CANOGA PERKINS N525 Ethernet Termination Service Unit - Manual (Page 45)

N525 Ethernet Termination Service Unit 3-27
Update Software
Each N525 has two flash memory banks that store software:
1. The Active Flash Memory holds the software currently in use
2. The Inactive Flash Memory holds the new software from a download or the older version
of software
Software is downloaded to the inactive memory to avoid disrupting service. Resetting the N525
and swapping banks does not affect operation and is transparent to user traffic.
Use the Software Upgrade report and menu screen to check the current version of the firmware
and upgrade it and the remote N525, if necessary. To access the Software Upgrade Menu and
check the software version, follow these steps:
1. From the Main Menu, type [ 7 ], "Software Upgrade," and press <Enter>. The Software
Upgrade screen appears.
Note: Line 4 is only present when the remote unit is SBMC Connected N525.
2. Record the numbers for the Active and Inactive Firmware for both the local and remote
N525s.
3. Access the Canoga Perkins Web site, click Downloads, scroll to the N525 filename and
compare version numbers listed there with the version numbers you recorded. The
N525 firmware filename is similar to N5250106.zip, where N525 indicates the module
and 0106 indicates the version number.
4. Download the software from the Web site to your local TFTP, FTP, or SFTP server.
Caution: To ensure compatibility when two N525s are connected using the EXT ports,
you must upgrade all connected units with the same firmware. Failure to do so will
cause CFG alarms could result in user traffic disruption.
