QFX5700 Flexible PIC Concentrators

SUMMARY The QFX5K-FPC-20Y, QFX5K-FPC-16C, and QFX5K-FPC-4CD Flexible PIC Concentrators (FPCs) in a QFX5700 switch send and receive packets.

The QFX5700 switch supports three types of Flexible PIC Concentrators (FPCs) that are installed vertically in the front of the chassis: QFX5K-FPC-20Y, QFX5K-FPC-16C, and QFX5K-FPC-4CD. The QFX5700 chassis has nine FPC slots, but the chassis supports only eight FPCs in slots FPC 0 through 7. Slot 8 is empty. The QFX5700 switch supports a maximum of 144 logical ports.

FPCs are hot-removable and hot-insertable field-replaceable units (FRUs)—you can remove and replace them without powering off the switch or disrupting switch functions.

Green	On steadily	A link is established.
Amber	On steadily	The link is down because of a remote error or because the port was disabled through the CLI.
Red	On steadily	The port has a hardware failure or link down.

FPC Status LEDs

Power PWR bi-color red/green LED:

LEDs

Network LEDs

Each network port has a single tricolored LED that indicates link activity and status.

Unlit	Off	All channels are down because of signal loss.
Green	On steadily	A link is established and all channels are up.
Amber	On steadily	Applies to all other cases.
