Chapter 6: Advanced Chassis Setup
6-3 System Fans
Each serverboard has its own set of three

System Fan Failure
If a fan fails, the remaining fans will ramp up to full speed and the 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 deter- mine 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.
6-4 Drive Bay Installation/Removal
Accessing the Drive Bays
SATA Drives: Because of their hotswap capability, you do not need to access the inside of the chassis or power down the system to install or replace SATA drives. Proceed to the next step for instructions. Note: The operating system you use must have RAID support to enable the

Use caution when working around the SATA backplane. Do not touch the backplane with any metal objects and make sure no cables touch the backplane. Also, regardless of how many SATA drives are installed, all four drive carriers must remain in the chassis to maintain proper airflow.
SATA Drive Installation
The SATA drives are mounted in drive carriers to simplify their installation and removal from the chassis. These carriers also help promote proper airflow for the system. For this reason, even empty carriers without drives installed must remain in the chassis.
Mounting a SATA Drive in a Carrier
1.Install the drive into the carrier with the printed circuit board side facing down so that the mounting holes align with those in the carrier.
2.Secure the drive to the carrier with four screws, as shown in Figure
