Installing 2x100GbE interface modules in Brocade MLX routers
3
CAUTION
For the NEBS-compliant installation of Brocade MLXe-32, routers with AC and DC systems, use a
ground wire of at least 2 American Wire Gauge (AWG). The ground wire should have an
agency-approved crimped connector (provided with the device) attached to one end, with the
other end attached to building ground. The connector must be crimped with the proper tool,
allowing it to be connected to both ground screws on the enclosure. Before crimping the ground
wire into the provided ground lug, ensure the bare copper wire has been cleaned and antioxidant
is applied to the bare wire.
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 Brocade
NetIron XMR4000 chassis. This restriction does not apply to Brocade MLXe 4-slot devices.
• 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.
