1-K Power LED Connector

Jumper D31 is a three pin power LED header that can be used if you have a 3 pin Power LED. Otherwise refer to panel connector J16 for 2 pin LEDs. 3 pin LED’s can still be used on J16 where pin 13 would be for the Ground pin.

CMOS RTC

The Real Time Clock (RTC) circuit, which provides the date and time for the system is integrated into the Via Apollo Pro Plus 133AAGPset. 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).

Flash EEPROM

The Trinity 400 uses flash memory to store BIOS firmware. It can be updated as new versions of the BIOS become available. You can upgrade your BIOS easily using the flash utility (see page 60).

2. Mounting the Motherboard in the Chassis

Follow the instructions provided by the case manufacturer for proper installa- tion guidelines. TYAN recommends that you use only one screw to hold down the motherboard. The rest of the mounting holes should be used for the plastic standoffs. If your case does not have a hole for a standoff, simply cut off the bottom of the plastic standoff so that the flat portion rests on the metal. The adapter cards and the screws holding them down will keep your board flat. The fastening screw should not short any of the traces on the motherboard. Make

!certain that you do not overtighten the screw, as it will damage the mother- board and possibly break internal traces in the surrounding area. The hole you

important! should use is located at the top-center of the board where the adapter cards are fastened to the case.
