DHCP radio buttons
The DHCP On radio button directs the ISM 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. Contact the local system administrator to determine the correct choice for this
setting.
IP Address field
The IP Address field contains the IP address of the connected switcher. This value
is encoded in the switcher’s flash memory.
N For further information about IP addresses and subnetting see appendix A,
“Ethernet Connection”.
Valid IP addresses consist of four 1-, 2-, or 3-digit numeric subfields, properly called
octets, separated by dots (periods). Each octet can be numbered from 000 through
255. Leading zeroes, up to 3 digits total per octet, 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.
N 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 switcher and the mail server are not on the same subnet.
The gateway IP address has the same validity rules as the system IP address.
Subnet Mask field
The Subnet Mask field is used to determine whether the switcher is on the same
subnet as the mail server when you are subnetting. For more information, see
“Subnetting — A Primer”, in appendix A, “Ethernet Connection” .
MAC Address field
The Media Access Control (MAC) Address is hard-coded in the switcher and
cannot be changed.
Firmware field
This field shows the firmware version number. This field only changes when the
firmware is updated.
Model field
This field shows the model (ISM 824) and cannot be changed.
Part Number field
This field shows the ISM 824 part number (60-787-01) and cannot be changed.
