Installing a Blade 1 If you are installing a new blade, remove the plastic cover from the I/O connector(s) and save for future use. See Figure 3-3. 2 Orient the blade so that the handle is on the left side of the blade. 3 If you are installing a blade in one of the eight upper bays, align the guide rail on the upper edge of the blade so that the rail fits between the plastic guides on the enclosure. If you are installing a half-height blade in one of the eight lower bays, align the edge of the blade with the guide rail on the floor of the M1000e enclosure. If you are installing a full-height blade in bays 1 or 2 or a half-height blade in bays 12 or 13, rotate the LCD module to the horizontal storage position to prevent accidental damage to the LCD screen. 4 Slide the blade into the enclosure until the handle engages and locks the blade in place. Removing and Installing a Blade Blank CAUTION: If you are permanently removing the blade, install a blade blank. (A full-height blade requires two blade blanks.) Operating the system for extended periods of time without a blade blank installed can cause the enclosure to overheat. See "Installing a Blade Blank" on page 149. Removing a Blade Blank If you are removing a blade blank from one of the eight upper bays, press the blue latch at the upper edge of the blank faceplate and slide the blank out of the enclosure. If you are removing a blade blank from one of the eight lower bays, press the blue latch at the lower edge of the blank faceplate, and slide the blank out of the enclosure. 148 Installing Blade Components
