Figure 23 Installing a power module
Removing a power module
1.
Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
2.
Remove the power cord from the power module.
3.
Use a Phillips screwdriver to loosen the captive screws on the power module until they are
completely disengaged from the chassis.
4.
Grasp the handle of the power module with one hand and pull the module part way out. Support
the module bottom with the other hand, and pull the power module slowly out of the slot along
the guide rails.
5.
Place the removed power module on an antistatic mat or put it into its original packaging bag.
6.
If you are not to install a new power module, install a filler panel in the slot.
Connecting the power cord
WARNING!
•
Provide a circuit breaker for each power cord.
•
Before connecting the power cord, make sure the circuit breaker on the power cord is turned off.
The S5560S-28F-SI, S5560S-28DP-SI, and S5130S-28F-SI switches use removable power
modules and support the PSR75-12A power module. The PSR75-12A power module supports AC or
240V high-voltage DC power input.
