Attach an electrostatic discharge (ESD) grounding strap to your bare
wrist and connect the strap to one of the ESD points on the chassis. For more information about ESD, see Preventing
Electrostatic Discharge Damage.
Verify that the power
supplies are fully inserted in the chassis.
Verify that the AC power cord is securely inserted
into the appliance inlet.
Turn on the power to the external management device.
Switch the AC switch on each power supply to the
on position (|) and observe the status LEDs on each power
supply faceplate. If an AC power supply is correctly installed and
functioning normally, the AC OK and DC OK LEDs light steadily, and the PS FAIL LED is not lit.
If any of the status LEDs indicates that the power supply is
not functioning normally, repeat the installation and cabling procedures
described in Replacing Power System Components.
After powering off a power supply, wait at least 60 seconds
before turning it back on. After powering on a power supply, wait
at least 60 seconds before turning it off.
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. If the Routing Engine finishes booting and you
need to power off the system again, see .
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.
external management device connected to the Routing Engine, monitor
the startup process to verify that the system has booted properly.
