ACX7332 Flexible PIC Concentrator Maintenance

SUMMARY In this section learn how to remove and reinstall Flexible PIC Concentrators (FPCs).

Flexible PIC Concentrators (FPCs) on the ACX7332 router are field-replaceable units (FRUs) that can be installed in FPC slots on the front of the chassis. The FPCs are hot-pluggable—you can remove and replace them without powering off the router.

Before you replace an FPC from the router chassis:

  • Ensure that you have taken the necessary precautions to prevent electrostatic discharge (ESD) damage.

  • If there are any optical cables (including transceivers) installed in the FPC, remove them before you replace the FPC.

  • Ensure that you have the following equipment available before replacing an FPC:

    • Antistatic bag or antistatic mat

    • Replacement FPC or a cover for the empty slot

    • ESD grounding strap to wrap around your bare wrist and connect to an ESD point on the chassis

Remove a Flexible PIC Concentrator from the ACX7332 Router

To remove an FPC from an ACX7332 router chassis:

  1. Place an antistatic bag or an antistatic mat on a flat, stable surface.
  2. Wrap and fasten one end of the ESD grounding strap around your bare wrist, and connect the other end of the strap to an ESD point on the chassis. An ESD point is located on the front of the ACX7332 router (see #xd_97ca4427c072890e-38403db6-189f3ce8904--7d5f__fig_rw5_m4l_myb ).
  3. Label the cables connected to each port on the FPC so that you can reconnect the cables to the correct ports.
  4. Take the FPC offline by using the request-chassis-fpc slot slot-number offline command. Verify the status information by using the show chassis fpc command.
  5. To unlatch the ejector handles, grasp both the ejector handles using your hands by placing your thumb on top of the ejector handle and your index finger below the ejector handle. Pull down the ejector handles simultaneously and slide out the FPC out of the slot (see Figure 2).

  6. Place the FPC on the antistatic mat. Be careful not to bump or handle the FPC by the connectors. If you do not have an antistatic mat, have another person help you slide the antistatic bag over the FPC before placing it on a stable surface.
    CAUTION:

    Do not stack hardware components on top of one another after you remove them. Place each component on an antistatic mat resting on a stable, flat surface.
  7. If you are not replacing the FPC immediately, install a blank panel in the empty slot.

Install a Flexible PIC Concentrator in the ACX7332 Router

To install an FPC in the ACX7332 router chassis:

  1. Place an antistatic bag or an antistatic mat on a flat, stable surface.
  2. Wrap and fasten one end of the ESD grounding strap around your bare wrist, and connect the other end of the strap to an ESD point on the chassis. An ESD point is located on the front of the ACX7332 router (see #xd_97ca4427c072890e-38403db6-189f3ce8904--7d5f__fig_rw5_m4l_myb).
  3. Either remove the failing FPC (see Figure 2) or, if an FPC blank is installed, turn the thumb screws counter-clockwise on the handles on the blank and gently pull the blank out of the slot (see Figure 4).

  4. Remove the FPC from the antistatic bag, and inspect it for any damage before installing it in the chassis.
  5. Lift the FPC by the handle with one hand, and support the lower edge with the other hand.
  6. Gently slide the FPC into the open slot until the ejector handles engage and start to close.
  7. Using both hands, push the lower end of both the ejector handles until they latch to seat the FPC (see Figure 5).
