Packet Gateway Port Remote Loop-around Test
(#611)
This test is destructive.
This test checks the integrity of cabling and devices external to the Packet
Gateway port hardware. Packet Gateway firmware executes this test on demand
by sending a test frame which is looped back to the Packet Gateway by a
loop-around that has been externally activated or installed at one of several
points in the external connectivity (see loopbacks A, B and C in the figure below).
The test passes when the sent and received test frames are identical. The test
fails if the sent and received test frames do not match, or if no test frame is
received prior to a time out.
If you suspect a problem in cabling or external devices, then repeat this test at
points that are progressively further from the PGATE port until either a failure
point is identified or the integrity of the entire path is verified. Certain site
configurations may require teamwork with those who maintain the off-site
transmission facilities.
FAIL The Packet Gateway circuit pack has detected a failure in the execution of the
test.
1. If the test fails repeatedly, attempt to reset the circuit pack if the other ports
on the board are not in use (Yellow LED is off). Reset the circuit pack by
issuing the busyout board UUCSS and the reset board UUCSS
commands.
2. If the test fails again, replace the circuit pack.
PASS The circuitry of the port tested is functioning properly.
