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 p
ower 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 t
erminal (labeled –48V).
3. Verify that a
n external management device is connected to one of the Routing Engine
ports o n the craft interface (AUX/MODEM, CONSOLE,orMGMT). For more information
on connecting management devices, see “Connect the Router to Management
Devices” on
page 61.
4. Turn on the p
ower to the external management device.
5. Press the p
ower switch for one power suppl y to the ON ( | ) position. On both AC and
DC power supplies, the switch is located on the power supply faceplate.
6. Verify that the OUTPUT OK LED on the power supply faceplate eventually lights steadily.
After powering off a power supply, wait at least 60 seconds before
turning i
t back on. After powering on a power supply, wait at least
60 seconds before turning it off.
If the router is completely powered down when you power on
the power supply, t he Routing Engine boots as the power supply
completes its startup sequence. If the Routing Engine finishes bo ot ing
and you need to power down the router again, first issue the CLI
request system halt command. For more information, see “Disconnect
ACPowerfromtheRouter”onpage102or“DisconnectDCPowerfrom
the Router” on page 109.
After a power supply is powered on, it can take up to 60 seconds for
status indicators—such as LEDs on the power supply and show chassis
commands—to indicate that the p ower supp ly is functioning normally.
Ignore error indicators that appear during the first 60 seconds.
7. Press the power switch for the second power supply to the ON ( | )positionand
verify that th e O
UTPUT OK LED on the power supply faceplate lights steadily. If the
LED does not light after 60 seconds, verify that the power supply is properly inserted
into the chassis and repeat the cable installation procedures described in “Connect
Power to an AC-P
owered Router” on page 65 or “Connect Power to a DC-Powered
Router” on page 66.
8. On the external management device connected to the Routing Engine, monitor the
startup process to verify that the system has booted properly.
