Diagnostics

Once the LAN adapter is installed and cabled, use the AUTOSET diagnostic program to

check the adapter installation.

Note that the AUTOSET diagnostic program test requires that the adapter be attached to a

properly-terminated network or to a BNC “T” connector that has two terminators

connected (if thin Ethernet is used). Once the cable is installed, use the AUTOSET

diagnostic program to check the network interconnection.

Select the Diagnostics option in the AUTOSET menu. The Initialization and Diagnostics

menu displays. The configuration options currently chosen are listed in parentheses. The

following displays while several options are checked:

Network Interface Controller (12-byte node address).......OK

Buffer Memory Check.......................................................OK

Check Cable Connection (Cable Connected)....................OK

Interrupt Assignment (5) ...................................................OK

Boot PROM Check (No Boot PROM)..............................OK

Press ESC to return to the previous menu. If Diagnostics reveals an error, return to

the Display/Change configuration menu and make the necessary changes. Run

Diagnostics again.

Error Messages

The AUTOSET software has several associated error messages that may display during

operation. These error messages are explained below.

• Out of memory error

This message displays only during development and should never display during

normal operation. If this message displays, contact RadiSys Technical Support.

•

No adapter at this address

This message displays when the address selected does not have an attached Ethernet

controller network adapter card. Check the hardware to make sure the Ethernet

controller is properly seated and functioning. If the message continues to display,

select another address such as 300h, 280h, etc. If an address change does not fix the

problem, the Ethernet controller should be replaced.

•

Error — multiple boot ROMs detected

This error has been automatically corrected

Please re-power the PC to enable the corrections

This message displays when more than one installed Ethernet controller adapter has

enabled a boot ROM. Only one network boot ROM should ever be installed in a PC.

To correct this, the adapter at the lowest address should remain enabled, and all other

adapters should be set for no boot ROM. After saving the changes in the software,

invoke a hardware reset—either push the reset button, or turn the system off, wait ten

seconds, then turn it back on.
