Power On the MX480 Router
1.
Verify that the power supplies are fully inserted in the chassis.
2.
Verify that each AC power cord is securely inserted into its appliance inlet.
3.
Verify that an external management device is connected to one of the Routing Engine
ports (
AUX
,
CONSOLE
, or
ETHERNET
).
4.
Turn on the power to the external management device.
5.
Switch on the dedicated customer-site circuit breakers. Follow the ESD and safety
instructions for your site.
6.
Attach an ESD grounding strap to your bare wrist and connect the strap to one of the
ESD points on the chassis.
7.
Move the AC input switch on the chassis above the AC power supply or the DC circuit
breaker on each DC power-supply faceplate to the off
(—) position.
8.
Check that the AC or the DC power supply is correctly installed and functioning
normally. Verify that the
AC OK and DC OK LEDs light steadily, and the PS FAIL LED is
not lit.
NOTE: After a power supply is powered on, it can take up to 60 seconds
for status indicators—such as the status LEDs on the power supply and
the
show chassis command display—to indicate that the power supply is
functioning normally. Ignore error indicators that appear during the first
60 seconds.
If any of the status LEDs indicates that the power supply is not functioning normally,
repeat the installation and cabling procedures.
9.
On the external management device connected to the Routing Engine, monitor the
startup process to verify that the system has booted properly.
NOTE: If the system is completely powered off when you power on the
power supply, the Routing Engine boots as the power supply completes
its startup sequence. Normally, the router boots from the Junos OS on the
CompactFlash card.
After turning on a power supply, wait at least 60 seconds before turning
it off.
