RMM Firmware Update Procedures
To update RMM firmware, you need to have a TFTP server configured on your
network. The firmware can be installed using telnet or using Sentral. You need to first
install the firmware on the Primary RMM of each Chassis Group, and then propagate
the firmware update to the rest of the RMMs in the group.
Although downgrading a firmware version is possible with the RMM architecture, it is
never recommended.
NOTE: Do not remove any R4300 modules when updating the RMM firmware. This
can cause the firmware to become corrupted. The HEALTH LED on the RMM
displays an amber signal when firmware is being updated.
Updating RMM Firmware with Telnet
To install an RMM firmware update using telnet, do the following:
1. Download the firmware update package from the ClearCube Support website.
2. Unzip the package, and copy the files to the directory where the TFTP server is
configured to get the file.
3. Telnet into the Primary RMM and verify your RMM firmware version.
a. Telnet into the Primary RMM by entering the following at a command prompt:
telnet RMMIPAddress
where
RMMIPAddress is the IP address for the RMM.
b. Log in to the RMM, and enter the following command:
ver
If the RMM is version 5.x or higher, continue with this procedure. If the RMM
is version 4.x or lower, contact ClearCube Technical Support.
4. Enter the following command to update the Primary RMM:
tftp rmm52b2 TFTPServerIPAddress
where
TFTPServerIPAddress is the IP address for the TFTP server.
The Primary RMM firmware will be updated along with firmware for the other
modules in this chassis. When the firmware update is completed, the RMM
restarts automatically.
5. After the RMM restarts, log into the RMM again and enter the following command:
sfw 0
The other RMMs and modules in this Chassis Group are updated.
