This articles shows possible solutions for redundancy with the ICX-AlphaCom server.

ICX-AlphaCom redundancy

For redundancy between ICX-AlphaCom servers, see Redundant Servers (High Availability).

High availability and fault tolerant solution maximizing uptime during
- System level failures
- Environment-level failures (power outage, fire, earthquake, etc.)
- Planned outage for system maintenance and upgrades
Maximum downtime at switch-over (552 stations) is 35 seconds

Redundant ICX-AlphaCom system

Power Supply redundancy

The ICX-AlphaCom normally has one power supply, and it only supports one power input. Using third party products it is possible to Increase durability by adding a solution for redundant power.

Such a full redundant system might look like this:

Principal sketch for redundancy system

An example Power Supply configuration with optional TKIS-2 to provide Power Supply and ICX-500 monitoring:

Redundant Power Supply solution using Phoenix Contact products

RCO or RCI

Any physical inputs and/or outputs needs to communicate with the server via an IP device such as the TKIS-2 or an IP-LCM. These devices, as any other IP device in a redundant system must register and communicate with the operational IP address, and thus always be online with the active server.

Serial Port

The ICX-AlphaCom does not have a serial port and must use an Ethernet-to-serial converter. Since the ICX-AlphaCom redundancy system is using a singular IP address as the operational IP address the solution is to have the converter pointed at the operational IP address, and will work fine, independent on which server is the active one.

Monitoring redundancy in VS Operator

The VS Operator can be used together with a redundant system, communicating with the Operational IP address.

VS-Operator can provide graphical indications of Server Status and Server Operational Mode. It can also display the Power Supply status.

Monitoring Servers

Here is a description on how to set up monitoring so the ICX-AlphaCom statuses can be viewed in VSOP.

An example of the VS-Operator display:

Redundancy monitoring

AlphaPro Events

To pass the Server Status and Operational Mode to VS-Operator, we use a Dummy Number (9600) and the Custom Parameter feature. We also add an event to trigger a refresh of the status' towards VSOP using another dummy number (991)

In AlphaPro configure these two events:

Redundancy monitoring event

Action commands:

IF %op(%udd(101),=,1)
@*D1 M7F01 L(1)9600 U0 W1 W2 W0 W0 W0
ENDIF
IF %op(%udd(101),=,2)

ENDIF
IF %op(%udd(101),=,4)
@*D1 M7F01 L(1)9600 U0 W3 W1 W0 W0 W0
ENDIF

Timeout event

Action commands:

$ST L%1.dir W200 L991
IF %chg(1,0)
IF %op(%syse(230),==,0)
IF %syse(232)
WUDD 101 1
STOP
ENDIF
WUDD 101 2
STOP
ENDIF
ENDIF
IF %syse(232)
WUDD 101 3
STOP
ENDIF
WUDD 101 4

VS-Operator configuration

Create two icon sets to display the status. One icon set will be for the Operational Status of the ICX-AlphaCom, and the other will be to indicate the VS-Operator connection to the Operational Server.

The icons used in this example are created in PowerPoint.

Operational Status Icons

Navigate to the Icon sets menu and click Add, then choose GPD:

Give the GPD Icons a name, in this case IPHA_Monitor

Add your four custom icons as GPD state 0-3 by clicking the 3 dots beside 'Image', selecting the Load button and navigating to your Icon. Note that after loading, you may need to disable the Stretch option to display correctly.

State 0 - Blank Icon
State 1 - Operational Icon
State 2 - Standby Icon
State 3 - Offline Icon

dd icons to GPD StatesA C

System Operation Icons

Navigate to the Icon sets menu and click Add, then choose Node:

Adding Node Icon Set

Add your two custom icons as Node state 0-1 following the directions in the last step.

Adding custom icons

VSOP Map

To display the Icons, we need to create a Map page with a background. In the example below, the Zenitel logo and the icons for the ICX Primary and ICX Secondary has been created as a static image in Powerpoint.

