6.6 SCSI ID Source Selection
There are two sources for the SCSI ID. To use the switch to select the
SCSI ID, option jumper 2 (SW1-8) should be set to the OFF position. To
use the ID selection pins on the main interface connector, set SW1-8 to the
ON (default) position.
6.7 Other Jumper Definitions
The option 1 jumper at SW1-7 is used during initial testing at the factory
and should NOT be set to the ON position during normal operation.
6.8 Memory Size
Memory size is determined when the SC2500 is built and preformatted at
the factory. With some SCSI adapter cards the memory size is displayed
when the BIOS message is returned at power up. If that memory size
changes, contact Memtech factory repair. Memory capacity can only be
upgraded at the factory.
7. TROUBLE SHOOTING GUIDE
The following is a list of possible error indicators or messages, what they
indicate, and possible solutions to the source problem. If no solution is found,
contact the factory for further assistance.
7.1 Error Blink Codes -
If the LED issues a repeating blink code (accompanied by the drive not
responding to SCSI commands), this indicates a hard error condition as listed
in the table below. Contact the Memtech factory for repair service.
Number of Blinks

2
ROM Firmware Checksum error
3 ASIC

4

5

7 Flash/Data

7.2 Warning Blink Codes –
The LED is also used to indicate a number of warning conditions. If a
warning condition is encountered, the LED will issue the number of blinks
indicated below a single time, then continue the normal power-up
procedure. Please note that the warning condition is also entered after
each SCSI reset, so the blink code may be issued several times during
power-up at irregular intervals. Again, contact the Memtech factory for
service or repair.
