DB-9 Connector Pinouts for the M7i Routing Engine AUX/MODEM and CONSOLE Ports
The ports on the CIP labeled AUX/MODEM and CONSOLE are DB-9 receptacles that
accept RS-232 (EIA-232) cable. The AUX/MODEM 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). Table
29 on page 186 describes the DB-9 connector pinouts.
