Backplane/Mezzanine Removal/Replacement Replace the backplane when troubleshooting determines it is the source of the problem. Disks, BCCs, fans, and power supplies connect to the backplane. The backplane also contains the mezzanine board, which can be replaced independently if it is damaged or the power switch requires replacement. (The mezzanine board contains the power switch.) The backplane and mezzanine boards must be replaced by a trained service representative only. Also, the disk enclosure will need to be powered down to complete this procedure. To replace the backplane or mezzanine boards, complete the following steps: 1. Power off the disk enclosure and remove it from the rack. See "Disk Enclosure SC10" on page 304. 2. Remove the top cover. See "Top Cover Removal/Replacement" on page 310. 3. If you are removing only the mezzanine: a. Remove the five Torx T-10 screws securing the mezzanine to the backplane (see Figure 102). b. Pull the mezzanine board free of its connector (C) on the backplane. 314 Internal Disk Enclosure Assemblies
