Stacking the Dell Networking S25 Switches
Avid supports stacking two Dell Networking S25 switches. The expansion slots in the Dell Networking switches
allow you to stack similar switches together into a single virtual switch. When two Dell Networking S25 switches
are stacked, you have the capability of connecting up to 48, 1 Gb clients. The stacking modules are ordered
separately and install in the back of the Dell Networking switch.
The Dell Networking stacking modules use a 12 Gb connection between the two S25 switches. Once the modules
are installed, connect the stacking cables as described in the following procedure. For more information on
stacking the Dell Networking switches, see the documentation provided by the switch manufacturer. The stacked
switch configuration uses LC connectors to connect the cables to the switch.

If using a stacked switch configuration, the 10 Gb connection from the Avid ISIS can be to either switch.
To stack Dell Networking S25 switches:
1. Install a 12 Gb stacking module into the right slot of the Dell Networking switch, similar to the process
described in
“Dell Networking S25 Switch Modules” on page 51.
2. Remove the right blank cover on the back of the that switch as you did when installing the 10 Gb module.
3. Insert the stacking module into the open slot where the blank cover was removed.
4. Secure the stacking module in the switch with the two captive thumb screws.
5. Repeat steps 2, 3, and 4 on the right slot of the second switch.
6. Connect the stacking cable from one stacking port on the top switch to one stacking port on the bottom
switch.

Either one of the ports on the stacking module can be used to connect the stacking module to the other.
Dell Networking S25 Switch — Stacking Module Configuration

The Avid default Dell Networking switch configuration automatically detects whether modules are installed or
not. You do not need to modify your switch configuration for the addition of the stacking modules.
7. Plug in the two power cords to power on your switch.
The Avid switch configuration file automatically detects the 12 Gb modules. If you need to change your
switch configuration, see
“Accessing the Dell Networking Switch” on page 57.

When connecting the 10 Gb Ethernet clients, evenly divide the number of clients between the two switches so the
network load is spread across both switches.
