14.2 Procedure of Power-on
14.2.1 Initial Power-on
1. Open the front door of the upper rack, check whether the rectifier module of the
PWS shelf is pluggable. When the rectifier module is unplugged, it shall be
partially seated in the shelf. When the PMM is inserted into the slot, it shall be
partially seated in the shelf.
2. Open the front door to the BDS shelf of the rack in the middle, insert a board,
and then abort the insertion to make it partially seated in the shelf. Insert the fan
shelf, and then abort the insertion to make it partially seated in the shelf.
3. Open the front door to the RFS shelf of the lower rack, unplug all boards to
make them all partially seated in the shelf. Insert the RF module, connect all
cables, and make sure the switch is off.
4. AC power-on: Switch on the upper level AC power, and connect the
corresponding AC voltage for the terminal. Switch on the AC input. It is over
when the D-level lightning-proof indicators on the right corner of the front panel
are all on.
5. DC power-on: Insert a rectifier module and start it. The indicators shall present
no alarms with the current zero, and the output DC voltage 48V
∼
54V. Insert the
rectifier module in turn with the others unplugged, the indicators shall be normal.
Keep one rectifier module plugged, and insert the PMM to complete the PWS
shelf check.
6. Switch on the BDS shelf, insert and start the fan, and insert a board to complete
power-on. If the fan is not started, check for any error on the DC 48V or an ill
plugging of the fan.
7. Switch on the RFS shelf, insert and start the fan, and insert a board to complete
power-on. If the fan is not started, check for any error on the DC 48V or the fan.
8. Switch on the loop of the battery to see if it is normal. Disconnect the switch
after the power-on is complete.
9. Insert into the rectifier modules, BDS boards, RFS boards and modules in turn
to see if they are normal.
10. Switch on the loop of the battery to complete the power-on.
