7.0 TROUBLESHOOTING AND FAULT DIAGNOSIS
This section describes the troubleshooting and fault diagnosis processes for the WSS
4G system. It is always recommended that should an operational issue be suspected
that you seek assistance with these procedures through Satcom Direct, details for
which can be found below.
7.1 Product Support
If an issue is encountered or suspected, it is recommended that customers and
technicians contact Satcom Direct or the applicable Service Provider.
Satcom Direct can be reached by telephone at [phone] or email at

7.2 Troubleshooting Procedures
7.2.1 Diagnostic Access
There are two physical 1000BASE-T Ethernet ports on the Aircraft Base Radio (ABR):
1) connection to the Cabin Wireless Access Point (CWAP), which is a Wi-Fi router to
connect the aircraft’s Personal Electronic Devices (PEDs) and other Wi-Fi endpoints
(e.g. sensors), to the WSS network
2) wired maintenance port which is recommended to be in an accessible location within
the cabin for direct laptop connection to the ABR.
Both the ABR-CWAP Ethernet connection and the Maintenance Ethernet port are rated
at 1000BASE-T.
Aboard the aircraft, while either on the ground (e.g. hangar) or during flight testing, the
maintenance technician’s primary interface to the ABR will be through the wireless
CWAP rather than the wired connection to the ABR’s maintenance Ethernet port. Since
the ABR is an IP-addressable endpoint, maintenance technicians with the proper
security credentials will be able to access the ABR for maintenance and diagnostic
tasks, both wireless and hardwired. During ABR installation, ABR configuration (initial
or replacement), or if for some reason the wireless access to the ABR via the CWAP is
unavailable, the ABR hardwired maintenance Ethernet port may be used.
7.2.2 Aircraft Base Radio (ABR) Status Indicators
The following chart, Figure 7.2.2-1 describes the ABR Status LED conditions to be
expected after the ABR POST is completed. Refer to section 7.2.3 for additional fault
diagnostic procedures.
