  • Page 23 DIMM memory, accessory boards, and processors. Mass Storage The HP Server tc2100 comes standard with one IDE CD-ROM and one flexible disk drive with various possible configurations of SCSI or IDE hard disk drives, depending on the model (SCSI or IDE). The Server is limited to six internal mass storage devices (including a tape back up drive), four in the front shelves (or common trays) and two in the removable drive cage accessed from the side of the Server.
  • Page 24 Boot Priority The HP Server tc2100 is provided in two models, IDE or SCSI, and the model type affects the boot priority. The HP Server searches for bootable devices in a specific order, which is set up in the BIOS Utility.
  • Page 25 This section provides the configuration of the SCSI mass storage devices, if you have selected a SCSI version of the HP Server tc2100. The base SCSI model configuration has at least one SCSI hard drive (shelf 6) located in the removable drive cage and connected to the factory installed SCSI controller.
  • Page 26 Therefore, you can not connect external SCSI devices to the external connector when there are active internal SCSI devices connected to the internal SCSI connector. The HP Server tc2100 will support an HP NetRAID 1M controller board, separate from the SCSI controller board.
  • Page 27 External SCSI Connector The HP Server tc2100, SCSI model, has an external SCSI connector at the rear of the Server. This SCSI port cannot be used if there are active internal SCSI devices. The SCSI controller provided with the SCSI model of the Server is a single channel controller and cannot support internal and external SCSI devices at the same time.
