Performing an Emergency Shutdown
Performing an Emergency Shutdown
Attention:
Emergency situations might include: fire, flood, extreme
weather conditions, or other hazardous circumstances. If a power
outage or emergency situation occurs, always turn off all power
switches on all computing equipment. This will help safeguard
your equipment from potential damage due to electrical surges
when power is restored. If the expansion unit loses power
unexpectedly, it might be due to a hardware failure in the power
system or midplane (see Table 2 on page 60).
Use this procedure to shut down during an emergency.
1. If you have time, stop all activity and check the LEDs (front and
back). Make note of any fault LEDs that may be lit so you can
correct the problem when you turn on the power again.
2. Turn off both power supply switches; then, unplug both power
cords from the expansion unit.
