CHAPTER 4 NDA-24307 Page 324 Issue 1 UNIT/CIRCUIT CARD REPLACEMENT PROCEDURE 3.3.5 SDT Card Replacement Procedure The SDT (PA-SDTA/PA-SDTB) card, mounted in a universal slot of a PIM, is used to provide a 52M interface for the optical fiber lines. Use the following procedure to replace the SDT card with a spare. Optical Fiber Cable Replacement Procedure ATTENTIONContents Static Sensitive Handling Precautions Required ATTENTIONContents Static Sensitive Handling Precautions Required While this card is being replaced, the connected optical fiber line cannot be used.WARNING ACT lamp on the PA-SDTA card goes OFF. (When the card is provided in a dual configuration, the card becomes stand-by.) The following occurs in call processing: When card is provided in dual configuration All calls (including already established calls plus newly attempted calls) can normally be handled by the mate card. When card is in single configuration, or mate card is faulty in dual configuration Though any call attempt is rejected, already established calls are not affected. When any connection link exists, the link is still maintained. OPE lamp on the PA-SDTA card lights red. The following occur in call processing: When card is in single configuration, or mate card is faulty in dual configuration Already established calls (while in speech) lose voice/tone. Any connection link is severed after a few seconds. ATTENTIONContents Static Sensitive Handling Precautions Required A START On the PA-SDTA card, turn ON Switch 4 of the P-SW key. On the PA-SDTA card, set the MB key UP (=ON).

Though any call attempt is rejected, already established calls are safely maintained. When any connection link exists, the link is maintained. Note:When the card is in a dual configuration, perform this for both system sides, in the order of STBY → ACT. OPE lamp on the PA-SDTA card lights red. When already established calls exist, the connections lose voice/tone. When any connection link exists, the link is severed after a few seconds. Note:When the card is in a dual configuration, perform this for both system sides ( ACT and STBY). A START On the PA-SDTA card, turn ON Switch 4 of the P-SW key. On the PA-SDTA card, set the MB key UP (=ON). By using the SPTS command, verify that no calls are being handled by the SDT card.
NDA-24307 CHAPTER 4 Page 327 Issue 1 UNIT/CIRCUIT CARD REPLACEMENT PROCEDURE ATTENTIONContents Static Sensitive Handling Precautions Required OPE lamp on the PA-SDTB card lights red. When any connection link exists, the nailed-down connection between the FCH (PA-FCHA) and SDT (PA- SDTB) cards is cut off. Already established calls, while in speech, are all disconnected. Confirm that the MB key on the new card is set UP (=ON). If the new card is PA-SDTA, also confirm that Switch 4 of the P-SW key is ON. B A Referring to the card removed, perform the switch settings on the new card. On the PA-SDTB card, set the MB key UP (=ON). Remove the flat cables from the front connectors, I/O and PCM, on both PA-SDTB and PA-SDTA cards. When replacing the PA-SDTB, also remove MT24 TSW cables from all the front connectors on the card. Extract both PA-SDTA/PA-SDTB cards, simultaneously.

OPE lamp on the new card lights steady-green. END B On the PA-SDTA card, turn OFF Switch 4 of the P-SW key. Insert both PA-SDTA/PA-SDTB cards (including new card) simultaneously into the same slots of the PIM. When the new card is PA-SDTB, also connect the MT 24 TSW cables to all the required front connectors. On the PA-SDTB card, set the MB key DOWN (=OFF). On the PA-SDTA card, set the MB key DOWN (=OFF). Connect the disconnected flat cables to the connectors on the new card and other PA-SDTA/PA-SDTB cards. Note: When the card is in a dual configuration, perform this action for both system sides ( ACT and STBY). Note:When the card is in a dual configuration, perform this action for both system sides, in the order of STBY → ACT.

UNIT/CIRCUIT CARD REPLACEMENT PROCEDURE
3.3.6 DLMX Card Replacement Procedure
The DLMX (PA-PC94) card, accommodated in a universal slot of a PIM, is used to
collect the BLF information (associated with Attendant/Desk Console operation)
from DLKC cards of all nodes in the IPX-U system, and to send the collected data
to ATI cards of all nodes. When replacing this card, take the procedure below:

NDA-24307 CHAPTER 4 Page 331 Issue 1 UNIT/CIRCUIT CARD REPLACEMENT PROCEDURE 4. ISWM ACCOMMODATING CIRCUIT CARD REPLACEMENT PROCEDURE This section explains the procedure for replacing circuit cards mounted in the ISWM. 4.1 Precautions Use this procedure to replace a faulty circuit card with a spare or to check a spare card. There are the functional switches (having set the default switch) on some of the circuit cards to be replaced. As for switch setting on the circuit cards, confirm the circuit card mounting face layout for the PIM. When a circuit card with a default switch setting is replaced with a spare card, always make the switch setting on the new circuit card the same as on the replaced card. Otherwise, electronic components on the circuit card may be destroyed, or the circuit card itself may fail to function normally. When handling a circuit card, always use the field service kit for countermeasures against static electricity. Touching a circuit card without using the field service kit may destroy the card due to static electricity on the human body. 4.2 Circuit Card Mounting Face Layout Figure 4-10 shows the face layout of the circuit cards mounted in the TSWM. The circuit cards marked with * are optional.

CHAPTER 4 NDA-24307 Page 332 Issue 1 UNIT/CIRCUIT CARD REPLACEMENT PROCEDURE 4.3 Operating Procedures The following section provide operating procedures to replace circuit cards mounted in the ISW. Perform the operations corresponding to each reference item specified in Table 4-4. The procedures assume that the system adopts the dual configuration. Table 4-4 ISW Circuit Cards and Reference Items CIRCUIT CARD FUNCTION NAMEREFERENCE ITEM REMARKS IOGTSection 4.3.1, IOGT Card Replacement Procedure TSWSection 4.3.2, TSW Card Replacement Procedure HSWSection 4.3.3, HSW Card Replacement Procedure PLOSection 4.3.4, PLO Card Replacement Procedure PWR SWSection 4.3.5, PWR SW Card Replacement Procedure Improper key operations may result in a system down. Operate the key using extreme care. During replacement of a circuit card, the system issues system messages and activates the related alarm. Reset the indicated alarm after completing the replacement procedure. If the indicated alarm is cleared via the RALM/RALMN command, the system also clears the contents of the system message. Before using the RALM/RALMN command, print the messages using the DFTD command. Use the ALM RST button on the TOPU only to reset the alarm lamps.WA R N I N G
