2. Remove options from system.
3. System can continue to operate without redundancy protection if
steps1 and 2 are not followed.

under nominal value; value for xcan be +12,
-12, or +5)
1. Check connections to the power subsystem.
2. Power supply.
3. Power cage assembly,if installed.

max value (level-critical; system drawing
too much current on voltage xbus)
vSee “Power checkout” on page 22.

(level-critical; system shutoff due to x
supply over voltage)
1. Check the power-supply connectors.
2. Power supply.
3. Power cage assembly,if installed.
