3.1 RTM Hot Swap and Installation

Because of the high-density pinout of the hard-metric connector, some precautions must be taken when

connecting or disconnecting a RTM to/from an AT8940:

1 Rail guides must be installed on the enclosure to slide the RTM to the AT8940.

2 Do not force theRTM if there is mechanical resistance while inserting it.

3 Screw the faceplate to the enclosure to firmly attach the RTM to its enclosure.

4 Use extractor handles to disconnect and extract the RTM from its enclosure.

3.1.1 Installing the RTM in the chassis

To install the RTM:

1 Remove the filler panel from the slot.

2 Ensure the RTM is configured properly.

3 Carefully align the PCB edges at the bottom and top card guide.

4 Insert the RTM in the system until it makes contact with the CPU board.

5 Using both ejector handles, engage the RTM in the front board connectors until both ejectors are

locked.

6 Fasten screws at the top and bottom of the faceplate.

3.1.2 Removing the RTM from the chassis

To remove the RTM:

1 Unscrew the top and the bottom screw of the faceplate.

2 Unlock the lower handle latch.

3 Wait until the blue LED is fully ON, this mean that the hot swap sequence is ready for RTM removal.

4 Use both ejectors to disengage the RTM from the front board.

5 Pull the RTM out of the chassis.

WARNING

Always use a grounding wrist wrap before installing or removing the board from a

chassis.
