Rx Switching Procedure
The procedure requires disconnection, in turn, of the RAC ODU cables.
Test procedure
:
1.
Go to Diagnostics > Performance > Start All for the protected link. Ensure
unavailable second and errored second counts are at zero.
2.
Disconnect the primary RAC ODU cable and confirm there is no change to
the zero errored-second count in the performance screen. At this point the
secondary RAC is online Tx and Rx.
3.
Reconnect the primary RAC ODU cable, wait 30 seconds then disconnect the
secondary RAC ODU cable and confirm no change to the errored-second
count. At this point the primary RAC is online Tx and Rx
4.
On completion of the tests use the System/Controls screen to return to default
online status (primary RAC Tx and secondary RAC Rx), and if an unequal
coupler is used with a hot-standby installation, check that the online Tx is
selected for the low-loss side.
Frequency Diversity
Tx switching is hitless providing the online Tx RAC is not removed. (Both RACs
transmitting but Tx traffic synchronization is controlled by the online Tx RAC).
Rx path switching is hitless.
Tx and Rx Switching Procedure
The procedure requires disconnection, in turn, of the RAC ODU cables.
Test procedure
:
1.
Set a BER test on a trib with a loopback at the remote Node. Confirm zero
errors.
2.
Disconnect the ODU cable from the primary RAC and confirm no change to
the errored-second count. At this point the secondary RAC is carrying the Tx
and Rx traffic.
3.
Reconnect the primary RAC ODU cable, wait 30 seconds, check that its
online LED is green, then disconnect the secondary RAC ODU cable and
confirm no change to the errored-second count. At this point the primary RAC
is carrying the Tx and Rx traffic.
4.
On completion of the tests use the System/Controls screen to return to default
online status (primary RAC Tx and secondary RAC Rx).
For the online Tx RAC (default primary), removing its ODU cable also forces a
local switch to the standby Tx RAC. This will not affect the outcome of the local
Rx switch test.
