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 Ipconfig and 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.
