IMPORTANT:

The HPE 5940 48SFP+ 6QSFP28, HPE 5940 48XGT 6QSFP28, HPE 5940 48XGT 6QSFP+, HPE 5940 48SFP+ 6QSFP+, HPE 5940 32QSFP+, and HPE 5940 2-slot switches can operate correctly with only one power supply. You can install two power supplies on the switch for 1+1 redundancy.
The HPE 5940 4-slot switch can operate correctly with two power supplies. You can install four power supplies on the switches for 2+2 redundancy.
You must install two fan trays of the same model for the switch.
If an HPE 5940 48SFP+ 6QSFP+ or HPE 5940 48SFP+ 6QSFP28 switch uses 650 W power supplies, you can install two LSWM1HFANSC, LSWM1HFANSCB, LSWM1FANSC, or LSWM1FANSCB fan trays to ensure heat dissipation. If an HPE 5940 48SFP+ 6QSFP+ switch uses 300 W power supplies, you must install two LSWM1FANSC or LSWM1FANSCB fan trays to ensure heat dissipation.
