Replacing equipment Page 87 of 250Hardware Replacement4 Get the status of the Cores, CNIs, and memories5 Load LD 137 and synchronize hard disks. Synchronization may takeup to 50 minutes. To be sure that the contents of IODU/C 1 are copiedto IODU/C 0, verify that IODU/C 0 is disabled.6 Get the status of the IODU/Cs and be sure IODU/C 0 is active. Switchif necessary.7 Insert the database diskette into both IODU/Cs for backup. Load LD 43and datadump. This creates a backup on the floppy disk in the activeIODU/C.8 Evaluate the number of call registers and telephone buffers that areconfigured for the system. Refer to Capacity Engineering(553-3001-149).The card replacement procedure is complete.Replacement procedure for Option 51C systemsTo perform this procedure, the following is required:• an Install diskette specific to your CP type• a CD-ROM containing system softwareSTAT CPU Get the status of both Cores.STAT CNI Get the status of all configured CNIs andmemories.LD 137STAT Get the status of both IODU/Cs and redundancy.SYNC Enter “Yes” to synchronize disks.Wait until the memory synchronizationsuccessfully completes before continuing.LD 137STAT Get the status of the IODU/Cs.SWAP Switch IODU/C (if necessary).STAT CMDU Get the status of the IODU/Cs. Be sure the sameIODU/C and CPU are active.LD 43EDDData dump complete (or database backup complete) is printed whenthe data dump has been successfully completed. Investigate any EDDmessages. Refer to Administration (553-3001-311).
