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.

Troubleshooting
In the case of compatible cables and transceivers, the port cannot be up, please try to modify the
port mode to adapt or force the port speed to 1/10G.
1/10G Port is not Working
1. Test network connectivity through ping.
2. If the network is reachable, try restarting the switch.
3. Check if the corresponding service is enabled.
Connecting the Switch Remotely Unsuccessfully
1. Ensure the switch ports are in the no shutdown state.
2. Check if the switch can read the DDM information.
3. Check if the port speed setting is correct.
4. Try looping the switch cable.
