Powering on the M7i Router
To power on the router:
1.
Verify that the power supplies are fully inserted in the chassis and the thumbscrews
on their faceplates are tightened.
2.
For each power supply on an AC-powered router, verify that the ends of the power
cord are firmly plugged into the appliance inlet on the power supply faceplate and
the external power source receptacle.
For each power supply on a DC-powered router, verify that the source DC power cables
are connected to the appropriate terminal on the power supply faceplate: the positive
(+) source cable to the return terminal (labeled
RTN
) and the negative (–) source
cable to the input terminal (labeled
–48V
).
3.
Verify that an external management device is connected to one of the Routing Engine
ports on the Routing Engine (
AUX/MODEM
,
CONSOLE
, or
MGMT
). For more information
on connecting management devices, see “Connecting the M7i Router to Management
and Alarm Devices” on page 53.
4.
Turn on the power to the external management device.
5.
Press the power switch for one power supply to the
ON
(

) position. On both AC and
DC power supplies, the switch is located on the power supply faceplate.
