Peripheral and Hard Drive Support Intel® Server Chassis SC5650 TPS 4.2 5.25-inch Peripheral Drive Bays The Intel® Server Chassis SC5650 supports two half-height 5.25-inch removable media peripheral devices, such as a magnetic/optical disk, CD-ROM drive, or tape drive. These peripherals can be up to 9 inches (228.6 mm) deep on the non-redundant power chassis. The 600-W redundant power supply is longer in length and will limit the drives to approximately 7.5inch maximum length. As a guideline, the maximum recommended power per device is 17W. Thermal performance of specific devices must be verified to ensure compliance to the manufacturer's specifications. The 5.25-inch peripherals can be inserted and removed without tools from the front of the chassis after taking off the access cover and removing the front bezel. The peripheral bay utilizes visual guide holes to correctly line up the position of peripheral drives. Locking slide levers push retaining pins into the drive to hold the drive securely in the bay. EMI shield panels are installed and should be retained in unused 5.25-inch bays to ensure proper cooling and EMI conformance. Note: Use caution when approaching the maximum level of integration for the 5.25-inch drive bays. Power consumption of the devices integrated needs must be carefully considered to ensure that the maximum power levels of the power supply are not exceeded. 4.3 Hot Swap Hard Disk Drive Bays The chassis can support either an active SAS/SATA or a passive SAS/SATA backplane. The backplanes provide platform support for hot-swap SAS or SATA hard drives. The passive backplane acts as a "pass-through" for the SAS/SATA data from the drives to the SAS/SATA controller on the baseboard or a SAS/SATA controller add-in card. It provides the physical requirements for the hot-swap capabilities. The active backplane has a built-in SAS controller that requires a SAS controller on the baseboard or a SAS add-in card for communication. The active SAS/SATA backplane reduces the number of required cables by using only two SAS/SATA connectors to drive up to six hard drives. When the hot swap drive bay is installed, a bi-color hard drive LED is located on each drive carrier to indicate specific drive failure or activity. For pedestal systems, these LEDs are visible upon opening the front bezel door. 4.3.1 Fixed Hard Drive Bay The Intel® Server Chassis SC5650 comes with a removable hard drive bay that can accept up to six cabled 3.5-inch x 1-inch hard drives. Power requirements for each individual hard drive may limit the maximum number of drives that can be integrated into an Intel® Server Chassis SC5650. The drive bay is designed to allow adequate airflow between drives, and no additional cooling fan is required. Drives must be installed in the order of slot 1, 3, 5 first (skipping slots) to ensure proper cooling. The drive bay is secured with a tool-less retention mechanism. Note: The hard drive bay must be pushed forward or removed to install the server board. 108 Revision 1.2 Intel order number E39531-004
