Installing a Brocade MLX-4 router
3
Before installing modules in the Brocade MLX-4 router, have the following items available:
• A large flat-blade screwdriver
• An ESD wrist strap with a plug for connection to the ESD connector on the router chassis
DANGER
For safety reasons, the ESD wrist strap should contain a 1 megohm series resistor.
You can install modules 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.
The Brocade MLX-4 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 into
a slot.
CAUTION
If you do not install a module in a slot, you must leave the slot blank installed. If you operate the
router with an uncovered slot, the system may overheat.
Although the slot blanks differ in size, the procedure for removing them is identical. You will need a
flat-blade screwdriver to remove slot blanks.
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 these steps to remove a slot blank.
1. Loosen the screws on either end of the slot blank by hand or with a flat-blade screwdriver.
2. Pull the slot blank out of the router, and store it in a safe place for future use.
Follow this procedure to install a new interface module in the router.
1. If you are installing a module in a slot which may have been configured for a different module
type, remove the old configuration information by following these steps.
a. Use the show running-config command in config mode to determine the current
configuration of the slot.
