Attention: v To maintain proper system cooling, do not operate the BladeCenter unit for more than one minute for the BladeCenter unit and 20 minutes for the BladeCenter T unit without either a blade server, expansion unit, or filler blade installed in each blade bay. v Note the bay number. Reinstalling a blade server into a different bay than the one from which it was removed could have unintended consequences. Some configuration information and update options are established according to bay number; if you reinstall the blade server into a different bay, you might need to reconfigure the blade server. Complete the following steps to remove the blade server: 1. If the blade server is operating, shut down the operating system; then, 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 10). Attention: Wait at least 30 seconds, until the drives stop spinning, before proceeding to the next step. 2. Open the two release levers (see Figure 8 on page 29 and Figure 9 on page 29). The blade server moves out of the bay approximately 0.6 cm (0.25 inch). Note: You must remove the bezel assembly from the BladeCenter T unit before you can access the blade server. Firmly grip the blue touch points (at the top-left and top-right sides of the bezel) and forcefully pull forward, lifting the bezel up and away from the BladeCenter T unit. Carefully set the bezel assembly aside in a safe place (see the BladeCenter T Types 8720 and 8730 Installation and User's Guide for detailed information about reinstalling the bezel assembly). 3. Pull the blade server out of the bay. Spring-loaded doors farther back in the bay move into place to cover the bay temporarily. 4. Place either a filler blade or another blade server in the bay within one minute for the BladeCenter unit and 20 minutes for the BladeCenter T unit. The recessed spring-loaded doors will move out of the way as you insert the blade server. 30 BladeCenter HS20 Type 8832: Hardware Maintenance Manual and Troubleshooting Guide
