Extron electronic ISM 824 Dhcp radio buttons, Gateway IP Address field, Subnet Mask field

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.

NFor further information on 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.

NIP 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 hardcoded 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 show the model (ISM 824) and cannot be changed.

Part Number field

This field show the ISM 824 part number (60-787-01) and cannot be changed
