Technical FAQ
Q: Does the PW501-S1 support hot-swapping?
A: Yes. In a dual-redundant configuration, the PW501-S1 can be replaced while the system is live without interrupting power to processors or I/O modules.
Q: Is the PW501-S1 compatible with older PW501-S0 base plates?
A: Generally, S1 modules are backward compatible with standard PW501 slots. However, it is recommended to check the system manual to ensure load-sharing balance in redundant pairs.
