FPCs for the M320 Router, the T320 Router, and the T640 Routing Node

This section describes the chassis, the supported FPCs, and how to replace FPCs for the M320 router, the T320 router, and the T640 routing node.

Chassis Descriptions

In the M320 and T320 routers and the T640 routing node, you can install up to eight FPCs vertically in the front of the routing platform. The FPCs are numbered FPC0 and E to FPC7 from left to right. Depending on the type, each FPC has two or four connectors into which you can install a PIC; this allows up to two or four PICs per FPC. You can install an FPC into any FPC slot on the routing platform regardless of which PICs it contains.

FPC Descriptions

This section describes the types of FPCs that each router supports.

M320 FPCs

The M320 router supports the following types of FPCs:

You can install any combination of these FPC types in the M320 router.

Faceplates on FPCs for the M320 router are labeled with the FPC type (FPC1, FPC2, or FPC3). The faceplates on Enhanced II FPCs are labeled E-II FPC1, E-II FPC2, or E-II FPC3.

Figure 16 shows the three types of FPCs that the M320 router supports.

You can distinguish an installed FPC1 from an FPC2 by looking at the PIC offline/online button. The button for PICs installed in an FPC1 is located slightly beneath the faceplate of the PIC. The button for PICs installed in an FPC2 is inside an opening directly on the faceplate of the PIC.

T320 FPCs

The T320 router supports the following types of FPCs:

You can install any combination of these FPC types in the T320 router.

You can tell the difference between the T320 FPC types by the different PICs installed in them:

Faceplates on Enhanced FPCs for the T320 router are labeled with the FPC type (FPC1, FPC2, or FPC3) and the letter E. The faceplates on Enhanced II FPCs are labeled E-II FPC1, E-II FPC2, or E-II FPC3.

Figure 18 shows the standard versions of the three types of FPCs that the T320 router supports. The enhanced versions look similar.

T640 FPCs

The T640 routing node supports the following types of FPCs:

You can install any combination of these FPC types in the T640 routing node.

You can tell the difference between installed T640 FPCs by the location of a PIC's offline button and how the PIC is secured to the FPC:

Also, faceplates on Enhanced FPCs for the T640 router are labeled with the FPC type (FPC1, FPC2, or FPC3) and the letter E. The faceplates on Enhanced II FPCs are labeled E-II FPC1, E-II FPC2, or E-II FPC3. The faceplate on the Enhanced Scaling FPC is labeled FPC4.

Figure 20 shows the enhanced version of the FPC1 and the standard versions of the FPC2 and FPC3 that the T640 routing node supports. The enhanced versions of the FPC2 and FPC3 look similar.

Figure 21 shows the Enhanced II versions of the FPC1, FPC2 and FPC3 that the T640 routing node supports.

Figure 22 shows the Enhanced Scaling version of the FPC4 that the T640 routing node supports.

FPC Components

Each M320 FPC has the following components:

Each T320 FPC has the following components:

Each T640 FPC has the following components:

Removing an FPC

An M320 router, T320 router, or T640 routing node holds up to eight FPCs, which you install vertically into the front of the routing platform.

Before you remove an FPC, be prepared to support its weight.

An empty M320 FPC1 or FPC2 weighs 15 lb (6.8 kg), and an empty M320 FPC3 weighs 16 lb (7.3 kg). A fully configured M320 FPC can weigh up to 29 lb (13.2 kg).

An empty T320 FPC1 weighs 14.3 lb (6.5 kg), an empty T320 FPC2 weighs 14.3 lb (6.5 kg), and an empty T320 FPC3 weighs 14.8 lb (6.7 kg). A fully configured T320 FPC can weigh up to 19 lb (8.6 kg).

An empty T640 FPC can weigh up to 25 lb (11.3 kg), and a fully configured T640 FPC can weigh up to 31.7 lb (14.4 kg).

Do not operate the routing platform with any of the FPC slots empty. When you remove an FPC, immediately install a replacement FPC or FPC blank panel to prevent overheating of routing platform components and to ensure compliance with electromagnetic radiation requirements (prevent radio interferrence).

To remove an FPC, follow this procedure:

  1. Have ready a replacement FPC or FPC blank panel and an antistatic mat for the FPC. Also have ready rubber safety caps for each PIC that uses an optical interface on the FPC that you are removing.
  2. Attach an ESD wrist strap to your bare wrist and connect the strap to one of the ESD points on the chassis.
  3. Label the cables connected to each PIC on the FPC, so that you can reconnect each cable to the correct PIC later.
  4. Use one of the following methods to take the FPC offline:
  5. Remove the cable connectors plugged into each PIC on the FPC. If a PIC uses fiber-optic cable, immediately cover each transceiver and the end of each cable with a rubber safety cap. Carefully arrange the disconnected cables in the cable management system to prevent the cables from developing stress points.

