Connecting power to the unit

The IPS-AC1 from Zenitel is a 48VDC power supply, with input voltage range 85-264 VAC. It is designed for DIN-Rail mounting.

The Power Supply IPS-AC1 (Item no: 1002510000)

As an option one can use a locally provided power supply unit (PSU). The gateway must be powered by 24VDC or 48VDC. Recommended power rating of the PSU is minimum 24W (24V/1A or 48V/0.5A).

OBS icon In order to comply with UL safety requirements, the gateway has to be supplied by a power supply specified as a Limited Power Source (LPS) or PS2 (cased on IEC/UL 62368-1 definition) or NEC Class 2 source of supply. The IPS-AC1 meets this criterion.

The connector is a WAGO 734-203/037-000.


The gateway has two RJ-45 ethernet ports for IP communication. Ethernet port 0 (Eth 0) is by default configured as a Management port, allowing connection to the embedded web server (ICX Web) and connection of the PC configuration tool AlphaPro. Default IP addresses:

  • Eth0: Static IP address
  • Eth1: Obtains IP address automatically (DHCP)

Start up and initial configuration

  1. Power up the gateway
  2. Watch the LEDs. During startup the Power LED and the Fault LED will be lit. The system uses approx. 20 seconds to start up. When up and running, the green status LED will start flashing.
  3. The unit comes with an embedded web server (ICX Web), which provides functions for system configuration, monitoring and upgrade. Initial connection is done by connecting a laptop to Eth port 0, open a web browser (e.g. Firefox or Chrome), and log on to the web server using IP address (Default Username/Password = admin/alphaadmin).
  4. Upgrade the software of the unit to the latest version. Upgrade is done from the web interface of the gateway. This will ensure that the system has the latest features, bug fixes and security updates.

Status LEDs

The gateway has a number of status LEDs. The same LEDs are located both in front and at the rear side of the unit.

LED Description
Power Steady green when power is applied
Status Flashing green when the unit is running
Fault Steady amber when the system reports an error. The LED will be lit during application or system reset, or if there is a temperature alarm.
Active Steady blue when the gateway is operational.
In a system with redundant servers, the Active LED will be lit on the operational gateway, and not lit on the standby gateway
Link Steady green when the ethernet link 0 or 1 is up. There is one LED for each ethernet port
RX/TX Flashing when receiving or transmitting data on ethernet port 0 or 1.

Fault Relay

The fault relay will trigger when the system reports an error. In normal operation the relay is energized, which means it will also trigger on power outage.

Fault is reported:

  • During Application or System reset
  • If there is a Temperature alarm (Thresholds are 75C on PCB, 95C on CPU)
  • If Power failure

User configuration

  • AlphaPro is the Windows application used for configuration of the gateway. Configuration of user data, such as Directory Numbers, Direct Access Keys, Group Calls etc. is done from AlphaPro.
Note icon The gateway requires configuration tool AlphaPro ver. 12 or higher

Factory Reset (cold boot)

The factory reset button is used to restore the unit to factory settings. The factory reset (cold boot) button is located on rear side, behind the same protection lid as the micro SD card.

Two different procedures are available:


  • Load default intercom database
  • Reset all IP settings to default (E.g. IP addresses and Filters). Eth0 will get IP address, subnet mask
  1. Press an hold the "Factory Default" button
  2. Power up the unit while the button is pressed
  3. Keep the button pressed for approx. 5 sec., then release it
Note icon
  • This procedure will clear all settings done from the web interface
  • The procedure will also delete the License file, Log files, Audio Messages (wav files), Audio Language Packages and Backup files

Intercom Configuration only:

  • Keep the IP settings
  • Load default intercom database
  1. Power up the unit
  2. Wait for 5 sec., then press and hold the “Factory Default” button
  3. Keep the button pressed until the Status LED is flashing green or the fault relay is clicking (Approx. 10 sec)

Factory reset can also be done from the ICX web interface: System Maintenance > System Recovery > Load Factory Defaults

Software upgrade

  • It is highly recommended to Upgrade the software of the gateway to the latest version. Upgrade is done from the web interface of the gateway. This will ensure that the system has the latest features, bug fixes and security updates.

Accessing the SD Card and Factory Default button

The SD Card and the Factory Default button are located behind a protective lid.

Opening the lid to access SD card and the factory default button
  1. Locate the lid, it is between the fault relay and the power connector
  2. Loosen the screw, but don't remove. Tool: Torx T6.
  3. Lift the lid out at the bottom side (Picture 1)
  4. Remove the lid (Picture 2)
  5. The SD card slot and factory default button are now accessible
  6. Replace the lid in reverse order

Dimensions & Mounting



Wall/Shelf Mounting

Using the IA-MB1 mounting bracket (item no: 1002500020), the unit can be mounted on any flat surface such as a wall or shelf. The following procedure is for a mounting on a wall as an example.

1. Mount the bracket to the wall using the 3 screws provided.

To have logo and connection annotations in the correct viewing orientation, you may slide the unit top or bottom down into the bracket depending on whether it is mounted on a wall, desk or shelf.

Rack Mounting

Using the IA-RS1 Rack Shelf (item no: 1002500010), two units can be mounted side by side in a 19" 1HU rack.

1. Slide the 4 mounting clips into the side walls of the rack shelf.

3. Use the 2 countersunk type M4x8 screws to secure the unit to the rack shelf via the 2 diagonally positioned securing holes.

The securing holes can also be used to mount the unit to a shelf other than the IA-RS1. Note that the maximum insertion depth is 6 mm.
