2. FC Ports 24–47 (numbered bottom to top)
The following figure shows how ports are numbered on the blade.
See
Supported Transceivers and Cables
for a list of qualified transceivers for blade ports.
The following table defines the eight-port Fibre Channel port groups for configuring trunk groups or "trunks." On the blade,
ports belonging to the same port group are indicated with the same color border beneath the port on the blade label. Ports
belonging to the same ASIC are indicated by a border with a similar color tone.

Following are the requirements for forming trunk groups:
•
All ports in a trunk group must belong to the same port group. For example, to form an 8-port trunk select all eight ports
from port group 0 or port group 1. You cannot use ports from each port group for the trunk.
•
You can use from 1 to 8 ports in a port group to form a trunk.
•
All ports in a trunk must be running at the same speed.
•
All ports in a trunk must be configured for the same distance.
•
All ports in a trunk must have the same encryption, compression, QoS, and FEC settings.
•
Trunk groups must be created between Brocade switches (or Brocade adapters in the case of F_Port trunking).
Brocade trunking is proprietary and is not supported on M-EOS or third-party switches.
•
There must be a direct connection between participating switches.
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 3–6 and 9–12, but CR64-8 blades must be installed in slots 7
and 8. Up to eight hot-swappable port blades can be installed in a single chassis to provide up to 384 32Gb/s FC ports.
•
It is recommended that three fan assemblies be installed on the X7-8 chassis if blades are being used.
