Verify operation of the new DEMPR (Rev. "C1" or higher) via offline power-up and self-test diagnostics. Follow steps outlined in section 4.3 of the DEMPR Installation and Users Guide (EK-DEMPR-UG-001). 2. Perform all the procedures and customer notifications necessary to allow removal and replacement of the DEMPR from the Network Configuration. 3. Remove power from the original DEMPR that is to be replaced by disconnecting the AC power cord from the unit. ******************************************************************************** * *** CAUTION *** * * To assure that the AC power is removed from the unit, the AC power cord * * must be disconnected. * ******************************************************************************** 4. Disconnect all Thinwire and Transceiver cable connectors from the original DEMPR. 5. Remove the original DEMPR and replace with new DEMPR (rev "C1" or higher) supplied in this EQ Kit. 6. Reconnect all cabling, in the original configuration, onto the new DEMPR. 7. Connect the power cord to the new DEMPR. 8. Monitor the new DEMPR's power-up and initiate self-test diagnostics to verify the unit. Follow steps 1-13 section 4.3 of EK-DEMPR-UG-001. 9. Place the new DEMPR into full network service upon successful self- diagnostics. 10. Verify that the network is operating properly. 11. Replace the original (TIRS) DEMPR Installation/Users Guide (EK-DEMPR-IN) with the new DEMPR Installation/Users Guide (EK-DEMPR-UG-001). NOTE: EK-DEMPR-IN (DEMPR Installation and Users Guide) is only for Revision "B1" DEMPRs and CANNOT be used for the installation and testing of Revision "C1" DEMPRs'. ONLY EK-DEMPR-UG can be used for Revision "C1" and later DEMPRs. EK-DEMPR-IN should be removed from the site and properly disposed of to avoid any confusion. 12. Update the Site Management Guide to reflect the installation of this FCO. 13. Complete LARS as per attachment and return out of Revision TIRS DEMPR to the repair facility for rework/upgrade. _ _ _ _ _ _ _ | FCO DEMPR-R001 | | | | | | | | | |d|i|g|i|t|a|l| | PAGE 3 OF 10 |_|_|_|_|_|_|_| | | _______________________________|_________________________________________ NOTES: 1. When the Revision "B1" DEMPR is replaced with a Revision "C1" or higher DEMPR, the LAN Bridge 100 is not needed to protect the network. 2. If this site participated in the TIRS program, after this FCO has been completed, the program at this site has ended. The DEMPR, DESTA (Station Adapter) and DEBET (LAN Bridge 100) are eligible for Service Contracts if the normal Warranty period has expired. ADDITIONAL INFORMATION:: TIRS RECONFIGURATION INFORMATION ******************************************************************************* * ANY RE-CONFIGURATION OF THE NETWORK IS NOT PART OF THIS FCO!!! * * THE FOLLOWING CONFIGURATION DIAGRAMS HAVE BEEN INCLUDED * * FOR YOUR INFORMATION ONLY!!! * ******************************************************************************* CONFIGURATION DIAGRAMS For Revision "B1" and the earlier prototype DEMPRs', only the configurations found in the DEMPR Installation and Users Guide Addendum (EK-DEMPR-IN) were supported. For these Revisions of DEMPR, configuration guidelines found in the DECCONNECT Documentation WERE superseded by the addendum information. When FCO (DEMPR-R001) is implemented, these configurations are no longer required. The following information explains how the earlier configurations can be re-configured to a normal configuration. NOTES: 1. Replacing a Revision "B1" DEMPR with a Revision "C1" or higher DEMPR does NOT require reconfiguration. 2. The Installation and Users Guides for the Revision "B1" DEMPR and the Revision "C1" DEMPR are not compatible. Use EK-DEMPR-UG for the installation and testing of "C1" DEMPRs'. 3. Any re-configurations should be charged for in the same manner as any other de-installation/re-installation. Re-configurations are not a part of this FCO (DEMPR-R001). De-installation = 1 x BMC (FOR EACH OPTION) Re-installation = 2 x BMC (FOR EACH OPTION) 4. Plan and prepare for any re-configurations. Re-configuration may require additional transceiver cables, re-routing of cables, an H4000-BA transceiver and relocating hardware. _ _ _ _ _ _ _ | FCO DEMPR-R001 | | | | | | | | | |d|i|g|i|t|a|l| | PAGE 4 OF 10 |_|_|_|_|_|_|_| | | _______________________________|_________________________________________ The following shows the Revision "B1" configuration, which is referred to as TIRS Configurations #1, #2, and #3, with its standard configuration for Revision "C1" DEMPRs'.
