Stack Ports
NOTE
Cisco 500 Series Stackable Managed Switch Administration Guide
Stack ports are used to connect units in the stack and to transfer data and protocol
packets among the units.
Table 2 describes the possible types of stack ports and their speeds on the
various types of devices:
If auto selection of the stack port speed is configured, the system automatically
identifies the stack cable type and selects the highest speed supported by the
cable and the port.
If auto selection of the stack port speed is not configured, all stack ports must be
set to the same speed, in order for the stack to functions correctly

SG500X S1, S2 - XG
SG500X S1, S2 - 5G
Sx500 S1, S2
Sx500 S3, S4
When a Sx500 operates in stacking mode, S1 and S2 operate as regular network
ports, and S3 and S4 operate as stack ports by default. On the SG500X, S1 and
S2 are stack ports by default. You can manually reconfigure S1/S2 and S3/S4 as
network ports or stack ports as desired. All the stack ports on a device operates in
standalone mode will automatically become regular Ethernet network ports.
The stack ports do not support 1G auto negotiation.
