Purpose

For optimum router performance, verify the condition of the Routing Engine on regular basis.

Action

On a regular basis:

Check the LEDs on the front panel to view information about the status of the Routing Engine.

To check the status of the Routing Engine, issue the show chassis routing-engine command. The output is similar to the following:

Remove an MX304 Routing Engine

The MX304 host subsystem has up to two Routing Engines.

To remove a Routing Engine (see Figure 1 ):

CAUTION:

Before removing a Routing Engine, make sure you know how to properly use the ejector handles to avoid damage to the equipment.

CAUTION:

Before you replace a Routing Engine, you must take the host subsystem offline. If there's only one host subsystem, the router shuts down when you take it offline.

Take the host subsystem offline.
Place an electrostatic bag or antistatic mat on a flat, stable surface.
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
Open the ejector handle outward to unseat the Routing Engine.
Grasp the ejector handle, and slide the Routing Engine about halfway out of the chassis. See Figure 1.
Figure 1: Removing an Routing Engine
Place one hand underneath the Routing Engine to support it, and slide it completely out of the chassis.
Place the Routing Engine on the antistatic mat or into an antistatic bag.

Note:
If you plan to re-insert the Routing Engine, wait for atleast 1 minute or more and then re-insert back into the chassis.
If you are not replacing the Routing Engine immediately, install a blank panel over the empty slot.

Install an MX304 Routing Engine

To install an MX304 Routing Engine (see Figure 2):

Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
Remove the Routing Engine from the electrostatic bag.
Carefully align the sides of the Routing Engine with the guides inside the chassis.
Slide the Routing Engine into the chassis until you feel resistance, carefully ensuring that it's correctly aligned.
Grasp the ejector handles, and gently close them simultaneously until the Routing Engine is fully seated. Turn the ejector handles clockwise until they lock.
Figure 2: Installing an MX304 Routing Engine
Check the LEDs on the Routing Engine faceplate to verify that it's functioning normally:
- The green OK/FAIL LED should light steadily a few minutes after you install the Routing Engine.
- If the OK/FAIL LED is red, remove and install the Routing Engine again. If the OK/FAIL LED still lights steadily, the Routing Engine isn't functioning properly. Contact your customer support representative. See Contact Customer Support.

Check the Routing Engine status by using the
