This comprises a SAS expansion card attached to the blade server, a SAS switch in the rear of the chassis, and various options to attach storage to that integrated SAS switch. An optional SAS expansion card is available for the BladeCenter QS21. Storage can be attached via the external SAS host controller. The BladeCenter QS21 supports the SAS drives of the IBM System Storage™ DS3200 and the IBM System Storage EXP3000 expansion unit. Check the IBM BladeCenter support Web site for details of supported SAS drives at http://www.ibm.com/support/us/en/. Turning on the blade server The BladeCenter QS21 is hot-swappable and can be inserted into the BladeCenter unit when the unit is already powered up. However, it can only be powered on by one of the methods described in this section. While the blade server is powering up, the power-on LED on the front of the server is lit. See "Blade server controls and LEDs" on page 6 for the power-on LED states. After you have installed the BladeCenter QS21 into a powered up BladeCenter unit, wait until the power on LED on the blade server flashes slowly before turning on the blade server. You can turn on the blade server in any of the following ways: Using the power control button You can press the power-control button Figure 1 on page 4 which is behind the control-panel door on the front of the blade server if local power control is enabled for the blade server. Local power control is enabled and disabled through the BladeCenter Management Module Web interface. Chapter 1. Introduction 3
