3. Hot Swap and Installation
3.1 RTM Hot Swap and Installation
Because of the high-density pinout of the hard-metric connectors in Zone 3, some precautions must be taken
when connecting or disconnecting a RTM to/from an AT8242:
1 Rail guides must be installed on the enclosure to slide the RTM to the AT8242.
2 Do not force the RTM 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 front 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
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 means 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.
