Non Dell-Qualified Transceivers
The system supports Dell-qualified transceivers and only some of the non Dell-qualified transceivers.
The system supports the following cables and adapters:
● DAC cables
● AOC cables
● AOC fan-out cables
● DAC fan-out cables
● 40G fiber breakout cables
● 10G AOC and DAC cables
● 1G optics
● QSA
If you use any of the cables or adapters in the preceding list that is not Dell-qualified, the Dell Networking OS detects it and
makes it operational. The system displays a syslog message similar to the following:
Apr 29 05:09:16: %S4048-ON:1 %IFAGT-5-UNSUP_OPTICS: Non-qualified optics in slot 1 port
49
The system supports the following types of transceivers only if they are Dell-qualified:
● LR4
● SR4
● LM4
● PSM4
● PSM4-LR
If you use any of the transceivers in the preceding list that is not Dell-qualified, Dell Networking OS places the interface in error-
disabled (operationally down) state. The system displays a syslog message similar to the following:
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:
Dell#show interfaces fortyGigE 1/50

Splitting QSFP Ports to SFP+ Ports
The switch supports splitting a single 40G QSFP port into four 10G SFP+ ports using a supported breakout cable. (For the link
to a list of supported cables, refer to the C9000 Installation Guide or the C9000 Release Notes).
To split a single 40G port into four 10G ports, use the following command.
