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

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.

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.
