DB-9 Connector Pinouts for the Routing Engine Console and Auxiliary Ports
The ports on the craft interface labeled AUXILIARY and CONSOLE are DB-9 receptacles that
accept RS-232 (EIA-232) cable. The
AUXILIARY port connects the Routing Engine to a laptop,
modem, or other auxiliary unit, and the
CONSOLE port connects it to a management console.
The ports are configured as data terminal equipment (DTE). For more information, see
“Routing Engine LEDs and Interface Ports” on page 19. Table 25 describes the DB-9
connector pinouts.
