Fuses are fine. MCC card? Will pull all cards out next time we replace power supply (maint. man doing this himself to save $).

Many people assume that the power supply mounts firmly into the backplane, but there is actually a cord that it must mate with. Failure to seat that cord properly (i.e. just jabbing the PS into the bay) could cause the PS to appear bad. \| VBC Salinas \| Valley Baptist Church, Salinas - worship and prayer for Salinas California
