Fig. 64 Module Properties

Identification

Table 13 Identification

Property

Explanation

Module Name

The Xena test module model type.

Module Revision

The Xena test module model type plus revision information if relevent.

Module Description

A user defined description of the Xena test module.

Serial Number

The Xena test module serial number.

Version Number

The currently loaded firmware version number.

Firmware

This button allows you to manually upgrade this module with a firmware image that has been uploaded using the controls in the chassis panel. Usually, it is recommended that you use the firmware upgrade functions in the ChassisUpgrader program as this provides a more automated and user-friendly approach.

Port Count

The number of detected ports on the module.

Status

Table 14 Status

Property

Explanation

Module Temperature

The current module temperature in degrees (Celsius).

Reservation

Table 15 Reservation

Property

Explanation

Reserved By

If the module is currently reserved by someone this field contains the username of the reserver.

Timing Configuration

Table 16 Timing configuration

Property

Explanation

Timing Source

Control how the test module time-stamp clock is running, either freely in the chassis, on the module itself or locked to external system time (requires the TimeSynch option). Running with free chassis ore module time allows nano-second precision measurements of latencies, but only when the transmitting and receiving ports are in the same chassis or on the same module. Running with locked external time enables inter-chassis latency measurements, but can introduce small time-discontinuities as the test module time is adjusted.

Local Clock Adjustment

Makes a small adjustment to the local clock of the test module, which drives the TX rate of the test ports. The property value is the desired adjustment from the nominal value, in parts-per-billion, positive or negative.

SMA Output Function

For test modules with SMA connectors, this property selects the function of the SMA output.

SMA Input Function

For test modules with SMA connectors, this property selects the function of the SMA input.

TX Clock Source

For test modules with advanced timing features, this property selects what drives the port TX rates.

TX and SMA Clock Filter

For test modules with advanced timing features, this property determines the loop bandwidth on the TX clock filter.

Clock Sweep

Note

Clock sweep function is not available across all modules.

Clock offset sweep provides the ability to let the system make controlled clock variations on all ports on a module. The function works together with the Timing configuration function.

Fig. 65 Clock sweep

Clock Offset Sweep

Sweep will be done as a symmetrical increase and decrease in ppm starting from the configured Local clock Adjustment

Table 17 Clock offset sweep

Property

Explanation

Sweep mode

Determines if the sweep is done as a Linear or Step sweep. Step size and duration is calculated based on maximum offset and sweep iteration duration.

Sweep direction

Determines if the sweep should start with an increase or decrease in ppm

Iterations

Determines if the system performs a fixed number of iterations before stopping, or infinite iterations. Setting the parameter to 0, will make infinite sweeps until stopped by the user

Maximum Offset

Determines the maximum ppm offset value possible. The value can be configured until ppm offset reaches the limit of Maximum supported offset deducted the numerical value of the Local clock adjustment.

Slope

Configures ppm/s. Adjusting slope will affect the sweep iteration duration.

Note

Max Sweep duration is 64 secs. It is not possible to start sweep unless Max Sweep duration is 64 sec or less

Clock Offset Waveform

Clock offset waveform shown in Fig. 65 illustrates the configured sweep configuration with the parameters listed above.

Clock Sweep Control

Table 18 Clock sweep control

Property

Explanation

Sweep iteration duration

Shows the duration (in seconds) of an iteration for the configured ppm sweep

Sweep iteration

Shows the number of iterations done of the configured ppm sweep

Current sweep progress

Shows the progress (in %) of the current iteration for the configured ppm sweep

Current clock offset

Indicates the value of the current clock offset (in ppm).

Sweep control

Start and stop ppm sweep

Note

PPM sweep can be done both with and without active traffic on the ports on the module.

Media Configuration

Table 19 CFP Configuration

Property

Explanation

CFP Type

Describes the type of CFP. The following values are supported

  • Not a CFP: This is not a CFP-based test module.

  • CFP (Not Present): No transceiver, the CFP cage is empty.

  • CFP (Not Flexible): Transceiver present, supporting a fixed speed and port-count.

  • CFP (Flexible): Transceiver present, supporting flexible speed and port-count.

If CFP type is Not a CFP configuration and speed settings cannot be changed at module level. It may be possible to change speed at port level. For the other values it is possible to change Media Configuration i.e. which cage(s) are used on the module and if relevant in what configuration. It may also be possible to change Port Configuration i.e. number of ports and port speed.

Media Configuration

This property specifies which cage(s) are used on the module and if relevant in what configuration

Port Configuration

If enabled this property specifies number of ports and port speed on the module

CFP Configuration

This property was used in older versions of XenaManager/XenaManager. This property shows the current number of ports and their speed of a CFP test module. For a flexible CFP type, it also allows the user to change the configuration.

Note

This property is not supported for non-CFP modules.
