Appendix A. Cable and Port Specifications
CAUTION: We strongly recommend that power cable runs and other potential noise sources be
located as far away as practical from network cabling that terminates at Cisco equipment. In
situations where long parallel cable runs exist, but cannot be separated by at least 3.3 ft. (1 m), we
recommend that you shield these potential noise sources. To avoid interference, the source should
be shielded by housing it in a grounded metallic conduit.
Cables and Adapters
The IBM SAN48C-6 Switch accessory kit includes the following:
• RJ-45-to-RJ-45 rollover cable
• RJ-45-to-DB-9 female DTE adapter (labeled Terminal)
• RJ-45-to-DB-25 female DTE adapter (labeled Terminal)
• RJ-45-to-DB-25 male DCE adapter (labeled Modem)

Console Port
The console port is an asynchronous RS-232 serial port with an RJ-45 connector. You can use the RJ-45-
to-RJ-45 rollover cable and the RJ-45-to-DB-9 female adapter or the RJ-45-to-DB-25 female DTE
adapter (depending on your computer serial port) to connect the console port to a computer running
terminal emulation software.
