The S5560S-28F-SI, S5560S-28DP-SI, and S5130S-28F-SI switches each provide two power
module slots. One power module can meet the power requirement of the switch. You can install two
power modules on the switch for redundancy. Table 23 describes the power modules available for
the S5560S-28F-SI and S5130S-28F-SI switches.
