•
The HPE 5940 48SFP+ 6QSFP28, HPE 5940 48XGT 6QSFP28, HPE 5940 48XGT 6QSFP+,
HPE 5940 48SFP+ 6QSFP+, HPE 5940 , 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.
Power supplies
CAUTION:
When the switch has power supplies in redundancy, you can replace a power supply without
powering off the switch. Make sure the power supply to be replaced is powered off before you
replace it.
