Before you install a 2x100GbE module, you will need to remove the center slot guide that divides
the slot into two partitions. Do not discard this guide, as you will need it if you ever want to convert
the slot into two slots. For information about how to remove the center guide and install high-speed
fabric modules, refer to the 2x100GbE module installation instructions in the appropriate
installation chapter for your router model.
NOTE
Before installing the 100GbE module in a chassis, the tm-credit-size must be changed to 1024
bytes.
You will also need to change the system tm credit size to 1024b (which readies the device to
forward 100 Gbps traffic). Log into your system and enter the following commands in the
configuration level of the CLI. Remember to write to memory and reload the device.
Brocade# config
Brocade(config)# system-init tm-credit-size credit_1024b
Brocade(config)# exit
Brocade# write memory
Brocade# reload
NOTE
The 100GbE module requires a minimum software version of R05.2.00. Please upgrade all software
on the system to a minimum version of R05.2.00 before you inst all your 2x100G module.
NOTE
100xGbE modules require high-speed switch fabric modules to operate.
