MDS Intrepid-HC HP Installation and Operation
XPIC Recovery Verification
In order to verify XPIC operation, simulate the faults described below.
1
Disconnect the IDU-RFU cable for each of the drawers (one at a time), and verify that the other
link is operating.
2
Disconnect the XPIC cable and check that the relevant alarms are generated.
3
Power down each of the drawers and verify that the other link is operating.
4
Swap the V and H cables and check that the relevant alarm is generated.
5
Mute and then un-mute one RFU at a time and verify that the other link is operating.
Note: In a 2+2 configuration, repeat each step above for each of the four coupled RFUs connected to the two
standby IDUs.
2+2 Verification
Perform the tests specified in Switching Tests in the 1+1 Commissioning Procedure section earlier in this guide.
In this case, the switch will be from a main IDU connected to the main V and main H RFUs, to the secondary
IDU connected to the coupled V and coupled H RFUs.
