CAUTION Unplugging a single power cable can power down the entire switch, depending on which power supply slots contain power supplies. Two power cords are provided to connect the switch chassis to the PDUs. PDU and country specific cables are ordered separately. The AC power switches light up green when on. Blower Assemblies The switch is cooled by three blower assemblies located on the blower assembly side of the chassis. The air enters through the vents on the blower assembly side of the chassis and exits from the vent in the top of the port side of the chassis. The chassis requires a minimum airflow of 350 cubic feet per minute. This requires a minimum of two blower assemblies operating at all times. The blower assemblies are hot-swappable. If more than one blower assembly must be removed at the same time, turn off the switch to prevent overheating. WARNING The HP StorageWorks Core Switch 2/64 requires a minimum of two functioning blower assemblies during operation. To ensure continuous adequate cooling, maintain three operating blower assemblies at all times except for the brief period when replacing a blower assembly. The HP StorageWorks Core Switch 2/64 16-port cards automatically shut down if the temperature range is exceeded. CAUTION Disassembling any part of the blower assembly voids the part warranty and regulatory certifications. There are no user-serviceable parts inside the blower assembly. To determine the status of a blower assembly: 1. Check the LED indicators on the blower assembly. 50 getting started and general reference guide
