Hi everyone, I have a Cisco 1751 wich just wont boot (with no WIC or VIC inserted, all 3 slots are empty). When it powers on, the console output is as following: System Bootstrap, Version 12.2(1r)XE1, RELEASE SOFTWARE (fc1) TAC Support: http://www.cisco.com/cgi-bin/ibld/view.pl?i=support Copyright (c) 2001 by cisco Systems, Inc. C1700 platform with *** Machine Check Exception *** PC = ÿ Then, it boots again and the same output occurs repeatedly. The OK LED diagnostic is not aplying, I´ve read the "Cisco 1751 Router Hardware Installation Guide" (at  http://www.cisco.com/en/US/docs/routers/access/1700/1751/hardware/installation/guide/Trbshoot.html#wp1015229) and as you can see in table Table 3-1 OK LED Blinking Patterns, there are only 6 blinking chances, but my router´s OK LED blinks 14 times!!! I´ve tried 3 diferrent DRAM modules (previusly verified on other working chassis) and the very same situation repeats always. I´m thinking in a Hardware problem, but no shure if I should check something else! Any suggestions? Thank you and regards, Bob Sparkling ... View more
