7311 Model D11 rules and maximum support
Table 2-17 describes the maximum number of I/O drawer supported

2.10.2 Consideration for 7311 Model D10 I/O drawer
It is not possible to configure the 7311 Model D10 I/O drawer in a 570 initial order. Clients who
decided to migrate p5 570 to 570 can decide to re-use 7311 Model D10 I/O drawers originally
connected to the p5 570. It requires the same connection of the 7311 Model D11 and can be
intermixed in the same loop
