Functional Test

TEST PROCEDURE FOR AIRBORNE MIDPLANE FBT TEST, 012686-001 ASSEMBLYTitus Stauffer 15 May 2006

Note: Inspect both UUT and the test equipment blade and check for bent pin and misaligned connector. If UUT or test equipment is damaged, then contact test engineer immediately.

1) Make sure that the spring-loaded barrel bolts are pulled away from the middle of the tester where the UUT is to be positioned (bolts, qty 4).

2) Place the 012686-001 midplane UUT (Unit Under Test) into the middle of the tester. Place it carefully and use the tooling pins that are provided. Also, 4 male pins on the power plates must mate to 4 holes in the UUT.

3) Allow the 4 spring-loaded barrel bolts to be pushed (by their springs) towards the middle of the UUT (from top and from bottom). These 4 pins hold the UUT in place while test / load blades are inserted and withdrawn.

4) Push the qty 4, double-wide I/O test blades (S155) into the UUT from the rear. These should occupy the top 4 of the 5 double-wide slots in the rear. The bottom one is reserved for EMMs (Enclosure Management Modules), not yet used. Use moderate force to mate the test blades to the UUT; a need for excessive force will indicate a damaged connector.

5) Push the qty 16, server test blades (S156) into the UUT from the front. Start from the lower left and work towards the lower right. Then engage the 8 top blades, again from left to right. Have a second test operator guide the mating action to insure no connectors are damaged. Use moderate force to mate the test blades to the UUT; a need for excessive force will indicate a damaged connector.

6) Insure that all 20 test blades are connected via 20-pin ribbon cables, to the TED 2744 “unifier” board. There are 22 connectors on the 2744 v/s only 20 test blades, and so 2 of the ribbon cables will need to connect to TWO (not just one) header on the 2744.

7) Turn on tester power.

8) Push the momentary switch on the TED 2744 test board to start the test. Be sure to hold the button for a few seconds (long enough for the blade “test in progress” LEDs to light, see below).

9) Observe the tester… Test time will be 1.5 minutes. Any RED, FAIL LED on any one or more blades should light the red FAIL LED on the 2744 unifier board. The green PASS LED should light only when all 20 green PASS LEDs on all 20 test blades are lit up. The “RIGHT” LED on all test blades will indicate “test in progress” during the 1.5 minutes. If this “test in progress” LED does not light, in means, bad cable or bad test blade, or the operator did not hold the “test start” button for long enough.




Functional Test Contd.

10) Observe the RIGHT ORANGE LEDs on the 16 server blades to the front of the tester. They should each turn ON for the 1.5-minute test, except each one should briefly blink OFF for 1 second, in a pattern walking across the front of the tester, from blade 1 to blade 16. If this patter is not working properly, then RN1 to RN16 (slot ID pull-downs) are probably not soldered or installed properly, on the midplane UUT. This is a temporary visual test until improved test coverage (a “ping test”) is implemented. Here is proper sequencing of the server blades as viewed from the front of the tester:

1 – 2 – 3 – 4 – 5 – 6 – 7 – 89 – 10 – 11 – 12 – 13 – 14 – 15 – 16

11) Observe the RIGHT ORANGE LEDs on the 4 double-wide I/O blades to the rear of the tester. They should each turn ON for the 1.5-minute test, except each one should briefly blink OFF for 1 second, twice for each double-wide I/O blade, in a pattern walking down the front of the tester, from blades 1 - 2 to blades 7 - 8. If this patter is not working properly, then RN17 to RN23 (slot ID pull-downs) are probably not soldered or installed properly, on the midplane UUT. This is a temporary visual test until improved test coverage (a “ping test”) is implemented. Here is proper sequencing of the server blades as viewed from the front of the tester:

1 - 23 - 45 - 67 - 8

12) When the green PASS LED lights on the 2744 unifier board, the UUT has passed

13) Power down the tester

14) Pull all test blades out far enough to access the UUT

15) Pull back the 4 spring-loaded barrel bolts

16) Pull out the UUT

17) Repeat the test process with the next UUT

FYI notes: Above test procedure is only for site pilot. Later versions of the test will be more complicated, with the use of a test host, EMMs (Enclosure Management Modules), more fans and power supplies, and diagnostics.

The red FAIL LED on the 2744 unifier will light if any blade has no power directly from the UUT (or power plates in the case of the server blades) or other power malfunction (such as a failed E-fuse), but DOES have power from other test blades, via the ribbon cables.

• Log all boards in data collection from Functional Test Results Pass / Fail.• Send all failed boards to Debug Technician.• Do not tale board off tester until it says Pass

Apply sticker after passing Functional Test
