Through the embodiment shown in FIG. 9, the maximum board configuration flexibility can be obtained in the case of a limited high-speed interface, so that the system solution can be configured and modified to the greatest extent according to user requirements, and is easy to be compatible and expanded.

The invention is further explained below in conjunction with specific embodiments.

Example 1

The half-height board and the full-height board are mixed in the same slot, and the Ethernet GE network port is automatically switched.

FIG. 10 is a schematic diagram of the slot addresses 10, 17, and 30 of the subrack of the embodiment 1 of the present invention being compatible with the full height board and the half height board. A, B and X (corresponding to the connector of the embodiment shown in Fig. 5) respectively represent the common signal socket of the half-height board and the common signal socket of the full-height board. The following uses the network port as a high-speed port representative, as shown in Figure 10.

When two half-height boards are inserted, the slot addresses are 10 and 17, respectively. If the full board is inserted, the slot address is 30. Since the A and X on the left side are not compatible, it is necessary to provide two network ports - two half-height boards are compatible with one full-height board and three network ports are required.

When compatible, use the electric switch to switch the network port of the full-height board X and the net port of the half-height board B of the right slot 17. The compatibility rule uses the mutual exclusion principle that the full-height board with a slot address of 30 and the half-height board with a slot address of 17 cannot coexist. It is described as:

1. By default, the switch connects GE2 to the X of slot 30.

2. If the slot address 17 detects the card, GE2 is switched by the switch to B of the slot address 17.

3. If the board in slot address 17 is removed, GE2 is switched back to X of slot address 30.

4. GE1 is directly connected to slot A of slot 10.

Example 2

The half-height board and the full-height board are mixed with slots, and the PCIE channel is adaptively switched.

FIG. 11 is a schematic diagram of the slot address 10, 17, 30 compatible with the full height board and the half height board of the subrack of the embodiment 2 of the present invention. A, B and X (corresponding to the connector of the embodiment shown in Fig. 5) respectively represent the common signal socket of the half-height board and the common signal socket of the full-height board. The following uses PCIE as a high-speed port representative, as shown in Figure 11:

When two half-height boards are inserted, the slot addresses are 10 and 17, respectively. If the full board is inserted, the slot address is 30. To support PCIE multi-channel multi-mode hybrid insertion, the backplane requires a PCIE master or a PCIE switch to provide a 4-channel access connection to the switch matrix. Slot address 10 and slot address 17 provide an X1 channel. PCIE connection, slot address 30 provides an X4 channel PCIE access or X1 channel access. In this case, PCIE full-board and half-height boards can be used for PCIE channel adaptive switching.

When compatible, the electrical switch is used to switch the full-height board X of the slot address 30, the half-height board A of the slot address 10, and the half-height board B PCIE interface of the slot address 17. The compatibility rule uses the mutual exclusion principle that the full-height board of the slot address 30 and the slot-level address 10 and the half-height board of the slot address 17 cannot coexist, which are described as:

By default, the switch matrix connects the full channel of X to the PCIE master M. The X1 channel and the X4 channel have no difference in physical connection.

If either of A or B is detected by the card, the PCIE master M is switched to A and B by the switch matrix.

If both the slot address 10 and the slot address 17 are detected and pulled out, or X is detected by the card, the PCIE master M is switched back to X by the switch matrix.

Example 3

The half-height board, the full-height board, and the double-layer full-height board are mixed with slots, and the PCIE channel is adaptively switched.

FIG. 12 is a schematic diagram of the slot address 9, 10, 17, 18, 30, 31, 60 compatible with the single-layer full-high board, the double-layer full-height board, and the half-height board in the sub-rack of the embodiment 3 of the present invention. A, B, C, D, S, L, and X represent the common signal socket of the half-height board, the common signal socket of the single-layer full-height board, and the common signal socket of the double-layer full-height board, respectively. The following uses PCIE as a high-speed port representative, as shown in Figure 12:

When four half-height boards are inserted, the slot addresses are 9, 10, 17, and 18. If two single-layer full-boards are inserted, the slot address is 30 or 31. If a double-layer full-board is inserted, the slot address is 60. To support PCIE multi-channel multi-mode hybrid insertion, the backplane requires a PCIE master or a PCIE switch to provide a 4-channel access connection to the switch matrix. The slot address is 9, the slot address is 10, and the slot is located. An X1 channel PCIE connection is provided for the address 17 and the slot address is 18, and the slot address is 30 or the slot address is 31 to provide an X1 channel PCIE access. The slot address is 60 to provide an X4 channel or X1 channel access. At this time, PCIE double-layer full-height board and half-height board can implement PCIE channel adaptive switching.

When compatible, the method of switching the PCIE interface of the full-height board X and the interface of the half-height board B with the slot address of 17 is adopted. The compatibility rule uses the mutual exclusion principle that the full-height board with a slot address of 30 and the half-height board with a slot address of 17 cannot coexist. It is described as:

By default, the switch matrix connects the full channel of the double-layer full-high board X to the PCIE master M, and the X1 channel and the X4 channel are indistinguishable in physical connection. .

If any one of A, B, C, and D is detected by the plug-in board, the PCIE master M is switched to the corresponding half-height board slot by the automatic matching.

If any one of S or L is detected to be plugged and unplugged, the PCIE master M is switched to the corresponding single-layer full-board slot by the automatic matching.

If A, B, C, D, S, and L are all detected and pulled out, or the X board is detected, the PCIE master M is switched back to X by the switch matrix.
