Installing a Brocade MLX-16 router
DRAFT: BROCADE CONFIDENTIAL
Installation instructions are identical for interface, management, and switch fabric modules. However, there are specific switch fabric and
fan requirements for NI-MLX-10Gx8-M and NI-MLX-1Gx48-T-A modules in the 16-slot router. Refer to “Fan and switch fabric
requirements for NI-MLX-10Gx8-M and NI-MLX-1Gx48-T-A, NI-MLX-1Gx48-T interface modules in 16-slot routers” on page 68 and
“Installing Brocade MLX-16 router modules” on page 67.
For instructions about installing 100xGbE interface modules, refer to “Installing 2x100GbE interface modules in Brocade MLX routers” on
page 43.
Modules for the Brocade MLX-16 router are hot-swappable, which means you can remove and replace them while the router is powered
on and running. However, for a graceful shutdown of the links on switch fabric modules, it is recommended that you disable the switch
fabric module before removing it from the router.
For information about how to disable and re-enable power to interface modules, see “Disabling and re-enabling power to interface
modules” on page 211
The intra-building ports of the equipment or subassembly are suitable for connection to intra-building or
unexposed wiring or cabling only. The intra-building ports of the equipment or subassembly MUST NOT be
metallically connected to interfaces that connect to the outside plant (OSP) or its wiring. These ports are
designed for use as intra-building interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE,
Issue 5) and require isolation from the exposed OSP cabling. The addition of Primary Protectors is not
sufficient protection to connect these interfaces metallically to OSP wiring.
The following table provides the router slot numbers into which you must install the modules. Markings for the router slots are at the base
of the slots.

NI-MLX-1Gx48-T interface modules in 16-slot routers
If you install NI-MLX-10Gx8-M, NI-MLX-10Gx8-D or NI-MLX-1Gx48-T-A interface modules in a 16-slot router, you must replace the
standard fans on the back of the router with high speed fans. You must also replace standard switch fabric modules with high-speed
switch fabric modules.
For power supply requirements for NI-MLX-1Gx48-T-A interface modules, refer to “Hardware Specifications”.
NI-MLX-1Gx48-T interface modules cannot be installed in slots 2, 12, 14, and 15 in a 16-slot router. NI-MLX-1Gx48-T-A modules do not
have any slot restrictions.
When one or more NI-MLX-1GX48-T-A modules are installed in an MLX16-slot router, you must replace the NI-X-16-FAN-EXH
modules with NIBI-16-FAN-EXH-A high-speed fan modules. For more information about high-speed fan modules, see
“NIBI-16-FAN-EXH-A high-speed fan assemblies” on page 39. If the 16-slot router is not upgraded to support NIBI-16-FAN-EXH-A
modules before NI-MLX-1GX48-T-A modules are installed, the following Syslog message is displayed.
