Download the BTS 68P09258A31–A Download the BTS Overview Before a BTS can operate, each equipped device must contain device initialization (ROM) code. ROM code is loaded in all devices during manufacture or factory repair, or, for software upgrades, from the CBSC using the DownLoad Manager (DLM). Device application (RAM) code and data must be downloaded to each equipped device by the user before the BTS can be made fully functional for the site where it is installed.
Download the BTS 68P09258A31–A When code is downloaded to an MGLI or GLI, the LMF automatically also downloads data and then enables the MGLI. When enabled, the MGLI will change to INS_ACT (bright green). A redundant GLI will not be automatically enabled and will remain OOS_RAM (yellow). When the redundant GLI is manually commanded to enable through the LMF, it will change state to INS_SBY (olive green). For non–MGLI devices, data must be downloaded after RAM code is downloaded.
Download the BTS 68P09258A31–A Verify GLI ROM Code Loads Devices should not be loaded with a RAM code version which is not compatible with the ROM code with which they are loaded. Before downloading RAM code and data to the processor cards, follow the procedure in Table 3-12 to verify the GLI devices are loaded with the correct ROM code for the software release used by the BSS.
Download the BTS 68P09258A31–A Download RAM Code and Data to MGLI and GLI Follow the procedure in Table 3-13 to download the firmware application code for the MGLI. The download code action downloads data and also enables the MGLI. Prerequisite S Prior to performing this procedure, ensure a code file exists for each of the devices to be loaded. S The LMF computer is connected to the BTS (refer to Table 3-5), and is logged in using the GUI environment (refer to Table 3-6).
