Install the S4810 | 27
You can connect the systems while they are powered down or up. Stacking ports are bi-directional. The
S4810 supports stacking in either a ring or a cascade topology (
Figure 4-2
). To provide redundant
connectivity, Dell Force10 recommends using the ring topology when stacking S4810 systems.
Figure 4-2. S4810 Stacking Topology
Connect Two S4810 Systems
To provide backup connectivity and increased data transfer between the systems, Dell Force10
recommends inserting an additional cable between the two units, in a second stacking port, as shown in
Figure 4-3
.
You can use any of the SFP+ or QSFP+ ports for stacking, provided it is configured as a stacking port.
. CAUTION: To connect S4810 systems, use only Dell Force10 supported stacking cables.
To connect two S4810 systems in a ring (
Figure 4-3
), starting with the S4810 at the bottom of the stack,
follow these steps:
. NOTE: The port numbers in the following procedure are examples only.
Step Task
1 Insert one end of the first cable into stack port 60 in chassis 1 (bottom).
2 Insert the other end of the same cable into stack port 52 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).
