• voltages in volts
• temperature in Celsius
• fan speeds in RPM
Recommended Action
If the message is isolated, it might be a transient problem with the sensor hardware; monitor the error
messages on the switch. If the message is persistent, without other environmental errors, replace the FRU.
If the message is persistent, and there are other associated environmental messages, follow the actions for
those messages.

Message
Probable Cause
Indicates that there are no cached sensor values for the sensor, and software was unable to read new
values.
The FRU ID value is composed of a FRU type string and an optional number to identify the unit, slot, or
port. The FRU ID value can be:
• Switch for fixed port count switches.
• Slot 1 through Slot 10 for the Core Switch 2/64, SAN Director 2/128, and 4/256 SAN Director.
• PS 1 through PS 4 (power supplies) for the Core Switch 2/64, SAN Director 2/128, and 4/256 SAN
Director, or PS 1 through PS 2 for the SAN Switch 2/32 and SAN Switch 4/32. The power supplies on
the SAN Switch 2/8V and the SAN Switch 2/16V are not field replaceable.
• Fan 1 through Fan 3 for the Core Switch 2/64, SAN Director 2/128, and SAN Switch 4/32 (six fans
in three FRUs). Fan 1 through Fan 6 for the SAN Switch 2/32 (six fans in three FRUs). The fans on the
SAN Switch 2/8V and the SAN Switch 2/16V are not field replaceable.
The SAN Switch 2/8V has one power supply and three fans, and the SAN Switch 2/16V has two power
supplies and four fans. Values for the individual fans and power supplies for these switches might display,
but these parts cannot be replaced: the entire switch is a FRU.
The does not have any fans, power supplies or WWN cards.
The 4/8 SAN Switch, 4/16 SAN Switch has 4 fans and 1 power supply, but these parts cannot be
replaced: the entire switch is a FRU. The 4/8 SAN Switch, 4/16 SAN Switch fans do not have RPM
sensors, so cannot display fan speed.
Recommended Action
If the message is isolated, it might be a transient problem with the sensor hardware; monitor the error
messages on the switch.
Try reseating the FRU. If the message persists, replace the FRU.
