SUPERSERVER 6026TT-HT(R)F/HIBX(R)F/HIBQ(R)F USER'S MANUAL

Power Supply Failure: Redundant Power (Two Modules)

The SuperServer 6026TT-HTRF, 6026TT-HIBXRF and 6026TT-HIBQRF servers

have two 1400 Watt 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 will ﬂ ash slowly (about 4 seconds on and 4 off) and remain

ﬂ ashing until the failed unit has been replaced. Replacement units can be ordered

directly from Supermicro (see contact information in the Preface). The power supply

units have a hot-swap capability, meaning you can replace the failed unit without

powering down the system.

Removing/Replacing the Power Supply (Figure 6-8)

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.
