8 Install Additional Mass Storage Devices 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 Devices NOTE HP SCSI tape drives and hard disk drives for the HP NetServer LC 3 come in their own mass storage trays. HP Hard Disk Pack 1. Set the SCSI address: Set the jumpers on the drive to an unused SCSI address. Refer to the drive's installation guide 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 the 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. HP Tape Drive SCSI Addressing Examples SCSI Addresses Hot Swap Subsystem Each SCSI device must have a unique SCSI address (ID). 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. Default SCSI Addresses 1, 0, 3: 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 Information Assistant for the recommended SCSI addresses. Alternate SCSI Addresses: 1, 2, 3 9, 10, 9, 8, 11 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.

The three trays in the HP NetServer LC 3 hot swap subsystem have SCSI addresses preset 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 change 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 above. Installing and Removing the Modules 1. 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. 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. 2. Remove a module: If a shipping plug (see illustration) secures the locking lever, remove it. Depress the locking tab on the locking lever, lift the locking lever completely up, and remove the module. 3. Install a module: Remove the trim bezel from the front of the server. If a shipping plug secures the locking lever, remove it. Lift the locking lever up completely, insert the module into the hot swap tray in the front of the server, and depress the locking lever. Shipping Plug Locking Tab Locking Lever Trim Bezel Trim Bezel Hot-Swap Module Hot-Swap Module Lock Locking Bar Slots 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. 4. Replace the locking bar: Align the tabs on the locking bar (see illustration) 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 counter-clockwise to lock the locking bar.
