Figure 127. S5000 Supported Stacking Topologies
Configuring an S5000 Switch Stack
To configure 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. Configure the stacking ports on each switch, including unit number and priority.
4. Save the stacking configuration to the startup configuration 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.
