8 p5-550 Technical Overview and Introduction 60/150 GB 16-bit 8 mm Internal Tape Drive, FC 6134 36/72 GB 4 mm Internal Tape Drive, FC 62581.3.4 USB diskette driveFor today’s administration tasks, an internal diskette drive is not state-of-the-art. In somesituations, the external USB 1.44 MB diskette drive for p5-550 systems (FC 2591) is helpful.This super-slim-line and lightweight USB V2 attached diskette drive takes its powerrequirements from the USB port. A USB cable is provided. The drive can be attached to theintegrated USB ports, or to a USB adapter (FC 2738). A maximum of one USB diskette driveis supported per integrated controller/adapter. The same controller can share a USB mouseand keyboard.1.3.5 I/O drawersThe p5-550 has five internal PCI-X slots, where four of them are long slots and one is a shortslot. If more PCI-X slots are needed, especially well-suited to extend the number of LPARsand Micro-Partitions, up to eight Model 7311 Model D20 I/O drawers can be attached to therack-mount p5-550 system. Up to four Model D20 drawers can be connected to the two RIO-2ports on the rear of the system that are provided in a minimum configuration. An additionalfour Model D20s can be connected by ordering the Remote I/O expansion card (FC 1806). Itprovides two RIO-2 ports located on a interposer card that occupies the short PCI-X slot.7311 Model D20 I/O drawerThe 7311 Model D20 I/O drawer is a 4U full-size drawer, which must be mounted in a rack. Itfeatures seven hot-pluggable PCI-X slots and optionally up to 12 hot-swappable disksarranged in two 6-packs. Redundant, concurrently maintainable power and cooling is anoptional feature (FC 6268). The 7311 Model D20 I/O drawer offers a modular growth path forthe p5-550 system with increasing I/O requirements. When a p5-550 is fully configured witheight attached 7311 Model D20 drawers, the combined system supports up to 61 PCI-Xadapters (in a full configuration, Remote I/O expansion cards are required) and104 hot-swappable SCSI disks.PCI-X and PCI cards are inserted from the top of the I/O drawer down into the slot. Theinstalled adapters are protected by plastic separators, designed to prevent grounding anddamage when adding or removing adapters.The drawer has the following attributes: 4U rack-mount enclosure assembly Seven PCI-X slots 3.3 volt, keyed, 133 MHz hot-pluggable Two 6-pack hot-swappable SCSI devices Optional redundant hot-plug power Two RIO-2 ports and two SPCN ports7311 Model D20 I/O drawer physical packageThe I/O drawer has the following physical characteristics: Width: 482 mm (19.0 inches)Note: The 7311 Model D20 I/O drawer initial order, or an existing 7311 Model D20 I/Odrawer that is migrated from another pSeries system, must have the RIO-2 ports available(FC 6417).
