Adding PCIe Cards
The server includes two pre-installed riser cards designed specifically for use in the 1U rackmount
server chassis. These riser cards support two low-profile PCI Express (PCIe) x16 cards that install
inside the chassis.
A riser card has already been preinstalled into each serverboard. The PCIe card cannot be “hot
installed”. Perform the following steps to add a PCIe add-on card:
1. Grasp the two handles on either side and pull the unit straight out of the rack until it locks
(you will hear a "click").
2. The top cover of the chassis is secured with four screws: two at the top rear of the cover and
one on each side lip, also near the back. Remove all four, then place both thumbs in the
indentations and push the cover back until it slides off.
3. Lift the top cover from the chassis to gain full access to the inside of the server.
4. Remove the PCIe slot shield on the chassis by releasing the locking tab.
5. Insert the add-on card into the riser card.
6. Secure the add-on card with the locking tab.
System Fans
Each node has three sets of 4-cm high-performance PWM fans to provide the cooling for the
system (each set consists of two back-to-back counter-rotating fans). Fan speed may be controlled
by a setting in BIOS (see Chapter 5).
System Fan Failure
If a fan fails, the red overheat/fan fail LED on the control panel will blink on and off.
Replace any failed fan at your earliest convenience with the same type and model (the system can
continue to run with a failed fan). Remove the top chassis cover while the system is still running
to determine which of the fans has failed. Then power down the system before replacing a fan.
Removing the power cord is also recommended as a safety precaution.
