Installing and removing a power module
(S5130-28F-EI switch)
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 "
When two power modules are installed, you can hot-swap a power module. To avoid device damage
and bodily injury, follow the procedures in
to install and replace a power
module.

Figure 15 Removal procedure
The installation and removal procedures are the same for the PSR150-A1, PSR150-A, and
PSR150-D1 power modules. This guide uses the
PSR150-A power module as an example.
