Router modules
DRAFT: BROCADE CONFIDENTIAL
Depending on your router model, you can install up to 32 single-slot interface modules, or 16 double-slot interface modules.
Interface modules are hot-swappable, which means you can remove and replace them without powering down the system.
NOTE
For the latest and most up to date information on modules supported on MLX and XMR chassis, log in to

and access the TECH NOTE: BROCADE MLX SERIES MODULE SUPPORT document.
NOTE
Specific information regarding RAD optics configuration on the Brocade MLX Series and NetIron XMR platforms has been
documented in the RAD optics Solutions test report. Please work with your account team to gain access to the document.
100xGbE 2-port interface module
The 100xGbE 2-port interface module is supported on all Brocade MLX Series and NetIron XMR routers. This interface module has two
100 Gbps CFP optics ports, 2 Gbps memory, an internal flash of 32MB for local storage of CPU images, and 64MB for local storage of
FPGA images. The 100xGbE 2-port interface module supports 1.5 GB buffering per port.
NOTE
Brocade MLX and NetIron XMR models support one port only.
The 100xGbE interface module occupies two interface module slots in any chassis, with one slot active and one slot inactive. In all devices,
the lower number of the two occupied slots becomes the active slot.
NOTE
Because of the possibility of overheating, 2x100GbE interface modules must not be installed in the top slot of a Brocade MLX or
XMR 4-slot chassis.
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
