5.5.5 SNMP Settings
Using SNMP, users can easily manage system performance and remotely find
and solve system problems. The HFE LAN serves as an SNMP Agent. A SNMP Host
system is used to communicate with this SNMP agent.
A key part of the SNMP protocol is the Management Information Base (MIB) that
describes all Agent variables that can be accessed. The MIB will be needed by any
SNMP Host that wishes to communicate with the HFE LAN and can be retrieved
from: https://uk.tdk-lambda.com/products/product-details.aspx?scid=304
HFE LAN utilizes four operations to respond to Host: Get, GetNext, Set and Trap
Get – Allows the Host to retrieve a value from the HFE LAN.
GetNext – Allows the Host to retrieve the next value from a list of variables
in HFE LAN.
Set – Allows the Host to set a value within the HFE LAN
Trap – Used by the HFE LAN to inform the Host of an event. The HFE LAN
must be configured with appropriate address of the Host.
SNMP Service: Service can be enabled or disabled.
Community: Always public.
Traps Enabled:
There are 3 types of traps
1. Link Up – Whenever a new link is made.
2. Cold Start – Whenever LAN settings are changed.
3. Faults PS - At any power supply fault.
Any of them can be enabled or disabled.
Traps Address: Address and port number of the Host where traps are received.
Note: AC Fail trap may not be detected at high load condition due to power
supply’s short hold up time.
