  • Page 17: Fan Unit

    This Technical Description describes fan units used in the VCO/4K system. The fan unit draws hot air from inside the VCO/4K and discharges it through the rear of the VCO/4K enclosure. The fan unit has an alarm indicator (LED) that illuminates when any of the four cooling fans has failed.

  • Page 18: Component Description

    3.0 COMPONENT DESCRIPTION The fan unit is in the top 2U of the VCO/4K. When the system is powered on, the fan unit draws hot air from inside the VCO/4K and discharges it through the rear of the system’s enclosure.
  • Page 19 Note that the rear of the fan unit refers to the part of the unit which is not visible when the unit is installed in the VCO/4K. When installed, the rear of the fan unit is facing the front of the system’s enclosure.

  • Page 21: The Fan Controller Cards

    The fan unit contains three controller cards located between the fans and the front panel, inside the tray. Power is supplied to the fan unit from the VCO/4K’s power backplane through the plug located on the rear right side of the unit. Power goes onto the fan control cards through the J5 connectors.

  • Page 22: Removal/Replacement Procedures

    REMOVAL/REPLACEMENT PROCEDURES 5.0 REMOVAL/REPLACEMENT PROCEDURES Only replace your fan unit in the event of a fan or fan-control card failure. The VCO/4K system can operate without severe damage if up to two fans fail. However, replace your fan unit as soon as possible.

  • Page 23: Replacement Procedures

    1. Unpack the replacement fan unit. Be sure all packing materials have been removed. 2. Lift the fan unit into position so the top of the unit is flush with the top of the VCO/4K enclosure, and guide about half-way into the system enclosure. If the unit cannot be guided or lifted into the enclosure, make certain that the top of the unit has been correctly positioned.

  • Page 24: Power Failure

    Remove the fan unit and check that the power plug on the back, left side of the fan unit is plugged in. If the fan unit still does not operate, contact and report your findings to Cisco Systems Technical Support and request further assistance.

  • Page 41: Storage/Control I/O Module

    The Storage/Control I/O Module performs two functions: to connect outside interfaces to the system controller and to house the hard disk drive. It plugs into the back of the VCO/4K system and provides the I/O interfaces for system peripheral devices and host communication links using four serial ports, one Ethernet port, one printer port and one SCSI connector.

  • Page 42: Description

    All internal connectors are mounted on the board itself for easy access to system internals (for example, SCSI and Ethernet). The VCO/4K system hard drive is mounted on the upper portion of the I/O Module. The board is built to accommodate a 3.5 inch hard drive. Physical mounting points are provided for the hard drive as well as a 50-pin SCSI interface to the system controller.
  • Page 43 Description Power is supplied to the Storage/Control I/O Module via the midplane from the combined controller card. The hard drive LED signal is brought to the system controller board via the midplane and brought out to the front panel to show hard drive activity. It is located on the combined controller in the front of the VCO.
