1.205 ETL-NGM100-Matrix

This page describes the device driver and the device window for ETL L-Band Switch Matrix NGM-100 series.

The driver works with the distributive matrix only. It supports 32x32 and 64x32 models.

Device window pages

The following table shows which device window pages are available with this individual device type. Tool-bar functions not mentioned here are described at the general description of device windows .

• --- Port switching by name 1-32.
• --- Port switching by name 33-64.
• --- Port switching by number 1-32.
• --- Port switching by number 33-64.
• --- Edit input names.
• --- Edit output names.
• --- Redundancy settings.
• --- External input fault configuration.
• --- The faults page.
• --- The device info page.
• --- The maintenance page.

Configuration parameters

At the maintenance page of the device window there are a couple of configuration parameters which must be set to make the software talk to the device as well as the hot/cold standby settings per module.

• address --- The SNMP address specification for the device. The full address specification consists of the following fields: aaa.bbb.ccc.ddd:pppp read-community write-community
  • aaa.bbb.ccc.ddd --- The IP address of the device in 'dotted quad' notation. This field is mandatory.
  • pppp --- The IP port number where the device accepts SNMP requests. The port number may be omitted, the driver uses the standard port 161 in this case.
  • read-community --- The SNMP read community name. This must match the read community expected by the device.
  • write-community --- The SNMP write community name. This must match the write community expected by the device. The write community name may be omitted, the driver uses the read community name for both, read and write in this case. If both community names are missing, the driver uses 'public' as a default for read and write community.
• readBackDelay --- Defines the delay the driver uses when it reads back parameters recently commanded. The delay is initialized at a proved preset value which should not be changed under normal circumstances.

Alias names

After changing the alias names of the input and or output channels from the device driver or Web interface it is necessary to use the READ ALIAS NAMES FROM CHASSIS button on the device driver. The reason is that reading these value is only done initially at the server startup due to the slow device SNMP performance.

External Input Faults

When checking the configtion for a input card redundancy switching, the driver not only checks the input card faults, but also an user configurable external fault for every matrix input. This external fault for instance may monitor the health of an fibre optics receiver in front of the matrix input. The IDs for these externals faults are configured at a separate page of the device screen. Please note, that because the IDs are considered as configuration parameters, a privilege level of 150 is required to change these.
