AVAYA: IPO Office FAQ

DTE Port Maintenance
Posted: 2 Jan 06 (Edited 19 Dec 06)

Overview
The DTE port on the back of an IP Office Control Unit is not normally used when configuring an IP Office system. However the DTE port can be used to erase the system's operational software and/or configuration if
necessary.

Due to the drastic nature of these actions they should only be performed if absolutely necessary to return a system back to working order. In either case you must ensure that you have a backup copy of the system configuration.

DTE Port Settings
Access to the DTE port requires a serial cable between your PC/Laptop and the IP Office (such as a standard modem cable).

DTE PORT on 403 & 406v1 units: 25 pin.
DTE PORT on SOE, 406v2 & 412 units: 9 pin.

Also required is an asynchronous terminal program such as HyperTerminal.

Configure this for operation via a PC serial port, as follows:
ò Bits per second: 38,400.
ò Data bits: 8.
ò Parity: None.
ò Stop Bits: 1.
ò Flow Control: None.
ò Settings | Emulation: TTY or VT100.


Finding Out the Loader Version
It may sometimes be necessary to find out the version of Loader software on the IP Office Control Unit.
1. Switch off power to the IP Office Control Unit.
2. Attach the serial cable between the PC and the DTE port on the IP Office Control Unit.
3. Start the terminal program on your PC. Ensure that it has been setup as listed in DTE Port Settings above.
ò Within a HyperTerminal session the current settings are
summarized across the base of the screen.
4. Power on the IP Office Control Unit and press the escape key every second until you get a Loader message. Below is an example.
PremiSys Loader 0.6 (4MB-2xLV160 Flash-120nS SDRAM-10)
CPU Revision 0x0501

5. To return the IP Office Control Unit to normal operation switch power to it off and then back on.
6. Close the terminal program session.

Erasing the Flash Configuration
This process erases the configuration held in the IP Office Control Unit's Flash memory. Following this action, when rebooted all aspects of the configuration will be return to their factory defaults.
ENSURE THAT YOU HAVE A BACKUP COPY OF THE IP OFFICE'S CONFIGURATION
before performing this action.


1. Switch off power to the IP Office Control Unit.
2. Attach the serial cable between the PC and the DTE port on the IP Office Control Unit.
3. Start the terminal program on your PC. Ensure that it has been setup as listed in DTE Port Settings above.
ò Within a HyperTerminal session the current settings are
summarized across the base of the screen.
7. Power on the Control Unit and press the escape key every second until you get a Loader message.
4. Enter AT (note upper case). The Control Unit should respond OK.
5. Enter AT-X2. The Control Unit should respond 0x0200C000H Erase.
6. Enter AT-X3. The Control Unit should respond 0x02001000H Erase.
7. Switch power to the Control Unit off and then back on.

Within the terminal program you should see various messages as the Control Unit performs various start up tasks.

8. Close the terminal program session.
9. You can now use Manager to alter and then upload an old
configuration file or receive and edit the Control Unit's now defaulted configuration.

Erasing the Operational Software
Do not perform this process unless absolutely necessary. If you want to upgrade the software this can also be done via the Upgrade tool in the Manager application (File | Advanced | Upgrade).
THIS PROCESS ERASES THE OPERATIONAL SOFTWARE and system
configuration. Before attempting this process you MUST know the MAC and IP addresses of the system, plus have a backup copy of its configuration and the correct .bin file for the Control Unit type and level of software.


1. Run Manager. In the BOOTP entries check that there is an entry that matches the MAC Address, IP Address and .bin file used by the system (the first two details can be found in the Unit settings in the system's configuration file).
2. If an entry isn't present, create a new entry. Then close and restart Manager.
3. Under File | Preferences ensure that Manager is set to
255.255.255.255.
4. Select View | TFTPLog.
5. Check that the required .bin file is present in Manager's working directory.
6. Attach the serial cable between the PC and the DTE port on the IP Office Control Unit.
7. Start the terminal program on your PC. Ensure that it has been setup as listed in "DTE Port Settings".
8. Arrange the program windows so that the Terminal program and Manager TFTP Log are visible at the same time.
9. Switch off power to the IP Office Control Unit.
10. Power on the Control Unit and press the escape key every second until you get a Loader message.
11. Enter AT (note upper case). The Control Unit should respond OK.
12. Enter AT-X. The Control Unit should respond Multi-Sector Erase.
13. The Control Unit will now request the .bin file it requires from Manager. This process appears in the TFTPLog.
14. When completed the system will reboot.
Below is an example of the TFTPLog of a successful transfer.
: Received BOOTP request for 00e007000123 192.168.42.1 napremis.bin
: Sending BOOTP response for 00e007000123 192.168.42.1 napremis.bin
: Sending napremis.bin length 654321 bytes to 192.168.42.1
: Sent 10% of napremis.bin
: Sent 20% of napremis.bin
: Sent 30% of napremis.bin
: Sent 40% of napremis.bin
: Sent 50% of napremis.bin
: Sent 60% of napremis.bin
: Sent 70% of napremis.bin
: Sent 80% of napremis.bin
: Sent 90% of napremis.bin
: Sent 100% of napremis.bin
: Sent napremis.bin length 654321 bytes

The following in the TFTPLog indicates that the required .bin file is not in ManagerÆs Working Directory. A set of .bin files is available on the IP Office Administration Applications CD in the \bin folder.
: Received BOOTP request for 00e007000123 192.168.42.1 napremis.bin
: Sending BOOTP response for 00e007000123 192.168.42.1 napremis.bin
: Unable to send napremis.bin length 0 bytes

The following in the TFTPLog indicates that a matching BOOTP entry was not found. If this occurs use Manager to add or edit the required BOOTP entry.
: Received BOOTP request for 00e007000123 192.168.42.1 napremis.bin, unable to process.
