IDE drive Tray Riser card IDE connector 2 (J2) Short screws IDE connector 1 (J1) Attention: v Drives must be installed in the following order: IDE connector 1 (J1) first, then IDE connector 2 (J2). v Do not install a hard disk drive in IDE connector 2 if you intend to also install an optional I/O expansion card. The I/O expansion card occupies the same area as the second IDE hard disk drive. v Do not press on the top of the hard disk drive when installing it. Pressing the top could damage the hard disk drive. v IDE hard disk drives must be set to primary (master). See the documentation that came with your hard disk drive for instructions. Complete the following steps to install a 2.5-inch IDE hard disk drive: 1. Read the safety information beginning on page iii and "Installation guidelines" on page 71 2. If the blade server is operating, shut down the operating system by typing the shutdown -h now command. Refer to your operating system documentation. If the blade server was not turned off, press the power-control button (behind the blade-server control-panel door) to turn off the blade server. See "Blade server controls and LEDs" on page 14 for more information about the location of the power-control button. 3. Remove the blade server from the BladeCenter unit. (See "Removing the blade server from the BladeCenter unit" on page 73 for instructions.) Carefully place the blade server on a flat, static-protective surface. 4. Open the blade server cover. See "Opening the blade server cover" on page 74 for instructions. 5. Insert the riser card from the option kit into an IDE connector on the blade server system board. 6. Place the tray from the option kit over the riser card as shown in the preceding illustration, aligning the tray with the screws on the system board. Note the four screws that are under the four screw holes in the tray. Set the tray aside and remove the four screws. 76 BladeCenter JS20 Type 8842: Hardware Maintenance Manual and Troubleshooting Guide
