  • Page 24: Memory Installation

    Populating Memory Slots The mainboard of a SBI-7426T-S3 blade module has twelve memory slots, depending upon the blade model. Both interleaved and non-interleaved memory are supported, so you may populate any number of DIMM slots. Populating three slots at a time (DIMM1A + DIMM2A + DIMM3A, etc.) with memory modules of the same size and of the same type will result in dual-channel, interleaved memory, which is faster than single-channel, non-interleaved memory.

  • Page 25: Figure 3-5. 12-Slot Dimm Numbering

    Chapter 3: Setup and Installation NOTE: The DIMM slot number specified in Table 3-1 equals the DIMM slot to be populated. A “---” indicates that the DIMM slot should be left unpopulated. NOTE: Though multiple DIMM memory module types and speeds may be supported, you need to use DIMM memory modules of the same speed and type.

    SBI-7426T-S3 Blade Module User’s Manual DIMM Installation WARNING: Exercise extreme care when installing or removing DIMM modules to prevent any possible damage. Installing DIMM Memory Modules 1. Power down the blade module (see "Powering Down a Blade Unit" on page 3-1).

  • Page 27: Hard Disk Drive Installation

    Chapter 3: Setup and Installation Hard Disk Drive Installation Hard disk drives are installed in “carriers” which are hot-swappable and can be removed or replaced without powering down the blade unit they reside in. A blade module needs a hard disk drive with an operating system installed to operate. WARNING: To maintain proper airflow, both hard drive bays must have drive carriers inserted during operation whether or not a drive is installed in the carrier.
