ACX7509 Flexible PIC Concentrator Maintenance

date_range 14-Mar-22

Maintaining ACX7509 routers includes removing and reinstalling Flexible PIC Concentrators (FPCs).

Flexible PIC Concentrators (FPCs) on the ACX7509 router are field-replaceable units (FRUs) that can be installed in FPC slots on the front of the chassis. The FPCs are hot-insertable and hot-removable: you can remove and replace them without powering off the router or disrupting router functions.

If you have the optional cable management system, it is not necessary to remove the cable management system before replacing an FPC.

The ACX7509 chassis supports JNP-FPC-16C, JNP-FPC-4CD, and JNP-FPC-20Y types of FPCs. The replacement procedure is the same for all three FPCs.

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 a Forwarding Engine Board (FEB):

Antistatic bag or antistatic mat
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 ACX7509 Router

To remove an FPC from a ACX7509 router chassis:

Place an antistatic bag or an antistatic mat on a flat, stable surface.
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 ACX7509 router (see Figure 1 ).
Label the cables connected to each port on the FPC so that you can reconnect the cables to the correct ports.
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.
Unlatch the ejector handles, and spread them apart. The FPC slides about a quarter of the way out of the slot. See Figure 2
Figure 2: Removing an ACX7509 FPC
Grasp the ejector handle with one hand and place your other hand under the FPC for support as you slide the FPC out of the slot.
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.

Install a Flexible PIC Concentrator in the ACX7509 Router

To install an FPC in the ACX7509 router chassis:

Place an antistatic bag or an antistatic mat on a flat, stable surface.
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 ACX7509 router (see Figure 1).
Either remove the failing FPC (see Remove a Flexible PIC Concentrator from the ACX7509 Router) or, if an FPC blank (JNP5K-FPC-BLNK) is installed, press the handles on the blank and gently pull the blank out of the slot (see Figure 3).
Figure 3: Removing the FPC Blank

CAUTION:
Do not lift the FPC by holding the edge connectors or the handles on the faceplate. Neither the handles nor the edge connectors can support the weight of the FPC. Lifting the FPC by the handles or edge connectors might bend the connectors, which would prevent the FPCs from being properly seated in the chassis.
Remove the FPC from the antistatic bag, and inspect it for any damage before installing it in the chassis.
Lift the FPC by the handle with one hand, and support the lower edge with the other hand.
Gently slide the FPC into the open slot until the ejector handles engage and start to close.
Grasp the two ejector handles, and fold them inward until they latch to seat the FPC (seeFigure 4).

Ensure that the ejectors are firmly locked in position (see Figure 5).
Figure 5: How to lock the ejectors
Bring the FPC online by using the request-chassis-fpc slot slot-number online command. Verify the status information by using the show chassis fpc command.
