2.13.4 Insertion of Driver and Receiver Cards
The driver and receiver cards are live insertable and are easy to insert and
remove, although some slight side-to-side rocking action might be required.
The cards can be inserted into any slot in any order, but only one driver card
should be used at any one time. There is no bus contention damage if multiple
driver cards are in operation at the same time, this is one key benefit from using
the GTLP open-drain technology. Figure 2–29 shows the connector keying
that allows the cards to be placed on the connector in only one direction. When
inserted properly, the component side of the card faces slot 1.

Keying
Figure 2–30 shows the keying in more detail. The upper key is wider than the
lower key, preventing improper insertion.
