    Safety notices Safety notices may be printed throughout this guide: v DANGER notices call attention to a situation that is potentially lethal or extremely hazardous to people. v CAUTION notices call attention to a situation that is potentially hazardous to people because of some existing condition.
  • Page 8 DANGER When working on or around the system, observe the following precautions: Electrical voltage and current from power, telephone, and communication cables are hazardous. To avoid a shock hazard: v Connect power to this unit only with the provided power cord. Do not use the provided power cord for any other product.
  • Page 9 Observe the following precautions when working on or around your IT rack system: v Heavy equipment–personal injury or equipment damage might result if mishandled. v Always lower the leveling pads on the rack cabinet. v Always install stabilizer brackets on the rack cabinet. v To avoid hazardous conditions due to uneven mechanical loading, always install the heaviest devices in the bottom of the rack cabinet.
  • Page 10 CAUTION: Removing components from the upper positions in the rack cabinet improves rack stability during relocation. Follow these general guidelines whenever you relocate a populated rack cabinet within a room or building: v Reduce the weight of the rack cabinet by removing equipment starting at the top of the rack cabinet.

    v In this configuration, the embedded SAS controller module provides support for disks without RAID (referred to as JBOD) or RAID drives. However, it does not provide write cache. v Solid-state drives (SSDs) and hard disk drives (HDDs) can never be mixed in the same disk enclosure. Example: SAS subsystem configuration with tape storage This example shows a storage backplane with tape storage.
  • Page 21 v Disk units can be placed in any of the disk backplane slots. v No separate SAS cables are required to connect the two embedded SAS RAID adapters to each other. The connection is contained within the backplane. v RAID 0, 5, 6, and 10 is supported. v Solid-state drives (SSDs) and hard disk drives (HDDs) can be used but can never be mixed in the same RAID array.
