I have a G3siV11 with a couple of minor alarms EXP-INTF with error codes of 769, 770, and 1281. I did test board PCSS r 1 and it failed test 237 and test 238. Do I need to busy-out board, reset board, and release board to see if that clears them?
 
thats a good start look in the tech manual and find out though what failing those tests means... it will have a step by step troubleshooting guide.
 
Busy-out, reset, release board. Are they the only commands needed to reset a board if I need to do that in the future? I won't have to move or reconfigure any ports?
 
aslong as the board isnt bad... somtimes just pulling them out and resetting will clear it up also.
 
Code:
1. If the Active PPN Tone-Clock circuit pack is providing an invalid system
clock:
a. The EPN Expansion Interface circuit pack yellow LED blinks quickly.
(Fiber Out-of-Frame condition).
If the EPN is up, Test #238 fails on this Expansion Interface circuit
pack.
b. The PPN Expansion Interface circuit pack yellow LED blinks slowly.
(In-frame, No Neighbor condition).
Test #237 fails on this Expansion Interface circuit pack, but Test
#238 passes.
2. If the EPN Tone-Clock circuit pack is providing an invalid system clock:
a. The PPN Expansion Interface circuit pack yellow LED blinks quickly
(Fiber Out-of-Frame condition).
Test #238 fails on this Expansion Interface circuit pack.
b. The EPN Expansion Interface circuit pack yellow LED blinks slowly
(In-frame, No Neighbor condition).
If the EPN is in-service, Test #237 fails on this Expansion Interface
circuit pack, but Test #238 passes.

page 1509 is where you want to start.
 
the bad news is, after doing some reading, looks like you possibly have a fiber issue... read through starting at page 1509 and follow the troubleshooting steps... hope that helps.
