When the uplink port is converted to access port, Dell EMC Networking OS creates a logical peTenGigE interface based on the
10/100/1000BASE-T Ports in the PE.
There is a maximum of 4 uplink ports in a PE. The C1048P and N20xx have two standard uplink ports in the front panel, while the N30xx
have two standard uplink ports in the front panel and one expansion slot for plug-in module on the back panel. The expansion slot supports
10GBASE-T or SFP+ module and each module has two ports.

1. Plug-in module with Dual SFP+ Ports
You must enter the port-range as 1 and 2 for front-end uplink ports and 3 and 4 for uplink ports of the plug-in module in the back
panel.
NOTE: In PE, the ports in the plug-in module are numbered as 1 and 2.
For example, on a C1048P PE, the uplink ports are numbered as 1 and 2 on the front panel. But, the logical peTenGigE interface is
numbered as 1/0/49 and 1/0/50 for SFP+ port 1 and 2 respectively. Consider that the SFP+ port 1 of C1048P is connected to C9010 and
the SFP+ port 2 is unused. The unused SFP+ port 2 can be configured as access port using the stack-unit unit-id access—
ports port-range command, and a logical peTenGigE interface is created. The logical port is numbered based on the number of the
ports in the PE. On C1048P, the 10/100/1000BASE-T ports on the front panel are numbered from 1 to 48 and hence the number of
peTenGigE interface is created as 1/0/50.
The following table lists the port numbers of peTenGigE interface that are created when the uplink port is converted to access port:
