Figure 128. S5000 Supported Stacking Topologies
Conguring an S5000 Switch Stack
To congure and bring up a switch stack, follow these steps.
1 Power down the switches stack and attach port cables to connect the ports between pairs of switches. Connect ports with the same
speed on each pair of stacked switches.
2 Power up each stack unit.
3 Congure the stacking ports on each switch, including unit number and priority.
4 Save the stacking conguration to the startup conguration and reload each stacked switch, one after another.
Stack and Cable Requirements
Before you cable a stack of S5000 switches, review the following requirements.
• You can connect up to a maximum of six S5000s in a single stack.
• Use SFP+/QSFP+ transceivers and SFP+/QSFP+ cables or direct attach cables (DACs) to connect stacking ports. Attach cables
only when stack units are powered down. Use SFP+ cables to connect 10GbE ports; use QSFP+ cables to connect 40GbE ports.
For more information, refer to the Dell Networking S5000 Installation Guide.
• Stacking is supported only with other S5000 switches. You cannot stack an S5000 switch with other S-Series switches.
• Only daisy-chain or ring topologies are supported; star and full mesh topologies are not supported.
• Stacking is not supported on Fibre Channel ports. If you install a Fibre Channel module in the switch, the following warning message
displays when you congure a stack group on Ethernet ports: % Error: Cannot configure stack group when FC
module is enabled
.
• Although you can have 10 GbE and 40 GbE links in an S5000 stack, connect ports with the same speed on each pair of stacked
switches: cable 10 GbE to 10 GbE ports or 40 GbE to 40 GbE ports.
