Frequently Asked Questions - DES-3350SR D-LINK
How do I access the web management interface of the DES-3350SR?
Connect your computer to any Ethernet port on the switch. Set your PC to an IP address in the same subnet as the default IP (e.g., 10.90.90.90). Open a web browser and enter the switch's IP address. The default login is admin with no password for the first time.
Can the DES-3350SR be mounted in a standard server rack?
Yes, the switch is 1U rack-mountable. Use the included rack-mount kit and follow the instructions in the manual to securely attach the switch to the rack.
How can I reset the DES-3350SR to factory defaults?
With the switch powered on, press and hold the Reset button on the front panel for about 6 seconds until the power LED blinks. The switch will reboot with factory settings, including the default IP address and login credentials.
Does the switch support VLAN configuration?
Yes, the DES-3350SR supports 802.1Q VLAN with up to 1024 VLAN groups. You can configure tagged and untagged ports via the web interface or CLI to segment network traffic.
What is the purpose of the combo Gigabit SFP slots?
The combo slots allow you to connect fiber-optic or Gigabit Ethernet modules. Each combo slot shares a port with a copper 10/100 port, so you can use either the copper or the SFP, but not both simultaneously.
How do I update the firmware on the DES-3350SR?
Download the latest firmware from D-Link's official website. Access the switch's web interface, go to System Utilities > Firmware Update, and upload the file. Do not power off during the update process.
Can I stack multiple DES-3350SR switches?
Yes, the DES-3350SR supports stacking of up to 8 units using dedicated stacking ports. This allows you to manage multiple switches as a single entity via the stack's IP address.
What should I do if the switch becomes very hot?
Ensure the switch is placed in a well-ventilated area and that the fans (if any) are not obstructed. Reduce the ambient temperature or improve air circulation. If overheating persists, contact support.
How do I enable port security on the switch?
Go to Security > Port Security in the web interface. Specify the allowed MAC addresses for each port or use 802.1X authentication to control access. This prevents unauthorized devices from connecting.
What is the default IP address and how do I change it?
The default IP is 10.90.90.90 with subnet mask 255.0.0.0. To change it, access the web interface, go to System > IP Settings, and enter your desired IP, subnet mask, and gateway. Save and restart the switch to apply.
