Managing the device
If an I2C failure has not occurred, there will be no I2C messages in the static log, dynamic log, or
SNMP log server. The following example shows output from the show logging command when there
is no I2C failure.
Brocade# show logging
Syslog logging: enabled (0 messages dropped, 0 flushes, 1 overruns)
Buffer logging: level ACDMEINW, 50 messages logged
level code: A=alert C=critical D=debugging M=emergency E=error
I=informational N=notification W=warning
Static 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 from
accessing devices through the l2C serial bus. The output from the show chassis command and the
show temperature command reflect this action, as shown in these examples.
Brocade# show chassis
*** Note: ***
*** Global I2C Error Indicator is set (severity: Major). ***
*** All I2C access are skipped. ***
