1. Open the front door of the upper rack, check the switches on the upper door of
the PWS shelf and the lightning arrester to see if they are reliable. There shall be
no stubs, wires or anything else in the slots for the rectifier module in the lower
shelf.
2. Open the front door to the BDS shelf of the rack in the middle. There shall be no
stubs, wires or anything else.
3. Open the front door to the RFS shelf of the lower rack. Connectors shall be
provided at the back of the corresponding slot of the RF module.
4. Check the connections at the rear part of the rack to see whether the BDS and
RFS cables are correctly and firmly connected, and whether connectors are
connected correctly and firmly according to the cable labels.
5. Check whether the RF cables at the rear part of the rack are correctly and firmly
connected, and whether connectors are connected correctly and firmly according
to the cable labels.
6. Open the back door of the rack and check whether the labels and the connections
are correct, whether the connections become insecure because of moving,
particularly the RF cables, and the connection between the power busbar of the
rack and the power connector on the board.
7. Check the DIP switches on the backplane for incorrect setting. Check whether
the DIP switches on the backplane of the rear part of the rack are in the right
position when necessary.
