Configuring the MPX 866 A Matrix Switcher for Network Use via the
ARP Command
The ARP (address resolution protocol) command tells your computer to associate the
MAC (media access control) address of the MPX 866 A matrix switcher with the assigned
IP address. You must then use the ping utility to access the controller, at which point the
IP address of the controller is reconfigured.
Use ARP to congure the IP address as follows:
1. Obtain a valid IP address for the MPX 866 A matrix switcher from your network
administrator.
2. Obtain the MAC address (UID #) of the MPX 866 A matrix switcher from the label on its
rear panel. The MAC address should have this format: 00-05-A6-xx-xx-xx.
3. If the MPX 866 A matrix switcher has never been configured and is still set for factory
defaults, proceed to step 4. If not, perform a mode 4 system reset and then proceed to
step 4. For detailed information on reset modes, see Performing Soft System Resets
(Resets 3, 4, and 5).
NOTE: The MPX 866 A matrix switcher must be configured with the factory default
IP address (192.168.254.254) before the ARP command is executed, as
described below.
4. At the PC, access the Command prompt (see Pinging to Determine the Extron IP
Address, steps 1 through 3), then enter the arp –s command. Type in the desired new
IP address for the unit (obtained in step 1) and the MAC address of the unit (from the
rear panel of the unit), for example
arp –s 10.13.197.7 00-05-A6-03-69-B0 and then press {Enter}.
The computer returns the command prompt (C:\).
After you issue the arp -s command, the controller changes to the new address and
starts responding to the ping requests to the new address, as described in the next step.
NOTE: You must ping the MPX 866 A matrix switcher for the IP address change
to take place. The response should show the new IP address, as shown in
figure 71.
5. Execute a ping command by entering ping followed by a space and the new IP address
at the command prompt. For example:
ping 10.13.197.7
C:\>ping 10.13.197.7
Pinging 10.13.197.7 with 32 bytes of data:
