3.6 Power Supply
The CSE-745BTS-R1K23BP3 chassis supports redundant 1200W Titanium Level power
supplies (p/n PWS-1K23A-SQ). Each power supply has an auto-switching capability, which
enables it to sense and operate at a 100V-240V input range. If one of the power supply fails,
the other power supply will take on the full load. A failed power supply can be replaced while
the server is running. Replacement units can be ordered directly from Supermicro.
Replacing a Power Supply
1. Remove the AC power cord from the failed power supply.
2. Press and hold the release tab while pulling the power supply out of the chassis.
3. Insert a new power supply and slide it into the power bay until it clicks into place.
4. Reconnect the AC power cord to the power supply inlet and to the power source.
