Cooling Subsystem

CAUTION

The chassis top cover must be installed for proper system cooling. Cooling components must be hot-

swapped within two minutes. This time period applies only to the time that the cooling component

is physically removed, not from the time of failure.

The cooling subsystem consists of hot-swap, redundant (2+2) fans. In the event of a cooling component

failure, system cooling is maintained and the system continues to operate while the component is

being hot swapped. Each fan module has a single LED to indicate its status. The LED will be off when

both fans are operating normally. The LED will illuminate amber if one or both of the fans fails. Failed

fans can be hot-swapped from the front of the chassis.

For proper processor cooling, the processor duct must always be in place. Systems not fully-configured

with four processors and four Memory Boards should have the processor heat sink and Memory

Board fillers installed to maintain proper cooling.

Hot-swap PCI Slots

The five hot plug PCI slots have power and attention LEDs. The attention button is used to invoke a

hot-plug sequence to remove or add an adapter without having to use the software interface. They

are identified by the green arrow on the PCI divider label. The status of the LEDs is shown in Table

8 and Table 9.
