The setup of the configuration jumpers on the
SBC is described below. * indicates the default value of each jumper.
For two-position jumpers (3-post), "TOP" is toward
the memory sockets; "BOTTOM" is toward the edge fingers.
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.
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 10Mb/s.
Green = valid link at 100-Mb/s
Orange = valid link at 10-Mb/s
Install for one power-up cycle to reset the password
to the default (null password).
Remove for normal operation. *
|
This jumper may be used to enable or disable
on-board active termination for the Ultra160 SCSI interface.
Install on the TOP to enable active termination *
Install on the BOTTOM to allow the AIC-7892 to control termination.
Remove to disable active termination.
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

Install on the TOP to operate.*
Install on the BOTTOM to clear.
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. Wait for at least two seconds and turn the power off. Then
remove the jumper and turn the power on. When AMIBIOS displays the
"CMOS Settings Wrong" message, press F1 to go to the BIOS Setup
Utility, where you may reenter your desired BIOS settings, load
optimal defaults or load failsafe defaults.

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 (i.e.,toward the
memory sockets). |
| Off |
Indicates there is no current network transmit
or receive activity. |
| On (flashing) |
Indicates network transmit or receive activity. |
| Link/Speed LED |
Bi-color (green/orange) LED which identifies
the link status and connection speed. This is the lower LED
on the LAN connector (i.e., toward the edge connectors). |
| 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 Jumpers section. |
|
| LED/Connector |
Description |
| RJ-45 Network |
The RJ-45 network connector requires a
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. |
|
|
Pin 1 on the connectors is indicated by the square
pad
on the PCB.

The
Double Data Rate (DDR) memory interface supports up to 2GB of memory
and can operate as either a single-channel (64-bit) or dual-channel
(128-bit) DDR interface. Each of the channels terminates in a dual
in-line memory module (DIMM) socket. Installing two identical DIMMs
doubles the interface bandwidth. The System BIOS automatically detects
memory type, size and speed.
The SBC uses industry standard 72-bit wide ECC
or 64-bit wide non-ECC gold finger PC2100, PC2700 or PC3200 memory
modules in two 184-pin sockets.
Memory modules
can be installed in one or both DIMM sockets. If two modules of
different speeds are used, the DIMMs will operate in dual-channel
mode at the speed of the slowest DIMM. If the modules are different
sizes, they will operate in single-channel mode. Registered DIMMs
are not supported. All memory modules must have gold contacts.
The SBC supports DIMMs which are PC2100/PC2700/PC3200
compliant and have the following features:
- 184-pin with gold-plated contacts
- ECC (72-bit) or non-ECC (64-bit) DDR memory
- Unbuffered configuration
The following DIMM sizes are supported:
