Board Hot Swap and Installation
WARNING
• Do not touch internal components on the blade when the unit is installed and powered.
• Do not perform maintenance procedures on the blade without removing it from the chassis.
• Do not remove the blades without activating the hot-swap mechanism, because it can
damage the board.
Because of the high-density pinout of the hard-metric connector, some precautions must be taken when
connecting or disconnecting a board to/from a backplane:
• Rail guides must be installed on the enclosure to slide the board to the backplane.
• Do not force the board if there is mechanical resistance while inserting the board.
• Screw the front plate to the enclosure to firmly attach the board to its enclosure.
• Use extractor handles to disconnect and extract the board from its enclosure.
WARNING
Always use a grounding wrist wrap before installing or removing the board from a chassis.
WARNING
Pull the lower
ejector for hot-swap mechanism activation
Removing the blades prematurely can lead to device corruption or failure.
CAUTION
Removing the backing plate can damage the components on the board and may void the
warranty.
No user-serviceable parts are available under the PCB. Do not remove the face plate or backing
plate.
External airflow must be provided at all times during operation to avoid damaging the CPU. It is recommended
that you use a fan tray above or below the card rack to supply the external airflow. Unused slots should be
covered with blank filler panels to maintain airflow past the board.
Do not expose this device to rain or other moisture.
This board must be protected from static discharge and physical shock. Wear a grounded wrist strap when
servicing system components.
