SC835 Chassis Manual Installing the Air Shroud, Rear Fan, and Checking Air Flow Figure 5-8: Installing the Air Shroud Air shrouds concentrate airflow to maximize fan efficiency. The SC835 chassis air shroud does not require screws to set it up. Note that the rear fans must be removed prior to installing the air shroud.
Chapter 5: Chassis Setup Chassis Maintenance System Fans Five heavy-duty fans provide cooling for the chassis. These fans circulate air through the chassis as a means of lowering the chassis' internal temperature. The SC835 chassis includes three front fans and two rear fans. SC835 chassis fans are fully hot-swappable.
SC835 Chassis Manual Rear System Fans The SC835 chassis includes three front fans and two rear fans. The front fans are pre-installed. The rear fans must be installed after motherboard and air shroud setup. Figure 5-10: Installing the Rear Fan Installing the Rear System Fans Installing a the Rear System Fans Confirm that the air shroud is correctly placed.
Chapter 5: Chassis Setup Checking the Server's Air Flow Checking the Air Flow Make sure there are no objects to obstruct airflow in and out of the server. If necessary, route the cables through the cable rack. Do not operate the chassis without drives or drive trays in the drive bays. Use only recommended server parts.
SC835 Chassis Manual Power Supply The power supply for the SC835 chassis is redundant and hot-swappable, meaning that the power supply can be changed without powering down the system. Replacing the Power Supply Replacing the Power Supply The SC835 chassis includes a redundant power supply (at least two power modules).
