DMS-3130 Series Multi-Gigabit L3 Stackable Managed Switch Web UI Reference Guide The fields that can be configured in Copy File are described below: Parameter Source Destination Description Select the source Switch Unit ID and type of source file that will be copied here. Options to choose from are startup-config and Source File. Only after selecting the Source File option can the source file path and filename be entered in the space provided. Select the destination Switch Unit ID and type of destination file that will be copied here. Options to choose from are startup-config, running-config, and Destination File. Only after selecting the Destination File option can the destination file path and filename be entered in the space provided. Tick the Replace check box to replace the current running configuration with the indicated configuration file. Click the Apply button to initiate the copy. Click the Cancel button the discard the process. Stacking The Switch supports stacking 9 Switches together while being managed by one console connection to the console port on the master Switch, or by an IP address through the MGMT port, or by multiple IP addresses through any of the ports using Telnet, the Web User Interface, and SNMP. This cost-effective Switch provides an affordable solution for administrators to upgrade their networks using the SFP28 ports to scale and stack the Switches. This increases overall reliability, serviceability, and availability of the network. • Duplex Chain - The Duplex Chain topology stacks Switches together in a chain-link format. Using this method, data transfer is only possible in one direction and if there is a break in the chain, then data transfer will be affected. • Duplex Ring - The Duplex Ring stacks Switches in a ring or circle format where data can be transferred in two directions. This topology is very resilient because if there is a break in the ring, data can still be transferred through the stacking cables between Switches in the stack. NOTE: When stacking is enabled, the last 4 SFP28 ports are dedicated stacking ports and cannot be used for any other purposes. Only these ports connected using optical fiber cables or Direct Attached Cables (DAC) can perform stacking and they must operate at the same speed: 25 Gbps; any other types of optical modules cannot be used for stacking. NOTE: Using Duplex Ring topology is strongly recommended. Physical stacking needs to be enabled and can be configured to support 4-port stacking configuration. When the 4port stacking configuration is used through the 25G SFP28 ports, a full-duplex speed of up to 200 Gbps will be available between two Switches. The figure below illustrates how switches can be stacked in Duplex Ring formation. 85
