  • Page 18: Overview

    About the CX700 Overview The CX700 is a highly available storage enclosure with redundant power and cooling. It is four U high (a U is a NEMA unit, each unit being 1.75 inches) and supports two storage processors (SPs). Each SP has four host I/O ports and four back-end disk ports.

  • Page 19: Cx700 Components And Features

    About the CX700 A CX700 can support a total of 240 disks in a single disk-array storage system. A four-loop configuration (with maximum performance and availability) supports as many as 60 disks per back-end (BE) port; a two-loop configuration can support 120 disks per back-end port. You can place the DAE2 enclosures in the same cabinet as the CX700 SPE, or in one or more separate cabinets.

  • Page 58: 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 59: 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.