    Do not look directly into the ends of fiber-optic cables or into the transceivers on the interface faceplate. Single-mode fiber-optic cable and the interfaces that use it (such as ATM and SONET/SDH interfaces) emit laser light that can damage your eyes.

    Do not leave a fiber-optic transceiver uncovered except when inserting or removing cable. The safety cap keeps the port clean and prevents accidental exposure to laser light.

    Avoid bending fiber-optic cable beyond its minimum bend radius. An arc smaller than a few inches in diameter can damage the cable and cause problems that are difficult to diagnose.

  6. Carefully drape each disconnected cable over the bobbins on the cable management system below the FPC card cage to prevent the cables from developing stress points.
  7. Simultaneously turn both ejector handles counterclockwise to unseat the FPC.
  8. Grasp the handles, and slide the FPC straight out of the card cage halfway. Figure 23 shows how to pull an FPC out of a T320 router. The procedure is the same for the M320 router and T640 routing node.

    Figure 23: Removing an FPC from a T320 Router

  9. Place one hand around the front of the FPC (the PIC housing) and the other hand under it to support it. Slide the FPC completely out of the chassis, and place it on the antistatic mat or in the electrostatic bag.

    The weight of the FPC is concentrated in the back end. Be prepared to accept the full weight—up to 29 lb (13.2 kg) for an M320 router, up to 19 lb (8.6 kg) for a T320 router, or up to 31.7 lb (14.4 kg) for a T640 routing node—as you slide the FPC out of the chassis.

    When the FPC is out of the chassis, do not hold it by the ejector handles or edge connectors. They cannot support its weight.

    Do not stack FPCs on one another after removal. Place each one individually into an electrostatic bag or on its own antistatic mat on a flat, stable surface.

  10. If necessary, remove each additional installed PIC from the FPC.
  11. After you remove each PIC, immediately place it on an antistatic mat or in an electrostatic bag.
  12. If you are not replacing the FPC now, install a blank panel over the slot to maintain proper airflow in the FPC card cage.

    After removing an FPC from the chassis, wait at least 30 seconds before reinserting it, removing an FPC from a different slot, or inserting an FPC into a different slot.

Installing an FPC

To install a replacement FPC, follow this procedure:

  1. Attach an ESD wrist strap to your bare wrist and connect the strap to one of the ESD points on the chassis.
  2. Place the replacement FPC on an antistatic mat.

    When the FPC is out of the chassis, do not hold it by the ejector handles or edge connectors. They cannot support its weight.

  3. You must install or remove PICs before installing the FPC into the chassis. See the PIC, SFP, and XENPAK Installation Instructions. If any PICs use fiber-optic cable, make sure that each transceiver is covered with a rubber safety cap.
  4. Grasp the front of the FPC with both hands. Orient the FPC vertically (see Figure 2) with the component side facing to the right. Be sure the FPC is right-side up.
  5. Tilt the top of the FPC toward you slightly.
  6. Carefully align the connector edge of the FPC with an empty slot in the chassis.
  7. Gently rest the bottom edge of the FPC on the bottom edge of the slot opening. Do not rest the power connector on the slot.

    The FPC power connector is in the corner where the bottom and connector edges meet. If a power connector prong becomes bent, it no longer aligns with the female connector on the midplane, and the FPC no longer functions. Do not bend or otherwise damage the power connector prongs (see Figure 24).

  8. Tilt the top of the FPC toward the chassis until the FPC is completely vertical.
  9. Slowly slide the FPC all the way into the card cage until you feel resistance. Figure 25 shows how to slide an FPC into a T320 router. The procedure is the same for the M320 router and the T640 routing node.

    Figure 25: Installing a Replacement FPC in a T320 Router

  10. Align the ejector handles on the FPC faceplate in a position close to horizontal.
  11. Simultaneously turn both ejector handles clockwise until you cannot turn them farther.
  12. Remove the rubber safety cap from each fiber-optic PIC transceiver.

    Do not look directly into the ends of fiber-optic cables or into the transceivers on the interface faceplate. Single-mode fiber-optic cable and the interfaces that use it (such as ATM and SONET/SDH interfaces) emit laser light that can damage your eyes.

  13. Insert the appropriate cable into the ports on each PIC transceiver on the FPC (see Figure 26).

    Figure 26: Connecting Fiber-Optic Cable to a PIC

    Image g002279.gif

  14. Secure the cables so that they do not support their own weight. Use the cable management system to place excess cable out of the way in a neatly-coiled loop,

    Do not let fiber-optic cable hang free from the connector. Do not allow fastened loops of cable to dangle, which stresses the cable at the fastening point.

  15. Press and hold the FPC offline button until the green OK LED next to the button lights steadily in about 5 seconds. The LED and offline button for each FPC are directly above the FPC on the craft interface.
