NOTE: If the status of a port extender is not online, communication with the attached C9010 was unsuccessful, possibly due
to a mismatch in software version (SVM) or another communication error. Wait ve minutes for an auto-upgrade of the port
extender to be performed. If the status does not change to online, contact Dell Networking support at https://www.dell.com/

for assistance. See Troubleshooting a Port Extender for more information.

PE Selection Logic
After you provision port extenders and power them on, the PEs come online according to the selection logic in the scenarios described in
this section.
• You may provision cascade ports for dierent PEs but connect the cascade ports to the same PE. In this case, only the PE with lowest
PE ID comes online. In the following example, both cascade ports 1/0 and 1/12 are cabled to the same PE. However, port 1/0 is
