Cable and Adapter Specifications

Console Port

The console port uses an 8-pin RJ-45 connector, which is described in Table B-4and Table B-5. The supplied RJ-45-to-DB-9 adapter cable is used to connect the console port of the switch module to a console PC. You need to provide a RJ-45-to-DB-25 female DTE adapter if you want to connect the switch module console port to a terminal. You can order a kit (part number ACS-DSBUASYN=) containing that adapter from Cisco. For console port and adapter pinout information, see Table B-4and Table B-5.

10-Gigabit Ethernet X2 Transceiver Module Cable Specifications

Table B-1lists the port cabling specifications for the 10-Gigabit Ethernet X2 transceiver modules. Each port must match the wave-length specifications on the other end of the cable, and for reliable communications, the cable must not exceed the stipulated cable length. Table B-2lists the transceiver optical send and receive specifications.
