Performing a Software Upgrade
1)Execute the Network (TFTP) command from the Load FLASH
2)Enter “none” to connect locally or enter the remote site ID number or alias to connect to a remote site.
3)Start the TFTP application to be used for transfers to the router. (The IP address of the router may be found in the Internet
4)Put the file “###.all” to the router from the Operational Code directory on the
(Any router not in Network Load BOOT mode will respond with an access violation error.)
5)The router will verify the file “###.all” in memory, program and verify the FLASH, clear the configuration to default values (except: IP Address, IP Routing state, IP Forwarding state, WAN Environment, Link 1 & 2 State, the Switch Type, Directory Numbers, SPIDs, Password and connection data for the remote site, if applicable), and then reset. After the reset, the router will operate normally using the newly upgraded software. In some upgrade situations the Directory Numbers and SPIDs may be corrupted after the upgrade and will need to be
-The router may take up to two (2) minutes to program and verify the FLASH. The console will not respond during this time.
To check on the router’s current state during this process, get the file “status.txt” from the router. This file will report the router’s state: both the mode and version if no errors have occurred, or an error message.
On the rare occasion that during the programming of the FLASH something happens to the bridge/router (power hit or hardware reset), causing the FLASH to become corrupted, the bridge/router will restart in ZMODEM receive mode only. If the bridge/router does not start in ZMODEM receive mode: power down the bridge/router, remove the WAN module(s) and, if present, the second LAN module, power up the bridge/router. The bridge/router should now restart and be in ZMODEM receive mode. Once the file transfer is complete, the router will again come up in ZMODEM receive mode. Power down the unit and replace the interface modules.
