Make sure that the PSUs meet the power supply requirement of the switch.

Each socket on the PEM-C20 corresponds to a PSU slot. Therefore, to ensure normal operation of
an AC PSU, you need to provide power supply to the relevant socket.
z
It is recommended to distribute PSUs in the upper and lower frames evenly on an S12518.
z
Before inserting or removing an AC PSU, make sure that the device is sturdy enough. Because the
device is relatively high, avoid incline of the device when inserting or removing a PSU.
Step1
As shown in Figure 3-10, follow the demonstration to open the front panel of the power frame upwards
with both hands.
