Procedure

LOTOs required for disconnection of step 2 signals to install splitters?
Install step 4 splitters
remove step 1 LOTO
Measure all nominally connected tunnel signals:
1. AS1 FWD
2. AS2 Load FWD
3. S Band Buncher REV
4. AS2 FWD
(How to open tunnel to make adjustments? Update tunnel connections)
LOTO of step 5 signals connections?
Install step 9 splitters
remove step 6 LOTO
Measure adjacently connected tunnel signals:
1. AS1 Load FWD
2. S Band Buncher FWD
3. AS1 REV
4. AS2 REV
(Reset tunnel connections)
