3. Unscrew any retention screws that fasten the board to the enclosure.
4. Open the ejectors fully, rotating the handles outward until the board disengages
from the midplane (
FIGURE 5-1
).
5. Begin to slide the board evenly out of the enclosure.
Before pulling the board out entirely, check for internal cabling attached to the board
that may become snagged or that needs to be disconnected before the board can be
fully removed. Disconnect cabling as necessary.
6. Install a replacement rear transition card or a filler panel to maintain the
enclosure's shielding and cooling performance.
Refer to Section 5.3.2.1, “Installing the Rear Transition Card for a Node Board” on
page 5-15 .
Caution –
Failure to cover all rear panel slots with rear transition cards or filler
panels can lead to overheating of power supplies.

5.3.2.1 Installing the Rear Transition Card for a Node Board
1. Choose an appropriate slot for the rear transition card.
Rear transition cards must be installed in-line behind the accompanying front node
board. For example, if the accompanying node board is installed in slot 11, its rear
transition card must be installed at the back of the system in slot 11.
2. Remove the filler panel, if necessary.
3. Prepare the rear transition card by opening its injector/ejector handle (
FIGURE 5-1
).
4. Carefully align the edges of the board with the card guides in the slot.
Look into the enclosure to verify correct alignment of the rails in the guides.
5. Keeping the board aligned in the guides, slide the card in until the injector/ejector
mechanisms engage the retention bar.
