Install Guide

You can connect the systems while they are powered down or up. Stacking ports are bidirectional. The S5000 supports stacking in
either a ring or a daisy-chain topology. To provide redundant connectivity, Dell Networking recommends using the ring topology when
stacking S5000 systems.
Figure 24. Stacking Topology
Connecting Two S5000 Systems
To provide backup connectivity and increased data transfer between the systems, Dell Networking recommends inserting an
additional cable between the two units, in a second stacking port.
You can use any of the SFP+ or QSFP+ ports for stacking, provided it is congured as a stacking port.
CAUTION: The S5000 does not require special stacking cables. The cables used to connect 10GbE and 40GbE data ports
are sucient.
NOTE: The port numbers in the following procedure are examples only.
1. Insert one end of the rst cable into stack port 60 in chassis 1 (bottom).
2. Insert the other end of the same cable into stack port 60 on chassis 2 (top).
3. Insert a second cable into stack port 56 on chassis 2 (top).
4. Insert the other end of the second cable into stack port 56 on chassis 1 (bottom).
