S3910-48TS/S3910-24TS
Installing the Power Supply Module
1. Take a new power module out of the package.
2. Take the plane printed with power information as the top panel of the power module. Hold the
handle of the power module with one hand, and hold the end of the power module with the other
hand. Insert it into the chassis along the guide rail steadily and slowly until a click is heard, and make
sure that it is in good contact with the power slot.
NOTE: 1. S3910-24TF switch has one built-in power supply.
2. Insert the power module steadily. Please pay attention to the direction of the power
panel to avoid wrong insertion. If the position is not proper, press the plug of the power
module and hold on to the module handle with one hand to pull it out slowly,
then re-insert it.
