Manually Booting the System
Caution
Do not overtighten the captive screws on the cards; you might strip the threads on
the screw or in the insert in the component faceplate.
•
Power modules are fully inserted in their bays and the ejector levers are
completely closed and secured.
•
Check the power module LEDs:
For a router equipped with AC-input power supplies, when a power supply is
seated in its bay and is receiving the required power source:
–
The green LED labeled AC should be on. It indicates that AC power
source is present and is within specified limits.
–
The green LED labeled DC should be on. It indicates that the power
supply is operating normally in a powered-on condition.
For a router equipped with DC-input PEMs—When a PEM is seated in its bay
and is receiving the required power source:
–
The green LED labeled INPUT OK should be on. It indicates that DC
power source is present and is within specified limits.
–
The green LED labeled OUTPUT OK should be on. It indicates that the
PEM is operating normally in a powered-on condition.
–
The amber LED labeled MISWIRE should be off. When it is on, it
indicates that the input is wired backward at the PDU input.
•
Each power module fan should also be on.
At the rear of the chassis, observe the status of the two LEDs on the blower
module. When the blower module is operating correctly, the left LED should
should be on (green) and the right LED (red) should be off.
Listen for the blowers in the blower module; they should be running. In a noisy
environment, the blower might be difficult to hear. In that case, place your hand
near the exhaust vents at the top and bottom rear of the chassis to verify that the
blower is operating.
