Replacing the CIP on the M40e Router

Removing the M40e CIP

To remove the CIP (see Figure 1):

1. Place an electrostatic bag or antistatic mat on a flat, stable surface.
2. On the console or other management device connected to the master Routing Engine, enter CLI operational mode and issue the following command to shut down the router software. (If two Routing Engines are installed, also issue the command on the backup Routing Engine.)
   
   

   user@host> request system halt

   Wait until a message appears on the console confirming that the operating system has halted.

   For more information about the command, see the Junos System Basics and Services Command Reference.

   Note: The SFM might continue forwarding traffic for approximately 5 minutes after the request system halt command has been issued.

3. Press the power switch for both power supplies to the OFF (0) position. On an AC-powered router, the switch for each power supply is on the power supply faceplate. On a DC-powered router, the switches are on the circuit breaker box.
4. 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 to an M Series, MX Series, or T Series Router.
5. Disconnect any external devices connected to the CIP. For instructions, see Replacing the M40e Management Ethernet Cable, Replacing the M40e Console or Auxiliary Cable, and Replacing Alarm Relay Wires on the M40e Router.
6. Using a Phillips screwdriver, loosen and remove the screw at each end of the CIP faceplate.
7. Grasp the CIP and slide it out of the chassis. Place it in the electrostatic bag or on the antistatic mat.

   Caution: Be sure to slide the CIP straight within the slot to avoid damaging the connector pins on the front of the midplane.

Installing the M40e CIP

To install the CIP (see Figure 2):

1. Verify that the router is powered down.
2. Carefully insert the rear of the CIP into the guides at the top and bottom of the CIP slot, which is located to the left of the FPC card cage.

   Note: The components on the CIP are on the left side of the board, unlike the components of an FPC, which are on the right side. Verify that the components are on the left before inserting the CIP.

3. Slide the CIP into the chassis until it contacts the midplane.

   Caution: Be sure to slide the CIP straight within the slot to avoid damaging the connector pins on the front of the midplane.

4. Using a Phillips screwdriver, tighten the screw at each end of the CIP faceplate.
5. Reattach an external management device to one of the Routing Engine ports on the CIP (AUXILIARY, CONSOLE, or ETHERNET). Also reattach alarm relay contacts if desired. For instructions, see Replacing the M40e Management Ethernet Cable, Replacing the M40e Console or Auxiliary Cable, and Replacing Alarm Relay Wires on the M40e Router.
6. Power on the router and verify correct startup by performing the procedures in Connecting AC Power to the M40e Router for AC power orConnecting DC Power to the M40e Router for DC power.
