FC32-64 Port Blade Overview
The FC32-64 port blade contains 16 QSFP28 ports. Each QSFP optics supports four ports for connecting FC devices.
With a breakout cable connected to the QSFP transceiver, connections are provided for up to four devices.
Breakout capability allows four SFP+ front ports on qualified Fibre Channel and Ethernet QSFP transceivers to operate
at multiple speeds. For example, SFP+ front ports on an FC 4x32Gb/s SWL QSFP+ transceiver each operate at 32Gb/
s or four SFP+ front ports on a 40GbE QSFP+ transceiver can each operate at 10GbE. By default Ethernet ports
operate in non-breakout mode, so you must enable breakout mode for ports containing Ethernet transceivers using the
portcfgbreakout --enable command.
Connection speeds depend on the QSFP transceiver installed. For example, a 4x32Gb/s QSFP+ transceiver would
provide four 32/16Gb/s connections and a 4x16Gb/s QSFP+ transceiver provides four 16/8/4Gb/s connections.
The following list shows considerations for using these blades:
•
Port and extension blades can be mixed in device slots 3, 4, 7, and 8, but CR64-4 blades must be installed in slots 5
and 6. Up to four hot-swappable port blades can be installed in a single chassis to provide up to 192 32Gb/s FC ports.
•
It is recommended that two fan assemblies be installed on the X7-4 chassis if blades are being used.
Port blades contain the following LED indicators. For details on interpreting LED operation, see Supported Transceivers
and Cables.

Flexport allows you to configure individual ports on the FC32-64 blade for Fibre Channel (FC) or Fibre Channel over
Ethernet (FCoE) connections when qualified FC or Ethernet transceivers are installed in the ports. Configure FC (default)
or Ethernet operation for a port using the portcfgflexport command.
•
FC operation allows the connection of blades to fabric storage, servers, and switches. An FC transceiver must be
installed in a port to configure FC operation for that port. Supported FC transceivers include 4x32Gb/s QSFP28 and
4x16Gb/s QSFP+ transceivers.
•
FCoE operation allows the connection of blades to FCoE devices as part of a unified fabric. The FCoE devices can be
servers or connections through an FCoE Initialization Protocol snooping bridge (FSB). An Ethernet transceiver must be
installed in a port to configure FCoE operation for that port. Supported Ethernet transceivers include 40GbE, 4x10GbE,
and 4x25GbE QSFP+ transceivers.
