Installing 2x100GbE interface modules in Brocade MLXe routers

2

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. 

DANGER

1. Upgrade the software on all management modules and interface modules to Multi-Service 

IronWare R05.2.00 or later. For specific upgrade instructions, refer to the 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 R05.2.00 before you install your 2x100G module.

3. Remove the center slot guide. In some devices, you must lift a plunger to remove the center 

slot guide. Be sure to keep the plunger raised so that it does not reseat while you are removing 
the guide. In some devices, you must loosen a screw to remove the center slot guide. 

shows the two types of center slot guides.

Remove the guide carefully so that it does not move from side to side. Excess movement of the 
guide may damage pins on the backplane before it is fully removed from the chassis.

NOTE

Do not discard the center slot guide, as you will need it if you want to revert to a 2-slot 
configuration. If you misplace your center slot guide, you can purchase a replacement from 
Brocade.
