9 Install Additional Mass Storage Devices This HP NetServer supports both hot-swap SCSI devices, installed in the hot-swap mass storage cage, and non-hot swap SCSI devices, installed in shelves 3 and 4 (located below the CD-ROM drive). Use only Ultra2 (LVD), SCA-2 connector hot-swap devices in the hot-swap mass storage cage. You can use any standard (non-Ultra2) wide, 68-pin single-ended SCSI device in non-hotswap shelves 3 and 4, such as a removable hard disk or a tape backup drive. Narrow (50-pin) SCSI devices are supported in the non-hot-swap shelves, but require a 68-to-50-pin cable adapter for connecting the data cable to the device. (One adapter is provided on the SCSI cable behind shelf 3.) Pin Engages Hole in Edge of Cage Locking Latch CAUTION Do not mix Ultra2 devices with other SCSI devices. Use only Ultra2 devices in the hot-swap mass-storage cages. Use only non-Ultra2 (wide or narrow) devices in the non-hot-swap shelves (shelves 3 and 4). SCSI Addressing Different form-factor hot-swap disk drive modules can be mixed and matched within the hot-swap mass storage cage. Because so many different configurations are possible, SCSI addresses assigned to the modules will be different depending on the particular configuration. See "Non-Hot-Swap SCSI Addressing," below, for addressing restrictions on non-hot-swap devices. Inserting a Hot-Swap Disk Drive Module 1. Open the drive by pressing in on the locking latch at the end of the drive ejector handle and pulling open the handle. 2. Choose a location in the hot-swap mass-storage cage and gently slide the drive into the cage. Stop when you feel resistance. 3. Verify that the locking pin behind the pivot end of the handle engages the hole in the chassis. (See figure, at right). 4. With even pressure, gently close the ejector handle until the locking latch clicks shut. Ejector Handle Removing a Hot-Swap Disk Drive Module 1. Let the drive spin down completely before removing it. 2. Press in on the locking latch at the end of the drive ejector handle and gently open the handle. 3. Slowly pull the drive out of the cage. CAUTION Do not operate this NetServer -- even for short periods -- without a tray, filler panel, or drive spacer in every hot-swap and non-hot-swap mass storage location. Otherwise, damage to components may result due to improper cooling airflow. Hot-Swap Module Configurations and SCSI Addresses Both half-height (1.6-inch) and low-profile (1-inch) form-factor devices may be installed in the hot-swap mass-storage cage. There are two different height hot-swap trays available to accommodate drives of different form factors. Six low-profile devices or four half-height devices, or combinations of these two devices may be installed in the hot-swap mass-storage cage. NOTE For maximum storage density and to avoid configuration problems, install hot-swap drives in consecutive locations only, beginning with the lowest location in the mass-storage cage. Because of the height difference between half-height and low-profile devices, some combinations of the two types of trays will require spacers to take up space between devices. The figure below shows the different combinations of hot-swap devices possible. SCSI addresses are assigned automatically depending on the location of a drive module within the mass storage cage. SCSI addresses listed here are for SCSI A only. Refer to the Low-Profile Disk Module or Filler Panel Key: 1 Disk Spacer Half-Height 0 Disk Module Numbers on the Modules Indicate Assigned SCSI Addresses 9 9 8 8 8 8 3 3 3 3 2 2 1 1 1 0 0 0 0 9 8 9 8 8 8 3 3 3 3 1 2 1 2 3 1 1 1 0 0 0 0 0 Non-Hot-Swap SCSI Addressing SCSI Addresses Each SCSI device must have a unique SCSI the Technical Reference Card, located in the pouch on the address. Devices connected to the SE connector inside of the NetServer cover, for the recommended SCSI (those located on the non-hot-swap shelves) and to addresses. the SCSI B connector (not used in the factory- configured models) share one SCSI bus. Therefore each device connected to either of these connectors must have a unique address (narrow devices may use addresses 0-6; wide devices may use addresses SCSI Termination The NetServer SCSI cable is terminated. Verify that no added devices are terminated. 0-15, except address 7). JUMPERS A0 A1 A2 A3 Jumper Settings The figure to the right is typical of a SCSI hard disk drive that may be used in this NetServer. Use this as a general reference for jumper locations and settings. Typically, jumpers A0, A1, A2, and A3 determine the SCSI address. Refer to the documentation that came with the SCSI device for the jumper location and settings.
