  • Page 15: Preinstallation Planning

    Preinstallation Planning This chapter covers: • SCSI termination • SCSI cabling • SCSI drive preparation • Limitations on mixing Narrow and Wide SCSI drives Mylex Disk Array Controllers are designed to work in a variety of SCSI RAID application environments. Certain configuration steps need to be performed prior to installing the controller into a RAID environment.

  • Page 16: Scsi Termination

    SCSI Termination SCSI Termination The DAC960PG and DAC960PJ are equipped with automatic SCSI termination circuitry. If the controller is at the end of a SCSI bus, it automatically enables on-board termination. If all the SCSI devices on a channel are connected either to an internal connector of a channel, or to an external connector of a channel, the end of the SCSI bus farthest from the controller must have a terminator installed.
  • Page 17 Preinstallation Planning Figure 2-1. DAC960 Controller Termination Examples ☛ Note For this discussion, assume that the illustrated internal and external connectors are both on the same channel. It is better to terminate the ends of the SCSI bus itself than it is to terminate the end devices on the bus. This allows hot swap devices to be added or removed from the SCSI bus without affecting termination.

  • Page 18: Scsi Cabling

    SCSI Cabling SCSI Cabling Each Ultra SCSI channel supports up to 15 drives. The total allowable SCSI bus lengths will be limited to the single-ended bus lengths shown in Table 2-1. Table 2-1. Supported SCSI Formats and Bus Lengths Bus Speed, SCSI Drive Type* Max.(MB/Sec) SCSI-1...

  • Page 19: Scsi Drive Preparation

    SCSI Drive Preparation Prepare the drives for installation as follows: • Remove any terminators attached to the drive or set any drive termination jumpers to the disabled position. • Set the SCSI addresses on the drives. ☛ Note Each drive on a channel must have a unique ID chosen from 0 through 6 or 8 through 15.

  • Page 24: Safety Considerations

    Safety Considerations Safety Considerations Be sure to observe the following precautions before beginning the controller installation procedure: Caution Anti-static handling procedures are required. Leave the controller in its anti-static bag until it is time to plug the controller into the PCI slot. The use of a grounded wrist strap and other ESD protective measures are highly recommended.

  • Page 33: Battery Backup Unit Option

    Battery Backup Unit Option Product Description The Battery Backup Unit (BBU) option is an add-on module that protects the data in the RAID controller’s cache memory in the event of a power failure. The battery backup module monitors the write back cache on the DAC960PG and DAC960PJ and provides power to the cache if it contains data not yet written to the drives when power is lost.

  • Page 34: Installation

    Installation Installation Tools Needed The only tool needed for the installation is a small, flat-blade screwdriver. Procedure 1. If the DAC960PG or DAC960PJ is not already removed from the system, power down the system and then remove the DAC960PG or DAC960PJ.
  • Page 35 Figure A-2. Removing the Loopback Plug 3. Remove the protective pin cover and peel-off label from J1 on the BBU. 4. Leaving the 4 standoffs attached to the BBU, remove a nylon screw from the free end of each nylon standoff. Manual No.
  • Page 36 Installation Figure A-3. Installing the BBU 5. Install the BBU so that J1 on the BBU connects to J5 on the DAC960PG or DAC960PJ. Pin 1 on the BBU’s J1 must connect to hole 1 on the DAC960PG and DAC960PJ’s J5. The mounting holes on the BBU will line up with the mounting holes on the DAC960PG or DAC960PJ if the connectors are plugged in correctly.

  • Page 37: Operation

    Operation Battery Conditioning Prior to Use Battery conditioning is automatic. There are no manual procedures for battery conditioning or preconditioning to be performed by the user. Set-up – Enabling the Write-Back Cache The write-back cache is enabled by toggling the write-back/write-through mode switch.

  • Page 38: Maintenance

    Maintenance Maintenance No end user maintenance is required on the BBU. It is recommended, however, that the battery charge level be periodically checked using the Gas Gauge function in GAM (see the Global Array Manager Client Software Installation Guide and User Manual). Removing the Battery Backup Module The battery backup module will need to be removed for one of the following reasons:...

  • Page 39: Functional Description

    Functional Description General Operational Description Whenever the system is running, the BBU is standing by, monitoring the voltage level of VCC. In the event of a power failure, the VCC voltage level will begin to drop. When the BBU detects this voltage drop, it checks the status of the disk cache.
