Power Problems Power problems may be seen on one or both transports. If one transport is affected, F1 or F2 may have failed. If either has, it should be repleced and the system tested to see if the fuse blows again. If it does, troubleshot the power suply path. If the problem is on both transports, check F201, look for the main power light and listen for the fan. You might have to troubleshoot the AC supply path.
