1-26 System Overview
Degradation
If a CPU or a memory DIMM board error was detected during execution of
POST (Power On Self-Test) after system power is turned on, the degradation
function isolates the failed CPU or memory DIMM board and continues
operation. You should replace the failed device as soon as possible.
This function is enabled only when the following system requirements are met:
„
Two or more CPUs are installed.
„
Two CPU backboards (Tertiary cache) are installed
„
Eight memory DIMM boards are installed.
A CPU or memory DIMM board error may be viewed on the screen while
POST is running or by entering BIOS Setup." It may also be viewed when the
ESMPRO program is installed and operating.
AC Linkage Mode
When the power cord of the server is connected to an uninterruptible power
supply (UPS) unit, the server supports the power linkage function. This function
controls the server power from the UPS. This mode can be switched by using
the control switch on the rear panel.
Sleep Mode
The SLEEP mode switch on the front of the server is used for saving power.
If the SLEEP mode switch is pressed, then the server enters into the sleep state
(the Drive Bay Power lamp and the Power lamp will blink simultaneously). In
the power saving mode, the memory data and the states of the jobs are kept
unchanged. In addition, the server in the power saving mode can accept accesses
to hard disks from other machines on the network and perform other network
jobs.
Sleep mode requires an operating system that supports its function.
Note: Windows NT 4.0 does not support the Sleep mode
function.
