A PSR300-12D1 DC power module is shipped with the S5810-50S-DC
The switch only requires one power module to ensure the normal operation of the whole system. You
can also select two power modules to implement 1+1 power module redundancy and load sharing.
When implementing 1+1 power module redundancy, you can hot plug a power module. To prevent
damage to the device and personal injury, follow the installation and removal procedures illustrated in
Figure 1-8
and
Figure 1-9
, respectively.
