• Stacking on the device is accomplished through 10G SFP+ front-end user ports on the chassis.
• All stack units must have the same version of Dell Networking OS.
Stacking Installation Tasks
The following are the stacking installation tasks.
• Create a Stack
• Add Units to an Existing Stack
• Split a Stack
Create an Stack
Stacking is enabled on the device using the front end ports.
No configuration is allowed on front end ports used for stacking. Stacking can be made between 10G ports of two units. The stack links
between the two units are grouped into a single LAG.
Stack Group/Port Numbers
By default, each unit in Standalone mode is numbered stack-unit 1.
A maximum of two 10G stack links can be made between two units in a stack. There are four stack groups. Each 10G port is a stack group.
The front end ports accommodate 1G Ethernet, 10G SFP and SFP+.
• Ports are divided into four stack-groups (0 to 3) as shown in the following example. The stack groups must be of 10G port.
○ Stack-group 0 corresponds to port 49, stack-group 1 corresponds to port 50, so on through stack-group 3.
Figure 115. Stack-Group Assignments
You can connect the units while they are powered down or up. Stacking ports are bi-directional.
When a unit is added to a stack, the management unit performs a system check on the new unit to ensure the hardware type is
compatible. A similar check is performed on the Dell Networking OS version.
Syslog messages are generated by the management unit:
• the syslog includes the unit number, previous version, and version being downloaded.
