Installing a Brocade MLX Router : Installing a Brocade MLX-16 router

Installing a Brocade MLX-16 router
This section describes how to install a Brocade MLX-16 router.
Preparing the installation site
Before installing the router, plan the location and orientation relative to other devices and equipment. For cooling purposes, allow a minimum of six inches of space between the sides, front, and the back of the router and walls or other obstructions. If a router is installed in a perforated enclosure, the perforations must cover at least 60 percent of the surface.
Ensure that the proper power and network cabling is installed at the site. For information about cabling, refer to “Installing Brocade MLX-16 router power supplies”, “Attaching a management station”, and “Connecting the router to a network device”.
Unpacking a Brocade MLX-16 router
The Brocade MLX-16 router ships with the following items:
If any of these items are missing, contact the place of purchase.
Remove your Brocade MLXe-16 router from the shipping carton. Save the shipping carton and packing materials in case you need to move or ship the router at a later time.
Lifting guidelines for Brocade MLX-16 routers
* DANGER: A fully-populated Brocade MLX-16 device is heavy. TWO PEOPLE ARE REQUIRED WHEN LIFTING, HANDLING, OR MOUNTING THESE DEVICES.
Follow these guidelines for lifting and moving your Brocade MLX-16 router:
Installing a Brocade MLX-16 router in a rack
* DANGER: Make sure the rack or cabinet housing the device is adequately secured to prevent it from becoming unstable or falling over.
* DANGER: Mount the devices you install in a rack or cabinet as low as possible. Place the heaviest device at the bottom and progressively place lighter devices above.
You can install up the three Brocade MLX-16 routers in a standard 19-inch (EIA310-D) rack. It is recommended that you install your router in a rack before you install any router components.
You can install the routers in either a front-mount configuration (using the factory-installed mounting brackets) or a mid-mount configuration. For a mid-mount configuration, simply remove the factory-installed mounting brackets from the front edges of the device and re-attach them to the center sides of the device using the pre-drilled holes.
Follow these steps to mount a Brocade MLX-16 router in a rack.
NOTE: You must provide standard #12-24 pan-head screws to mount each router in a rack. You will need a Phillips screwdriver to perform this task.
1.
2.
Position four mounting screws for each router according to the spacings of the keyhole slots (the ones with the narrow portion pointing up) on the mounting brackets, as shown in Figure 49. When tightening the mounting screws, leave approximately 1/4 inch of clearance between the back of the screw head and the rack posts.
Figure 49 Positioning the mounting screws in the rack posts
 
3.
Starting at the bottom of the rack, mount the router as shown in Figure 50. With two or more people lifting the router, slip the wide portion of each keyhole slot over the corresponding mounting screw in the rack post.
Figure 50 Mounting the Brocade MLX-16 router in a rack
 
4.
5.
NOTE: For better grounding of the router to the rack, attach the router using star washers. You should also use star washers with any single-hole grounding lugs to keep the lugs from rotating.
Repeat step 2 through step 5 to mount each router in the rack.
Installing Brocade MLX-16 router modules
The Brocade MLX-16 router ships with the required switch fabric modules installed.
The installation sequence for multiple modules is important to ensure proper fit. Always fill the bottom slots in the Brocade MLX-16 router first. Begin by filling the slots from the left side of the router, and work towards the right side. Refer to Figure 3 for slot locations.
Follow this installation sequence:
1.
2.
3.
4.
5.
6.
7.
8.
NOTE: When installing a module in an empty device (with all slots covered by filler panels), first slightly loosen the screws on all of the filler panels. If you do not loosen all of the filler panel screws, the fit will be too tight when you install a module.
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” and “Installing Brocade MLX-16 router modules”.
For instructions about installing 100xGbE interface modules, refer to “Installing 2x100GbE interface modules in Brocade MLX routers”.
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”
* DANGER: 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.
Table 20 provides the router slot numbers into which you must install the modules. Markings for the router slots are at the base of the slots.
 
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
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 Chapter 8, “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.
SYSLOG: Mar 26 14:19:53:<12>R1, 48X1G modules in slots 10,11,13,16 shouldn't be running without high speed fans.
The NIBI-16-FAN-EXH-A fan module does not ship with some Brocade MLXe-16 routers. Contact Brocade to purchase this module.

If you are installing a redundant management module, refer to the chapter titled “Using a Redundant Management Module” in the Brocade MLX Series and Brocade NetIron Family Configuration Guide for information about how the redundant module works, optional software configurations that you can perform, and how to manage the redundancy feature.
NOTE: Brocade MLX modules are dedicated, which means that you must install them in a Brocade MLX router only. If you install a Brocade MLX module in another Brocade device or install a module intended for another Brocade device in a Brocade MLX router, the router and module may not function properly.

Although management modules are designed to be hot-swappable, you must upgrade the software on all interface modules and management modules to the appropriate software release before installing them. For more information on the appropriate software release, refer to the Hardware Installation Notes that shipped with the management module.
Before installing modules in the Brocade MLX-16 router, have the following items available:
* DANGER: For safety reasons, the ESD wrist strap should contain a 1 megohm series resistor.
The Brocade MLX-16 router ships with slot blanks installed in all empty module slots. The slot blanks help ensure proper airflow inside the router. You must remove the slot blank to install a module in a slot.
* CAUTION: If you do not install a module in a slot, you must keep the slot blank in place. If you run the device with an uncovered slot, the system may overheat. Tighten the screws that secure the slot blanks so that they remain in place when removing adjacent panels or modules.
Although the slot blanks differ in size, the procedure for removing them is identical. You will need a flat-blade screwdriver to perform this task.
Follow these steps to remove a slot blank.
1.
2.
* CAUTION: If you are hot-swapping a module, allow a minimum of two seconds after a module (or power supply or fan tray) has been removed before inserting a module in the same slot.
Follow this procedure to install an interface module, management module, or switch fabric module in the Brocade MLX-16 router
