DVS 510 Series • HTML Configuration and Control 89
IP Settings Fields
The IP Settings fields let you view and edit settings unique to the Ethernet interface. After
editing any of the IP settings, click the Submit button at the bottom of this section.
Unit Name field
The Unit Name field contains the name used as the “from” information when the DVS
e-mails notification of its failed or repaired status. You can change this name field to any
valid name, up to 24 alphanumeric characters.
NOTE: The following characters are invalid or not recommended in the name:
+ ~ , @ = [ ] { } < > ’ ‘ “ ” ; : | \ and ?.
DHCP radio buttons
The DHCP On radio button directs the DVS to ignore any entered IP addresses and to obtain
its IP address from a Dynamic Host Configuration Protocol (DHCP) server (if the network is
DHCP capable).
The DHCP Off radio button turns DHCP off (default).
Contact your local system administrator for this setting.
IP Address field
The IP Address field contains the IP address of the connected DVS. This address is encoded
in the scaler flash memory.
Valid IP addresses consist of four octets: one-, two-, or three-digit numeric sub-fields
separated by periods. Each octet can be numbered from 000 through 255. Leading zeros,
up to three digits total per field, are optional. Values of 256 and above are invalid.
The factory-installed default address is 192.168.254.254, but if this conflicts with other
equipment at your installation, you can change the IP address to any valid value.
NOTE: IP address changes can cause conflicts with other equipment. Only local system
administrators should change IP addresses.
Gateway IP Address field
The Gateway IP Address field identifies the address of the gateway (to the mail server) to
be used if the scaler and the mail server are not on the same subnet.
The gateway IP address has the same validity rules as the system IP address (see “IP Address
field,” above).
Subnet Mask field
The Subnet Mask field is used to determine whether the scaler is on the same subnet as
the mail server when you are using a subnet (see “Subnetting, a Primer” on page 120 for
more information).
The subnet mask address has the same validity rules as the system IP and gateway IP
addresses.
MAC Address field
The MAC (media access control) address is a unique hardware address by which each
individual DVS 510 can be identified. It consists of six pairs of characters separated by
hyphens. For all Extron products, the first three character pairs are 00-05-A6, followed by
three more pairs unique to the individual device. The MAC address is hard coded in the
scaler and cannot be changed.
