1.15.3.2 Temperature Sensors
There is an additional temperature sensor on the CFC200, monitored for high temperature alarms, and can be
queried for current readings via CLI and SNMP, but is not used to control the fan speeds. There are also tem-
perature sensors on the PSUs.
Note: The specific alarm on the CFC200 is “High Temperature” and is described in the Log Manual.
1.15.3.3 Temperature and Fan Control
The system controls the fan tray to include reading the IDPROM, monitoring temperature and fan speed, and
adjusting the fan speed. The user cannot change the fan speed settings (There is no support for SET FANMOD-
ULE SPEED like on 9100.) The user can query the fan speeds and temperature readings using CLI and SNMP,
the same as with the iMAP products. Unlike the iMAP products, the fan module cannot be administratively dis-
abled.
The SBx3112 is designed to operate at commercial temperatures over a temperature range from 0-40 degrees
Celsius. However, the fan tray on SBx3112 does have a cold temperature shutdown mode which is enabled
once the fan sensor drops to ~11C. When enabled, the cold temperature shutdown mode protects the fans by
turning them off. The system exits cold temperature shutdown when the fan sensor rises to ~15C, and the fans
resume operation.
1.15.3.4 Example Command Output
The following are examples of SYSTEM COOLING and FANMODULE commands and output. Note that in the
case that temperature sensors can not be read, for example because the card containing the sensor is not phys-
ically present, then the temperature for that sensor would be shown as “Not Available”.
