SUPERSERVER 6028TR-DTR/D72R USER'S MANUAL
6-11 Power Supply
The SuperServer 6028TR-DTR/D72R has two 1280 watt hot-plug power supply
modules to provide redundant power for the system. If either of the two power
supply modules fail, the other module will take the full load and allow the system
to continue operation without interruption.
The LED on the control panel for node A will flash slowly (about 4 seconds on and
4 off) and remain flashing until the failed unit has been replaced. Replacement units
can be ordered directly from Supermicro (see contact information in the Preface).
Removing/Replacing the Power Supply (Figure 6-16)
1. Disconnect the AC power cord from the failed module.
2. Push the colored release tab to the side and pull the power module out with
the handle provided.
3. Replace the failed power supply module with the exact same model from
Supermicro.
4. Carefully insert the new module into position in the chassis and push it in until
fully seated. You should see the LED on the rear of the module turn amber
showing that power (from the backup module) is present.
5. Reconnect the AC power cord to the new module.
