Installing 2x100GbE interface modules in Brocade MLX routers

This section provides installation instructions for 2x100G interface modules.

Installation considerations

•
2x100G interface modules cannot be installed in slot 1 of a Brocade MLX 4-slot or a NetIron XMR4000 chassis.
•
2x100G modules occupy two adjacent slots. When you install a 2x100G module, the odd numbered (low number) slot of the slot
pair becomes the active slot, and the even numbered slot (higher number) is blocked.
The acceptable slots in which to install this module are odd-numbered interface module slots (1, 3, 5, 7, 9. 11, 13, and 15 for a
16-slot chassis, for example). Adjacent even-numbered slots will be in blocked state. In all cases, the lower number (odd number)
becomes the active slot and the higher number (even number) becomes the blocked slot.
•
2x100G modules cannot be installed in the following scenarios:
-
If there is another type of module installed in either of the slots
-
If either slot is configured as something else. Before you install your 2x100G module, you will need to reconfigure the slot
using the no module command.
•
The following conditions will prevent a 2x100G interface module from operating properly:
-
If either of the two slots required to house the module is already configured for another type of module.
If the higher-number slot (even number) is configured for another type of module, you must reconfigure it by entering the no
module command.
-
If there is a module of another type installed in either of the slots. You must remove the existing module, remove the center
slot guide, and reconfigure the higher-numbered (even number) of the two slots as no module.
•
For maximum performance you must operate your 2x100G module with high speed switch fabric modules in turbo mode.

Installation procedure

When installing modules, wear an ESD wrist strap with a plug for connection to the ESD connector on the router chassis or other suitable
ground.
For safety reasons, the ESD wrist strap should contain a 1 megohm series resistor.
1. Upgrade the software on all management modules and interface modules to Multi-Service IronWare R06.0.00 or later. For
specific upgrade instructions, refer to the <Italic>Multi-Service IronWare Upgrade Guide.
2. Before you install your 2x100G interface module into a working device, you must 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 system-init tm-credit-size command is only available in R05.2.00 or later, so it is important to upgrade all software to
R06.0.00 before you install your 2x100G module.
