The only cards you’ll need is something to connect up a digital phone to, so either a 4DM or a 2DM card in the middle slot to connect up a phone.
To set the system into UK mode, your DIP switches must be set to
01000000. For other country codes, look into the documentation.
I’m using an old IDE CD-ROM drive audio cable to serial that I’ve created for this purpose. As there aren’t 3 contiguous pins, I used both ends of the cable to give me 2 + 1 for the 3 pins.
The serial port on the PBX is the 3 pins behind the line card slot at the bottom of the system. I’m using a StarTech USB Serial adapter on Windows 10 and it’s functions perfectly.

All you want to alter in this is the Current Directory so that it offers all your firmware and bootrom files. The Server interface should be your computers local IP address and TFTP security should be set to None.
Fire up the system with your serial cable connected and you should see the system booting up. You’ll need to press the Q key to interrupt the boot process.
If you’re replacing en existing cabinet, you can change the current system’s MAC address to match the old system ensuring you can use the same licences. For example:
setenv eth1addr 00:16:32:82:9c:8b ; setenv ethaddr 00:16:32:82:9c:8b ; saveenv
Once you’ve booted up, enter
printenv to check current boot variables. If your
bootfile variable is lower than
v493 you will need to upgrade this via:
setenv bootfile bt30v493.bin ; setenv ipaddr 10.0.0.247 ; setenv gatewayip 10.0.0.1 ; setenv serverip 10.0.0.66 ; setenv netmask 255.255.255.0 ; saveenv ; run updateboot; run clearenv ; reset
The important values to look at here are
ipaddr which is your OfficeServ system’s IP address, and
serverip which is your TFTPD server address. By default, the system’s IP address is 10.0.2.10 and the gateway address is 10.0.2.1, but you’ll likely want to change these.
Once you’re on bootrom v4.93 you can upgrade the rest of the system using:
setenv ipaddr 10.0.0.247 ; setenv gatewayip 10.0.0.1 ; setenv serverip 10.0.0.66 ; setenv netmask 255.0.0.0 ; setenv mspname ms30v125.pkm ; setenv cspname cs30v493.pkm ; setenv rfsname rd30v501.pkm ; saveenv ; run nanderaseall ; run install
This process will take a long time to complete, but you’ll be given the status of the upgrade via your serial connection.
Once booted up, verify your firmware version via:
Trans 800 4321 1 Speaker 727, this should be 5.01. Log out with
Trans 800 0 Trans and connect up using OSDM.
The address will be whatever you set the
ipaddr variable to in the preceeding steps. The default password for firmware v5.01 is
#PBX1357sec.com. It will ask you to change this when you first login.
Once logged in, if you have existing licences, add them via MMC860.
Lastly, as we’ve entirely wiped this system during the upgrade process you’ll need to upload your voicemail prompt package, usually called
VM_L_UK.tgz. This can be done via:
File Control > Program > File > VM_L_UK.tgz > Upload
After the file has been uploaded, reboot the system in MMC811. Once the system is back up and working, dial the VM group (usually 509) to ensure your prompts are all working. Enjoy your new system.
