CHAPTER 2 NDA-24238 Pag e 3 4 Revision 3.0 SYSTEM MAINTENANCE OUTLINE History of fault When did the fault occur? What kind of repair procedure has been executed? Does the fault still exist or not exist? etc. Range of fault Range of fault should be reported: Single line?, Specific trunk?, Specific circuit card?, Specific PIM?, Whole system?, etc. (2) Circuit Card Version Number, Program Name, and Program Package Version Number of the circuit card. See Figure 2-26.

NDA-24238 CHAPTER 2 Page 35 Revision 3.0 SYSTEM MAINTENANCE OUTLINE 4.2 Forwarding Faulty Circuit Card Method Send the faulty circuit card to the NEC agent to whom a request is made for a replacement card. Adhere to the following procedure for sending the faulty circuit card: (1) Insert connector covers onto the circuit card terminals. (2) Put the circuit card into a static electricity protective bag. (3) Pack the circuit card with air cap, etc. (4) Set the circuit card into the cardboard box for that specific circuit card. (5) If multiple circuit cards are to be sent, set each circuit card in a separate cardboard box and stuff the box with shock absorbing material. Note:When sending a faulty circuit card, put it in a static guard bag. To prevent damage, never place the cir- cuit card in a vinyl bag or ship it without a protective bag.
