OPM_CNT_SNM_BAS_CRD_1GB_V012.doc Operating Manual SNMP/Web Adapter
5 NETWORK CONFIGURATION
The SNMP/Web adapter network interface is very flexible and can be configured for operation in various
environments. This section details all possible network configuration combinations, while it is
recommended to refer to Console/Web interface sections for the specific configuration commands /
menus.
5.1 ETHERNET CONNECTION
As most advanced network devices, SNMP/Web adapters use an autonegotiation protocol to
communicate what media technologies are supported, and then select the fastest mutually supported
media technology.
In this context, media refers to a 10baseT/100baseTx Ethernet connection in Half-Duplex (HD) or Full-
Duplex (FD) mode. The SNMP/Web adapters advertise and support the following media:
• 100baseTx-FD
• 100baseTx-HD
• 10baseT-FD
• 10baseT-HD
This autonegotiation feature is enabled by default. However, some passive devices, such as single-
speed hubs, are unable to autonegotiate. To handle such devices, the SNMP/Web adapter can be forced
to operate in one specific mode, instead of autonegotiating.
5.2 TCP/IP CONFIGURATION
TCP/IP configuration refers to the settings needed by an SNMP/Web adapter to operate in a TCP/IP
network. The selection of the boot method is critical for successful SNMP/Web adapter configuration.
The SNMP/Web adapters support the following boot methods:
• Static IP
• BOOTP
• DHCP
The default configuration is DHCP support.
5.2.1 Static IP address
In this case, the TCP/IP settings are manually configured on the adapter, and stored in non-volatile
memory. Particularly, the following need to be specified:
• IP address: IP address of the SNMP/Web adapter
• Subnet Mask
• Default gateway: IP address of the default gateway
NOTE: These settings are only available when the boot method is set to Static IP.
5.2.2 BOOTP / DHCP
In this case, the SNMP/Web adapter automatically obtains the TCP/IP settings respectively from a
BOOTP or a DHCP server.
The default configuration for the SNMP/Web adapters is DHCP support.
If the adapter IP-address is used by other network nodes for accessing UPS information (e.g. NMS
systems), make sure the DHCP server assigns a fixed IP to the SNMP adapter.
NOTE: For details on BOOTP and DHCP protocol refer respectively to RFC951 and RFC2131.
