5−14 CM 4000 Installation and Operating Manual
Caution: Once the activate/reboot command has been issued, do not interrupt the process until the reboot is
complete. Interruptions such as sending a new command, turning off power, or disconnecting cables will
have unpredictable consequences. With a CM 4000, such consequences can include corruption of data stored
in flash memory and on the CM hard drive.
After a few seconds, the LEDs on the controller boards will turn red momentarily and the message “Device not con-
nected” or “Startup” will appear on the system control panels. When the download is complete, the LEDs should be
green and the panels returned to their previous status display. Depending on several factors such as the number of boards,
configuration size, need to update the *.sys file, LAN transmission rate, LAN traffic, etc., a complete set change can
take several seconds or multiple minutes.
Download status can also be determined using the Control Center “Board Status” tab.
For more information about Control Center functions, including the “Reboot” and “Restore Backup” buttons, see page
9−1.
Note: special procedures are available for CM 4000 systems to minimize system downtime during set activa-
tion. See “Download Now / Reboot Later” on page 5−15.
