Performing a Software Upgrade

Execute the Network (TFTP) command from the Load FLASH Set-Up

menu.

Enter “none” to connect locally or enter the remote site ID number or alias

to connect to a remote site.

Start the TFTP application to be used for transfers to the router.

(The IP address of the router may be found in the Internet Set-Up menu.).

Put the file “###.all” to the router from the Operational Code directory on

the CD-ROM.

(Any router not in Network Load BOOT mode will respond with an access

violation error.)

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 re-entered.

- 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.
