Bull Cedoc Novascale R422, Installation And User Manual

Advanced Chassis Setup
6-3
6-3 System Fans
Each serverboard has its own set of three 4 cm high-performance fans (for a total of six in
the chassis) to provide the cooling for the NovaScale R422/R422-INF. Fan speed may be
controlled by a setting in BIOS ( see Chapter 7 ).
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 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.
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.
Use caution when working around the SATA backplane. Do not touch the
backplane with any metal objects and make sure no ribbon 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 air fl ow.
SATA Drive Installation
1. Mounting a SATA drive in a drive carrier
The SATA drives are mounted in drive carriers to simplify their installation and removal from
the chassis. These carriers also help promote proper air fl ow for the system. For this reason,
even empty carriers without drives installed must remain in the chassis. To add a new drive,
install it into the carrier with the printed circuit board side facing down so that the mounting
holes align with those in the carrier. Secure the drive to the carrier with four screws, as
shown in Figure 6-3.
!
NOTE
:
The operating system you use must have RAID support to enable the hot-swap
capability of the SATA drives.
