Stacking the Switch
Switches in this series support stacking up to 8 switches together while being managed through one console
connection or MGMT connection on the master switch or 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.
Switches in the series can be physically stacked with optical fiber cables or Direct Attached Cables (DACs) with SFP+
connectors. Only the last four SFP+ ports on the Switch can be used for physical stacking.
The following stacking topologies are supported on the Switch:
• 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 because 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.
