9 Install Additional Mass Storage Devices Preinstalled Devices ! A flexible disk drive is preinstalled in Shelf 1. ! An IDE CD-ROM drive is preinstalled in Shelf 2. ! Some models have a SCSI hard disk drive preinstalled in Shelf 3. ! Some models have a hot swap subsystem that can support up to three hot swap drive modules. NOTE For certain mass storage configurations you may need additional cables or adapters. See Order Assistant and Information Assistant for configuration information and part numbers. Non-Hot Swap SCSI Drives HP SCSI tape drives and hard disk drives for the HP NetServer LC II come preinstalled in mass storage trays. 1. Set the SCSI address: Set the jumpers on the drive to an unused SCSI address. Refer to the drive's installation guide, the Technical Reference Label inside the HP NetServer top cover, and the SCSI Addressing Examples below for instructions. Verify that the drive's SCSI termination enable jumper (TE in the example below) is set to OFF. 2. Install the drive: Remove the cover from an empty mass storage shelf, and store it for future use. Install the drive in its tray in the shelf opening. 3. Connect the cables: Connect SCSI and power cables to the drive. Refer to the Technical Reference label for cabling examples. For narrow (50-pin) SCSI tape drives, use the wide-to-narrow SCSI cable adapter with the white body on the the HP NetServer's SCSI cable. Do not use that adapter for wide (68-pin) SCSI drives. Hot Swap Disk Drive Modules Hot swap disk drive modules can only be installed in hot swap subsystems. The three trays in the optional HP NetServer LC II hot swap subsystem have SCSI addresses pre-set to 1, 0, and 3 from left to right, as viewed from the front of the HP NetServer. If you have a non-hot swap SCSI device with SCSI address 0, 1, or 3, change it or the SCSI addresses on the hot swap subsystem so that they do not conflict. To change the hot swap SCSI addresses, move the switches on the rear of the hot swap subsystem, as shown in the SCSI Addressing Examples below. To remove the locking bar: Insert the key (provided in the key bag on the rear of the HP NetServer) into the lock on the locking bar (shown below). Press in on the lock, and then unlock it by turning the key clockwise. Slide the locking bar to the left, and then lift it straight up. To remove a module: If a shipping plug (shown in the detail below) secures the locking lever, remove it. Depress the locking tab atop the locking lever, lift the locking lever completely up, and remove the module. To install a module: If a shipping plug (shown in the detail below) secures the locking lever, remove it. Lift the locking lever up completely, insert the module into the hot swap tray in the hot swap subsystem, and depress the locking lever. To replace the locking bar: Align the tabs on the locking bar (shown below) with the slots in the trim bezel. Insert the locking bar, and then slide it to the right. Insert the key into the lock, and turn it counterclockwise to lock the locking bar. CAUTION Depress the locking lever carefully to avoid breaking it. If it is difficult to depress, the module is in too far or is not seated properly. Lift the locking lever completely up, and reinsert the module.

This address dictates the SCSI device's boot priority and is set by jumpers located on the device, usually on the underside. Switches on the back of the hot swap subsystem set its SCSI addresses, as shown at near right. Jumper Settings The table to the far right shows typical jumper settings for wide (68-pin) SCSI devices. Jumpers A0, A1, A2, and A3 determine the SCSI address. Set the SCSI termination enable jumper (TE) to OFF, as shown in the table. Refer to the SCSI device documentation for the recommended jumper settings. Refer to the Technical Reference Label inside the top cover and to Information Assistant for the recommended SCSI addresses. SCSI Termination The HP NetServer SCSI cable is terminated, either by a terminator on the cable itself, or by the hot swap subsystem. Verify that jumper TE is set to OFF. Verify that no added SCSI devices are terminated.
