PICs for the M320 Router, the T320 Router, the T640 Routing Node, and the T1600 Routing Node

PICs on the M320 and T320 routers and the T640 and T1600 routing nodes are hot-insertable and hot-removable, so you can remove and replace them without powering off the router. Removing a PIC does not affect router function, except that the PIC no longer receives or transmits data.

Removing a PIC from an M320 Router, a T320 Router, a T640 Routing Node, or a T1600 Routing Node

To remove a PIC from an M320 router, a T320 router, a T640 routing node, or a T1600 routing node (see Figure 9, Figure 10, Figure 11, or Figure 12, respectively):

1. Place an electrostatic bag or antistatic mat on a flat, stable surface to receive the PIC. If the PIC uses fiber-optic cable, have ready a rubber safety cap for each transceiver and cable.
2. Attach an ESD wrist strap to your bare wrist and connect the wrist strap to one of the ESD points on the chassis.
3. Take the PIC offline. Press and hold the button until the PIC LED turns off (about 5 seconds). On the M320 and T320 routers, the offline button for PICs installed in a Type 1 FPC is located on the FPC faceplate.
4. Label the cables connected to the PIC so that you can later reconnect each cable to the correct PIC.
5. Remove the cable connector plugged into the PIC and immediately place a rubber safety cap over the transceiver.
6. Carefully drape the disconnected cable over the bobbins in the cable management system below the FPC card cage to prevent the cable from developing stress points.
7. For a PIC installed in a Type 1 FPC or Type 2 FPC, loosen the captive screws at the top and bottom of the faceplate. For a Type 3 FPC PIC, loosen the captive screw at the bottom of the PIC faceplate, and then twist the ejector handle at the top of the faceplate counterclockwise to unseat the PIC.
8. Slide the PIC out of the FPC.
9. Place the removed PIC on the antistatic mat or electrostatic bag that you prepared in Step 1.

Installing a PIC in an M320 Router, a T320 Router, a T640 Routing Node, or a T1600 Routing Node

To install a PIC in an M320 router, a T320 router, a T640 routing node, or a T1600 routing node (see Figure 13, Figure 14, Figure 15, or Figure 16, respectively):

1. Attach an ESD wrist strap to your bare wrist and connect the wrist strap to one of the ESD points on the chassis.
2. Take the replacement PIC out of its electrostatic bag and place it on an antistatic mat.
3. Each PIC with a fiber-optic transceiver should have a rubber safety cap covering the transceiver. If it does not, place a safety cap over the transceiver.
4. Slide each PIC into the appropriate slot in the FPC, aligning the notches at the rear connector on the PIC with the notches in the FPC.

   Caution: Be careful to insert the PIC straight into the FPC to avoid damaging the exposed components on the PIC.

5. For a PIC installed in a Type 3 FPC, turn the ejector handle at the top of the PIC faceplate clockwise, and then tighten the captive screw at the bottom of the faceplate to secure the PIC in the FPC. For a PIC installed in a Type 1 FPC or Type 2 FPC, tighten the captive screws at the top and bottom of the faceplate.
6. Remove the rubber safety cap from the transceiver.
7. Connect the appropriate cable connector to the transceiver.
8. Carefully drape the PIC cable over the bobbins of the cable management system below the FPC card cage to prevent the cables from developing stress points.
9. To bring the PIC online, press the PIC offline button until the PIC LED lights green. The offline button for PICs installed in a Type 1 FPC is located on the FPC faceplate.

   Note: For a PIC to function, you must add the necessary statements for it to the router configuration. For instructions, see the JUNOS Network Interfaces Configuration Guide.
