R4.3 CTL & INTEG. CALLP/PNNI UPGRADE KIT This kit is used to upgrade an R4.3 Control or Integrated CallP/PNNI card to the enhanced Processor Module(ePM) and larger NOR Based (256M) memory card. Factory shipments of R4.3 Control and Integrated CallP/PNNI cards ship with the ePM installed, and with the larger memory card included, and do not require this upgrade kit. The kit contains an ePM (333 MHz PowerPC 755 module with 512M RAM), 256M memory card, part number labels, and instructions for installation. Note: The NOR-Based memory card is replaced by a NAND-based memory card for later loadsets of R4.3. Be aware that this part supplies the older NOR based memory card and that you should check with Product Management before ordering this part. Field Notice FN1867 provides more details.
