Hello, when I insert NM-2FE2W module in cisco 3640 I get the following message on the console screen: *Mar 1 00:00:07.243: %FECPM-3-TDMSW: TDM switch init in slot 2 failed -Traceback= 602430B0 6023D5E4 60591178 60591268 604F160C 60404228 6040443C 604D91F0 604D91D4 *Mar 1 00:00:07.247: %FECPM-1-INITFAIL: NM slot 2: PCI dev 8 init failed *Mar 1 00:00:07.335: %FECPM-1-DISCOVER: NM slot 2: only 2 PCI dev found My IOS version is: c3640-i-mz.123-4.T2.bin" . I tried to power off, insert the module again in different slot, but it didn't help. Can anyone help me with this problem? Nice regards, Ivana
