chEnvFanAdmin

Module: CTRON-ENVIRONMENT-MIB

OID (symbolic): CTRON-ENVIRONMENT-MIB::chEnvFanAdmin

OID (numeric): 1.3.6.1.4.1.52.4.1.1.8.1.12.1.3

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: This object is used to select the operational mode of the fan. If the value is set to 1 (auto) then fan speed is based on temperature. If the value is set to 3 (testing) then value will return to it's previous value prior to being set at 3.

What is chEnvFanAdmin?

This is the administrator-selected operating mode for the chassis fans, choosing between automatic temperature-based speed control, forced full speed, or a temporary test mode that reverts to its prior value afterward. It lets an admin override automatic cooling control when needed, such as during a thermal stress test. For example, setting this to fullSpeed(2) during a heat wave forces maximum cooling regardless of the temperature-based automatic algorithm.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.52.4.1.1.8.1.12.1.3
snmpwalk -v2c -c public <target> CTRON-ENVIRONMENT-MIB::chEnvFanAdmin

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.52.4.1.1.8.1.12.1.3.1
snmpget -v2c -c public <target> CTRON-ENVIRONMENT-MIB::chEnvFanAdmin.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.52.4.1.1.8.1.12.1.3.1 i <value>
