Cables and Adapters
SFP Module Cables
Each port must match the wave-length specifications on each end of the cable, and for reliable communications,
the cable must not exceed the allowable length.
For more information about SFP/SFP+ modules and cables, see Transceiver Modules .
Console Port Adapter Pinouts
The console port uses an 8-pin RJ-45 connector. If you did not order a console cable, you need to provide an
RJ-45-to-DB-9 adapter cable to connect the router console port to a PC console port. You need to provide an
RJ-45-to-DB-25 female DTE adapter if you want to connect the router console port to a terminal. You can
order an adapter (part number ACS-DSBUASYN=).
The following table shows the pinout descriptions for the DB-9 connections:
