Installation Guide

NOTE
MLX Series router modules are dedicated, which means that you must install them in MLX Series routers only. If you install a
MLX Series module in another Extreme router or install a module intended for another Extreme router in an MLX Series router,
the router and module may not function properly. Even though management modules are designed to be hot-swappable, you
must upgrade the software on all interface modules and management modules to the appropriate Extreme NetIron 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.
For information about how to disable and re-enable power to interface modules, refer to Disabling and re-enabling power to interface
modules on page 224.
Before installing modules in the MLXe-16 router, have the following items available:
• A large at-blade screwdriver.
• A new or replacement interface module, which you can order from Extreme Networks.
• An ESD wrist strap with a plug to attach to the ESD connector on the router chassis.
DANGER
For safety reasons, the ESD wrist strap should contain a series 1 megaohm resistor.
NOTE
Use of a power screwdriver may twist the heads from the screws and is not recommended.
CAUTION
If you do not install a module or a power supply in a slot, you must keep the slot ller panel in place. If you run the chassis
with an uncovered slot, the system will overheat.
Reset fan speed to auto
For MLXe-16 routers, if you insert a module into a slot where the fan speed for a previous module was manually
congured, you will
need to change the fan speed back to auto. For example, if the fan speed was manually congured to "slow", and you are installing a
module that requires more cooling power, the "slow" setting will cause the module to overheat. To congure the fan speed to auto, enter
the following command:
device # set-fan-speed auto
The MLXe-16 router ships with slot blanks installed in all empty module slots. The slot blanks help ensure proper airow inside the
router. You must remove the slot blank to install a module in a slot.
Although the slot blanks dier in size, the procedure for removing them is identical. You will need a at-blade screwdriver to perform this
task.
Follow these steps to remove a slot blank.
1. Loosen the screws on either end of the slot blank by hand or with a at-blade screwdriver.
2. Pull the slot blank out of the router and store it in a safe place for future use.
NOTE
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 modules in the router.
