Monitoring Fan Modules
Monitoring Fan Modules
The fan status is continuously monitored. In case of a fan module failure, the following action is taken:
•
Syslog messages are displayed.
• Call Home alerts are sent (if configured).
•
SNMP notifications are sent (if configured).
Caution A fan failure could lead to temperature alarms if not corrected immediately.
When a fan module is removed, the Fan module removed message is displayed every 10 seconds for three
minutes after the fan removal. After the three-minute interval, a system shutdown message is displayed
every 5 seconds for two additional minutes. At the end of this 5-minute sequence, the system is
shutdown. If the fan module is re-inserted at any point within this 5-minute period, the remaining
sequence is stopped.
To monitor a fan module from Device Manager, choose Physical > Fans . The dialog box displays the
fan status.
Monitoring Clock Modules
Each switch has two clock modules for redundancy: Clock A (primary) and Clock B. The redundant
clock module (Clock B) takes over if the primary clock module fails. If Clock A is available at startup,
the switch uses Clock A, otherwise it uses Clock B.
If Clock A fails, the switch is reset and Clock B automatically takes over. Clock modules cannot be
configured. If both modules fail, the switch shuts down. The probability of a clock failure is low given
that the mean time between failures (MTBF) is 3660316 hours.
Viewing System Attributes
To manage system attributes, perform the following steps.
Step 1 From the Fabric Manager menu tree, choose Switches , or from Device Manager, choose Admin >
System . You can also double-click on the chassis in Device Manager.
The Fabric Manager Information pane shows system attributes for multiple switches. The dialog box
from the Device Manager shows system attributes for a single switch.
Step 2 Configure the system attributes for the chassis.
Viewing Running Processes
You can view information about the processes that are currently running on a switch from Device
Manager. Choose
Admin > Running processes to see the process information listed in the Running
Processes dialog box.
