QFX5700 Flexible PIC Concentrator Maintenance
Maintaining QFX5700 switches includes removing and reinstalling Flexible PIC Concentrators (FPCs).
Flexible PIC Concentrators (FPCs) on the QFX5700 switch 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 switch or disrupting switch functions.
If you have the optional cable management system, it is not necessary to remove the cable management system before replacing an FPC.
The QFX5700 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 switch 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 QFX5700 Switch
To remove an FPC from a QFX5700 switch chassis:
- 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 a QFX5700 FPC
Install a Flexible PIC Concentrator in the QFX5700 Switch
To install an FPC in the QFX5700 switch chassis:
- Either remove the failing FPC (see Remove a Flexible PIC Concentrator from the QFX5700 Switch) 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.
- Grasp the two ejector handles, and fold them inward until they latch to
seat the FPC (seeFigure 4). Figure 4: Installing a QFX5700 FPC
