Each supply supports a fully configured SPE and shares load currents with the other supply. A FRU with power-related faults will not adversely affect the operation of any other FRU.

  • Page 29: Fan Module

    About the CX700 Fan Module The CX700 fan modules (Figure 1-12) cool the two storage processors. Separate, integrated fans cool the power supplies. There are three fan modules, each containing two fans that draw ambient room air through the front bezel. Each fan module connects directly to the midplane and is powered by the power supplies.

  • Page 30: Standby Power Supply (Sps)

    About the CX700 Standby Power Supply (SPS) Configurations that use ac source power require standby power supplies (SPS) to prevent data loss during a power failure.

Per evitare danni personali e/o all’apparecchiatura, non tentare di sollevare ed installare in un rack il contenitore senza un sollevatore meccanico e/o l’aiuto di un’altra persona. Debido a su considerable peso, la instalación del compartimento en el bastidor deben realizarla siempre dos personas.

  • Page 34: Cabling Requirements

    The standard 40U EMC cabinet includes two 240-volt ac power cables and independent power distribution units (PDUs) and power distribution panels (PDPs). To support all of the CX700 system’s high-availability features, you must connect each power outlet to a different circuit.

  • Page 35: Disk Requirements

    Setting Up and Starting a CX700 System unequalized 1-meter cables are adequate. A DAE does not support cables shorter than 1 meter or longer than 10 meters. DAE2P enclosures use cables with HSSDC2 connectors on at least one end. CX700 and DAE interconnections should maintain LCC consistency; that is, one set of FC loops should connect the CX700’s SP A and each DAE’s LCC A, and the other FC loops should connect the CX700’s SP B and each DAE’s LCC B.
  • Page 36 Setting Up and Starting a CX700 System The CX700 back end (BE) addresses each DAE using the FC-AL address (loop) ID and the DAE enclosure address (EA). You determine both the loop ID (sometimes called a bus ID) and the enclosure address during the hardware setup.

  • Page 54: Turning Off The Power - Dc Systems

    Setting Up and Starting a CX700 System CAUTION Never shut off the power supplies to shut down a CX700. Bypassing the SPS in that manner prevents the system from saving write cache data to the vault drives, and results in data loss. You lose access to data, and the storage processor log displays an error message similar to the following: Enclosure 0 Disk 5 0x90a (Can’t Assign - Cache Dirty) 0 0xafb40 0x14362c.
  • Page 55 Setting Up and Starting a CX700 System 2. If the server connected to the CX700 is running the UNIX® operating system, unmount file systems. 3.

  • Page 64: Avoiding Electrostatic Discharge (Esd) Damage

    Servicing a CX700 SPE Avoiding Electrostatic Discharge (ESD) Damage When you replace or install FRUs, you can inadvertently damage the sensitive electronic circuits in the equipment simply by touching them. Electrostatic charge that has accumulated on your body discharges through the circuits. If the air in the work area is very dry, running a humidifier in the work area will help decrease the risk of ESD damage.

  • Page 65: Emergency Procedures (Without An Esd Kit)

    Servicing a CX700 SPE Emergency Procedures (Without an ESD Kit) In an emergency when an ESD kit is not available, use the following procedures to reduce the possibility of an electrostatic discharge by ensuring that your body and the subassembly are at the same electrostatic potential.

  • Page 66: Precautions When Handling Optical Cables

    Servicing a CX700 SPE Store a FRU in the antistatic bag and specially designed shipping container in which you received it. Use that container if you need to return the FRU for repair. Maintain the location where you store FRUs within the limits specified in Appendix A.

  • Page 67: Replacing A Fan Module

    Servicing a CX700 SPE Replacing a Fan Module CAUTION Handle a fan module gently and use an ESD wristband. Do not remove a faulty fan module until you have a replacement available.
