with Step 2. If the pack is or will be located on the Basic side (first
eight positions from the right) it may be “hot inserted”. Jump to
Step 3.
Warning: Failure to power down the Intelligent power board (BJJ)
when installing or removing Intelligent side packs may result in
permanent damage to the Galaxy controller.
Note: Powering down the Intelligent side will cause all rectifiers
previously held off through Energy Management or some other
program to restart, will cause all communication underway
through the Local, Aux, or Modem ports to cease, and cause the
suspension of history and statistic gathering during the power
down period. Also verify that the “Low Memory Battery” warning
is not active and replace the memory battery in the BJH Intelligent
control board if necessary prior to continuing.
2. Identify the BJJ Intelligent Power board (far left position) and pull
its circuit pack locking lever forward and downward to release it
from the backplane. Slide the pack straight out until fully
disengaged from the backplane.
3. If a circuit pack is being replaced, pull its locking lever forward
and downward to unlock the pack. Then slide the pack straight out
of the card cage. For a new circuit pack, verify that the card cage
position into which it will be installed is correct. See Figure 3-1
and Table 3-A.
4. Align the circuit pack to be installed up with the circuit pack
tracks and carefully slide the circuit pack into the card cage. Seat
and lock the circuit pack into the card cage by lifting the circuit
pack locking lever to the full upright position. If the new or
replaced pack is located on the Basic side, observe an active green
pack LED after approximately 10 seconds. If the new or replaced
pack is located on the Intelligent side, proceed to Step 5.
5. Reengage the BJJ Intelligent power board into the backplane and
lift its circuit pack locking lever into the full upright position.
Observe active green LEDs on all packs after approximately one
minute.
