cnt2SysFanPresent

Module: CNT251-MIB

OID (symbolic): CNT251-MIB::cnt2SysFanPresent

OID (numeric): 1.3.6.1.4.1.333.2.5.1.10.1.2

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-only

Description: An indication if a power supply fan is operational in this network node.

What is cnt2SysFanPresent?

This read-only INTEGER indicates with yes or no whether a particular power-supply fan is operational in this network node. An admin relies on this to catch cooling failures before they lead to thermal shutdowns of the chassis. For example, a fan reporting no (not operational) alongside rising temperatures elsewhere in the system would prompt an urgent hardware replacement.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.333.2.5.1.10.1.2
snmpwalk -v2c -c public <target> CNT251-MIB::cnt2SysFanPresent

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.333.2.5.1.10.1.2.1
snmpget -v2c -c public <target> CNT251-MIB::cnt2SysFanPresent.1
