Is there an InfiniBand managed selector/switch?

Question

Network administration

My regards.
It is required to find the following solution:
1. Selector/switch for InfiniBand lines.
2. For example, it has 8 (16/32/48/etc.) IB ports and allows you to remotely switch anyone to anyone, i.e. first connect lines 1-5 and 2-6, then switch 1-7, 2-8, etc. at the right time.
3. The device is not required to directly support the IB protocol, but must meet the hardware requirements, i.e. work at the required frequencies, do not introduce errors into the data stream, meet the requirements for impedance, etc.
4. The device must not add a subnet manager to the factory.
Why not a standard InfiniBand switch?
Because, I did not find something that would meet the above requirements.
Much in advance.
