Board Installation
1-O. SCSI LED (J22)
This is the SCSI LED connector.
1-P. LAN LED (J45)
This is the LAN LED connector
1-Q. AUX Audio Connector (J44)
This connector is for plugging external audio
devices such as add on cards and other output
devices.
1-R. Server Management Connector (JP6)
The EXTSMI (External System Management Interface), connector JP6, is used
by some plug-in cards. Certain applications associated with these plug-in
cards use the interface for hardware control and queries.
Soft Power Connector
The Soft Power Connector is part of jumper block J9 (pins 6-8). The Tomcat
i810ef uses the chipset for power management, including turning on and off
the system. If the Power Button Function option in the BIOS Power Manage-
ment Menu is set to On/Off (which is the default), pressing the power button
once after the BIOS has booted up will turn the system on and off. If the
Power Button Function option is set to Suspend, pressing the power button
once will wake the system or send it to Suspend mode. In this case, you
cannot turn the system off unless you shut down through the Windows
operating system or you hold the power button down for four seconds.
Hardware Reset Switch Connector Installation
The Reset switch on your cases display panel provides you with the Hard-
ware Reset function, which is the same as power on/off. The system will do a
cold start after the Reset button is pushed.
CMOS RTC
The Real Time Clock (RTC) circuit, which provides the date and time for the
system is integrated into the 810e chipset. If the external battery for the RTC is
low, it will prevent your system from POSTing, and you will not get a display.
Normally the life span of an external battery is 2 years. If yours is running low,
you will need to replace it with a new 3V lithium battery (Sony CR2032).
