Removing the blade server bezel assembly To install certain options, you must first remove the blade server bezel assembly. The following illustration shows how to remove the bezel assembly. Bezel-assembly release (both sides) Control-panel cable Bezel Control-panel connector To remove the blade server bezel assembly, complete the following steps: 1. Read the safety information that begins on page v and "Installation guidelines" on page 15. 2. If the blade server is installed in a BladeCenter unit, remove it (see "Removing the blade server from the BladeCenter unit" on page 17 for instructions). 3. Open the blade server cover (see "Opening the blade server cover" on page 18 for instructions). 4. If a Memory and I/O Expansion Blade is installed, remove it (see "Removing an expansion unit" on page 19). 5. Press the bezel-assembly release and pull the bezel assembly away from the blade server approximately 1.2 cm (0.5 inch). 6. Disconnect the control-panel cable from the control-panel connector. 7. Pull the bezel assembly away from the blade server. 8. Store the bezel assembly in a safe place. Installing a SAS hard disk drive The blade server has two connectors on the system board for installing optional SFF SAS hard disk drives. Depending on the blade server model, at least one SAS hard disk drive might already be installed. If the blade server is equipped with one SAS hard disk drive, you can install an additional SAS hard disk drive. These two SAS hard disk drives can be used to implement and manage a redundant array of independent disks (RAID) level-1 array. See "Configuring a RAID array" on page 47 for information about SAS RAID configuration. 20 BladeCenter HS21 Type 8853: Installation and User's Guide
