Will a CE switch generate alarms if it has only one fan module or power module installed

21

Description
Will a switch generate an alarm if it has only one power module or fan module installed?
Solution
If only one power module is installed in a switch, the switch generates power module absence alarms for the idle power slots.

In this case, the switch generates fan module absence alarms for idle fan slots, and fans in the present fan module work at full speed.

Description:
  • The CE5800 series supports 1+1 redundancy of power modules and fan modules. A CE5800 switch can work normally with a single power module or fan module installed, but the device reliability degrades in this case.
  • The CE6800 switches support 1+1 redundancy of power modules. A CE6800 chassis uses two FAN-EA series fan modules. Each fan module contains two fans. The four fans in the chassis work in 3+1 backup mode.

Description
What will occur if power modules or fan modules used on a switch have different airflow directions?
Solution
If power modules or fan modules used on a CE switch have different airflow directions, the system reports alarms about inconsistent airflow directions of the power modules and fan modules. Inconsistent airflow directions between power modules, fan modules, or between power modules and fan modules degrade system reliability when the switch needs to work in a high-temperature environment for a long time, and shorten service life of the switch.

Whether a blade server can be configured with only one switch module
A blade server configured with only one switch module can still ensure network connectivity. However, link redundancy is affected. For more details, see the user guide.