Click on Map Pages, followed by Add. Give the map a name and load in the background image. Resize accordingly.

dding a Map pageA

VSOP Startup script

If VSOP is started after the IPHA monitor scripts have already run in the ICX-AlphaCom Event Handler, the status of the Operational Server or System status unknown, so a startup script is needed the force the Event Handler to resend the status. Here, we send a command to the ICX-AlphaCom to start a 10 second timer on our Dummy Number 991

Click on Menu and Global Settings. Enable the Startup script and click on the 3 dots to open the editor. Add the following line;

App.STE ("$ST L101 W100 L991");

Adding a Startup Script

VSOP Filter

In order to catch the custom parameters sent from the Event Handler we need a filter, and this filter must be tied to our first Dummy Number 9600.

Click on Filter Sets, followed by Add and Station.

dding a Filter SetA

Create a custom filter using the On Custom Params message

Give the Filter a name, here we are using IPHA_State. Select On Custom Params and enable the check boxes for Show, Log and Script. Enter a Message Text to be displayed in the Journal and enter the Script.

int n1 = App.Params.Get("cp1", 0);

int n2 = App.Params.Get("cp2", 0);

App.SetGPDState("Primary", n1, true, true);

App.SetGPDState("Secondary", n2, true, true);

Press the Test button, followed by the OK button.

Adding the Filter Script for On Custom Params

Adding devices to VSOP

Add two GPD devices. Name these 2 devices Primary and Secondary. Set the Source name field for Primary and Secondary respectively. Set the Icon Set for IPHA_Monitor.

Add one Node Device. Name this the Node name of the system. Set the Icon Set for NodeStatus

Add one Station device. Name this IP_HAFilter and set the AlphaCom Station to Node 1 Directory Number 9600 and the Filter Set to IPHA_state.

Place the icons on the map by drag and drop.

Redundant Power supplies

The Power Supplies can be monitored, and faults and warnings can be logged.

Here is a description on how to set up monitoring so the redundant power supply statuses can be viewed in VSOP.

Redundant power monitoring

The following description relates to the redundant power solution as mentioned further up in this article

AlphaPro Event

In AlphaPro configure the two TKIS-2 kits which receive the inputs from the Redundancy module as 9901 Primary and 9902 Secondary. Put them both in a UDP group (UDP2 is used in this example), and create this event:

Redundant power supply monitoring event

Action commands:

@*d1 M7F03 L(1)9901 U0 W%chg(1,0) W%sev(1) W0 W0 W0 "PSU%1.nam\t %1.nam\t"
IF %chg(1,0)
IF %op(%sev(1),=,1)
LOG "Power redundancy DOWN for %1.nam server"
STOP
ENDIF
IF %op(%sev(1),=,2)
LOG "Power redundancy WARNING for %1.nam server"
STOP
ENDIF
ENDIF
LOG "Power redundancy OK for %1.nam server"

VSOP Icons

Create a icon set (the icons used in this example is created in PowerPoint): The GPD Icons used for the Redundant Power Supply statuses:

Navigate to the Iconsets menu and click Add, then choose GPD:

Adding GPD icon set

Add your four custom icons as GPD state 0-3:

Creating custom GPD icon set

VSOP Filter

In order to catch the custom parameters sent from the Event Handler we need a filter, and this filter must be tied to an Intercom station.

1: Adding Station filter set

Create a custom filter:

Creating custom filter set

int RED_state = App.Params.Get("cp1", 0);
int RED_type = App.Params.Get("cp2", 0);
if (RED_state==1)
{
App.SetGPDState("%CSP1", RED_type, true, true);
if (RED_type==1)
App.Log("Redundancy power for %CSP2 server is reported down", true, true);
else if (RED_type==2)
App.Log("Redundancy power for %CSP2 server reports a warning", true, true);
}
if (RED_state==0)
{
App.SetGPDState("%CSP1", 3, true, true);
App.Log("Redundancy power for %CSP2server is reported OK", true, true);
}

%CSP1 (custom string parameter 1) refers to the name of the GPD's as set here:

GPD name reference

Adding devices to VSOP

Add two GPD devices and one Station device.

Right click the GPD devices and select the GPD custom Icon Set made for Redundant Power Supply monitoring
Right click the TKIS-2 station (dir no 9901) and select the station custom filter for Redundant Power Supply monitoring

Place the icons on the map by drag and drop.
