D.6.1 SPARCstation 1, 1+, 2, SPARCstation IPC, IPX, LX, and
SPARCclassic System Circuit Breakers
The SPARCstation 2, SPARCstation IPC, IPX, LX, and SPARCclassic systems do
not use conventional fuses. Instead, they use self-healing thermal devices
(which normally never need to be replaced). This type of circuit breaker is
turned off when it gets too hot. This condition is usually caused by a short. It
requires removal of the object that caused the short. After the short condition is
removed, the system needs a cool-off period.
Warning – Before performing this procedure, make sure the system power is
turned off. Failure to comply may result in physical injury.
Do the following in sequence:
1. If the short condition is outside the system unit, remove it.
2. Wait about ten minutes and reboot the system.
If the previous procedure does not solve the problem, a short condition may
exist inside the system unit. Do the following in sequence:
1. Remove the system unit cover.
Follow all the safety cautions and warnings.
2. Visually inspect and remove any foreign matter or metal pieces that might
have been introduced in the TurboGX/TurboGXplus installation process.
3. Close the system unit.
4. Wait for about 10 minutes and reboot the system.
If the problem still exists, contact Sun Microsystems at 1-800-USA-4SUN
(within the USA) or contact your Sun Sales Representative.
