The router attempts to boot from three devices in this order:
•
PC Card
•
CompactFlash card
•
Hard disk
NOTE:
If the router boots from an alternate boot device, a yellow alarm lights
the LED on the router’s craft interface.
M7i Routing Engine Management Ports
On the right half of the Routing Engine are ports for connecting the Routing Engine to
one or more external devices on which system administrators can issue Junos OS
command-line interface (CLI) commands to manage the router.
The ports are labeled and function as follows:
•
CONSOLE
—Connects the Routing Engine to a system console through an RS-232
(EIA-232) serial cable.
•
AUX/MODEM
— Connects the Routing Engine to a laptop, modem, or other auxiliary
device through an RS-232 (EIA-232) serial cable.
•
MGMT
—Connects the Routing Engine through an Ethernet connection to a management
LAN (or any other device that plugs into an Ethernet connection) for out-of-band
management. The port uses an autosensing RJ-45 connector to support both 10- and
100-Mbps connections. Two small LEDs on the left edge of the port indicate the
connection in use: the yellow LED lights for a 10-Mbps connection and the green LED
lights for a 100-Mbps connection.
For information about the pinouts for the connectors, see “RJ-45 Connector Pinouts for
the M7i Routing Engine MGMT Port” on page 181.
Figure 13 on page 20 shows the ports that connect to the Routing Engine.
