Hard Drive Carrier Indicators
Each hard drive carrier has two LED indicators: an activity indicator and a status indicator. In
RAID configurations, the status indicator lights to indicate the status of the drive. In non-RAID
configurations, the status indicator remains off. See the table below for details.
LED Color State
Activity LED Blue Solid On
Blue Blinking
Status LED Red Solid On
Red Blinking at 1 Hz
Red Blinking with two blinks and
one stop at 1 Hz
Red On for five seconds, then off
Red Blinking at 4 Hz
Green Solid On
Amber Blinking at 1 Hz
System Cooling
Four 4-cm counter-rotating fans provide the cooling for the system. These fans circulate air
through the chassis as a means of lowering the chassis internal temperature. The SC827HQ+
system fans are hot-swappable. There is no need to power down the system when replacing
fans and new tools are required for installation.
It is very important that the chassis top cover is installed for the cooling air to circulate properly
through the chassis and cool the components.
Optional Fan Configurations
The SC827HQ+ model chassis is designed so that the default configuration of the system
is for each serverboard to control two fans (Figure 6-4). The fans are hot-swappable. Each
serverboard node in the chassis is connected to the backplane through the adapter card,
mounted in the serverboard drawer. In the event that one of the serverboard drawers is
removed, then the remaining serverboard will operate both fans.
Fan Configurations Options
SC827HQ+ Hot-Swappable Default Configuration
Fan A connected to backplane, backplane connected to Node A by
adapter card
Fan B connected to backplane, backplane connected to Node B by
adapter card
Fan C connected to backplane, backplane connected to Node C by
adapter card
Fan D connected to backplane, backplane connected to Node D by
adapter card

Installing Fans
Fan speed is controlled by system temperature via IPMI. If a fan fails, the remaining fans
will ramp up to full speed. Replace any failed fan at your earliest convenience with the same
type and model (the system can continue to run with a failed fan).
Changing a System Fan
1. If necessary, open the chassis while the power is running to determine which fan has
failed. (Never run the server for an extended period of time with the chassis cover
open.)
2. Remove the failed fan's power cord from the backplane.
3. Lift the fan housing up and out of the chassis.
4. Push the fan up from the bottom and out of the top of the housing.
5. Place the replacement fan into the vacant space in the housing while making sure the
arrows on the top of the fan (indicating air direction) point in the same direction as the
arrows on the other fans.
6. Put the fan back into the chassis and reconnect the cable.
