7Managing the deviceIf an I2C failure has not occurred, there will be no I2C messages in the static log, dynamic log, orSNMP log server. The following example shows output from the show logging comm<strong>and</strong> when thereis no I2C failure.<strong>Brocade</strong># show loggingSyslog logging: enabled (0 messages dropped, 0 flushes, 1 overruns)Buffer logging: level ACDMEINW, 50 messages loggedlevel code: A=alert C=critical D=debugging M=emergency E=errorI=informational N=notification W=warningStatic Log Buffer:Apr 16 18:21:25:A:System: Power Supply 2 , middle, Not Installed (FAILED)Apr 16 18:21:25:A:System: Power Supply 3 , top, Not Installed (FAILED)Dynamic Log Buffer (50 lines):Mar 28 12:36:47:A:System: Set fan speed to MED (75%)Mar 25 21:40:47:A:System: Set fan speed to MED-HI (90%)Mar 25 16:30:47:A:System: Set fan speed to MED (75%)Mar 23 23:12:07:A:System: Set fan speed to MED-HI (90%)If the system detects a major I2C failure, the system prevents the management module fromaccessing devices through the l2C serial bus.
