Getting Started

If an error occurs, access the Operator Control Panel to determine the cause and locate the failed component. For more information, see Operator Control Panel on page 40. The fans are identified on the rear door panel using a placard for “FAN 1” and “FAN 2.” For more information on changing a cooling fan, see Replacing the Cooling Fans on page 60.

Hot Swap Power Supplies

CAUTION: Power supplies must be replaced by qualified service personnel only.

Up to three 150 watt hot swap power supplies are incorporated as part of a fault-tolerant design (N+1 power system). Each power supply unit (PSU) has current share circuitry which balances the load between the installed power supplies. In the event of a power supply failure, the load is transferred to the remaining power supplies without interruption to the CR8e’s normal operation.

If a failure occurs, the Power Supply Status LED will illuminate amber and an alarm will sound. The user can identify the failed component by accessing the OCP and viewing the “Hardware Status.” The PSU “DC Good” LED will not be illuminated on the failed power supply. For more information, see Replacing a Power Supply on page 58.

Power Switch

The power switch is located inside the locking front door and controls AC power to all of the power supplies. This positioning of the switch deters unauthorized users from powering down the CR8e provided the door is locked. The switch is recessed to prevent inadvertent activation during service activities.

The switch is labeled with a “I” for the ON condition and “O” for the OFF condition and is illuminated when the power is on for easy identification. Depending on the orientation of the subsystem (i.e., in the rack configuration) the “I” label will appear as a “— ” and should be interpreted as the ON condition.

Door Lock

The front door has an integral lock that also serves as a door handle. In addition, the door lock provides security to deter unauthorized access to the disk drives and SAF-TE card. Two keys are provided with the system.

To unlock the door, insert the key and turn it in a counterclockwise direction. To lock the door, turn the key in a clockwise direction.
