NETGEAR ProSAFE GS748T Gigabit Smart Managed L3 Switch
By default, the switch IP address works as follows:
• If you cable the switch to a network with a DHCP server before you power on the switch, the DHCP server assigns an IP address to the switch when the switch is powered on.
• If you power on the switch when it is not connected to a network with a DHCP server, the switch uses its default IP address, which is 192.168.0.239. You can disable the DHCP mode in the switch and enter static IP address and subnet mask values for the switch as well as the address of the gateway device used by the switch.
To specify IP address settings for a switch using a Desktop GUI:
1. Connect your computer to the same network as the switch. You can use a WiFi or wired network connection, or connect directly to a switch that is off-network using an Ethernet cable.
2. Launch the ProSAFE Plus Utility using the desktop icon or tile. The Switch Selection page displays a list of Web Managed (Plus) switches that it discovers on the local network.
3. Select the switch. If you do not see the switch, click the REFRESH button.
4. Click the IP SETTING button.
5. In the DHCP Mode menu, select Disable. The IP Address, Subnet Mask, and Gateway Address fields are enabled.
6. Enter the IP address, subnet mask, and if available, the gateway address.
7. Enter the switch’s password in the Password field. The switch’s default password is password.
8. Click the APPLY button. Your settings are saved.
