2. Procedure (TASK 23-15-30-700-801-A01)
A. Job Setup (Subtask 23-15-30-810-001-A01)
W
ARNING: BEFORE YOU USE A MATERIAL, REFER TO THE MANUFACTURERS’ MATERIAL
SAFETY DATA SHEETS. SOME MATERIALS CAN BE DANGEROUS.
C
AUTION: DO NOT USE MATERIALS THAT ARE NOT EQUIVALENT TO HONEYWELL
SPECIFIED MATERIALS. MATERIALS THAT ARE NOT EQUIVALENT CAN
CAUSE DAMAGE TO THE EQUIPMENT AND CAN MAKE THE WARRANTY NOT
APPLICABLE.
C
AUTION: DO NOT DROP OR HIT THE SDU DURING THESE PROCEDURES. THE SDU
CONTAINS AN ASSEMBLY THAT CAN BE DAMAGED FROM INCORRECT USE.
C
AUTION: DO THESE PROCEDURES IN A CLEAN ENVIRONMENT TO PREVENT DAMAGE
TO MECHANICAL COMPONENTS.
(1) Obey the precautions.
B. BITE (Subtask 23-15-30-810-002-A01)
(1) On power up, the SDU performs a number of invasive BITE tests that are not possible during
normal SDU system operation.
(2) The failure of some of these tests will cause the equipment to go into fail safe mode and
prevent RF transmission. Once entered, safe mode cannot be exited except by fixing the
underlying condition and rebooting.
(3) The SDU implements security segregation whereby the control domain (responsible for classic
aero cockpit functionality) is separated from the data domain (responsible for Ethernet and
swift cabin functionality).
(4) The SDU will respond to a segregation failure by closing-down the user data (Ethernet and
swift RF) interfaces and reporting the condition to both the CMS and security event log
interfaces. If the SDU cannot verify that the user data (Ethernet and swift RF) interfaces are
closed then it will enter a safe mode whereby all interfaces are terminated.
C. LEDs (Subtask 23-15-30-810-003-A01)
(1) The front panel of the SDU has two LEDs to indicate unit status:
One green LED labelled “Power”
One red LED labelled “Fault”.
D. Self-Test (Subtask 23-15-30-810-004-A01)
(1) The front panel of the SDU has a recessed button labelled “Test”:
To reset the unit, press and hold the test button for 5 seconds.
To initiate self-test (when no LEDs are flashing), momentarily press the test button.
E. Unit Software Load Procedure (Subtask 23-15-30-810-005-A01)
(1) Field-loading of SDU software is not supported. All software upgrades must be accomplished
by the manufacturer.
(2) Field-loading of ORT software is supported through 615A-2 through Ethernet 3.
