Installing Boards
When a micro switch is present on the
ejector lever of the board front panel, you
can only hold ejector levers inwards or
outwards while pressing the micro switch.
NOTE
CAUTION
1. Before installing a board, verify that board connectors have no scratches,
holes, or damage, the backplane has no bent pins, and the plastic cover of the
48 V power connector is not detached. If an abnormality is found, contact
Huawei engineers for help.
2. Handle boards gently to avoid damage to board connectors.
3. Wear an ESD wrist strap or ESD gloves during operations.
4. Before inserting a board into a slot, correctly align the insertion holes on
the board with the insertion guide pins on the backplane. If you feel a
blockage when inserting a board into a slot, do not use force to insert the
board. Instead, remove the board and realign the insertion holes on the board
with the insertion guide pins on the backplane. Then insert the board again.
