System Overview 1-25
System Functions
The following subsections describe select system functions.
Hot Swapping
Hot swapping allows a device to be replaced, such as a hard disk drive while its power
is on, as listed below.
!
Disk array system:
Any failed hard disk drive can be replaced while the system is running.
!
Hot swap fans:
Any one of the two system fan modules (three fans per module) can be replaced
while the system power is on.
!
Power redundant system:
When three power supplies are installed on the four processor system a failed power
supply can be replaced by hot swapping.
Hot Plug PCI
Hot Plug PCI bus slots are located under the Hot Plug PCI Bay door of the server (see
Figure 1-9). This PCI bus allows devices to be installed or removed while the server is
powered on (if the operating system supports the Hot Plug PCI function.)
Note:
Windows NT 4.0 does not support the Hot Plug PCI
function.
Fans
In addition to the power supply fans, the server has six system fans contained in two fan
modules (three fans per module) cabled to the system board. The six fans (front and
rear) are hot swappable and redundant in configuration. If one fan fails, its associated
fan changes to high speed operation. For hot-swap fan numbering see Figure 1-10.
For fan module POST error codes and system event log (SEL) information see Table
1-6.
