(5) System Power-up Checks
NOTE: Before proceeding, make sure that all pre power-up, mechanical, and
electrical verifications have been successfully performed and documented
using
"Installation Checklist" on page E-1.
(a) Preparation
The following tests serve primarily to confirm proper system power-up; therefore,
they can be performed while the aircraft is still in the hangar. Make sure that a
computer is available for testing.
(b) Initial Visual LED Verification
The system's Power On and Fault LEDs provide a visual status indication on the
HSD-440 Mark 2 Terminal front panel and on the optional remote panel.
To visually verify LEDs:
1. Verify that the LED indicators (at both locations) repeatedly cycle on/off when
power is applied.
2. Once the cycle has completed (~5 seconds), verify that the LED power
indicator remains illuminated.
(c) Initial Computer Power up Display
With the computer connected and configured to accept maintenance port data,
power-up the HSD-440 Mark 2 Terminal, and verify the initial power-up screen
displays, as shown in
Figure 4-20.
