Installing an MX480 Routing Engine
To install a Routing Engine into an SCB ( Figure 95 on page 246 ):
1.
Attach an ESD grounding strap to your bare wrist and connect the strap to one of the
ESD points on the chassis.
2.
Ensure that the ejector handles are not in the locked position. If necessary, flip the
ejector handles outward.
3.
Place one hand underneath the Routing Engine to support it.
4.
Carefully align the sides of the Routing Engine with the guides inside the opening on
the SCB.
5.
Slide the Routing Engine into the SCB until you feel resistance, and then press the
Routing Engine's faceplate until it engages the connectors.
CAUTION: Align the Routing Engine correctly to avoid damaging it.
6.
Press both of the ejector handles inward to seat the Routing Engine.
7.
Tighten the captive screws on the left and right of the Routing Engine.
8.
Connect the management device cables to the Routing Engine.
The Routing Engine might require several minutes to boot.
After the Routing Engine boots, verify that it is installed correctly by checking the
FAIL
,
RE0
, and
RE1
LEDs on the craft interface. If the router is operational and the Routing
Engine is functioning properly, the green
ONLINE
LED lights steadily. If the red
FAIL
LED
lights steadily instead, remove and install the Routing Engine again. If the red FAIL LED
still lights steadily, the Routing Engine is not functioning properly. Contact your customer
support representative.
To check the status of the Routing Engine, use the CLI command:
user@host>
show chassis routing-engine
Routing Engine status: Slot 0: Current state Master ...
For more information about using the CLI, see the Junos OS documentation.
