Parameter Description

Destination 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

Switches in this series support stacking up to 8 switches together while being managed through one console

connection on the master switch, or by an IP address through the MGMT port if the master is a DGS-1520-28/52, or

by multiple IP addresses through any of the RJ45/SFP+ ports using Telnet, the Web UI, and SNMP. This cost-

effective switch provides an affordable solution for administrators to upgrade their networks using the stacking ports to

scale and stack the Switches. This increases overall reliability, serviceability, and availability.

• Duplex Chain - This topology stacks switches together in a chain-link format. Using this method, data transfer

is only possible in one direction. If there is a break in the chain, data transfer will be affected.

• Duplex Ring - This topology stacks switches in a ring or circle format where data can be transferred in two

directions. It is very resilient due to the fact that, if there is a break in the ring, data can still be transferred

through the stacking cables between switches in the stack using the alternate path.

Switches in the series can be physically stacked with optical fiber cables, standard Ethernet cables, or Direct Attached

Cables (DACs) with SFP+ connectors. Only the last 4 ports on the Switch can be used for physical stacking. Physical

stacking needs to be enabled and can be configured to support a 2-port or 4-port stacking configuration.

When the 2-port 10GBASE-T stacking configuration is used, a full-duplex speed of up to 40Gbps is used between

two switches.

• The DGS-1520-28 uses ports 25 (SIO1) and 26 (SIO2) for 2-port stacking.

• The DGS-1520-28MP uses ports 25 (SIO1) and 26 (SIO2) for 2-port stacking.

• The DGS-1520-52 uses ports 49 (SIO1) and 50 (SIO2) for 2-port stacking.

• The DGS-1520-52MP uses use physical ports 49 (SIO1) and 50 (SIO2) for 2-port stacking.

When the 2-port SFP+ stacking configuration is used, a full-duplex speed of up to 40Gbps is used between two

switches.

• The DGS-1520-28 uses ports 27 (SIO1) and 28 (SIO2) for 2-port stacking.

• The DGS-1520-28MP uses ports 27 (SIO1) and 28 (SIO2) for 2-port stacking.

• The DGS-1520-52 uses ports 51 (SIO1) and 52 (SIO2) for 2-port stacking.

• The DGS-1520-52MP uses ports 51 (SIO1) and 52 (SIO2) for 2-port stacking.

When the 4-port stacking configuration is used, a full-duplex speed of up to 80Gbps is used between two switches

using four physical ports aggregated into two virtual stacking ports.

• The DGS-1520-28 uses ports 25 (SIO1), 26 (SIO2), 27 (SIO1), and 28 (SIO2) for 4-port stacking.

• The DGS-1520-28MP uses ports 25 (SIO1), 26 (SIO2), 27 (SIO1), and 28 (SIO2) for 4-port stacking.

• The DGS-1520-52 uses ports 49 (SIO1), 50 (SIO2), 51 (SIO1), and 52 (SIO2) for 4-port stacking.

• The DGS-1520-52MP uses ports 49 (SIO1), 50 (SIO2), 51 (SIO1), and 52 (SIO2) for 4-port stacking.
