System components AVA-400, AVA-800 Fan modules and their LEDs
The following are available system FRUs:
Fan modules: Hot-swappable
Power supplies: Hot-swappable
Controller module: Not hot-swappable
Each controller module has internal FRUs which are not hot-swappable. Use the reload halt command to ensure a
clean shutdown, and then power off the controller to replace these FRUs.
The following are available internal FRUs:
Boot media device
RAID controller assemblies
Real-Time Clock (RTC) coin battery
System DIMM
Slot numbering and associated components
An AltaVault controller controls three fan modules. Controller A controls the fans in slots A1 through A3. If a
controller is removed from the chassis, the fans in all three associated fan modules stop spinning.
Three fan modules are shipped preinstalled on the front of the chassis in the slots labeled A1 through A3. The chassis
has six slots on the chassis front and four slots on the chassis rear. The bottom row of fan modules are replaced with a
blank because these fan modules are not required.
To locate chassis components in an AltaVault system
1. You must remove the front bezel to see the slots that contain the fan modules in the chassis.
2. Use the information that follows to locate the slots and the components that they accept:
Fan modules and their LEDs
If the controller does not detect the presence of the associated fan module, the system fails to boot. Each fan module
is a hot-swappable field-replaceable unit (FRU) that contains two fans.
