Top Cover Removal/Replacement The disk enclosure top cover is not a replaceable part, however it must be removed when replacing the power button assembly, the backplane, or the mezzanine board. The disk enclosure must be powered down to perform this procedure. The top cover must be replaced by a trained service representative only. CAUTION All disk modules must be removed from the enclosure before removing the top cover. 1. Power off the disk enclosure and slide it out of the rack about 10 inches. See "Disk Enclosure SC10" on page 304. 2. Remove all disk modules and fillers. See "Disk Module or Filler Module" on page 291. CAUTION Removing the top cover with the power switch in the ON position can damage the internal switch. 3. Remove the nine T-10 screws from the back and side edges of the cover plate (A in Figure 100). Screws are marked by a star pattern in the sheet metal. 4. Slide the cover forward about one inch, then lift it up and off the enclosure. 5. When you are ready to replace the cover, set the cover on the chassis so that the tabs (C in Figure 100) settle into the slots in the upper edge of the chassis. 310 Internal Disk Enclosure Assemblies
