NOTE: SAS and SATA hard drives cannot be mixed within a blade. NOTE: Hot-plug operation is supported if an optional RAID controller card is installed. NOTE: SATA hard drives are not hot swappable with the SATA repeater daughter card. Hard Drive Installation Guidelines • If a RAID controller storage card is installed, the blade supports hot-plug drive removal and installation. • If less than the maximum number of hard drives are installed, hard drive blanks must be installed to maintain proper cooling airflow. Installing a Hard Drive NOTE: When a replacement hot-swappable hard drive is installed and the blade is powered on, the hard drive automatically begins to rebuild. Make absolutely sure that the replacement hard drive is blank or contains data that you wish to have over-written. Any data on the replacement hard drive is immediately lost after the hard drive is installed. NOTE: Not all operating systems support hot-plug drive installation. See the documentation supplied with your operating system. 1 Open the hard-drive carrier handle. See Figure 3-53. Installing Blade Components 247
