An asterisk (*) indicates the default value of each jumper. NOTE: For two-position jumpers (3-post), "RIGHT" is toward the bracket end of the board; "LEFT" is toward the memory sockets. JU1/2 System Flash ROM Operational Modes The Flash ROM has two programmable sections: the Boot Block for "flashing" in the BIOS and the Main Block for the executable BIOS and PnP parameters. Normally only the Main Block is updated when a new BIOS is flashed into the system. JU1 JU2 All Blocks Write Enabled Remove * Remove * Boot Block Write Protected Install Remove Block 2-16 Write Protected Remove Install JU5/7 SPEED LED - LAN 1/LAN 2 These jumpers are used in conjunction with the Link/Speed LEDs for LAN 1 (JU5) and LAN 2 (JU7). The LEDs are located on the SBC's LAN connectors. For further information, see the Ethernet LEDs and Connectors section below. Install to use the Link/Speed LED to indicate that the Ethernet interface has a valid link at either 1000-Mb/s or 100-Mb/s. Green = valid link at 1000-Mb/s * Orange = valid link at 100-Mb/s Remove to use the Link/Speed LED to indicate that the Ethernet interface has a valid link at either 100-Mb/s or 10-Mb/s. Orange = valid link at 100-Mb/s Green = valid link at 10-Mb/s Trenton Support Center – XPI Technical Information -- Jumpers, Connectors and Memory 1 TRENTON Technology Inc. 2350 Centennial Drive • Gainesville, Georgia 30504 Sales (800) 875-6031 • Phone (770) 287-3100 • Fax (770) 287-3150 JU6 Thermal Throttling LED If the processor core gets to a critical temperature, it slows itself down to half its normal speed. This jumper sets the way in which the LED displays in response to this self-limiting mode. Install for real-time activity. The LED lights only when the processor is operating in slow-power mode.* Remove for latched activity. The LED lights and stays on once the processor has gone into slow-power mode. JU8 Password Clear Install for one power-up cycle to reset the password to the default (null password). Remove for normal operation. * JU12 CMOS Clear Install on the LEFT to clear. Install on the RIGHT to operate. * NOTE: The CMOS Clear jumper works on power-up. To clear the CMOS, power down the system, install the jumper, then turn the power back on. CMOS is cleared during the POST routines. Wait for AMIBIOS to display a "CMOS Settings Wrong" message; then power down the system again and remove the jumper before the next power-up. ETHERNET LEDS AND CONNECTORS Each Ethernet interface has two LEDs for status indication and an RJ-45 network connector. LED/Connector Description Activity LED Orange LED which indicates network activity. This is the upper LED on the LAN connector. Off = Indicates there is no current network transmit or receive activity. On = Indicates network transmit or receive (flashing) activity. Link/Speed Bi-color (green/orange) LED which LED identifies the link status and connection speed. This is the lower LED on the LAN connector. Green = Indicates a valid link at either 1000-Mb/s or 10-Mb/s, depending on the setting of the associated Speed LED jumper (JU5 or JU7). Orange = Indicates a valid link at 100-Mb/s, regardless of the setting of the associated Speed LED jumper (JU5 or JU7). NOTE: For further information on the Speed LED jumpers, see the Configuration Jumpers section earlier in this chapter. RJ-45 Network RJ-45 Network Connector The RJ-45 network connector requires a Connector category 5 (CAT5) unshielded twisted-pair (UTP) 2-pair cable for a 100-Mb/s network connection or a category 3 (CAT3) or higher UTP 2-pair cable for a 10-Mb/s network connection. A category 5e (CAT5e) or higher UTP 2-pair cable is recommended for a 1000-Mb/s (Gigabit) network connection.

The System BIOS automatically detects memory type, size and speed. The SBC uses industry standard 72-bit wide gold finger PC1600 or PC2100 memory modules in two 184-pin sockets. NOTE: Memory modules must be installed in both sockets and must be the same size. All memory modules must have gold contacts. The SBC supports DIMMs which are PC1600/PC2100 compliant and have the following features: • 184-pin with gold-plated contacts • ECC (72-bit) memory • Registered configuration The following DIMM sizes are supported: DIMM Size DIMM Type ECC 64 MB Registered 8M x 72 128 MB Registered 16M x 72 256 MB Registered 32M x 72 512 MB Registered 64M x 72 1 GB Registered 128M x 72 2 GB Registered 256M x 72 Trenton Support Center – XPI Technical Information -- Jumpers, Connectors and Memory 8
