In the getmodinfo command response, the PS-1..PS-4 Module indicates the power state and health
condition of the PSU. If any of the PSUs is not functioning, it may indicate as Failed in the Power
State, Critical or Not OK in Health. In that case, service the PSU.
Troubleshooting Fan Modules
The Fan modules on VRTX Chassis are hot-pluggable devices. VRTX Chassis has two types of fans
―Blowers and internal storage fans. It is advised to remove and replace only one fan module at a
time in a system that is turned on. Removal of all the internal fans at one time may cause the chassis
to overheat, resulting in a thermal fault and the turning off of various components. Each Fan module
has indicators that identify a non-functioning fan, or by running the getmodinfo RACADM command.
For any fan issues related to the fans, VRTX Chassis will log a message to the SEL Log or the Chassis
Log.
From the sample output defined in the Getmodinfo racadm command response, fan 1―fan 6 and
blower 1―blower 4 are the fans, the powerstate and health field reflect the state and health of a fan.
If the health state of a fan is not okay, it is advised to remove the fan and replace it. If fan–3, which
is the CMC fan, is not functioning, it may result in the generation of a Pfault in the SEL Log and the
chassis not powering on. If the problem is not resolved after a chassis powercycle, replace the fan.
Internal Chassis Fans can be set to different fan speeds running the racadm fanoffset command
in cases of the internal fan zone requiring more air flow.
- Disable the fan-offset feature
racadm fanoffset -s off
- Increase fan speed by 20% of fan's maximum speed.
racadm fanoffset -s low
- Increases fan speed by 50% of a fan's maximum speed.
racadm fanoffset -s medium
- Set fan to run at 100% of a fan's maximum speed
racadm fanoffset -s high
