Menus Reference Manual: Load FLASH Set-Up Menu
1 - Console (ZMODEM)
Resets the router and places it in Console load mode. Once the router is in Console load mode, the "###.all" file may
be sent using the ZMODEM transfer protocol. The Console load mode may only be used with a direct connection to
the serial management port of the router.
The ZMODEM application must be in 32 bit CRC mode for software upgrade transfers.
This option must be confirmed before operation by typing "yes" when prompted.
Procedures for performing a Console ZMODEM Flash Load to upgrade the operating software of the router:
1) Save the current configuration of the router (Main menu: option 6).
2)
Execute the Console (ZMODEM) command from the Load FLASH Set-Up menu.
Confirmation is required. Enter "yes" to proceed.
3)
After the router restarts, the router will be in receive ZMODEM mode. The router will display the following
messages on the console port.
System startup
Receiving ZMODEM ...
**B0100000023be50
4)
Start the ZMODEM transfer and send the file "###.all" from the the Operational/Boot Code directory on
the CD-ROM.
5)
Once the ZMODEM transfer is complete, the router will verify the file "###.all" in memory, program and verify
the FLASH, clear the configuration to default values (except the password), and then reset. After the reset, the
router will operate normally using the newly upgraded software. A byte status message will be displayed on the
console port during the programming of the FLASH.
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, open
the case, locate jumper W4 on the main circuit board (it is next to the batteries), put the jumper across pins 1-2,
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 return
the W4 jumper to pin positions 2-3. Please refer to the Servicing Information section of the Installation &
Applications Guide for information on removing the case and changing the strap settings.
The ZMODEM Load Flash operation may be aborted (by aborting the ZMODEM transfer and then entering
5 control-X characters "^X" from the console keyboard. After the control-X characters are sent, the router will display
a limited menu system. Choose the Abort Load option from the Load FLASH Set-Up menu. This will cause the router
to reset and return to normal operations operating from the existing software.
If the ZMODEM transfer operation needs to be restarted after it has been canceled or after loading the first file, simply
choose the Console (ZMODEM) option from the Load FLASH Set-Up menu once again.
Considerations:
When the router is placed in Console load BOOT mode, the LAN and WAN interfaces will be disabled. The router
will only accept information from the console management port.
The BOOT code of the P1700 may be upgraded by performing a load of the "###.all" file from the the
Operational/Boot Code directory on the CD-ROM.
Maximum connection speed for ZMODEM transfer on a P1700 is 38400 Bps.
