CAUTION:
Provide a circuit breaker for each power module and make sure the circuit breaker is off before
installation.
The S5130-28F-EI switch provides two power module slots and comes with power module slot 1 empty
and a filler panel in power module slot 2. You can install one power module, or two power modules for
redundancy. For information about power modules available for the S5130-28F-EI switch, see "Appendix

When two power modules are installed, you can hot-swap a power module. To avoid device damage
and bodily injury, follow the procedures in Figure 17 and Figure 18 to install and replace a power
