The FAS70 or FAS90 system offers flexibility in expanding or replacing I/O modules to enhance network connectivity and performance. Adding or replacing an I/O module is essential when upgrading network capabilities or addressing a failed module.

You can replace a failed I/O module in your FAS70 or FAS90 storage system with the same type of I/O module, or with a different kind of I/O module. You can also add an I/O module into a system with empty slots.

  • Add an I/O module

    Adding additional modules can improve redundancy, helping to ensure that the system remains operational even if one module fails.

  • Replace an I/O module

    Replacing a failing I/O module can restore the system to its optimal operating state.

I/O slot numbering

The I/O slots on FAS70 and FAS90 controllers are numbered 1 through 11, as shown in the following illustration.
