one without any interruption in Fibre Channel service. However, if external power is completely lost, all Fibre Channel ports will go into a standby mode after a short user- defined timeout period because the system will power off.

Warning:

Do not remove both power supplies from the system at the same time. This will cause system failure since the internal batteries require that at least 1 power supply be present in the system at all times. If both supplies are physically removed from the chassis, possible data loss may occur.

The following buttons and indicators are on the power supply:

∙The top button provides a means to activate the power supplies (turn them on) after a user-initiated system shutdown. When a user initiates a shutdown of the system, the power supplies are typically still connected. Therefore, the system cannot use the presence or absence of AC to know whether to operate. In order for the power to come on after a user initiated shut down, the top button must be pressed on either of the power supplies. If power is restored after a power failure or a power cord is reinserted, the system will automatically power on.

∙Low Voltage indicator light. The top indicator light shows when the power supply is operating below the voltage necessary to power the entire system. Low voltage indications are a sign that the power supply needs to be monitored and possibly replaced.

∙Battery Operation indicator light. The bottom indicator light shows when the system is operating from battery power. The system should only operate from battery power when external AC power has failed.

Warning:

The power supply modules maintain high voltage levels during normal operation. To prevent the risk of electrical shock, remove the power cord and wait 15 seconds before removing a power supply module.
