yet developed. The Serial Interface Processor (SIP, SX-SIP, or PRE-FSIP) provided an interim
solution until the FSIP was released in September 1993 with Software Release 9.17(5). The FSIP is
now the default serial interface processor for Cisco 7000 series routers. The SIP can no longer be
ordered, and no new microcode or feature enhancements for it will be released. An FSIP upgrade
program is currently in progress to replace all SIPs in the field with new FSIPs. If you currently have
SIPs running in your Cisco 7000, we encourage you to replace them as soon as possible; the upgrade
is free of charge. Contact a service representative for information about the upgrade.
If you are replacing SIPs with new FSIPs, refer to the instructions in the document Replacing SIPs
with FSIPs in the Cisco 7000 (Document Number 78-1191-xx) before proceeding.
If you are installing a new FSIP in an installed Cisco 7000, ensure that your system meets the
required minimum configuration for FSIP operation before proceeding: Maintenance Release
9.17(5) and SP Microcode Version 1.4. (For a description of prerequisites, refer to the section
