Replacement CM 4000
K−3CM 4000 Installation and Operating Manual
The current Ethernet address will be displayed:
Current Ethernet Address is: 00:40:53:12:34:56
The first 3 bytes of the Ethernet address are the manufacturer’s ID and cannot be changed. The fourth byte will
be shown with an option to change it:
00− 00
40− 40
53− 53
12− _
e. Modify the last 3 bytes to match those of the failed CM 4000.
Enter the new digits and press Enter to change Byte 4 or press Enter alone to keep the current byte. In this example,
the 4
th
byte is changed to “21.”
12− 21 [ENTER]
Repeat the process for the remaining two bytes. In this example, the 5
th
byte will be kept the same, and the 6
th
byte changed to ”65”:
34− [ENTER]
56− 65 [ENTER]
f. The EEPROM will now be re−written. During this time, do not reset the CM 4000 or allow the power to reset.
Writing EEPROM .....
When the write cycle is complete, the new current Ethernet address will be displayed with the vxWorks prompt:
New Ethernet Address is: 00:40:53:21:34:65
[VxWorks Boot]:
Make a note of this number (e.g., by writing it on the CM back panel).
g. Remove power from the CM 4000.
4. Make sure that power has been removed from the faulty CM 4000, then disconnect it from the system while noting cable
positions.
5. Install, connect, and power up the replacement CM 4000.
The replacement CM 4000 will boot up automatically. The other CM 4000 should remain active throughout this opera-
tion.
6. Confirm that the system is still operating normally by using a Jupiter control panel.
Ensure that the status of all crosspoints on the switcher is reported on the panel.
