Note
Do not energize the aircraft electrical system at this step.
1.3
Remove access panel 21QZ to get access to the aircraft Maintenance Panel aft of the copilot seat.
2
Prepare the Laptop Computer
2.1
Make sure that the laptop computer is correctly configured and the appropriate LAN Kit or Ethernet
cable is used, refer to AMM 12-B-45-45-00-00A-330A-A.
2.2
If available, connect the laptop computer to a power source (external power source or 230/115 VAC
aircraft power socket on the copilot sidepanel). Alternatively, make sure that the laptop computer
battery is fully charged.
3
Connect the Laptop Computer to the Aircraft LAN
3.1
Option A: Wireless Data Loading System Connection
If the aircraft has the Wireless Data Loading System installed (SB 46–004 or Factory Option), the
aircraft Maintenance Panel has one RJ-45 connector marked High Speed LAN Bus. Use a standard
CAT 5 100 Base T Ethernet cable (Pt.No. Local supply) to connect the High Speed LAN Bus RJ-45
connector on the Maintenance Panel to the laptop RJ-45 Ethernet connector.
Note
The 10 Mbit LAN is still available and can be used as a backup option (if the High Speed LAN Bus
fails). To use the 10 Mbit LAN bus, make sure that the WLAN DATA LOAD circuit breaker is open
before you energize aircraft electrical power. This will activate the 10 Mbit LAN bus. Then follow the
procedure in
3.2
Option B: 100 Mbit LAN Connection
If the aircraft is post SB 45–007 or MSN 1341 and up, and the Wireless Data Loading System option is
not installed, the aircraft Maintenance Panel has two RJ-45 connector marked NIC1 and NIC2.
3.2.1
Use the two modified Ethernet cables from the LAN Kit 100Mbit (Pt.No. T45-025). Connect the ends
marked Aircraft Side to the aircraft Maintenance Panel NIC1 and NIC2 RJ-45 connectors.
3.2.2
3.2.3
Use the standard Ethernet cable (part of the LAN Kit 100Mbit (Pt.No. T45-025)) to connect the
Ethernet switch to the laptop computer Ethernet connector.
3.2.4
Connect the Ethernet switch to a power source with the USB cable or use the power supply (included
in the LAN Kit 100Mbit (Pt.No. T45-025)).
Note
The two modified Ethernet cables must be connected before aircraft electrical power is energized. This
makes sure that the APEX avionics suite will activate the 100 Mbit network on power up.
Note
The 10 Mbit LAN is still available and can be used as a backup (if the 100 Mbit LAN fails). To use the
10 Mbit LAN disconnect the two modified Ethernet cables from the aircraft Maintenance Panel RJ-45
connectors before aircraft electrical power is energized. This makes sure that the APEX avionics suite
activates the 10 Mbit LAN network. Then follow the procedure in
as appropriate.
3.3
Option C1: 10 Mbit LAN Connection, using the LAN Kit 10Mbit (Pt.No. T45-020) or LAN Kit
LANTAP-10 (Pt.No. T45-020)
If the aircraft is pre SB 45–007 or MSN 1001 to 1341, and the Wireless Data Loading System option
is not installed, the aircraft Maintenance Panel has only one BNC connector marked LAN Bus and no
RJ-45 connectors.
