Warning for SPARCserver 1000/1000E and SPARCcenter 2000/2000E Systems

Caution -

If you are installing the Sun Quad FastEthernet SBus adapter in a SPARCserver 1000/1000E or a SPARCcenter 2000/2000E system, your system's OpenBoot PROM must be release 2.26 or later. Release 2.26 is required on the master system board.

If you have installed the Sun Quad FastEthernet SBus adapter into a SPARCserver 1000/1000E or a SPARCcenter 2000/2000E system and the system's OpenBoot PROM is not 2.26 or later, attempting to reboot the system with the reboot, sync sync halt, or init 0 commands will cause a system reset and display following error message:

OA>. TEST FAILED - System Reconfiguration .........
OA>Swap to SBI Interrupt Status register caused trap

Contact your local service provider to order an upgrade kit if your SPARCserver 1000/1000E or SPARCcenter 2000/2000E OpenBoot PROM release is earlier than 2.26.
