Chapter 4 Installing Mass Storage Devices Duplex Board Preinstalled A small number of systems have a duplex board preinstalled. The duplex board supports dual-bus mass storage configurations. Duplex hot-swap drive configurations and SCSI IDs are later in this chapter. Upgrade If you are installing the duplex board, refer to the HP NetServer Duplex Kit Installation Guide that came with the Duplex Board Accessory Kit for other information. Mass Storage Guidelines Read this section prior to installing mass storage drives for a successful installation. Selecting SCSI Devices Hot-Swap Hot-swap mass storage comprises either a low profile (1-inch) or half-height (1.6-inch) drive in a tray. This is called a module. For the hot-swap shelves use HP Ultra-2 (LVD) or Ultra-3 SCSI 3.5-inch hard disk drives. HP hot-swap drives are set for LVD SCSI operation and without device ID or termination. Do not change these settings. NOTE A half-height drive takes most of two slots. You must use a drive spacer to close up the remaining space. Non-Hot-Swap For the non-hot swap shelves, use 3.5-inch or 5.25-inch single-ended (SE) SCSI devices. This bay supports either two half-height or three low-profile devices. You can order HP mounting kits for removable media devices or trays for 3.5-inch hard disk drives (both low-profile and half-height). You may use narrow/wide SCSI adapters on these devices. 40
