Before the computer is switched off or a hard reset is carried out, the ICP Controller first has

to write the current contents of its cache RAM back to the hard disk(s) (flush). The computer

may only be switched off or reset after all hard disk accesses have been completed. If this is

not observed there is a high risk of data corruption and data loss ! A good indication for hard

disk activity is the front HDD-LED of your computer system (presuming it is connected with

the corresponding pin grid header of the GDT PCB). In addition, all GDT drivers (i.e. for all

supported operating systems) are designed to perform a cache flush when a regular system

shutdown is initiated (e.g., Under NetWare: Down and Exit; Under DOS: CTRL-ALT-DEL; Un-

der UNIX: Shutdown). They will show a message similar to the following "Flushing Controller

Cache". As long as this message is displayed you must not switch off or reset your PCI com-

puter. For Windows 95, Windows NT and OS/2 you may switch off or reset the computer as

soon as the operating system message is displayed, which indicates that it is safe, to turn

off the computer now.

The RISC CPU of the ICP Controller is equipped with a cooler. The cooler keeps the oper-

ating temperature of the CPU within the specified limits. The air intake is on the top of the

fan. The air flows through the fins of the heat sink and leaves it on the left and right side. In

addition, it is necessary that the whole ICP Controller is positioned in a constant airflow.

Normally, good server enclosures have extra fans for the motherboard expansion slot area.

In case of over temperature, the ICP Controller sends a message to the operator.

The cooler on your ICP Controller may look different from the one on pages of this manual.

Depending on the type of i960 Rx CPU installed on the ICP Controller, with some models, the

cooler is completely missing. This is intended !

All variants fully comply to the specifications laid down in this User's Manual.
