Webpages
The SEL-2890 provides an HTTP server with a default webpage. You can use this
webpage or create your own. Setting WEB=SEL will enable the SEL default webpage
interface for a relay. You can use the SEL default webpage to display data and settings
information from an SEL relay connected to the SEL-2890 serial port. For an example
webpage, see
Figure 1.2 . Setting WEB=USER will provide a webpage that is identical
to the default with the following exceptions: you can download a nodelist.txt and a
logo.jpg file that will replace the tree menu and logo on the default webpage. No
HTML code is needed to accomplish this task. You can create and download a
completely custom webpage interface by setting WEB=CUSTOM. You can also turn
this feature off by setting WEB=OFF.
NOTE:
You may FTP the Nodelist.txt file out of the SEL
folder in the transceiver to view its contents. For more
information, please contact SEL.
Enable DHCP
DHCP stands for Dynamic Host Configuration Protocol. Setting DHCP to “Yes” will
allow a DHCP server to dynamically assign an IP to the SEL-2890. You should set up a
unique host name if you use DHCP. This will allow you to refer to the transceiver by
name rather than IP. Refrain from using DHCP if you are using serial tunneling. Use a
static IP address instead. When you use DHCP, the following settings are overridden:
DNS_IP, DOMAIN, IP, SUBNET_MASK, and GATEWAY. If the HOST_NAME is
left blank, the SEL-2890 will request it from the DHCP server. If a HOST_NAME is
entered, it will be provided to the DHCP server. This provides the ability to configure
the SEL-2890 HOST_NAME centrally at the DHCP server.
Domain Name Server IP
The domain name server (DNS) on a network translates or resolves an IED’s IP address
(e.g., 192.168.0.11) from its alphanumeric domain name (e.g., domain.com). Contact
your network administrator to obtain a DNS IP. The DNS IP will be automatically set
by the DHCP server if DHCP=Y.
Domain Name
Domain name of the domain name server. Contact your network administrator to
obtain a domain name. The domain name will be automatically set by the DHCP server
if DHCP=Y. To remove the domain name field, enter a space and press
<Enter> at the
change settings prompt.
Transceiver Host Name
The host name is the unique, common name that you assign to your transceiver. The
host name is virtually required when using DHCP because the IP address is not static.
Referring to an IED by host name is more convenient than by IP address. To take
advantage of this, your network has to be set up to recognize host names. Then the
