Non Dell-Qualied Transceivers
The system supports Dell-qualied transceivers and only some of the non Dell-qualied transceivers.
If the system displays an error message similar to the following, the transceiver is not Dell-qualied. The Dell EMC Networking OS places
the interface in error-disabled (operationally down) state.
Apr 29 05:09:16: %S4048-ON:1 %IFAGT-2-TRANSCEIVER_UNSUPPORTED_ERROR: Transceiver in slot 1 port
50 unrecognized, putting interface in operational-down state
The following command output displays that the interface is in error-disabled state:
DellEMC#show interfaces fortyGigE 1/50
fortyGigE 1/50 is up, line protocol is down(error-disabled[Transceiver Unsupported])

Splitting 40G Ports without Reload
You can split 40G interfaces into 10G ports without reboot. You can also combine the split ports to create a 40G port without reload.
• On a device, fan-out prole constructs automatically with default 24 ports
(2,4,6,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,27,29,31) . These ports can be changed to 40G to 10G mode or vice-versa without
reload.
• When a non-supported prole release is upgraded to a supported prole release, the fan-out congured ports get automatically
included in the prole. In fan-out mode, if a system is upgraded with 25 or 26 ports, only 24 ports get upgraded to fan-out mode. The
rest of the ports are put to default 40G mode.
• In stacking, congure prole rst before provisioning for new units. Otherwise it is mandatory to reload for prole to take eect.
• If there is a mismatch in fan-out prole between master and the new member in stacking, the master re-congures the member with
its quad-mode prole, quad-mode, and stack-group conguration and then reset the member. To avoid stack split during prole
mismatch, the master does stack group congurations of the new member.
To congure the quad-port-prole, use the following command:
CONFIGURATION mode
stack-unit stack-unit number slot slot-number port port-number portmode quad
The defaults ports are:
2,4,6,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,27,29,31
To display the Fan-out capability prole, use the following show command:
show system stack-unit stack-unit number quad-port-profile
