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
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 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.
Figure 42
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.
