8.1.1 Network Manager Software Update Recovery
This section is applicable whenever unit power was lost during software update exactly whenever new software
was being written to the unit internal FLASH, causing the unit to become unmanageable over the Network while
PoE continues to work OK (unmanaged PoE Switch device).
The software update functionality is independent from the Network Manager software, meaning that even upon
software update failure and corruption due to unexpected power loss, the unit will still be able to recover by
itself by initiating by itself one of the two software update recovery procedures:
8.1.1.1 Software update recovery procedure #1 - same remote TFTP Server:
Upon power being restored the Unit will re initiate by itself after around one minute software update from the
same remote TFTP Server as it was instructed before power was lost. Upon successful self-initiated software
update completion, the unit will become manageable again. The entire recovery process should take less than
10 minutes.
8.1.1.2 Software update recovery procedure #2 - remote TFTP Server 192.168.0.50:
In case unit fail to re initiate software update from remote TFTP Server as it was instructed prior power loss (for
example TFTP Server IP is no longer valid, or unit was disconnected from the Network and moved to local LAN
Network), the unit will initiate by itself recovery procedure by trying to perform software update from TFTP
Server IP address 192.168.0.40 while assigning to itself IP address 192.168.0.50 regardless to the IPv4
address it was configured before power loss. Upon successful software update recovery, the unit will re assign
to itself the IPv4/v6 address it was configured prior software update procedure, and become manageable using
same IP address as before.
8.2 PoE Unit firmware software Update
PoE firmware is responsible for the actual PoE functionality of delivering PoE power, making sure that PD
device complies with PoE requirements, monitor PD power consumption, etc.
NOTE:
PoE firmware rarely has to be updated. Please make sure you need to perform PoE
firmware update rather than Network Manager software update.
PoE Firmware update via TFTP is very similar to Upload/Download Unit Configuration.
1. Activate and run TFTP Server.
2. Verify that the firewall on the computer running TFTP Server is Off, or accepts incoming UDP traffic on
port 69.
3. Copy the new PoE firmware files (as in the example below) to TFTP Server root folder (for example
d:\temp).
