5.41.1 Review Agent Settings
During unit startup, the "SNMP" LED will light as the agent boots up, then it should blink at about one cycle
per second after boot up and during normal operation. Refer to Chapter 3 section 3.1 for the SNMP agent settings.
Be sure you have a valid IP address for the attached network, that the subnet mask is properly set and that the
default gateway is set if you wish to manage the FRM from a remote network.
Attach a network cable to the FRM's front panel LAN/SNMP connector using a straight cable if connecting to a
HUB or a cross over cable if connecting directly to another MDI device, such as direct connection to a workstation.
The Link LED should be on or flashing. No link LED means no link. From any PC on the network, confirm the
agent can be pinged.
Figure 5.1 Ping
The "ipconfig" command from a command window in NT will display the workstation's IP, subnet and
gateway settings. The "ping" command will send an ICMP protocol message to the agent, which in turn should
reply. If no reply, double check all network connects, connect directly from a workstation to the FRM, or as a last
resort replace the SNMP card of the FRM.
