2. Setup
The OpenStage 30 T is a digital system phone that requires connection to a compatible Unify (formerly Siemens Enterprise Communications) PBX system. It is not designed for direct connection to a standard analog telephone line.
2.1 Connecting the Phone
- Connect the Handset: Plug the coiled cord from the handset into the designated port on the side or back of the phone base.
- Connect the Line Cord: Connect one end of the telephone line cord to the 'Line' port on the back of the OpenStage 30 T phone. Connect the other end to the appropriate digital extension port on your PBX system or wall jack provided by your system administrator.
- Power Connection: The OpenStage 30 T typically receives power directly from the digital line connection to the PBX. No separate power adapter is usually required. If your specific setup requires an external power supply (not included), connect it to the designated power port and then to an electrical outlet.
2.2 Initial Boot-up
Once connected, the phone will power on automatically. The display will show a boot-up sequence, and then typically display the date, time, and your extension number. If the phone does not power on or displays an error, consult the Troubleshooting section or your system administrator.
