Refer to "Supported transceivers and cables" on page 65 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." Color coding on the physical blade identifies the port groups. 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:
|
v 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.
|
v You can use from 1–8 ports in a port group to form a trunk.
|
v All ports in a trunk must be running at the same speed.
|
v All ports in a trunk must be configured for the same distance.
|
|
v All ports in a trunk must have the same encryption, compression, QoS, and FEC settings.
v 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.
|
v 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 port has four front SFP+ ports for
|
connecting FC devices. With a breakout cable connected to the QSFP transceiver, SFP+ connections are
|
|
provided for up to four devices. Connection speeds depend on the QSFP transceiver installed. For
example, a 4x32 Gbps QSFP+ transceiver would provide four 32/16 Gbps connections and a 4x16 Gbps
|
QSFP+ transceiver provides four 16/8/4 Gbps connections.
