10.9 System Views

The System Views section provides collated Status/Configuration Information related to the DAS.

10.9.1 System Snapshot

This section provides the view of the entire system configuration and status information for the DAS in

a tabular form. The user can save the view as an HTML file that can be displayed by any supported

browser.

10.9.2 Alarm Counts

This View lists all units/modules for which the count of any alarms is non-zero (the Alarm Count is a

cumulative number for all the instances of an alarm since the last system restart).

10.9.3 Link Quality

This is a single page View of the fiber optic link quality for the DAS. Uplink and Downlink paths are

shown for all optical links in the system. Measured optical losses are displayed. If the RF Calibration

function on the System Maintenance page has been executed, then applied RF calibration values are

also displayed.

10.9.4 RU DC Power

This is a single page View showing the DC power parameters for all Remote Units in the DAS. The

table reports the input voltage, input current and power dissipation measured by each RU. The power

dissipation of each DC supply cable is also calculated if the SH or RM-PSU voltage is available for that

particular RU. PSU Port Association is displayed, an output from performing the RF System Check. It

maps the power ports on the Secondary Hubs with the Remote Units they are connected to.

10.9.5 RU Calculations

This single page View displays the applied RF settings and calculated gain for all the Remote Units in

the DAS, from each Service Module input that has been enabled. It is updated by clicking Validate

Settings and Apply Settings on the System Setup page.

10.9.6 RF System Check

This view displays a number of RF parameters for each Remote Unit in the system :- the health of the

Power Amplifier in the Remote Units (PA Health); background noise level (Background Level); isolation

between Tx and Rx antennas for each Remote Unit (Tx/Rx Antenna Isolation); and cross-coupling

(Cross-Coupling Tx/Rx) between the transmitting Remote Unit and receiving ports of the other Remote

Units in the system. Note that strong background RF signals can potentially cause false readings with

the cross-coupling test.
