quality, and will not blister, corrode, crack, soften, or
show other immediate latten defects that affect the storage, operation, or environmental capabilities of the
unit after any or all of the test specified.
Materials used in the CWAP have been selected in accordance with the appropriate flammability
requirements of Code of Federal Regulations FAR-25.853a.
7.2.10 Weight
The CWAP weighs 3.66 lbs.
7.2.11 Cooling Characteristics
The CWAP is designed with passive cooling.
•
Operational Power Dissipation: 20.0 W Max
•
Operational Power Dissipation: 13.5 W Nominal
7.2.12 Installation limitations
The CWAP is intended to be installed in the crown of the cabin to provide adequate RF coverage of the
WiFi signal. An installation where there is a potential for falling water requires a drip shield. Installations
per ARINC 628 part 7 (Stand Alone) shall always have the minimum air gap spacing as follows:
•
Bottom (G1) = 0.00”
•
Left (G2) = 1.00”
•
Right (G3) = 1.00”
•
Top (G4) = 1.00”
•
Front (G5) = 3.00”
•
Rear (G6) = 1.00”
Installations violating the above air gap spacing must be approved by Telefonix PDT engineering.
There are no minimum installation distances between CWAPs. The maximum distance shall be determined
by aircraft type and configuration and content, e.g. throughput considerations.
Radiation Hazard: Maintain a safe distance when in operation. The device should be installed to provide a
minimum distance of 27cm to nearby persons while in operation. Remove power if working within these
distances.

7.3 Grounding and Bonding
Electrical grounding and bonding of the CWAP unit follow standard avionics industry design practices,
ensuring proper grounding for electrical safety and for Electromagnetic Interference (EMI) control and
compliance.
7.4 Workmanship
Workmanship, including ANSI/IPC-A-620 soldering, is designed to meet ANSI/J-STD-002 and RTCA/DO-
254.
7.5 Safety
The CWAP is designed to meet the safety requirements of RTCA/DO-254.
7.6 Protective Devices
The CWAP contains a power line fuse that provides electrical separation between the airplane AC power
and the CWAP system in the event of a circuit upset per the recommendations of RTCA/DO-254. All
input/output signals within the CWAP contains ESD (TVS) protective Diodes and/or isolation transformers
that will provide protection from external noise/ESD/lightning. The protection devices have fail-safe
features, ensuring that any failure does not create hazardous condition to the CWAP.
The CWAP has a dual output temperature sensor to protect the internal electronics from an over-
temperature or under-temperature condition. Additionally, a separate temperature sensor is in place to
enable/disable the unit based on low ambient temperatures (below -20ºC).

8 Reliability and Maintainability
8.1 Reliability
The Mean Time Between Failure (MTBF) for the CWAP is a minimum of 200,000 operating hours calculated
using the RIAC 217+ (AIC, +30°C, 65% duty cycle, 1428 cycles per year).
8.2 Maintainability
The CWAP is considered an LRU and is repairable only by Telefonix PDT or an authorized repair facility.
Periodic maintenance of the CWAP is not required.
8.3 Mean Time to Repair (MTTR)
Repair time will not exceed 30 minutes, which entails replacement of the LRU.
8.4 Failure Detection and Fault Isolation
LED indicators located on the system enclosure provide functional status of the CWAP.
8.5 Production Testing
Production units are subjected to Environmental Stress Screening (ESS), and a production Acceptance
Test Procedure (ATP) prior to shipment. These tests are intended to ensure that all elements of the product
are functional and capable of performing at both high and low temperature extremes and that they are free
of manufacturing defects. The Acceptance Test Procedure is run pre- and post-ESS to test the functional
characteristics of the product.
