    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.

    SCSI bus termination will occur automatically. Power Cord Connector and Fuse The power cord connector supplies the AC power to the CR8e through a power cord connected to a conventional three-hole grounded outlet or power strip. A 250V 10 amp fuse is provided to protect the system from any electrical fault.

  • Page 19: Configuration Modules

    Configuration modules must be installed or replaced by qualified service personnel only. The CR8e’s SCSI bus design provides either of two bus configurations which is determined by the configuration module installed. The Dual-Bus module provides a split bus configuration where the enclosure’s top four drive slots and the lower four drive slots are on two independent SCSI buses.

  • Page 20: Controlling And Monitoring

    Operator Control Panel The Operator Control Panel (OCP) provides control and monitoring capabilities through an LCD panel located on the front door of the CR8e. The disk drives, power supplies, fans, and processor can be monitored for their status by using the menu drive OCP interface.

    LEDs Power-On LED The Power-On LED signifies that the CR8e system has power applied. Status Indicator LEDs There are three Status Indicator LEDs to assist the user in determining the current state of the CR8e subsystem. The following subsections describe each LED.

  • Page 22: Status Leds

    Getting Started Power Supply Status The Power Supply Status LED indicates the condition of the power supplies. The LED will illuminate steady green when all the power supplies are functioning normally and will change to amber if one of the power supplies should fail. The LED will also switch to amber if the power system is in a non-redundant state.

    The upper slot (furthest left slot) is not used. SAF-TE The CR8e is designed to be compliant with version 1.0 of the SAF-TE (SCSI Accessed Fault-Tolerant Enclosure) specification. Under this specification, the enclosure is implemented as an assignable SCSI target ID. This allows standardized alert detection and status reporting using the SCSI bus as the underlying transport mechanism.
  • Page 24 When used in conjunction with the AdminiStor Storage Management software, the CR8e can alert the user or LAN administrator of conditions requiring their attention. These alert notifications can be made via network broadcast or electronic pages, in addition to the LEDs and Operator Control Panel alerts found on the CR8e subsystem.

    Installation System Requirements The nStor CR8e disk subsystem is based on an open architecture design and can be connected to any host-based SCSI system. Refer to your adapter/controller and host system user’s manuals for information about the system requirements for the host system where the controller will be installed.

    Mount the subsystem into the rack enclosure before installing the disk drives. This will reduce the weight required to support during installation. Select an appropriate location in your rack cabinet for the CR8e. If you are installing multiple systems, review the cabling configuration section later in this chapter for your cable scheme to determine the optimum locations.

    Installation Component Installation CAUTION: Disk drives and printed circuit board components are sensitive to electrostatic discharge. To prevent operating failure or damage, observe the following: Establish a ground for yourself by using the wrist grounding strap, or by touching the metal chassis prior to handling or installing the drives or printed circuit board components.
  • Page 30 NOTE: Verify that the power switch on the CR8e is in the OFF position (O). Connect one end of the power cord to the power connector on the rear panel and the other end to a three-hole grounded outlet or power strip. A UPS is recommended.
  • Page 31 CAUTION: Power supply installation is to be performed by qualified service personnel only. There is no need to power off the CR8e or the computer system. The power supplies are hot swappable. Loosen the two screws on the Power Supply #3 cover plate using a flat-blade screwdriver and remove the cover plate.

  • Page 32: Cabling Configuration

    When calculating the total length of your cabling, the internal subsystem length of cables and printed circuit board traces (known as the internal cable length) must be subtracted from your total cable length. The CR8e internal cable length is 36 inches.
  • Page 33 Installation Because of the enhancements in the CR8e, its possible to extend beyond the limits set forth in the specification. However, a symptom from exceeding this cable limit is a SCSI bus lockup or “freeze.” If you experience a similar problem and are aware of a cabling limit issue, reducing the length of cabling and returning the total length to within the specified limit should resolve any problems.
