NOTE
MLX Series modules are dedicated, which means that you must install them in MLX Series routers only. If you install a MLX
Series module in a non- MLX Series router, or install a module intended for a non- MLX Series router in a MLX Series router,
the router and module will 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.
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.
Modules must be installed in the correct slot number, as shown in the following list. First the slot number is shown, then the module into
which it must be installed. An identifying label can be seen at the base of each slot.
NOTE
The MLXe-4 router ships with the required switch fabric modules installed.
1. Management modules
2. Active module - M1 (left).Redundant module - M2 (right).
3. Interface modules
4. - 4
5. Switch fabric modules
6. SF1 - SF3
If you are installing a redundant management module, refer to the chapter titled "Using a Redundant Management Module" in the MLX
Series and Extreme NetIron Family Conguration Guide for information about how the redundant module works, optional software
congurations, and how to manage redundancy.
You can install modules while the router is powered on and running.
Before installing a new interface module, you will need to remove the slot blank from the module slot. You should also have the following
items available:
A 1/4 inch #8 at-blade screwdriver, or a #2 Phillips screwdriver
A new interface module, which you can order from Extreme Networks.
An ESD wrist strap with a plug for connection to the ESD connector on the MLX Series router.
DANGER
For safety reasons, the ESD wrist strap should contain a series 1 megaohm resistor.
The MLXe-4 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 into a slot.
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.
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.
