6-6 Installing the Air Shrouds

Air Shrouds

Air shrouds concentrate airﬂ ow to maximize fan efﬁ ciency. The SC827 chassis air

shroud does not require screws to set up. Two identical air shrouds are required,

one for each serverboard/node.

Installing an Air Shroud

Conﬁ rm that all four fans are in place and working properly1.

Place an air shroud into the serverboard drawer, positioning it behind the 2.

system fans and over the serverboard and its components.

Repeat the procedure for the remaining serverboard drawer.3.

6-7 Power Supply

The SuperServer 5026Ti-HTRF has two 920 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 for node A 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)

Disconnect the AC power cord from the failed module.1.

Push the colored release tab to the side and pull the power module out with 2.

the handle provided.

Replace the failed power supply module with the exact same model from 3.

Supermicro.

Carefully insert the new module into position in the chassis and push it in until 4.

fully seated. You should see the LED on the rear of the module turn amber

showing that power (from the backup module) is present.

Reconnect the AC power cord to the new module.5.
