Emerson MONITORING OpenComms Manuel D’Utilisation

The System Information Menu seeks descriptive input to enable the 

unit to be identified. This data is readable via SNMP queries. The (“) 

character is not permitted in any of the descriptive fields

The Network Settings Menu configures network parameters essential 

for proper network operation. The network administrator or other per-

sonnel responsible for the network should be consulted for the proper 

parameters to be entered in this menu.
In the static mode, the IP address is entered. Use the standard four-

part dotted decimal format. The NetMask and Default Gateway 

should also be entered in dotted decimal format. The NetMask, also 

known as subnet mask, delineates devices on the same physical net-

work segment, versus devices that require the services of a network 

router for access to other networks. The Default Router is the address 

of default router on the local segment.

The OpenComms NIC supports DHCP and BOOTP if a DCHP or 

BOOTP server must exist on the network. When this feature is 

enabled, at boot-up the card will perform a DHCP or BOOTP request 

for configuration information, including automatic assignment of an 

IP address. If the card receives the information, no further requests 

are made. If, at boot-up, a response is not received, the card will con-

tinue to send a request approximately every 30 seconds until a 

response is received. When this condition is encountered, pushing the 

<Enter> key returns the unit to the service terminal mode.

The SNMP (Simple Network Management Protocol) Communications 

Menu specifies parameters particular to the SNMP interface. Commu-

nities are used as a means of security for SNMP v1; only specified 

hosts with the appropriate community name(s) are allowed to perform 

particular SNMP operations. Up to 20 different communities can be 

assigned.
For each community, specify the dotted decimal IP address of the 

remote host, the privilege level (read or read/write), and community 

name. Trap Communities specify the recipient(s) of SNMP trap mes-

sages generated by the OpenComms Network Interface Card. Typi-

cally; the recipient is the management station of the NMS. Specify the 

Consult your network administrator to ascertain the 

parameters appropriate to your network.
