Installing 2x100GbE interface modules in NetIron XMR routers
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.
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 89 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.
