    A user assigned only Network User rights will not see the Restore option in the System Configuration menu. A System Restore can only occur if a previous system configuration has been backed up as described in "SeRF II Module Replacement Part 1: Backup the Current System Configuration” on page You typically perform a System Restore on a system that is running the same EMS software release that was active when the backup file was created. That is, if the system backup occurred on an 8.1.5.6 system, and the system is now running 9.0, Restore will not function as expected. ® FWPP-514-02 FlexWave Host Unit and Host Expansion Unit Module Replacement Guide © October 2017 CommScope, Inc.

    • Unit returns with all Remote Units discovered and the System Busy message (System is busy … Please wait.) has stopped being displayed before starting a System Restore on the next Host Unit. In a Multi-Host system, any Host Unit can perform a backup and restore on its system, which includes the • Remote Units that are connected to it. General configurations are restored completely. RF configurations are restored for those RF Modules that belong to the Host Unit performing the restore. Since each Host Unit is free to do its own general configuration it is also free to restore the Remote Unit RF Module to previous settings. Since the admin can clear the configuration of all connected Remote DARTs (or the entire Remote Unit itself), this user can also restore the system back to any setting, such as taking a Remote Unit out of a Multi-Host setup and place it under the management of a single Host Unit. This can be achieved in the following two-step process: Clear the Remote Unit configurations for the RF Modules not previously owned by this Host Unit. Restore the Remote Unit configurations to a previous configuration when the Host Unit owned all the Remote Unit RF modules. ® FlexWave Host Unit and Host Expansion Unit Module Replacement Guide FWPP-514-02 Page 18 © October 2017 CommScope, Inc.

To clear System Test Required alarms, you must run System Test; follow the procedure in “Running a System Test” in the FlexWave Software Release 9.0 System Setup and Provisioning Guide. Follow the steps in "Check for Alarms” on page 48 to verify that no additional or unexpected alarms have occurred as a result of this CF card replacement. 46 Notify the NOC or alarm monitoring system operator that the new SeRF II Module is in place and the Host is back online. ® FWPP-514-02 FlexWave Host Unit and Host Expansion Unit Module Replacement Guide © October 2017 CommScope, Inc.

    EMS Frame View in the EMS Frame View S IN THE The following sections provide information on working with HEUs in the FlexWave EMS. Identifying an HEU in the System Tree In the System Tree, an HEU is identified as a DRU. Since a DRU is only found in a Spectrum system, within a FlexWave Prism system, a DRU icon can only indicate the presence of a Prism Host Expansion Unit (HEU). ® FlexWave Host Unit and Host Expansion Unit Module Replacement Guide FWPP-514-02 Page 46 © October 2017 CommScope, Inc.

  • Page 54: Identifying Alarms That Correspond To An Heu

    Identifying Alarms that Correspond to an HEU With the exceptions noted below, generic alarms that correspond to Remote Units also apply to the HEU. The Temperature High alarm for Remote Units is generated when the ambient temperature for an HEU SeRF • Module goes over 50°C. The DRU Temperature Low alarm is generated when the ambient temperature for an HEU SeRF Module goes • below -5°C. HEUs do not support the Uplink Inactivity Fault. • HEUs do not have LPAs, LNAs and PDs. Consequently, there will be no Remote Unit alarms related to Linear • Power Amplifier (LPA), LNA and PD modules for HEUs. For further information on alarms, refer to the FlexWave Prism and Spectrum Element Management System Alarm Reference. ® FlexWave Host Unit and Host Expansion Unit Module Replacement Guide FWPP-514-02 Page 50 © October 2017 CommScope, Inc.

In addition to the color codes described in "Alarm Color Codes” on page 224, the View Status page for Host Units also uses a gray background and an uppercase D to indicate that an alarm has been disabled (see "Enable and Disable Alarms” on page 239). Should a fault or alarm be active in the View Status page, do the following to find out more information about that alarm. In the System Menu bar, click Alarms > View Current Alarms to open the View Current Alarms page. Click on the row that lists that same alarm in the View Current Alarms page.

The fault threshold cannot be changed, and is – -18 dBm for IR – -27 dBm for LR. • Module Missing Fault—one of the Host Unit SFPs is missing. Note that the Module Missing Fault only activates if there is an active link on that SFP. (If you pull an SFP from the Host Unit that has not been linked, the EMS does not activate a Module Missing Fault, it just removes the SFP from its database. ® FWPP-514-02 FlexWave Host Unit and Host Expansion Unit Module Replacement Guide © October 2017 CommScope, Inc.

    Conflict alarm is a transient alarm; it will be cleared within 30 seconds, as the EMS automatically changes the Clock Priority Level on one or both of the Host Units so that the two Host Units have different clock priority values. If it is intended that a specific Host Unit should provide the master clock, the new priority values should be checked and adjusted manually if necessary (see "Set the System Reference Clock and Clock Priority” on page 54). Clock Configuration Invalid—the system is currently configured to use the internal 10 MHz clock reference, • but the CDIU requires an external reference, resulting in no RF for the CDIU bands. Temperature Table for Host Units The Temperature table gives the current temperature of the Host Unit chassis interior (as detected by the Host Unit) in degrees Centigrade and Fahrenheit. ® FlexWave Host Unit and Host Expansion Unit Module Replacement Guide FWPP-514-02 Page 54 © October 2017 CommScope, Inc.
